Product Description
CMT 310.080.11 Dowel Drill 8 x 27 x 57.5mm RH is a precision-engineered, carbide-tipped boring tool built for accurate blind hole drilling in furniture panels, cabinet components, and engineered wood materials. Designed with 2 tungsten carbide (HW) cutting edges and 2 negatively ground spurs, this right-hand rotation drill produces clean, flat-bottomed holes ideal for dowel joinery, panel assembly, and cabinet making. The spiral portion carries a P.T.F.E. coating that prevents pitch and adhesive buildup, keeping the flutes clear during continuous production runs. A parallel shank with driving flat and a length-adjusting screw ensures repeatable, secure seating in multi-spindle CNC boring machines, boring centers, and panel processing equipment.
Key Features
- 2 HW (tungsten carbide) precision-ground cutting edges (Z2) - hard carbide material maintains a sharp edge through demanding production cycles in chipboard, MDF, hardwood, and laminates, reducing downtime from frequent tool changes.
- 2 negatively ground spurs (V2) - shear the wood fibers at the perimeter of the hole before the main cutters engage, producing clean bore walls and a flat-bottom hole with no tearout or rough edges - critical for tight-fitting dowel connections.
- 2 spiral flutes with P.T.F.E. coating - the non-stick coating on the spiral portion resists pitch and glue adhesion, extending tool life and maintaining consistent chip evacuation during high-volume panel drilling.
- Precision-balanced centre point - keeps the drill from wandering on entry, ensuring hole placement accuracy that is essential for furniture manufacturing and cabinet assembly tolerances.
- Super-strength steel body - provides rigidity and vibration resistance at production boring speeds, supporting the carbide head during repetitive drilling operations.
- Parallel shank with driving flat and length-adjusting screw (10 x 27mm) - allows secure, slip-free mounting and precise depth setting in multi-spindle boring heads, CNC boring centers, and adapted chuck systems.
- Right-hand rotation (RH) - matches the standard spindle direction of the vast majority of CNC boring machines and multi-spindle panel processing equipment, ensuring direct compatibility without adapters.
- Short-series overall length of 57.5mm - compact profile suits typical spindle spacing in multi-spindle boring machines, minimizing deflection and contributing to bore positional accuracy.
Why This Product
- The combination of negatively ground spurs and HW cutting edges delivers clean, chip-free entry and exit in coated panels, MDF, and chipboard - materials where tearout directly affects finished product quality in furniture and cabinet production.
- P.T.F.E. coating on the spiral flutes addresses one of the most common productivity problems in panel boring: adhesive and resin buildup that slows chip removal and shortens tool life, particularly in laminated and pre-glued board stock.
- The 10 x 27mm parallel shank with driving flat and length-adjusting screw is engineered for reliable seating in multi-spindle CNC boring machines and boring centers - no slippage, consistent depth, and repeatable results hole after hole.
- An 8mm cutting diameter with a 27mm cutting height covers the dimensional requirements of standard metric dowel connections, making this drill a practical fit for furniture manufacturing, cabinet making, and panel processing workflows that rely on 8mm dowel joinery.

Frequently Asked Questions
What machines is this dowel drill compatible with?
This drill is designed for use in multi-spindle CNC boring machines, CNC boring centers, panel processing centers, and boring machines fitted with an adapter or chuck. The 10 x 27mm parallel shank with driving flat and length-adjusting screw is the standard configuration for these machine types.
What is the purpose of the P.T.F.E. coating on the spiral?
The P.T.F.E. coating on the spiral portion of the drill prevents pitch and adhesive buildup on the flutes. This is especially valuable when boring laminated panels, pre-glued boards, and resin-rich materials, where residue accumulation can restrict chip flow and accelerate tool wear.
Why are negatively ground spurs important for panel boring?
Negatively ground spurs score the perimeter of the hole before the carbide cutting edges remove material. This shearing action prevents the wood fibers and surface laminates from being pulled or torn rather than cleanly cut, resulting in smooth bore walls and flat-bottom holes - a requirement for accurate, tight-fitting dowel joints in furniture and cabinet work.
Is this drill suitable for drilling through-holes as well as blind holes?
This drill is specifically engineered for blind hole drilling - the geometry of the negatively ground spurs, the precision-balanced centre point, and the flat-bottom cutting profile are all optimized for creating stopped holes to precise depths for dowel joinery, not through-hole applications.
