Product Description
CMT 309.095.11 Dowel Drill - 3/8" Diameter, 2 Spurs, 43mm Cutting Height, 70mm Overall Length, Right-Hand Rotation is a precision-engineered boring tool built for high-volume furniture manufacturing, cabinet making, and panel processing. Designed for consistent, clean blind holes in solid wood, chipboard, MDF, and laminates, this CMT dowel drill delivers the accuracy and durability demanded by multi-spindle CNC boring machines and panel processing centers. The 70mm overall length accommodates deeper drilling applications in thicker panel stock where a standard-length drill would fall short.
Key Features
- Tungsten Carbide (HW) Cutting Head - hard-wearing carbide material maintains a sharp edge through repeated drilling cycles in chipboard, MDF, and coated panels, reducing downtime for tool changes.
- Precision-Balanced Centre Point - the HW centre point self-locates accurately on the workpiece surface, ensuring each hole is drilled on target without walking or drift, which is critical for dowel-joinery alignment in furniture assembly.
- 2 Precision-Ground Cutting Edges (Z2) - dual carbide cutting edges shear material cleanly at the base of the hole, producing a flat-bottomed bore suitable for dowel insertion without additional clean-up passes.
- 2 Negatively Ground Spurs (V2) - the negatively ground spur geometry scores the perimeter of the hole before the cutting edges remove material, preventing tearout and delivering clean, chip-free bore walls in laminates and coated panels.
- 4 Spiral Flutes - four flutes evacuate chips and dust efficiently away from the cutting zone, keeping the bore clear and reducing heat buildup during continuous production drilling.
- PTFE Coating on Cutter Portion - the black or orange PTFE coating on the spiral portion resists pitch and adhesive buildup, extending tool life and maintaining smooth chip flow during panel drilling operations.
- Parallel Shank with Driving Flat and Length Adjusting Screw (10x20mm) - the standardized shank with driving flat transfers torque without slipping, while the length adjusting screw allows precise depth setting in multi-spindle boring heads for repeatable blind-hole depth across a production run.
- Right-Hand (RH) Rotation - compatible with the standard spindle rotation direction on multi-spindle CNC boring machines and boring centers, making this drill a direct drop-in for conventional panel processing setups.
- 70mm Overall Length - the extended body length provides sufficient clearance for drilling in thicker panels and accommodates adapter or chuck mounting on boring machines that require additional standoff.
Why This Product
- The combination of 2 negatively ground spurs and 2 precision carbide cutting edges means this drill produces tearout-free holes in laminates, coated panels, and MDF on the first pass - no secondary cleanup required, keeping production lines moving.
- The 43mm cutting height paired with a 70mm overall length makes this drill suitable for deeper blind holes in thicker panel stock where shorter dowel drills cannot reach full depth, eliminating the need for a different tool class in mixed-panel production.
- The PTFE-coated spiral resists pitch and glue accumulation that would otherwise degrade cut quality over time, meaning fewer interruptions for cleaning or tool replacement during high-volume cabinet and furniture manufacturing runs.
- The 10x20mm parallel shank with driving flat and length adjusting screw integrates directly into multi-spindle CNC boring heads and panel processing centers, enabling fast, precise depth setup without custom tooling or adapters.

Frequently Asked Questions
What is the difference between the negatively ground spurs and standard spurs on this dowel drill?
The 2 negatively ground spurs on the CMT 309.095.11 are configured to score the outer perimeter of the hole with a cutting angle that pulls the spur into the material in a controlled manner, minimizing chip breakout at the surface. This is especially important when drilling through laminates, coated panels, or veneered chipboard where a standard spur geometry would cause tearout at the entry point.
What machine shank interface does this dowel drill use, and how is drilling depth set?
This drill uses a 10x20mm parallel shank with a driving flat and a length adjusting screw. The driving flat ensures positive torque transfer without the shank spinning in the collet or chuck. The length adjusting screw allows the operator to set a precise drilling depth, which is critical for repeatable blind-hole depth across a full production run on multi-spindle boring machines and panel processing centers.
Why does this drill have 4 spiral flutes if it only has 2 cutting edges?
The 4 spiral flutes serve a chip evacuation function independent of the number of cutting edges. With 4 flutes channeling chips and dust out of the bore during drilling, the cutting zone stays clear and cool, reducing friction and preventing chip packing that could deflect the drill or damage the bore wall. This design is particularly beneficial during continuous production drilling in chipboard and MDF, where dust volume is high.
Is this dowel drill suitable for drilling through-holes as well as blind holes?
While this drill is engineered primarily for blind-hole dowel boring - as indicated by its flat-bottomed cutting geometry with precision-ground cutting edges and negatively ground spurs - the 43mm cutting height and 70mm overall length do allow it to be used in applications requiring deeper penetration in thicker panels. Its design is optimized for clean, flat-bottomed holes suited to dowel joinery rather than through-boring applications.
