CMT 362.050.12 Two Flute Dowel Drill - 5 x 44 x 77mm Left-Hand Rotation is a precision-engineered left-hand boring tool from CMT, designed for accurate blind hole drilling in furniture panels, cabinet components, and engineered wood assemblies. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this 5mm dowel drill delivers flat-bottom holes with clean bore walls in chipboard, MDF, hardwood, softwood, plywood, laminates, and coated panels. Its 44mm cutting height and 77mm total length make it well suited for deep blind holes in thick panels where a standard-length drill falls short.

Key Features

• HW (Tungsten Carbide) Cutting Head - provides long-lasting edge retention when boring abrasive materials like MDF, chipboard, and laminates, reducing resharpening frequency and downtime.
• 2 Precision-Ground HW Cutting Edges (Z2) - dual carbide cutting edges distribute cutting load evenly, promoting a smooth, accurate bore and consistent hole diameter across repeated operations.
• 2 Negatively Ground Spurs (V2) - score the material fiber ahead of the cutting edges, preventing tearout at the hole perimeter and delivering clean entry in coated and laminated panels.
• PTFE Coating on Cutter Portion - the orange or black non-stick coating resists pitch and adhesive buildup on the flutes, keeping the tool running cleanly and reducing heat-related wear during high-cycle production boring.
• Precision-Balanced Centre Point - ensures accurate hole placement and prevents bit walk at the start of each bore, critical for dowel joint alignment in furniture and cabinet assembly.
• Parallel Shank with Driving Flat and Length-Adjusting Screw - the 10x28mm shank seats securely in multi-spindle boring machines and CNC boring centers, with the adjusting screw allowing precise depth setting without additional tooling.
• Left-Hand (LH) Rotation - engineered specifically for left-hand spindle positions on multi-spindle boring machines, ensuring correct cutting geometry and clean chip evacuation on the appropriate machine station.
• Super-Strength Steel Body - resists deflection and vibration during deep blind hole drilling, supporting dimensional consistency in high-volume panel processing.

Why This Product

• The 77mm total length with 44mm cutting height addresses deep blind hole requirements in thick panels where shorter dowel drills cannot reach the required depth - making this the correct choice for heavy panel furniture and cabinet carcass construction.
• The combination of negatively ground spurs and a carbide cutting head makes this drill suitable for both raw and pre-finished or coated panels, protecting surface quality on visible faces without a secondary cleanup step.
• Left-hand rotation is built into the tool geometry rather than being an adapter solution, ensuring the cutting edges and spurs are correctly oriented for LH spindle stations on multi-spindle CNC boring machines and panel processing centers.
• The PTFE non-stick cutter coating is especially valuable in high-production environments using MDF or adhesive-treated components, where resin and pitch accumulation on standard drills causes frequent interruptions for cleaning.
