Product Description
CMT Dowel Drill 10 x 27 x 57.5mm RH is a precision-engineered, carbide-tipped boring tool built for clean, accurate blind-hole drilling in furniture manufacturing, cabinet making, and panel processing applications. Designed for right-hand rotation and featuring two tungsten carbide (HW) cutting edges with negatively ground spurs, this 10mm dowel drill delivers flat-bottomed holes with smooth, tear-free walls in chipboard, MDF, hardwood, softwood, plywood, laminates, and coated panels. The super-strength steel body with PTFE-coated spiral flutes keeps pitch and adhesive from building up, making it a reliable choice for high-volume dowel joinery and panel boring operations on CNC and multi-spindle machines.
Key Features
- 2 HW precision-ground cutting edges (Z2) - tungsten carbide tips maintain a sharp, durable edge through demanding production runs, reducing downtime and regrinding frequency.
- 2 negatively ground spurs (V2) - score the material perimeter before the main cutting edges engage, producing clean bore walls and flat-bottom holes with no tearout or rough edges in laminates and coated panels.
- 2 spiral flutes with PTFE coating - the orange or black PTFE finish on the spiral portion repels pitch, resin, and adhesive buildup, extending tool life and keeping cuts clean without constant cleaning intervals.
- Super-strength steel body - provides the rigidity needed to resist deflection at high spindle speeds, supporting consistent hole placement across large panel runs.
- Precision balanced centre point - starts on-center immediately, eliminating wander and ensuring accurate dowel hole positioning for tight-fitting joints.
- Parallel shank with driving flat and length adjusting screw - secures firmly in multi-spindle boring heads and CNC boring machine chucks, with easy depth adjustment without removing the bit.
- Right-hand (RH) rotation - compatible with standard CNC boring centers, panel processing centers, and multi-spindle machines configured for right-hand tooling.
Why This Product
- The combination of negatively ground spurs and carbide cutting edges produces flat-bottomed blind holes with clean edges - critical for dowel connections in furniture and cabinet panels where surface finish and joint accuracy matter.
- PTFE-coated spiral flutes reduce pitch and glue adhesion during production, meaning less frequent tool cleaning and more consistent performance across long boring sessions in chipboard and MDF.
- The parallel shank with driving flat and length adjusting screw makes this bit straightforward to install and set in multi-spindle CNC boring heads, supporting fast changeover in production environments.
- At 57.5mm overall length with a 27mm cutting height, this short-series dowel drill fits the geometry of standard boring machine spindle configurations while providing sufficient cutting depth for typical dowel joint applications.

Frequently Asked Questions
What materials can this dowel drill be used on?
This dowel drill is suitable for blind-hole boring in chipboard, MDF, HDF, hardwood, softwood, plywood, laminates, and coated panels. The negatively ground spurs and carbide cutting edges help maintain clean hole edges across all of these materials, including surfaces with decorative or protective coatings.
What is the purpose of the PTFE coating on the spiral flutes?
The PTFE coating on the spiral portion of the drill prevents pitch, resin, and adhesive from sticking to the flutes during boring. This reduces buildup that can cause friction, slow chip evacuation, or affect hole quality - helping the tool maintain consistent performance over longer production runs without frequent cleaning.
What type of machine is this dowel drill designed for?
This bit is designed for use in multi-spindle CNC boring machines, CNC boring centers, and panel processing centers. It can also be used in boring machines equipped with a compatible adapter or chuck. The parallel shank with driving flat and length adjusting screw ensures secure, adjustable seating in these machine types.
What does "negatively ground spurs" mean and why does it matter?
Negatively ground spurs are spurs whose cutting angle is oriented to score the material perimeter before the main carbide edges remove material. This sequencing prevents the material surface - especially in laminates and coated panels - from chipping or tearing at the hole edge, resulting in a clean, smooth-walled blind hole suitable for tight-fitting dowel joints.
