The Freud 17 mm Diameter Cylinder (Hinge) Boring Bit is a precision-engineered carbide tipped boring bit built for demanding woodworking and cabinet hinge drilling applications. Designed specifically for use on multiple spindle boring machines, this left-hand rotation bit delivers accurate, clean holes in a wide range of materials - from hardwoods and softwoods to composites, solid surface, and veneered plywood. With a 10 mm shank and a total length of 57.5 mm, it integrates smoothly with most automatic and manual multi-spindle boring machines as well as drill presses and hand-held drills, making it a versatile choice for professional shops and production environments alike.

Key Features

• Industrial carbide tips - provide exceptional hardness and edge retention, meaning longer intervals between replacements and consistent hole quality across high-volume production runs.
• Two wing cutters and two spur cutters - work together to prevent bottom-side tear-out, delivering clean entry and exit holes in veneered plywood and other surface-sensitive materials.
• 10 mm shank with adjustable top screw - ensures compatibility with most boring machines, reducing setup time and eliminating the need for adapters.
• Left-hand rotation (LH) - engineered specifically for multi-spindle machines that require counter-rotating bits, ensuring proper chip evacuation and accurate boring without repositioning.
• Wood case included - protects the carbide tips during storage and transport, preserving cutting edge quality and extending the usable life of the bit.
• Freud Limited Lifetime Guarantee - backs the bit against manufacturing defects, giving buyers long-term confidence in their investment.
• Made in Italy - see Specifications for Country of Origin details; Freud's manufacturing heritage reflects decades of precision tooling expertise.

Why This Product

• Purpose-built for hinge boring on multi-spindle machines - the 17 mm diameter is a standard hinge cup size, and the LH rotation matches the spindle direction of counter-rotating boring heads, so production runs go smoothly without bit substitution or workarounds.
• Carbide construction over standard high-speed steel means this bit stays sharp significantly longer when cutting abrasive composite materials and solid surface substrates, reducing downtime spent swapping or resharpening tooling.
• The dual spur and dual wing cutter geometry prevents tear-out on veneered plywood and laminated panels - critical when surface quality affects the finished product, such as in cabinet and furniture manufacturing.
• The included wood storage case keeps the precision-ground carbide tips protected between uses, making this bit a practical choice for shops that rotate tooling across multiple setups and need bits ready for quick deployment.
