CMT 314.047.11 Dowel Drill for Through Holes - 3/16" x 35 x 70mm RH is a precision-engineered, 2-flute through-hole dowel drill built for clean, accurate boring in panel processing, furniture manufacturing, and dowel joinery applications. Designed for use in multi-spindle CNC boring machines, boring centers, and panel processing equipment, this drill delivers consistent through-hole results in chipboard, MDF, hardwood, softwood, plywood, laminates, and coated panels without blowout on exit. The tungsten carbide (HW) cutting head, right-hand rotation, and parallel shank with driving flat make it a reliable choice for high-volume cabinet and furniture production environments.

Key Features

• Hardwood (HW) carbide cutting head with precision balanced centre point - delivers accurate hole placement and clean entry, reducing the need for rework on finished panels.
• 2 precision-ground cutting edges (Z2) - produce smooth, consistent bore walls in every pass, ensuring tight dowel fit and strong joinery connections.
• 2 spiral flutes with PTFE coating (orange or black) - resist pitch and adhesive buildup during repeated cuts, extending tool service life and maintaining cutting performance over time.
• Super-strength steel body - provides the structural rigidity needed to maintain dimensional accuracy during high-cycle boring operations in production environments.
• Parallel shank (10 x 26mm) with driving flat and length adjusting screw - ensures secure, repeatable tool registration in multi-spindle and CNC boring machine chucks, minimizing runout.
• Right-hand rotation (RH) - compatible with standard boring machine spindles, making integration into existing setups straightforward.
• 35mm cutting height on a 70mm overall length body - optimized for through-hole drilling in panels, providing the depth needed for full panel penetration without excessive overhang.

Why This Product

• The HW carbide head paired with a precision balanced centre point keeps holes on-location in production runs, which matters when boring for dowel connections where misalignment causes assembly failures.
• The PTFE-coated spiral flutes actively resist pitch and glue accumulation, so the drill stays cutting cleanly between tool changes - reducing downtime in high-volume panel and furniture manufacturing operations.
• The 10 x 26mm parallel shank with driving flat and length adjusting screw provides the positive tool engagement that multi-spindle CNC boring machines require for repeatable, accurate hole positioning across entire panel surfaces.
• With a 3/16" diameter and 35mm cutting height, this drill is purpose-built for standard through-hole dowel boring in panels, eliminating the compromises that come from using a general-purpose drill in a dedicated dowel boring application.
