Product Description
CMT 346.100.11 Dowel Drill with Threaded Shank - 10mm (25/64") Diameter, M10 Shank, Right-Hand Rotation is a professional-grade boring bit engineered by CMT for high-volume panel processing and cabinetmaking applications. Designed with an M10 threaded shank for direct mounting to multi-spindle boring machines, this two-flute carbide-tipped dowel drill delivers clean, flat-bottom holes in solid wood, chipboard, and MDF without the need for an adapter. Whether you are running a CNC boring center or a traditional multi-spindle machine, this right-hand rotation bit is built for precision and productivity in demanding shop environments.
Key Features
- Tungsten Carbide (HW) Cutting Material - carbide-tipped construction provides long-lasting edge retention and reliable performance through dense panel materials like chipboard and MDF, reducing the frequency of tool changes in production settings.
- M10 Threaded Shank - mounts directly to multi-spindle boring machines without an adapter, simplifying setup, improving concentricity, and saving time during tooling changeovers.
- 10mm (25/64") Boring Diameter - precision ground to exact metric sizing for accurate dowel holes and repeatable results across large production runs.
- 43mm Cutting Height - provides sufficient depth capacity for standard dowel joint applications and system boring in cabinet and furniture panel work.
- 2 Spurs and 2 Flutes - the dual-spur geometry scores the material ahead of the cutting edge, producing clean bore walls and flat-bottom holes with minimal tearout or fiber lifting on coated and laminated panels.
- Right-Hand (RH) Rotation - matches the standard spindle direction of most multi-spindle CNC boring machines and boring centers, ensuring immediate compatibility with typical machine configurations.
- 63mm Relative Length - compact overall length designed for close spindle spacing on multi-spindle heads, allowing tight hole-pattern layouts common in cabinet box construction.
Why This Product
- The M10 threaded shank eliminates the need for an intermediate adapter or collet chuck, reducing runout and setup time on multi-spindle boring heads - a direct advantage in high-throughput panel processing environments.
- Carbide tipping (HW material grade) means the cutting edge holds up through abrasive engineered wood products like chipboard and MDF, where high-speed steel tooling wears rapidly and sacrifices hole quality.
- The 2-spur, 2-flute geometry is purpose-built for dowel boring - it shears material cleanly before excavating the bore, which is critical when working with coated panels or laminates where surface tearout is unacceptable.
- At 63mm overall length with a 10mm diameter, this bit is sized to fit tightly spaced spindle arrays on CNC boring centers and panel processing equipment, making it a practical drop-in choice for standard 32mm system cabinet layouts.

Frequently Asked Questions
What machines is the M10 threaded shank compatible with?
The M10 threaded shank on this dowel drill is designed for direct mounting to multi-spindle boring machines, CNC boring centers, and panel processing centers that accept M10 threaded tooling. This direct-mount design eliminates the need for an intermediate adapter, improving both accuracy and changeover speed.
What materials can this dowel drill bore through cleanly?
The carbide-tipped (HW) cutting construction and 2-spur geometry make this bit well suited for solid hardwood, softwood, chipboard, MDF, HDF, plywood, laminates, and coated panels. The dual-spur design shears the surface before the main cutting edges engage, which helps minimize tearout on finished or laminated surfaces.
What is the maximum boring depth this bit can reach?
This bit has a cutting height of 43mm, which defines the usable boring depth. The 63mm relative length is the overall length of the tool as mounted, and the 43mm cutting height is the maximum depth of cut available for dowel hole applications.
Is this bit right-hand or left-hand rotation, and why does that matter?
This bit is right-hand (RH) rotation, meaning it cuts when spinning clockwise when viewed from above - the standard direction for the vast majority of multi-spindle boring machine spindles and CNC boring centers. Confirming your machine's spindle rotation direction before installation ensures proper cutting action and prevents tool or machine damage. CMT also offers left-hand rotation variants for machines with reverse-rotation spindles.
