CMT Dowel Drill with Countersink - 10x20x70mm, 10x33mm Shank, Right-Hand Rotation is a precision-engineered boring tool from CMT designed to drill and countersink in a single pass, eliminating the need for a separate countersinking step when processing panel goods, furniture components, and cabinet parts. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this right-hand rotating drill is purpose-built for use in multi-spindle CNC boring machines, boring centers, and panel processing equipment. The PTFE-coated spiral flutes resist pitch and adhesive buildup during repeated production runs, keeping the tool performing cleanly across high-volume applications in chipboard, MDF, hardwood, softwood, plywood, and coated panel materials.

Key Features

• HW (Tungsten Carbide) Cutting Head on Super-Strength Steel Body - delivers long-lasting edge retention and resistance to wear during continuous boring operations, reducing replacement frequency in production environments.
• Integrated Countersink Geometry - combines drilling and countersinking into one operation, saving cycle time and minimizing tool changes when creating recesses for bolt heads or panel connectors.
• 2 Precision-Ground Cutting Edges (Z2) - balanced cutting action produces consistent, repeatable hole quality with minimal vibration across each bore.
• 2 Ground Spurs with Negative Sharpening (V2) - negatively ground spurs score the material perimeter ahead of the main cutting edges, producing clean bore walls and sharp, tear-out-free entry points in veneered, laminated, and coated panels.
• 2 Spiral Flutes with PTFE (Orange or Black) Coating - the non-stick PTFE coating prevents pitch and glue from bonding to the spiral, maintaining consistent chip evacuation and extending tool service life without frequent cleaning.
• Precision-Balanced Centre Point - promotes accurate hole location and reduces walking at the start of each bore, which is especially critical in CNC multi-spindle applications where positional tolerance is tight.
• Parallel Shank with Driving Flat and Length-Adjusting Screw (10x33mm) - the driving flat ensures positive torque transfer without slipping, while the length-adjusting screw allows fine depth setting directly in the machine spindle for consistent countersink depth across every workpiece.
• Right-Hand (RH) Rotation - matches standard CNC boring spindle configurations, ensuring compatibility with conventional machine setups without adapter modifications.

Why This Product

• Combining a dowel bore and countersink recess into a single-pass operation reduces cycle time in panel processing and cabinet manufacturing - no secondary tool or additional spindle position required for connector recessing.
• The negatively ground spurs and carbide cutting head work together to produce clean, chip-free entry on coated panels, laminates, and hardwood faces where surface quality is critical to finished appearance.
• PTFE spiral coating actively resists adhesive and resin buildup common in MDF and chipboard machining, keeping the tool cutting cleanly through extended production runs without frequent stops for cleaning.
• The 10x33mm parallel shank with driving flat and length-adjusting screw gives machine operators direct control over countersink depth, ensuring consistent bolt-head recesses or connector pockets across every panel in a batch.
