CMT 314.095.12 Dowel Drill for Through Holes - 3/8" Diameter, 2 Flute, Left-Hand Rotation by CMT is a precision carbide-tipped boring tool engineered for drilling clean, accurate through holes in panel-based materials used in furniture manufacturing and cabinetry. With a 35mm cutting height and 70mm total length, this left-hand (LH) rotating dowel drill is designed for multi-spindle boring machines and CNC boring centers where consistent dowel hole placement is critical. The 10x26mm parallel shank with driving flat and length adjusting screw ensures secure, repeatable tool positioning on every run.

Key Features

• HW (Tungsten Carbide) Cutting Head with Precision Balanced Centre Point - delivers accurate hole entry and minimizes wandering at the start of the bore, resulting in precisely positioned dowel holes every cycle.
• 2 Precision Ground Cutting Edges (Z2) - dual cutting edges provide a balanced cutting action that reduces vibration and produces smooth, consistent bore walls, reducing the need for secondary cleanup.
• 2 Spiral Flutes - efficiently evacuate chips and debris from the bore during through-hole drilling, helping prevent clogging and maintaining cut quality throughout production runs.
• PTFE-Coated Spiral Portion (Orange or Black) - the polytetrafluoroethylene coating on the flute area resists pitch and adhesive buildup, extending tool life and keeping the drill running cleanly between sharpenings.
• Super-Strength Steel Body - the robust steel construction withstands the demands of repeated high-cycle boring operations, maintaining dimensional stability under continuous use.
• Parallel Shank with Driving Flat and Length Adjusting Screw - allows precise depth setting and secure engagement in multi-spindle boring heads, reducing slippage and ensuring repeatable hole depth across all spindles.
• Left-Hand (LH) Rotation - correctly matched to left-hand spindle positions on multi-spindle boring machines, ensuring proper chip ejection direction and clean hole exit on through-hole applications.
• Sharpening Specification: Through Holes 60 - defined resharpening parameters allow the tool to be professionally resharpened and returned to service, lowering the long-term cost per hole.

Why This Product

• Through-hole geometry with a 35mm cutting height accommodates panel thicknesses typical in furniture and cabinet panel processing, allowing clean hole exit without blowout on the back face.
• The HW carbide head combined with PTFE-coated spiral flutes makes this drill well suited for abrasive sheet materials including chipboard, MDF, and coated panels where edge quality directly affects assembly fit.
• Left-hand rotation designation makes this the correct choice for LH spindle positions on multi-spindle boring machines, eliminating the guesswork of spindle-side matching during machine setup.
• The length adjusting screw on the parallel shank enables consistent depth calibration across multiple spindles simultaneously, reducing setup time and improving hole-to-hole consistency on production lines.
