CMT Hinge Boring Bit - 35mm Diameter x 38.5mm Cutting Height, 10x20mm Shank, Right-Hand Rotation is a professional-grade carbide-tipped (HW) boring bit engineered for drilling precise flat-bottom hinge cup holes in cabinet and furniture construction. Designed for use with BLUM, SALICE, HAFELE, and HETTICH hinge boring heads - including the CMT334 Universal Hinge Boring Head - this bit delivers clean, accurate 35mm hinge cup bores in a single pass. With a 2-spur, 2-tooth geometry and a 10x20mm parallel shank, it seats securely in multi-spindle CNC boring machines, boring centers, and panel processing equipment for repeatable, production-quality results.

Key Features

• Tungsten Carbide (HW) Cutting Material - provides long-lasting edge retention and consistent cutting performance across high-volume production runs in solid wood, chipboard, and MDF.
• 35mm Boring Diameter x 38.5mm Cutting Height - matches the standard European hinge cup specification exactly, eliminating the need for secondary sizing or adjustment when mounting concealed cabinet hinges.
• 2 Spurs + 2 Teeth (Z2+2) - precision-ground spur geometry scores the material surface before the cutters engage, producing clean bore walls and flat-bottom holes with minimal tearout on veneered or laminated panels.
• 10x20mm Parallel Shank - engineered for direct mounting in multi-spindle hinge boring heads and CNC boring centers, ensuring secure, vibration-free seating during operation.
• Right-Hand (RH) Rotation - matches the standard spindle direction of BLUM, SALICE, HAFELE, and HETTICH boring heads as well as the CMT334 Universal Hinge Boring Head, making this bit a drop-in replacement on compatible machines.
• Compatible with the CMT334 Universal Hinge Boring Head - the three-spindle CMT334 head accepts this bit to bore all major hinge brand cup holes on boring and point-to-point machines, streamlining tool changes in mixed-production environments.

Why This Product

• The 35x38.5mm specification matches the European concealed hinge cup standard, so installers and cabinet shops get a precise, repeatable hole every time without trial-and-error adjustments to depth or diameter.
• Compatibility with BLUM, SALICE, HAFELE, and HETTICH hinge boring heads - as well as the CMT334 Universal Hinge Boring Head - makes this bit a versatile choice for shops working across multiple hinge brands without investing in dedicated tooling for each system.
• The HW (tungsten carbide) cutting material and Z2+2 spur-and-tooth geometry are specifically suited to the composite panel materials - chipboard, MDF, and plywood - most commonly used in cabinet box and door construction, extending tool life in high-cycle production settings.
• The 10x20mm shank provides a positive, stable connection in multi-spindle boring heads and CNC boring centers, reducing runout and helping maintain consistent hole quality across large production batches.
