CMT 311.140.11 Dowel Drill - 14 x 35 x 70mm Right-Hand is a precision two-flute boring tool engineered for clean, accurate blind hole drilling in panels and solid wood. Built on a super-strength steel body with a tungsten carbide (HW) cutting head, this right-hand dowel drill delivers flat-bottomed holes and tear-free bore walls in demanding furniture manufacturing and cabinet making environments. The 14mm cutting diameter, 35mm cutting height, and 70mm overall length make it a reliable choice for dowel joint preparation, panel boring, and repetitive hole drilling on multi-spindle and CNC boring machinery.

Key Features

• HW (Tungsten Carbide) Cutting Head - hardwearing carbide material maintains sharp cutting edges over long production runs, reducing downtime and tool change frequency in high-volume panel processing.
• 2 Precision-Ground HW Cutting Edges - dual carbide edges produce consistent, flat-bottomed blind holes with accurate diameter control, critical for tight-fitting dowel connections.
• 2 Negatively Ground Spurs - the negative grind geometry scores the workpiece perimeter before the cutting edges advance, eliminating tearout and leaving clean entry points on laminates, coated panels, and veneered surfaces.
• P.T.F.E. Coated Spiral Flutes - the orange or black P.T.F.E. coating on the spiral portion prevents pitch and glue buildup, allowing chips to evacuate freely and keeping the tool cutting efficiently through chipboard, MDF, and solid wood.
• Precision Balanced Centre Point - the HW centre point self-locates accurately at the bore position, reducing drift and ensuring repeatable hole placement across multi-spindle boring operations.
• Parallel Shank with Driving Flat and Length Adjusting Screw - the 10 x 30mm shank design locks securely in compatible boring machine collets, and the length adjusting screw allows precise depth setting without additional tooling.
• Right-Hand Rotation - RH rotation is compatible with the majority of standard CNC boring centers and multi-spindle boring machines, ensuring broad machine compatibility without special adapters.
• Super-Strength Steel Body - the steel shank and spiral body resist flexing under lateral load, contributing to dimensional accuracy and extended service life in panel production environments.

Why This Product

• The combination of 2 negatively ground spurs and precision-ground carbide cutting edges makes this drill a direct solution for tearout problems on laminates, coated chipboard, and MDF - materials that are particularly prone to surface damage at the bore entry.
• At 70mm overall length with a 35mm cutting height, this long-series dowel drill reaches the boring depth needed for blind hole dowel joinery in standard panel thicknesses, while the balanced centre point keeps every hole on location across a full production shift.
• The P.T.F.E. spiral coating actively resists glue and resin adhesion, which is especially valuable when drilling pre-glued or resin-rich materials such as MDF and chipboard where buildup can quickly degrade cut quality.
• The 10 x 30mm parallel shank with driving flat and length adjusting screw fits directly into multi-spindle CNC boring machines and panel processing centers, delivering a ready-to-run setup without modification.
