Product Description
CMT Bushing for Twist Drill - 13/64" Bore Diameter is a precision-ground mounting bushing designed to securely seat CMT 363 solid carbide twist drills onto boring machine spindles. Working in tandem with CMT 364 adapters, this bushing provides a reliable, accurate interface between the twist drill and the spindle, ensuring consistent hole placement and stable operation during multi-spindle or CNC boring applications. With a 5mm bore diameter, a 10mm shank, and a total length of 23mm, the CMT 365.050.00 delivers the dimensional precision that woodworking professionals and production shops depend on.
Key Features
- 13/64" (5mm) Bore Diameter - matches the shank of compatible CMT 363 solid carbide twist drills exactly, eliminating slop or runout that could compromise hole accuracy on boring machines.
- 10mm Shank - sized to seat firmly within CMT 364 adapters, providing a secure, repeatable connection between the drill and the spindle without additional modification.
- 23mm Total Length - compact profile keeps the drill positioned close to the spindle, maintaining rigidity and reducing vibration during operation.
- Precision-Ground Construction - ensures accurate, consistent mounting of CMT 363 twist drills, supporting tight tolerance work in production boring environments such as CNC boring machines and multi-spindle boring centers.
- Designed for Use with CMT 364 Adapter - the 365 bushing and 364 adapter work as a complete system, giving operators a straightforward, purpose-built solution for mounting twist drills on boring machine spindles.
Why This Product
- Engineered specifically as part of the CMT 363/364/365 system, this bushing removes the guesswork from drill mounting - every component is designed to work together for a secure, accurate fit on boring machine spindles.
- The 5mm bore diameter and 10mm shank dimensions are precision-ground to eliminate runout, making this bushing a practical choice for production shops where consistent hole quality across every spindle position is critical.
- At 23mm total length, the bushing keeps the drill assembly compact and rigid, which helps maintain boring accuracy during high-volume runs on CNC boring machines or multi-spindle boring centers.
- Compatibility with CMT 364 adapters means this bushing integrates directly into an existing CMT tooling setup without requiring additional hardware or custom modifications.
