Product Description
CMT 310.065.11 Dowel Drill 6.5 x 27 x 57.5mm RH by CMT is a precision-engineered, right-hand rotation boring tool designed for clean, accurate blind hole drilling in furniture manufacturing, cabinet making, and panel processing operations. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this short-series dowel drill delivers consistent, flat-bottom bores for dowel joinery in chipboard, MDF, HDF, solid wood, plywood, laminates, and coated panels. The spiral flute section is coated with P.T.F.E. to resist pitch and adhesive buildup, keeping the tool running cleanly through production cycles. With a 6.5mm cutting diameter, a 27mm cutting height, and a parallel shank with driving flat and length-adjusting screw, this drill is a reliable choice for multi-spindle CNC boring machines, CNC boring centers, and panel processing equipment.
Key Features
- 2 HW precision-ground cutting edges (Z2) - tungsten carbide construction holds a sharp edge longer in abrasive engineered sheet materials, reducing regrind frequency and downtime in high-volume panel drilling.
- 2 negatively ground spurs (V2) - cleanly score the material perimeter ahead of the cutting edges, producing smooth bore walls and tear-out-free entry points on laminates and coated panel surfaces.
- P.T.F.E.-coated spiral flutes - the orange or black anti-stick coating prevents resin, pitch, and adhesive from binding to the flutes, maintaining chip evacuation efficiency and extending tool service life.
- Precision-balanced centre point - locates the drill accurately on the bore centre, eliminating wander at entry and ensuring repeatable hole positioning for tight-tolerance dowel connections.
- Parallel shank with driving flat and length-adjusting screw - provides a secure, non-slip fit in boring machine chucks and adapters, while the adjusting screw allows fine-tuning of boring depth without additional tooling changes.
- Super-strength steel body - the robust steel construction supports the HW cutting head under the lateral and axial forces common in multi-spindle CNC operations, maintaining concentricity over extended use.
- Right-hand (RH) rotation - compatible with the standard spindle direction of conventional boring machines and CNC boring centers, making direct installation straightforward without spindle direction changes.
- Short series at 57.5mm total length - the compact overall length minimizes overhang and vibration, contributing to cleaner holes and improved positional accuracy during panel processing.
Why This Product
- Dowel joinery demands a flat, clean-walled blind hole - the combination of negatively ground spurs and HW precision-ground cutting edges means this drill produces bore quality that requires no secondary clean-up, even in laminated or coated panels where tear-out is a common problem.
- Pitch and glue buildup on uncoated drills slows cut performance and shortens tool life in production environments - the P.T.F.E. spiral coating addresses this directly, keeping the flutes clear and reducing the frequency of tool changes on busy boring lines.
- The 10 x 27mm parallel shank with driving flat is sized for direct use in multi-spindle CNC boring machines and boring centers without adapter modifications, making this drill a practical drop-in solution for standard furniture panel drilling setups.
- At 6.5mm diameter with a 27mm cutting height, this dowel drill covers the most common dowel peg size used in flat-pack and cabinet carcass construction, making it a versatile everyday tool for furniture manufacturers and cabinet shops working across chipboard, MDF, hardwood, and plywood.

Frequently Asked Questions
What shank does this dowel drill use, and will it fit my boring machine?
This drill uses a 10 x 27mm parallel shank with a driving flat and a length-adjusting screw. This shank configuration is standard on multi-spindle CNC boring machines, CNC boring centers, and panel processing centers. The driving flat prevents rotation in the chuck, while the adjusting screw allows precise depth setting without additional tools.
What materials can this 6.5mm dowel drill be used on?
The HW (tungsten carbide) cutting head and negatively ground spurs make this drill suitable for chipboard, MDF, HDF, hardwood, softwood, plywood, laminates, and coated panels - the full range of materials typically encountered in furniture manufacturing and cabinet making applications.
What does the P.T.F.E. coating on the spiral flutes do?
The P.T.F.E. (orange or black) coating applied to the spiral portion of the drill prevents pitch, resin, and adhesive from sticking to the flutes during cutting. This keeps chip evacuation efficient, reduces heat buildup from friction, and extends the working life of the tool between sharpenings or replacements.
What is the difference between negatively ground spurs and standard spurs on a dowel drill?
Negatively ground spurs - as used on this CMT drill - are angled to score the material cleanly around the bore perimeter before the main cutting edges remove material. This geometry produces clean entry points with minimal tear-out or fiber lifting, which is especially important when drilling laminates, coated panels, and hardwoods where a clean surface finish at the hole edge is required for quality dowel joints.
