Product Description
CMT 365.032.00 Bushing for Twist Drill - 1/8" Bore Diameter is a precision-ground mounting bushing designed to secure CMT 363 solid carbide twist drills onto boring machine spindles. Working in conjunction with CMT 364 adapters, this bushing delivers a tight, accurate fit that keeps drill bits properly aligned during operation - reducing runout and improving hole quality on CNC boring machines and multi-spindle boring centers. With a compact 10mm shank and 23mm total length, it integrates cleanly into standard boring setups where consistent, repeatable drill positioning is essential.
Key Features
- 1/8" (3.2mm) bore diameter - matches the shank of CMT 363 solid carbide twist drills exactly, ensuring a secure, wobble-free fit that maintains drilling accuracy
- 10mm shank diameter - fits standard CMT 364 adapter sockets, allowing fast and reliable installation onto boring machine spindles without modification
- 23mm total length - provides the correct projection depth for proper drill positioning within the adapter assembly, keeping the cutting tip at the right working height
- Precision-ground construction - tight tolerances mean the bushing seats consistently every time, reducing setup variation and supporting repeatable hole placement across multi-spindle operations
- Designed for use with CMT 364 adapters - the bushing and adapter work as a matched system, so the full drill mounting assembly functions as intended with no guesswork about compatibility
Why This Product
- For shops running CNC boring machines or multi-spindle boring centers, having the correctly sized bushing for each drill diameter eliminates slop in the spindle assembly - this 3.2mm bore bushing is the right fit for 1/8" twist drills and maintains the accuracy those machines are built to deliver.
- The bushing bridges the gap between the CMT 363 drill shank and the CMT 364 adapter, completing the mounting system so the drill is held firmly at the correct depth and angle - critical for production environments where every hole must hit the same mark.
- At 23mm total length and a 10mm shank, this bushing is sized to work within the geometry of the CMT adapter system without requiring any shimming, spacers, or custom fitting.
- Choosing a bushing designed specifically for this drill system - rather than a generic alternative - means the 3.2mm bore is ground to match the drill shank precisely, supporting long-term reliability and reducing wear on both the bushing and adapter.

Frequently Asked Questions
What drill does this bushing fit?
This bushing is designed for CMT 363 solid carbide twist drills with a 1/8" (3.2mm) shank diameter. It is not intended for use with drills outside the CMT 363 series.
Does this bushing work without a CMT 364 adapter?
No - the CMT 365.032.00 bushing is designed to work in conjunction with CMT 364 adapters. The bushing slides into the adapter, which then mounts the drill assembly onto the boring machine spindle. Both components are required for a complete installation.
What are the key dimensions of this bushing?
The bushing has a 3.2mm (1/8") bore diameter to accept the drill shank, a 10mm shank diameter that fits the CMT 364 adapter, and a total length of 23mm.
What types of machines is this bushing used with?
This bushing is used on CNC boring machines and multi-spindle boring centers where CMT 363 twist drills are mounted via CMT 364 adapters for high-precision drilling operations.
