CMT 307.100.11 Dowel Drill 10 x 40 x 67mm RH by CMT is a precision-engineered carbide-tipped boring tool built for clean, accurate blind hole drilling in furniture panels, cabinet components, and solid wood assemblies. With a 10mm cutting diameter, a 40mm cutting height, and a compact 67mm overall length, this right-hand rotation drill is sized for medium-depth boring tasks on multi-spindle machines and CNC boring centers. The HW (tungsten carbide) head paired with a super-strength steel body delivers the consistency and edge retention that production woodworking and panel processing demand.

Key Features

• HW (tungsten carbide) head bonded to a super-strength steel body - resists wear during high-cycle production runs, maintaining boring accuracy across chipboard, MDF, hardwood, and coated panels without rapid edge degradation.
• Precision balanced centre point - locates the drill on center immediately at contact, preventing walking or skidding and ensuring repeatable hole placement for tight-tolerance dowel joinery.
• 2 precision-ground carbide cutting edges (Z2) - shear through panel material cleanly to produce flat-bottomed blind holes with consistent depth and minimal fiber tear at the bore wall.
• 2 negatively ground spurs (V2) - score the material perimeter ahead of the cutting edges, delivering crisp, tear-free entry holes on laminates, coated panels, and veneer surfaces where surface finish is critical.
• Right-hand (RH) rotation - matches standard spindle direction on the majority of CNC boring centers and multi-spindle panel boring machines, allowing direct fitment without adapter changes.
• 8x20mm parallel shank - provides a secure, concentric grip in standard boring machine chucks and collets, reducing runout and vibration during blind hole drilling.

Why This Product

• The negatively ground spurs score the panel surface before the carbide cutters engage, making this drill a reliable choice for laminated and coated board production where chipout at the hole rim would require rework or scrap the panel.
• At 10mm diameter with a 40mm cutting height, this tool is sized for the medium boring depths required in furniture carcass construction, cabinet back-panel doweling, and shelf-pin drilling - applications where a shorter drill would not reach and a longer one would create unnecessary flex.
• The precision balanced centre point combined with 2 carbide cutting edges supports high-speed, high-repeat boring cycles on multi-spindle CNC equipment without sacrificing hole-to-hole positional consistency.
• HW carbide construction maintains sharpness through extended production use in demanding materials including MDF, chipboard, and hardwood, reducing tool change frequency and downtime on panel processing lines.
