CMT Dowel Drill 11 x 35 x 70mm Right-Hand is a precision-engineered, two-flute boring tool built for clean, accurate blind-hole drilling in furniture panels, cabinetry components, and solid wood workpieces. Designed for right-hand rotation and fitted with a 10 x 30mm parallel shank with a driving flat and length-adjusting screw, this carbide-tipped (HW) drill integrates directly into multi-spindle CNC boring machines and panel processing centers. The 11mm cutting diameter and 35mm cutting height make it well-suited for standard dowel-joint applications where consistent bore depth and smooth hole walls are critical to assembly quality.

Key Features

• Hardmetal (HW) cutting head with precision-balanced centre point - delivers accurate hole positioning on entry, reducing workpiece movement and eliminating wandering on the bore axis, which is essential when drilling panels on high-speed boring centers.
• 2 precision-ground HW cutting edges - tungsten carbide edges maintain sharpness longer than standard high-speed steel, reducing the frequency of tool changes and lowering per-hole production cost over long production runs.
• 2 negatively ground spurs - score the material fibres cleanly ahead of the cutting edges, producing flat-bottom blind holes with crisp, tear-out-free walls in chipboard, MDF, solid wood, laminates, and coated panels.
• 2 spiral flutes with PTFE coating - the orange or black P.T.F.E. surface on the spiral portion prevents pitch and adhesive buildup during boring, keeping the flutes clear and maintaining consistent chip evacuation throughout the workday.
• Super-strength steel body - provides the rigidity needed to resist deflection at spindle speeds typical of multi-row boring heads, helping maintain bore-to-bore spacing accuracy across an entire panel.
• Parallel shank with driving flat and length-adjusting screw - enables secure, repeatable seating in standard boring machine spindles and allows straightforward depth setting without additional tooling.
• Right-hand rotation (RH) - matches the standard spindle direction of the vast majority of CNC boring centers and multi-spindle boring machines, making this drill a direct-fit replacement for worn tooling.

Why This Product

• The negatively ground spurs combined with precision-ground HW cutting edges work together to produce clean bore walls and flat hole bottoms - a critical requirement in dowel-connection joinery where surface finish inside the bore affects glue adhesion and joint strength.
• At 70mm total length with a 35mm cutting height, this long-series dowel drill reaches the boring depth needed for deeper blind holes in thicker panel stock without requiring an extended adapter, simplifying spindle setup on CNC boring centers.
• The PTFE-coated spiral addresses one of the most common causes of premature dowel drill failure - pitch and glue buildup in the flutes - keeping the tool running efficiently across extended production shifts in furniture and cabinet manufacturing environments.
• The 10 x 30mm parallel shank with driving flat is the industry-standard interface for multi-spindle boring machines, making this drill compatible with a wide range of panel processing equipment without modification.
