The CMT 307.095.12 Dowel Drill 3/8" 2 x 40 x 67mm Left-Hand is a precision-engineered boring tool built for accurate blind hole drilling in furniture manufacturing, cabinet making, and panel processing applications. Featuring a tungsten carbide (HW) cutting head mounted on a super-strength steel body, this left-hand rotation dowel drill delivers clean, flat-bottomed holes with minimal tearout - making it a dependable choice for dowel joinery in solid wood, chipboard, MDF, and coated panels. With 2 precision-ground cutting edges and 2 negatively ground spurs, this drill produces consistently smooth bore walls that seat dowel connections cleanly and securely.

Key Features

• HW (Tungsten Carbide) Cutting Head on Super-Strength Steel Body - delivers long-lasting edge retention and durability under the demands of high-cycle panel boring operations, reducing the frequency of tool changes.
• 2 Precision-Ground HW Cutting Edges (Z2) - provide accurate, consistent material removal with each pass, producing flat-bottomed holes suited to tight-tolerance dowel assembly.
• 2 Negatively Ground Spurs (V2) - score the material cleanly before the cutting edges engage, preventing surface tearout and producing crisp, clean hole entry points in laminates and coated panels.
• Precision Balanced Centre Point - ensures the drill seats accurately on the workpiece without wandering, improving hole placement accuracy in multi-hole boring patterns.
• Left-Hand (LH) Rotation - designed specifically for left-hand spindle positions on multi-spindle boring machines and CNC boring centers, ensuring correct chip evacuation and cutting direction.
• 8 x 20mm Shank - fits standard boring machine chucks and adapters used in panel processing equipment, providing secure tool holding and minimal runout.
• 40mm Cutting Height with 67mm Total Length - the medium-length body provides sufficient boring depth for through-panel dowel applications while remaining compatible with typical spindle clearances.

Why This Product

• The 3/8" diameter with a 40mm cutting height makes this drill well-suited for blind dowel holes in furniture panels and cabinet carcasses where consistent depth and bore quality directly affect assembly fit and finish.
• The combination of negatively ground spurs and HW precision-ground cutting edges addresses one of the most common boring challenges - edge tearout on laminates and coated panels - by scoring material boundaries before cutting begins.
• Left-hand rotation matches the spindle configuration of the left-side boring units found on multi-spindle CNC boring machines and panel processing centers, making this a purpose-built replacement or expansion tool rather than a workaround adaptation.
• The precision balanced centre point reduces drill walk at the start of the bore, which is critical in multi-hole boring patterns where hole spacing accuracy affects dowel alignment across an entire panel assembly.
