Product Description
CMT Dowel Drill with Countersink - 10x15x57mm, 10x25mm Shank, Right-Hand Rotation by CMT is a precision-engineered boring tool designed to drill and countersink in a single pass on multi-spindle and CNC boring machines. Built around a tungsten carbide (HW) cutting head bonded to a super-strength steel body, this right-hand spiral dowel drill delivers consistently clean, flat-bottom holes with a recessed countersink - making it the right choice for panel joinery, connector seating, and high-volume furniture production. The PTFE-coated spiral flutes resist pitch and adhesive buildup, keeping the tool running efficiently through chipboard, MDF, hardwood, plywood, and coated panels alike.
Key Features
- HW (Tungsten Carbide) Cutting Head: bonded to a super-strength steel body - delivers long-lasting edge retention and reliable performance across hardwood, softwood, MDF, and engineered panel materials without frequent resharpening.
- Integrated Countersink Design: drills and countersinks in one machine pass - eliminates the need for a secondary operation, saving cycle time and reducing setup complexity in panel processing.
- PTFE-Coated Spiral Flutes: orange or black PTFE coating on the spiral portion resists pitch and glue buildup - extends tool life and keeps chip evacuation smooth during extended production runs.
- 2 Precision-Ground Cutting Edges (Z2): balanced cutting geometry produces clean bore walls and accurate hole geometry - reduces tear-out on coated and laminated panels.
- 2 Ground Spurs (V2): precision-ground spurs score the material perimeter before the main cutters engage - promotes clean entry holes with minimal surface chipping on laminates and coated panels.
- Precision Balanced Centre Point: keeps the drill accurately located at the start of each bore - prevents walking on flat panel surfaces and ensures repeatable hole positioning across multi-spindle setups.
- Parallel Shank with Driving Flat and Length Adjusting Screw: 10x25mm parallel shank provides secure, stable tool holding in boring machine chucks - the driving flat prevents slippage and the adjusting screw allows precise depth setting.
- Right-Hand (RH) Rotation: compatible with standard right-hand boring machine spindles - fits directly into conventional CNC boring centers and multi-spindle machines without adapter modification.
- 2 Spiral Flutes: dual-flute geometry balances chip load and evacuation - maintains smooth cutting action and reduces heat buildup during continuous drilling cycles.
Why This Product
- One-Pass Drilling and Countersinking: the integrated countersink eliminates a separate machining step, directly reducing cycle time on panel processing lines and boring centers - a practical advantage when running high volumes of cabinet or furniture components.
- Built for Production Boring Machines: the 10x25mm parallel shank with driving flat and length adjusting screw is engineered for direct, secure mounting in multi-spindle CNC boring machines and boring centers - no adapter workarounds required for standard 10mm spindles.
- PTFE Coating Reduces Downtime: the pitch- and glue-resistant PTFE spiral coating means fewer stoppages to clean the tool during runs involving adhesive-coated or resin-heavy materials like MDF and chipboard.
- Clean Results on Coated and Laminated Surfaces: the combination of precision-ground spurs and a balanced carbide centre point means countersunk bolt head and connector recesses come out clean-edged - reducing the sanding or touch-up work needed before assembly.

Frequently Asked Questions
What is the difference between this dowel drill and a standard dowel drill without a countersink?
This drill includes an integrated countersink feature that creates a clean recessed shoulder around the bore hole in the same machine pass. A standard dowel drill produces only a flat-bottom cylindrical hole. The countersink on this tool is intended to seat bolt heads or panel connectors flush with or below the surface, removing the need for a separate countersinking operation.
What type of machine is this dowel drill designed for?
This drill is designed for use in multi-spindle CNC boring machines, CNC boring centers, panel processing centers, and boring machines equipped with an adapter or chuck that accepts a 10x25mm parallel shank. The driving flat on the shank and the length adjusting screw ensure secure, repeatable tool positioning in production boring setups.
What does the PTFE coating on the spiral flutes do?
The PTFE coating on the spiral portion of the drill resists the buildup of pitch and glue on the flute surfaces. This is especially useful when processing resin-rich materials like MDF, chipboard, or adhesive-coated panels, where residue accumulation can reduce chip evacuation efficiency and shorten tool service life. The coating helps keep the flutes clear and the tool running smoothly during extended production cycles.
Is this tool suitable for drilling laminates and coated panels?
Yes. The 2 precision-ground spurs score the material perimeter before the main cutting edges engage, which suppresses surface chipping at the bore entry. Combined with the precision balanced carbide centre point and the 2-flute cutting geometry, this drill is well-suited for use on laminates, coated panels, and other surface-sensitive board materials where clean entry holes are required.
