Product Description
The CMT 550-SDS2 SDS Adaptor for Center Drills by CMT is a precision-engineered shank adaptor designed to connect CMT 550X and 551X series hole saws to SDS rotary hammer drills. With a right-hand rotation design and a total length of 3-3/4 in., this adaptor bridges the gap between standard center drill arbors and the SDS tool interface, giving tradespeople and contractors the flexibility to run CMT Push and Lock hole saws on their SDS rotary hammer - expanding the versatility of their existing drill equipment without switching tools.
Key Features
- SDS shank interface - fits directly into SDS rotary hammer drills, allowing the use of CMT Push and Lock hole saws on a tool platform built for power and speed in demanding materials
- Right-hand (RH) rotation - matches standard drilling direction so the adaptor works in sync with your rotary hammer drive for smooth, consistent cutting performance
- 13mm bore diameter - engineered to accept CMT center drill shanks with a secure, precise fit that minimizes wobble and keeps cuts on target
- 3-3/4 in. total length - provides the reach needed to clear the drill chuck and engage the hole saw arbor assembly properly during operation
- Compatible with CMT 550X and 551X hole saw series - purpose-built for these CMT product lines, ensuring a reliable, manufacturer-matched connection rather than a generic workaround
Why This Product
- Designed specifically for CMT 550X and 551X hole saw systems, this adaptor provides a manufacturer-matched connection that keeps your hole saw assembly running true - no improvised fitments or compatibility guesswork
- The SDS shank design unlocks rotary hammer compatibility for CMT Push and Lock hole saws, letting crews use high-torque SDS drills in applications where that extra power makes a difference
- Right-hand rotation and a precisely machined 13mm bore work together to deliver stable, vibration-reduced operation, reducing the chance of off-center holes or premature wear on the center drill
- At 3-3/4 in. in length, the adaptor offers the clearance geometry needed for proper engagement between the SDS drill and the hole saw arbor, making it a straightforward solution for contractors already working within the CMT hole saw ecosystem
