Product Description
CMT Two Flute Dowel Drill 10 x 44 x 77mm RH by CMT is a precision-engineered carbide-tipped boring tool designed for clean, accurate blind hole drilling in furniture panels, cabinet components, and solid wood assemblies. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this right-hand rotating dowel drill produces flat-bottom bores ideal for dowel joinery, shelf pin holes, and panel-to-panel connections. The 44mm cutting height gives this long-series drill the reach needed for deep blind holes in thick substrates, while the PTFE coating on the cutter portion prevents pitch and glue buildup during production runs.
Key Features
- HW (Tungsten Carbide) Cutting Head with Precision Balanced Centre Point - delivers accurate hole positioning from first contact, reducing wander and misalignment in dowel boring applications.
- 2 HW Precision Ground Cutting Edges (Z2) - two carbide cutting edges provide balanced chip removal and consistent bore geometry, extending tool life between sharpenings compared to steel-only alternatives.
- 2 Negatively Ground Spurs (V2) - score the material perimeter ahead of the cutting edges, producing clean bore walls and sharp, chip-free entry holes with no tearout on laminates, coated panels, or veneered surfaces.
- PTFE Coating on Cutter Portion - the orange or black non-stick coating resists pitch and adhesive buildup, reducing heat and friction so the drill stays cleaner during continuous production use.
- Super-Strength Steel Body - the steel shank and body resist flex and deflection under the lateral loads common in multi-spindle boring machines and CNC boring centers.
- Parallel Shank with Driving Flat and Length Adjusting Screw - the 10 x 30mm shank seats securely in machine chucks and boring heads, and the length adjusting screw allows precise depth setting without additional tooling.
- 10mm Diameter x 44mm Cutting Height - sized for standard 10mm dowel bores, with a 44mm cutting length that accommodates deep blind holes in thick panels without repositioning.
- Right-Hand (RH) Rotation - matches the standard spindle direction of the vast majority of CNC boring centers and multi-spindle panel drilling machines, making this a direct drop-in for most production setups.
Why This Product
- The negatively ground spurs combined with the HW precision cutting edges make this drill a strong choice for laminated chipboard and coated panels where tearout at the hole entry is unacceptable in finished furniture production.
- The PTFE non-stick coating on the cutter portion reduces cleaning downtime in high-volume cabinet and panel processing operations where glue and pitch accumulation would otherwise slow production.
- At 77mm total length with a 44mm cutting height, this long-series dowel drill reaches deep blind holes in thick panel stacks without requiring a drill extension or machine repositioning, supporting efficient single-pass boring.
- The parallel shank with driving flat and integrated length adjusting screw simplifies tool changes and depth calibration in multi-spindle CNC boring machines, reducing setup time between jobs.

Frequently Asked Questions
What is the difference between the cutting height and the total length on this dowel drill?
The cutting height is 44mm, which is the usable fluted portion of the drill that removes material. The total length of 77mm includes both the cutting section and the 10 x 30mm parallel shank. When setting boring depth on a machine, reference the 44mm cutting height rather than the overall 77mm length.
What does "negatively ground spurs" mean and why does it matter for panel drilling?
Negatively ground spurs are sharpened at an inward angle so they score the surface fiber of the workpiece ahead of the main cutting edges. This scoring action severs the material cleanly at the perimeter of the hole before the cutters remove the core, which prevents splintering and tearout - particularly important when drilling laminated panels, coated chipboard, or veneered surfaces where a clean hole entry is required in finished furniture components.
What machines are compatible with this dowel drill?
This drill is designed for use in multi-spindle CNC boring machines, CNC boring centers, and panel processing centers that accept a 10 x 30mm parallel shank with driving flat. It can also be used in boring machines equipped with an appropriate adapter or chuck that accepts this shank size. The right-hand rotation matches the standard spindle direction of these machine types.
What does the PTFE coating on the cutter do during use?
The orange or black PTFE coating applied to the cutter portion of this dowel drill acts as a non-stick layer that resists the accumulation of pitch, resin, and adhesive residue that builds up during production drilling. Keeping the flutes cleaner during operation reduces heat generation and friction, which helps maintain cutting edge sharpness and bore quality over longer production intervals.
