CMT 307.064.11 Dowel Drill 1/4" x 40 x 67mm RH is a precision-engineered dowel boring tool from CMT, built for clean, accurate blind hole drilling in solid wood, chipboard, MDF, HDF, and coated panel materials. With a 1/4" cutting diameter, a 40mm cutting height, and a compact 67mm overall length, this right-hand rotation drill delivers the boring depth and dimensional consistency demanded by furniture manufacturing, cabinet making, and panel processing workflows. The combination of a tungsten carbide (HW) cutting head, negatively ground spurs, and a precision balanced centre point makes this drill a reliable choice for dowel joinery on multi-spindle boring machines and CNC boring centers alike.

Key Features

• Super-strength steel body with HW (tungsten carbide) head - the carbide cutting head bonded to a high-strength steel shank resists wear under continuous production use, extending tool life and reducing replacement frequency in high-volume boring applications.
• Precision balanced centre point - keeps the drill on target from the moment of contact, reducing walking or deflection and producing accurately positioned holes for consistent dowel alignment in panel assemblies.
• 2 precision ground HW cutting edges (Z2) - dual carbide cutting edges shear material cleanly and efficiently, producing smooth hole walls suited to tight-tolerance dowel joinery in hardwood, softwood, and engineered panel products.
• 2 negatively ground spurs (V2) - the negatively ground spur geometry scores the material surface ahead of the main cutting edges, preventing tearout and delivering clean, flat-bottomed blind holes in laminates, coated panels, and veneer-faced boards.
• 8x20mm parallel shank - the standardized shank diameter and flat driving surface ensures secure, repeatable tool clamping in multi-spindle boring machine chucks and CNC boring center holders, minimizing runout and vibration.
• Right-hand (RH) rotation - matches the spindle direction of standard production boring equipment, making this drill a direct-fit replacement or addition to existing boring head configurations without special adapters.

Why This Product

• The negatively ground spur design addresses one of the most common problems in panel boring - tearout on laminated and coated surfaces - giving furniture and cabinet producers cleaner holes without secondary finishing steps.
• With a 40mm cutting height and 67mm overall length, this drill reaches the boring depths required for standard dowel connections in panel construction while fitting within the spindle spacing constraints of most multi-spindle boring machines.
• The tungsten carbide (HW) head and precision ground cutting edges maintain sharpness longer than standard steel drills, making this tool a practical choice for production environments where consistent hole quality across large batch runs is critical.
• The 8x20mm parallel shank with driving flat is a widely used standard for industrial boring equipment, so this drill integrates directly into existing multi-spindle CNC boring machine setups without requiring special toolholders or adapters.
