Product Description
CMT Adapter and Bushing for Twist Drill - 3x38mm is a precision-engineered mounting solution designed to secure CMT twist drills onto boring machine spindles with accuracy and confidence. Built to work with CMT 364-365 series twist drills, this adapter accepts a 3mm bore diameter and features a 10x20mm parallel shank with a driving flat, making it compatible with standard 10mm boring machine spindle systems. Whether you are running a CNC boring machine or a multi-spindle boring center, this bushing delivers the secure, repeatable fit that production woodworking demands.
Key Features
- 3mm bore diameter - precisely matches CMT 363 series twist drills so the bit seats fully and runs true without wobble or play
- 10x20mm parallel shank with driving flat - provides positive rotational engagement with standard boring machine spindles, preventing slippage under load
- 1 1/2 in. total length - compact profile keeps the drill positioned correctly relative to the workpiece, maintaining accurate depth control
- Premium quality HWM (hard metal) construction - delivers the durability and wear resistance needed for continuous production environments
- 2 precision ground cutting edges (Z2) - ensures clean, accurate entry into the workpiece and consistent hole quality across all cuts
- 2 spiral flutes - promote efficient chip evacuation during drilling, reducing heat buildup and keeping the cutting zone clear
- Precision relief geometry - reduces friction and heat at the cutting edge, extending the life of both the adapter and the installed drill
- Designed for use with CMT 364-365 series items - ensures a verified, system-matched fit rather than a generic aftermarket guess
Why This Product
- System-matched compatibility with CMT 364-365 twist drills means you get a verified fit engineered by the same manufacturer - no adapting, shimming, or guessing required for reliable boring performance
- The 10x20mm parallel shank with driving flat targets standard boring machine spindles directly, so this bushing installs quickly into CNC boring machines and multi-spindle boring centers without modification
- Precision ground cutting geometry and spiral flute design work together to produce clean, repeatable holes in chipboard, MDF, hardwood, softwood, plywood, and laminates - covering the full range of sheet goods and solid wood found in cabinet and furniture production
- At 3mm bore diameter and 1 1/2 in. total length, this adapter is purpose-sized for fine boring work where exact positioning and depth consistency are critical to panel and joint quality
