Product Description
CMT Bushing for Twist Drill - 5/64" Bore Diameter by CMT is a precision-ground mounting bushing designed to securely seat CMT 363 solid carbide twist drills into CMT 364 adapters for use on boring machine spindles. With a 2mm bore diameter, 23mm total length, and a 10mm shank, this compact bushing delivers the accurate fit needed for consistent hole placement on CNC boring machines and multi-spindle boring centers. Whether you are equipping a production shop or maintaining a boring center, this bushing provides the reliable interface between drill and adapter that keeps operations running smoothly.
Key Features
- 2mm Bore Diameter (5/64") - matches the shank of CMT 363 solid carbide twist drills precisely, eliminating play and ensuring accurate, repeatable drill positioning during boring operations.
- 23mm Total Length - provides the appropriate depth engagement within the CMT 364 adapter, giving the twist drill stable support across its mounted length and reducing vibration during use.
- 10mm Shank - fits securely into the CMT 364 adapter, creating a solid, concentric connection between the drill and the boring machine spindle for dependable performance.
- Precision-Ground Construction - tight tolerances on all mating surfaces mean the bushing seats consistently every time, supporting accurate hole placement critical in cabinet and furniture production environments.
- Part of the CMT 365 Bushing System - works as a dedicated component within the CMT 363/364/365 system, simplifying drill setup and ensuring component compatibility without guesswork.
Why This Product
- Designed specifically to pair with CMT 363 solid carbide twist drills and CMT 364 adapters, this bushing eliminates the need to source mismatched third-party components that can compromise fit and hole accuracy on boring spindles.
- The 5/64" (2mm) bore is precision-ground to match the drill shank dimension exactly, giving woodworkers and shop operators confidence that each hole location will be consistent across high-volume boring runs.
- At 23mm total length and a 10mm shank, the bushing is sized to provide full, stable support of the twist drill within the adapter - reducing runout and extending the working life of both the bushing and the drill.
- As an active CMT replacement and setup component, this bushing allows shops to maintain or expand their boring machine configurations without replacing entire drill assemblies when a single bushing is all that is needed.
