CMT 314.095.11 Dowel Drill for Through Holes - 3/8" Diameter, 2 Flute, 70mm Length, Right-Hand Rotation by CMT is a precision-engineered boring tool built for drilling clean through-holes for dowel joinery in panel processing and furniture manufacturing. Designed for use in multi-spindle boring machines and CNC boring centers, this 3/8 in. drill combines a tungsten carbide (HW) cutting head with a PTFE-coated spiral and a parallel shank to deliver accurate, blowout-free holes through solid wood, chipboard, MDF, and laminated panels alike.

Key Features

• Hard metal (HW) carbide cutting head with precision-balanced centre point - delivers accurate entry and consistent hole positioning, reducing wandering and off-center starts even in high-production boring runs.
• 2 precision-ground cutting edges (Z2) - two finely honed edges work together to produce smooth, clean bore walls with minimal fiber tearout on both entry and exit faces of the panel.
• 2 spiral flutes with orange or black PTFE coating - the non-stick PTFE surface prevents pitch, resin, and adhesive buildup on the spiral, keeping the bit running cooler and extending tool life between sharpenings.
• Super-strength steel body - the robust steel construction resists flex and deflection under load, maintaining dimensional accuracy across repeated through-hole drilling cycles.
• Parallel shank (10 x 26mm) with driving flat and length adjusting screw - positive drive engagement and easy depth adjustment allow the bit to be set precisely in boring machine chucks or adapters without slipping.
• Through-hole geometry optimized for 60 deg. sharpening - the cutting geometry channels chips efficiently out of the hole, preventing clogging and enabling clean exit cuts that protect panel surfaces from blowout.
• Right-hand (RH) rotation - matches the standard spindle direction of multi-spindle boring machines and CNC boring centers, ensuring correct engagement without needing special setup.

Why This Product

• Engineered specifically for through-hole dowel work - unlike general-purpose twist drills, this bit is designed from the ground up for the exact bore depths and exit quality required in dowel joint production, reducing rework and rejected panels.
• PTFE spiral coating means less downtime for cleaning - in high-volume furniture and panel processing operations, pitch and adhesive buildup is a leading cause of premature bit failure; the non-stick coating keeps the tool productive longer between maintenance intervals.
• 35mm cutting height in a compact 70mm overall length - the proportional cutting-to-shank length ratio balances deep-reach boring capability with stability in the machine spindle, making it well-suited for panels up to 35mm of engagement depth.
• Precision-balanced carbide centre point and ground cutting edges - consistent hole-to-hole accuracy is critical in furniture assembly where dowels must align across multiple components; the balanced geometry supports repeatable results at production speeds.
