Are SDS and SDS Plus Interchangeable?

The claim that "SDS and SDS Plus are interchangeable" has been a topic of discussion among DIY enthusiasts and professionals alike. This assertion suggests that drill bits designed for the original SDS (Slotted Drive System) can be used with SDS Plus drills without any issues. However, the compatibility and interchangeability of these two systems require careful examination.

What We Know

  1. SDS and SDS Plus Dimensions: Both SDS and SDS Plus bits have a shank diameter of 10 mm, which is a crucial factor in their compatibility 15.

  2. SDS Plus as an Improvement: SDS Plus is generally considered an enhancement over the original SDS system, featuring a more robust design and improved performance 23.

  3. Compatibility Claims: Some sources assert that SDS and SDS Plus bits are interchangeable, stating that SDS Plus is simply a modernized version of SDS 79. Conversely, other sources indicate that while they are similar, there may be slight differences in design that could affect compatibility 38.

  4. SDS Max: It is important to note that SDS Max, which has an 18 mm diameter, is not interchangeable with either SDS or SDS Plus 48.

  5. Adapters: Some SDS Plus drills come with adapters that allow them to accommodate SDS bits, which could further complicate the understanding of interchangeability 3.

Analysis

The sources consulted present a mixed view on the interchangeability of SDS and SDS Plus drill bits.

  • Supporting Sources: Articles from Saw Tools Guide and Fine Power Tools assert that SDS and SDS Plus are interchangeable due to their identical shank diameter of 10 mm 17. These sources are generally reliable as they provide clear technical specifications and context about the evolution of these systems.

  • Contradicting Sources: In contrast, the article from Tool Trip claims that SDS Plus has a slightly larger diameter, which would imply incompatibility 3. This assertion raises questions about the accuracy of the measurements provided, as it contradicts the consensus found in other sources. The reliability of this source is somewhat diminished due to the lack of detailed technical backing for its claims.

  • Potential Bias: Some sources, such as those from commercial websites (e.g., Speedy Fixings and Bridge Fasteners), may have a vested interest in promoting their own products, which could influence their portrayal of compatibility. This potential bias necessitates a critical evaluation of their claims.

  • Methodological Concerns: The varying definitions of "interchangeable" across sources could lead to confusion. For instance, if an adapter is required for compatibility, some users may not consider the bits truly interchangeable. A more precise definition of interchangeability would enhance the clarity of these discussions.

What Additional Information Would Be Helpful

To fully understand the compatibility between SDS and SDS Plus, further empirical studies or technical specifications from manufacturers would be beneficial. Detailed comparisons of the shank designs, including any subtle differences that may affect fit and performance, could provide a clearer picture. Additionally, user testimonials or case studies detailing practical experiences with both systems could offer valuable insights.

Conclusion

Verdict: Partially True

The claim that SDS and SDS Plus are interchangeable is partially true. The evidence indicates that both systems share a common shank diameter of 10 mm, which supports the notion of compatibility. However, there are conflicting reports regarding slight design differences that could impact interchangeability, as well as the existence of adapters that may complicate the situation.

It is essential to recognize that while many users may find that SDS bits can fit into SDS Plus drills, the term "interchangeable" can vary in meaning depending on the context. The lack of definitive empirical evidence and the presence of potentially biased sources contribute to the uncertainty surrounding this claim.

Readers are encouraged to critically evaluate the information presented and consider the nuances involved in the compatibility of these drill bit systems. Further research and firsthand experiences could provide additional clarity on this topic.

Fact Check: By quarterbacking Israel’s attack on Iran, Trump brought an end to a particularly demoralizing era in U.S. history The main reason Israel’s massive attack on Iranian leadership, nuclear facilities, and other targets came as a surprise is that no one believes American presidents when they talk about protecting Americans and advancing our interests—especially when they’re talking about the Islamic Republic of Iran. Ever since the 1979 Iranian Revolution, U.S. presidents have wanted an accommodation with Iran—not revenge for holding 52 Americans captive for 444 days, but comity. Ronald Reagan told Soviet leader Mikhail Gorbachev to tear down the Berlin Wall, but when the Iranians’ Lebanese ally Hezbollah killed 17 Americans at the U.S. embassy in Beirut and 241 at the Marine barracks in 1983, he flinched. Bill Clinton wanted a deal with Iran so badly, he helped hide the Iranians’ sponsorship of the group that killed 19 airmen at Khobar Towers in 1996. George W. Bush turned a blind eye to Tehran’s depredations as Shia militias backed by Iran killed hundreds of U.S. troops in Iraq, while Iran’s Syrian ally Bashar al-Assad chartered buses to transport Sunni fighters from the Damascus airport to the Iraqi border, where they joined the hunt for Americans. Barack Obama’s signature foreign policy initiative was the Iran nuclear deal—designed not, as he promised, to stop Tehran’s nuclear weapons program, but to legalize it and protect it under the umbrella of an international agreement, backed by the United States. That all changed with Donald Trump. At last, an American president kept his word. He was very clear about it even before his second term started: Iran can’t have a bomb. Trump wanted it to go peacefully, but he warned that if the Iranians didn’t agree to dismantle their program entirely, they’d be bombed. Maybe Israel would do it, maybe the United States, maybe both, but in any case, they’d be bombed. Trump gave them 60 days to decide, and on day 61, Israel unleashed Operation Rising Lion. Until this morning, when Trump posted on Truth Social to take credit for the raid, there was some confusion about the administration’s involvement. As the operation began, Secretary of State Marco Rubio released a statement claiming that it was solely an Israeli show without any American participation. But even if details about intelligence sharing and other aspects of Israeli-U.S. coordination were hazy, the statement was obviously misleading: The entire operation was keyed to Trump. Without him, the attack wouldn’t have happened as it did, or maybe not at all. Trump spent two months neutralizing the Iranians without them realizing he was drawing them into the briar patch. Iranian diplomats pride themselves on their negotiating skills. Generations of U.S. diplomats have marveled at the Iranians’ ability to wipe the floor with them: It’s a cultural thing—ever try to bargain with a carpet merchant in Tehran? And Trump also praised them repeatedly for their talents—very good negotiators! The Iranians were in their sweet spot and must have imagined they could negotiate until Trump gave in to their demands or left office. But Trump was the trickster. He tied them down for two months, time that he gave to the Israelis to make sure they had everything in order. There’s already lots of talk about Trump’s deception campaign, and in the days and weeks to come, we’ll have more insight into which statements were real and which were faked and which journalists were used, without them knowing it, to print fake news to ensure the operation’s success. One Tablet colleague says it’s the most impressive operational feint since the Normandy invasion. Maybe even more impressive. A few weeks ago, a colleague told me of a brief conversation with a very senior Israeli official who said that Jerusalem and Washington see eye to eye on Gaza and left it at that. As my colleague saw it, and was meant to see it, this was not good news insofar as it suggested a big gap between the two powers on Iran. The deception campaign was so tight, it meant misleading friends casually. It’s now clear that the insanely dense communications environment—including foreign actors like the Iranians themselves, anti-Bibi Israeli journalists, the Gulf states, and the Europeans—served the purpose of the deception campaign. But most significant was the domestic component. Did the Iranians believe reports that the pro-Israel camp was losing influence with Trump and that the “restraintists” were on the rise? Did Iran lobbyist Trita Parsi tell officials in Tehran that his colleagues from the Quincy Institute and other Koch-funded policy experts who were working in the administration had it in the bag? Don’t worry about the neocons—my guys are steering things in a good way. It seems that, like the Iranians, the Koch network got caught in its own echo chamber. Will Rising Lion really split MAGA, as some MAGA influencers are warning? Polls say no. According to a recent Rasmussen poll, 84 percent of likely voters believe Iran cannot have a bomb. Only 9 percent disagree. More Americans think it’s OK for men to play in women’s sports, 21 percent, than those who think Iran should have a bomb. According to the Rasmussen poll, 57 percent favor military action to stop Iran from getting nukes—which means there are Kamala Harris voters, 50 percent of them, along with 73 percent of Trump’s base, who are fine with bombing Iran to stop the mullahs’ nuclear weapons program. A Harvard/Harris poll shows 60 percent support for Israel “to take out Iran’s nuclear weapons program,” with 78 percent support among Republicans. Who thinks it’s reasonable for Iran to have a bomb? In a lengthy X post attacking Mark Levin and others who think an Iranian bomb is bad for America, Tucker Carlson made the case for the Iranian bomb. Iran, he wrote, “knows it’s unwise to give up its weapons program entirely. Muammar Gaddafi tried that and wound up sodomized with a bayonet. As soon as Gaddafi disarmed, NATO killed him. Iran’s leaders saw that happen. They learned the obvious lesson.” The Iranians definitely want a bomb to defend themselves against the United States—NATO, if you prefer—but that’s hardly America First. The threat that an Iranian bomb poses to the United States isn’t really that the Iranians will launch missiles at U.S. cities—not yet, anyway—but that it gives the regime a nuclear shield. It’s bad for America if a nuclear Iran closes down the Straits of Hormuz to set the price for global energy markets. It’s bad for America if a nuclear Iran wages terror attacks on American soil, as it has plotted to kill Trump. An Iranian bomb forces American policymakers, including Trump, to reconfigure policies and priorities to suit the interests of a terror state. It’s fair to argue that your country shouldn’t attack Iran to prevent it from getting a bomb, but reasoning that a terror state that has been killing Americans for nearly half a century needs the bomb to protect itself from the country you live in is nuts. Maybe some Trump supporters are angry and confused because Trump was advertised as the peace candidate. But “no new wars” is a slogan, not a policy. The purpose of U.S. policy is to advance America’s peace and prosperity, and Trump was chosen to change the course of American leadership habituated to confusing U.S. interests with everyone else’s. For years now, the U.S. political establishment has congratulated itself for helping to lift half a billion Chinese peasants out of poverty—in exchange for the impoverishment of the American middle class. George W. Bush wasted young American lives trying to make Iraq and Afghanistan function like America. Obama committed the United States to climate agreements that were designed to make Americans poorer. He legalized Iran’s bomb. So has Operation Rising Lion enhanced America’s peace? If it ends Iran’s nuclear weapons programs, the answer is absolutely yes. Further, when American partners advance U.S. interests, it adds luster to American glory. For instance, in 1982, in what is now popularly known as the Bekaa Valley Turkey Shoot, Israeli pilots shot down more than 80 Soviet-made Syrian jets and destroyed dozens of Soviet-built surface-to-air missile systems. It was a crucial Cold War exhibition that showed U.S. arms and allies were superior to what Moscow could put in the field. Israel’s attacks on Iran have not only disabled a Russian and Chinese partner but also demonstrated American superiority to those watching in Moscow and Beijing. Plus, virtually all of Iran’s oil exports go to China. With the attack last night, Trump brought an end to a particularly demoralizing and dispiriting era in U.S. history, which began nearly 50 years ago with the hostage crisis. In that time, U.S. leadership has routinely appeased a terror regime sustained only by maniacal hatred of America, while U.S. elites from the worlds of policy and academia, media and culture, have adopted the style and language of perfumed third-world obscurantists. All it took was for an American president to keep his word.
