CMT Four Flute Dowel Drill - 5 x 65 x 105mm Right Hand by CMT is a precision-engineered boring tool built for deep blind hole drilling in furniture manufacturing, cabinet making, and industrial panel processing. Designed for use on multi-spindle CNC boring centers and large panel processing machines, this extra-long dowel drill delivers clean, flat-bottom holes in solid wood, chipboard, MDF, HDF, plywood, laminates, and coated panels. The 105mm total length and 65mm cutting height make it well-suited for applications requiring greater boring depth than standard-length tools can achieve. With right-hand rotation, a 10x30mm parallel shank with driving flat, and a tungsten carbide (HW) cutting head, this tool is a dependable choice for high-volume dowel joinery and panel drilling operations.

Key Features

• Tungsten Carbide (HW) Cutting Head with 2 Precision Ground Cutting Edges (Z2) - carbide construction maintains sharp cutting geometry through extended production runs, reducing downtime from frequent tool changes.
• 2 Negatively Ground Spurs (V2) - the negative grind geometry scores the material cleanly before the cutters remove waste, producing bore walls and flat-bottom holes free of tearout and rough edges - critical for visible or glued dowel joints.
• 4 Spiral Flutes - four flutes evacuate chips efficiently during deep blind hole drilling, reducing heat buildup and keeping the bore clean for consistent hole quality throughout long production cycles.
• PTFE Coating on the Cutter Portion - the black or orange PTFE coating on the spiral prevents pitch and adhesive buildup, extending tool life and maintaining smooth chip flow during operations involving glued panels or resin-rich materials.
• Precision Balanced Centre Point - the HW centre point ensures accurate positioning at hole entry, reducing drift and contributing to tight dowel alignment across multi-hole boring patterns.
• Parallel Shank with Driving Flat and Length Adjusting Feature - the 10x30mm shank is compatible with standard boring machine chucks and adapters, and the driving flat prevents slippage under load while the length adjustment capability allows precise setting of boring depth.
• Super-Strength Steel Body - the steel shank and body resist deflection under the lateral forces generated during CNC boring, supporting dimensional consistency hole after hole.
• Extra-Long 105mm Total Length with 65mm Cutting Height - the extended geometry allows drilling deep blind holes that would be unreachable with standard-length dowel drills, expanding the range of joint configurations possible on panel furniture and cabinet carcasses.

Why This Product

• The 65mm cutting height paired with the 105mm overall length addresses the specific need for deep blind dowel holes in thick panel assemblies and structural furniture joints - applications where standard-length dowel drills fall short.
• The combination of 2 precision ground carbide cutting edges and 2 negatively ground spurs means both chip removal and perimeter scoring happen simultaneously, giving you clean entry and exit conditions in laminated and coated panels where surface tearout is not acceptable.
• The PTFE-coated spiral actively resists pitch and glue adhesion, making this drill a practical choice for operations involving pre-glued panels, resin-rich composites, or high-volume runs where residue accumulation would otherwise degrade hole quality over time.
• Right-hand rotation and a 10x30mm parallel shank with driving flat make this drill directly compatible with the tooling interfaces found on multi-spindle CNC boring centers and panel processing centers, allowing drop-in integration without adapters in most standard setups.
