Product Description
The CMT 346.120.11 Dowel Drill with Threaded Shank is a precision-engineered boring tool designed for fast, clean dowel hole production in solid wood, chipboard, MDF, and a wide range of engineered panel materials. Built with a carbide-tipped (TCT) cutting edge and an M10 threaded shank for direct spindle mounting, this 12mm right-hand drill delivers flat-bottom bores with minimal tearout - making it a reliable choice for cabinet manufacturers, furniture producers, and panel processing operations running multi-spindle boring machines.
Key Features
- Carbide-Tipped (TCT) Construction - tungsten carbide cutting edges maintain sharpness through high-volume production runs in abrasive materials like chipboard, MDF, and coated panels, reducing the frequency of tool changes.
- M10 Threaded Shank - mounts directly onto multi-spindle boring machines without an adapter, saving setup time and reducing the number of components needed at the spindle.
- Right-Hand (RH) Rotation - optimized for standard spindle configurations on CNC boring centers and panel processing equipment, ensuring compatibility with the most common machine setups.
- 2 Precision-Ground Spurs - score the material perimeter before the main cutters engage, producing clean bore walls and flat-bottom holes with no rough edges or fiber tearout - critical for visible face-panel work.
- 2-Flute Design with 43mm Cutting Height - the generous cutting height accommodates varying panel thicknesses and allows for consistent chip evacuation, keeping the bore clean during continuous cycling.
- 63mm Relative Length - provides adequate clearance for spindle positioning on multi-row boring heads without interfering with adjacent tooling.
- HW (Hard Metal / Carbide) Material Grade - a proven grade for woodworking applications that balances hardness and toughness, delivering consistent hole quality across dense and abrasive engineered wood products.
Why This Product
- The M10 threaded shank mounts directly to compatible boring machine spindles with no adapter required, cutting setup time and eliminating an extra point of potential runout or misalignment.
- With a 12mm diameter, 43mm cutting height, and 2-spur geometry, this drill produces the precise, flat-bottom holes required for dowel joinery in cabinet carcasses, furniture panels, and shelving components.
- The carbide-tipped cutting edges and 2-flute configuration handle the abrasive nature of chipboard, MDF, and coated panels without rapid dulling - supporting higher throughput in production environments.
- Right-hand rotation matches the standard spindle direction on the vast majority of CNC boring centers and multi-spindle panel processing machines, making this a straightforward drop-in solution for common production setups.

Frequently Asked Questions
What type of shank does the CMT 346.120.11 use, and does it require an adapter?
This drill uses an M10 threaded shank that mounts directly onto compatible multi-spindle boring machine spindles without requiring an adapter. This direct-mount design simplifies setup and reduces potential for runout caused by intermediate adapter components.
What diameter hole does this bit drill, and what is its maximum cutting height?
The CMT 346.120.11 drills a 12mm diameter hole. Its cutting height is 43mm, which accommodates a range of panel thicknesses commonly encountered in cabinet and furniture panel production.
Is this dowel drill compatible with left-hand spindle rotation?
No. This bit is designed exclusively for right-hand (RH) rotation. It should only be used on machine spindles configured for right-hand (clockwise) rotation. Using it on a left-hand spindle will damage the tooling and produce poor results.
What materials can the CMT 346.120.11 bore through?
This dowel drill is suitable for use in solid wood (hardwood and softwood), chipboard, MDF, HDF, plywood, laminates, and coated panels. Its carbide-tipped (TCT) cutting edges are well suited to the abrasive nature of engineered wood products used in high-volume panel processing applications.
