CMT 307.090.12 Dowel Drill - 9 x 40 x 67mm Left-Hand Rotation is a precision-engineered carbide-tipped boring tool from CMT, purpose-built for clean, accurate blind hole drilling in solid wood, chipboard, MDF, laminates, and coated panels. Featuring a left-hand (LH) rotation design, this 9mm dowel drill is a reliable choice for furniture manufacturing, cabinet making, and panel processing applications where consistent bore quality and flat-bottomed holes are essential for tight-fitting dowel joints.

Key Features

• HW (Carbide) Head on Super-Strength Steel Body - the tungsten carbide cutting head bonded to a hardened steel shank delivers long service life even under continuous production boring conditions, reducing replacement frequency and downtime.
• Precision Balanced Centre Point - ensures the drill enters the workpiece on-center every time, producing accurately located holes that align precisely for dowel assembly without drift or wandering.
• 2 HW Precision Ground Cutting Edges (Z2) - dual carbide cutting edges shear material cleanly and efficiently, generating smooth bore walls and flat hole bottoms that are critical for tight, gap-free dowel connections.
• 2 Negatively Ground Spurs (V2) - the negatively sharpened spurs score the material perimeter before the main cutting edges clear it, preventing surface tearout and leaving a clean entry on coated panels, laminates, and veneered boards.
• Left-Hand (LH) Rotation - designed for multi-spindle CNC boring machines and panel processing centers that require LH-direction tooling, ensuring compatibility with the correct spindle positions on split-head boring units.
• 8 x 20mm Parallel Shank - the precision-ground shank fits standard boring machine chucks and adapters securely, minimizing runout and maintaining hole-position accuracy across high-volume production runs.
• 40mm Cutting Height - delivers sufficient boring depth for medium-series panel applications, accommodating standard dowel lengths used in cabinet and furniture panel construction.

Why This Product

• Left-hand rotation fills a specific tooling requirement on multi-spindle boring machines where both LH and RH spindles are used simultaneously - having the correct rotation direction prevents tool damage and guarantees clean, accurate holes on every spindle position.
• The combination of negatively ground spurs and precision carbide cutting edges addresses one of the most common problems in panel boring - surface tearout on laminates and coated boards - delivering production-ready hole quality without secondary sanding or repair.
• A 9mm diameter paired with a 40mm cutting height matches the most widely used dowel sizing in furniture and cabinet panel construction, making this drill a practical everyday workhorse for high-volume shops.
• The precision balanced centre point and HW cutting head work together to maintain positional accuracy and consistent bore quality across long production runs, supporting tight assembly tolerances in dowel-joined furniture and cabinetry.
