Product Description
CMT 346.060.12 Dowel Drill with Threaded Shank - 6mm (15/64"), M10 Shank, Left-Hand Rotation by CMT is a precision-engineered boring bit designed for direct mounting to multi-spindle boring machines, CNC boring centers, and panel processing equipment. Built from tungsten carbide-tipped (HW) construction, this 2-flute dowel drill delivers clean, flat-bottom holes in solid wood, chipboard, MDF, and a wide range of panel materials. The M10 threaded shank enables tool-free adapter-free mounting directly into compatible spindles, making it a practical choice for high-volume cabinet and furniture production workflows.
Key Features
- Tungsten Carbide-Tipped (HW) Construction - hard carbide material maintains a sharp cutting edge through demanding production runs in chipboard, MDF, hardwood, and coated panels, reducing downtime from frequent bit changes.
- M10 Threaded Shank - threads directly into compatible multi-spindle boring machine spindles without an adapter, providing a secure, repeatable connection that keeps the bit aligned and eliminates adapter-related runout.
- Left-Hand (LH) Rotation - engineered specifically for left-hand spindle positions on multi-spindle boring machines, ensuring correct chip evacuation direction and clean entry cuts on the correct face of the workpiece.
- 2-Flute, 2-Spur Geometry - dual spurs score the perimeter of the bore before the flutes remove material, producing clean bore walls and flat-bottom holes with minimal tearout in finished and laminated panels.
- 6mm (15/64") Cutting Diameter - matches standard dowel hole sizing used in cabinet construction and furniture assembly, ensuring proper fit for 6mm dowel pins without additional sizing passes.
- 43mm Cutting Height with 63mm Relative Length - sufficient cutting depth for through-boring and deep pocket applications in standard panel thicknesses, while the compact overall length keeps the tool within typical machine clearance envelopes.
Why This Product
- The M10 threaded shank provides direct spindle engagement on multi-spindle CNC boring machines and boring centers - eliminating the need for adapters or chucks and reducing setup time between production runs.
- Left-hand rotation is purpose-built for LH spindle positions, meaning you get proper chip flow and clean entry cuts without improvising with a right-hand bit in the wrong spindle - a common source of tearout and poor hole quality.
- Tungsten carbide-tipped (HW) construction holds up to the abrasive demands of chipboard, MDF, and coated panels, materials that quickly dull standard steel bits and cause surface damage at bore entry and exit points.
- At 6mm diameter with 2 precision-ground spurs, this bit is sized and configured for standard dowel joinery applications in cabinet and furniture manufacturing, producing consistent, accurately sized holes for reliable dowel pin fit across repeated production cycles.

Frequently Asked Questions
What machines is this dowel drill compatible with?
This bit is designed for multi-spindle CNC boring machines, CNC boring centers, and panel processing centers that use M10 threaded spindles. The M10 threaded shank mounts directly into compatible left-hand spindle positions without an adapter.
Why does rotation direction matter when selecting a dowel drill?
Multi-spindle boring machines use both right-hand and left-hand spindles depending on spindle position. This bit is specifically ground for left-hand (LH) rotation. Using a bit with the wrong rotation direction in a given spindle will result in poor hole quality, excessive tearout, and potential damage to the workpiece or tool.
What materials can be drilled with this bit?
The tungsten carbide-tipped (HW) construction makes this bit suitable for chipboard, MDF, HDF, solid hardwood, softwood, plywood, laminates, and coated panels - materials commonly found in cabinet and furniture manufacturing.
What is the cutting depth capacity of this bit?
This dowel drill has a cutting height of 43mm and a relative length of 63mm. The 43mm cutting height defines the usable boring depth available for through-bore and deep pocket applications within standard panel thicknesses.
