Product Description
CMT Bushing for Twist Drill - 9/64" Bore Diameter is a precision-ground mounting bushing designed to securely seat CMT 363 solid carbide twist drills into CMT 364 adapters, enabling accurate installation on boring machine spindles. With a 3.5mm bore diameter, 23mm total length, and 10mm shank, this bushing provides a reliable interface between your twist drill and the boring spindle - keeping drill positioning consistent and eliminating play during high-cycle boring operations. Whether you are equipping a CNC boring machine or a multi-spindle boring center, this bushing is an essential component for a complete and stable drill mounting assembly.
Key Features
- 3.5mm Bore Diameter (9/64") - matches the shank of CMT 363 solid carbide twist drills precisely, ensuring a snug, wobble-free fit that preserves bore accuracy and extends drill life.
- 23mm Total Length - provides sufficient engagement depth within the CMT 364 adapter to maintain rigid drill support during repeated boring cycles, reducing the risk of drill deflection.
- 10mm Shank - sized to interface correctly with the CMT 364 adapter system, making the bushing a direct, tool-free drop-in component in a properly configured spindle setup.
- Precision-Ground Construction - delivers tight dimensional tolerances that translate directly into repeatable bore placement, critical for furniture production, cabinet making, and panel processing applications.
- Works as Part of the CMT 363 / 364 / 365 System - the bushing completes the three-part mounting solution, allowing CMT 363 twist drills to be mounted and dismounted efficiently on boring spindles without improvised adapters or fitment issues.
Why This Product
- Designed specifically for the CMT 363 solid carbide twist drill system, this bushing eliminates the guesswork of adapter compatibility - everything is engineered to work together from the start.
- The 9/64" (3.5mm) bore matches the CMT 363 drill shank with precision-ground accuracy, which means your boring positions stay consistent run after run - important for high-volume panel and cabinet production.
- At 23mm in total length with a 10mm shank, the bushing provides enough contact surface area to hold drills firmly under the load of multi-spindle boring operations, reducing vibration and positional drift.
- Replacing or adding drill positions in a CMT 364 adapter setup is straightforward with this bushing - it is an individually available component, so you can service or expand your boring head without replacing the entire assembly.
