Product Description
CMT Two Flute Dowel Drill 6 x 44 x 77mm Left-Hand Rotation by CMT is a precision-engineered left-hand (LH) boring tool built for clean, flat-bottom blind holes in furniture panels, cabinet components, and engineered wood materials. With a 6mm cutting diameter, 44mm cutting height, and 77mm overall length, this long-series dowel drill handles deep blind hole drilling in thick substrates - delivering the accuracy and repeatability that professional CNC boring operations demand. Designed for left-hand spindle rotation, it pairs with multi-spindle boring machines, CNC boring centers, and panel processing equipment configured for LH tooling.
Key Features
- Tungsten Carbide (HW) Cutting Head - hard-metal construction delivers long service life and maintains sharp cutting geometry through high-volume production runs in chipboard, MDF, hardwood, and laminates.
- 2 Precision-Ground HW Cutting Edges (Z2) - dual carbide flutes produce a smooth, consistent bore wall on every pass, reducing the need for secondary finishing or cleanup.
- 2 Negatively Ground Spurs (V2) - the negative spur geometry scores the material cleanly at the perimeter of the bore before the flutes remove waste, preventing tearout and producing a flat-bottom hole with sharp, clean edges in coated panels and laminates.
- Precision Balanced Centre Point - keeps the drill on target from entry through full cutting depth, eliminating drift and ensuring accurate hole placement for tight-tolerance dowel joinery.
- PTFE-Coated Cutter Portion - the orange or black P.T.F.E. coating on the cutter body reduces friction and resists pitch and adhesive buildup, keeping the tool cutting freely without clogging and extending tool life between sharpenings.
- Super-Strength Steel Body - the steel shank and body absorb the stresses of repeated boring cycles without deflection, supporting consistent hole depth and position across large panel batches.
- Parallel Shank with Driving Flat and Length Adjusting Screw - the 10 x 30mm parallel shank seats securely in standard boring machine chucks, while the driving flat prevents rotation slip and the length adjusting screw enables precise depth setting at setup.
- Left-Hand (LH) Rotation - purpose-built for left-hand spindle positions on multi-spindle boring machines, ensuring correct chip evacuation direction and clean bore entry without requiring tool reversal.
Why This Product
- The 77mm overall length and 44mm cutting height make this drill capable of boring deep blind holes in thick panels - applications where a standard-length dowel drill would fall short of full depth without repositioning.
- The combination of negatively ground spurs and a precision-balanced centre point addresses the two most common failure points in panel boring: tearout at the hole perimeter and drill drift at entry - both of which compromise dowel joint quality.
- The PTFE coating on the cutter portion directly reduces downtime caused by pitch and glue buildup on the tool, keeping production moving without frequent cleaning interruptions during runs on coated or adhesive-laden panels.
- With a 10 x 30mm parallel shank featuring a driving flat and length adjusting screw, this drill integrates cleanly into standard multi-spindle CNC boring setups - no special adapters required for typical cabinet and furniture manufacturing configurations.

Frequently Asked Questions
What makes this a left-hand drill and when do I need one?
This drill is designed for left-hand (LH) rotation, meaning it cuts when the spindle turns counter-clockwise (when viewed from the chuck end). Multi-spindle boring machines used in furniture and cabinet panel processing use both right-hand and left-hand spindles simultaneously to drill rows of holes from a single pass. If your machine specifies LH tooling for a given spindle position, you must use an LH drill like this one to ensure correct chip evacuation direction and clean bore entry.
Why are negatively ground spurs important for panel boring?
Negatively ground spurs score the material at the outer edge of the bore before the main cutting edges remove material from the center. This sequencing prevents the drill from lifting or tearing the face veneer, laminate, or coating at the hole perimeter. The result is a flat-bottom blind hole with a clean, sharp edge - critical for tight-fitting dowel joints and visible panel faces in cabinet and furniture production.
What is the purpose of the PTFE coating on the cutter portion?
The P.T.F.E. coating applied to the cutter portion of this drill reduces friction between the cutting edges and the material being bored. In production environments where panels may carry adhesive residue or resinous pitch - common in chipboard, MDF, and coated panels - the non-stick properties of P.T.F.E. resist buildup on the tool body. This keeps the tool cutting freely for longer periods between cleanings or sharpenings, supporting higher throughput in continuous production runs.
Is this drill compatible with a standard boring machine chuck or does it require a special holder?
This drill uses a 10 x 30mm parallel shank with a driving flat and a length adjusting screw. The parallel shank seats in standard boring machine chucks typically found on multi-spindle CNC boring machines, CNC boring centers, and panel processing centers. The driving flat prevents the shank from rotating in the chuck under load, and the length adjusting screw allows you to set the exact drilling depth at setup without additional gauging tools.
