Product Description
CMT Boring Bit Adapter - D10 with M10 Right-Hand Threaded Shank by CMT is a precision-machined spindle adapter designed to connect dowel drill bits to multi-spindle boring machine spindles and panel processing centers. With a 19.5mm body diameter and a 10mm threaded bore, this adapter delivers a secure, concentric interface between the machine spindle and the cutting tool - reducing runout and maintaining drilling accuracy across high-volume production runs. The right-hand rotation design matches the standard drive direction of CNC boring machines, making it a reliable choice for cabinet makers, furniture manufacturers, and woodworking shops that depend on consistent dowel hole placement.
Key Features
- M10 right-hand threaded shank (10mm diameter) - engages securely with standard multi-spindle boring machine spindles, preventing loosening during operation and maintaining tool alignment throughout the cut.
- 19.5mm body diameter - provides a robust, stable shoulder that resists flex and vibration during repeated drilling cycles, supporting accurate and repeatable hole positioning.
- 10mm bore diameter - sized to accept 10mm shank dowel drill bits, allowing direct, tool-free bit changes on compatible boring machine spindles.
- Right-hand (RH) rotation - matches the standard spindle direction on CNC boring machines, multi-spindle boring machines, and panel processing centers, ensuring safe engagement without reverse-threading risk.
- Compact, purpose-built adapter design - bridges the gap between machine spindle threads and boring bit shanks, eliminating the need for non-standard tooling setups and keeping changeover time to a minimum.
Why This Product
- Solves the spindle-to-bit interface problem - when a boring machine spindle uses an M10 threaded connection but the application demands a 10mm shank boring bit, this adapter provides the precise mechanical link needed without custom fabrication or workarounds.
- Right-hand rotation is correctly matched - the RH thread direction ensures the adapter tightens under load rather than backing out, which is critical for maintaining consistent hole depth and position in production environments.
- Engineered dimensions for accurate alignment - the 19.5mm body diameter and 10mm bore are dimensionally precise, supporting the close tolerances required for dowel drilling in cabinet and furniture panel processing.
- Broad machine compatibility - suited for use on CNC boring machines, multi-spindle boring machines, and panel processing centers, making it a versatile adapter for shops running a variety of boring equipment.

Frequently Asked Questions
What size shank does this adapter use?
This adapter features an M10 right-hand threaded shank with a 10mm diameter, designed to thread directly into compatible multi-spindle boring machine spindles.
What bore diameter does this adapter accept?
The bore diameter is 10mm, sized to receive 10mm shank boring bits for use in dowel drilling and panel boring applications.
Is this adapter suitable for left-hand rotation spindles?
No. This adapter is designed for right-hand (RH) rotation only. Using it on a left-hand rotation spindle would cause the threaded connection to loosen under load, which is unsafe and not recommended.
What is the overall body diameter of this adapter?
The body diameter is 19.5mm. This dimension determines clearance requirements when mounting the adapter in a multi-spindle boring head alongside adjacent spindles.
