Freud 15 mm Diameter Cylinder (Hinge) Boring Bit is a precision-engineered carbide-tipped boring bit built for accurate, clean-cut hinge boring in woodworking and cabinet production. Designed by Freud for use on multiple spindle machines as well as drill presses and hand held drills, this 15 mm cylinder bit delivers the consistent performance that cabinetmakers and millwork professionals demand when boring hardwoods, softwoods, veneered plywood, solid surface materials, and composites. With a 10 mm shank, a 57.5 mm body length, and right-hand rotation, the CB15057R is a direct-fit solution for most automatic and manual multi-spindle boring machines.

Key Features

• Industrial carbide tips - resist heat and wear during high-cycle boring operations, extending tool life well beyond standard high-speed steel alternatives and reducing bit replacement frequency in production environments.
• Two wing cutters and two spur cutters - work together to prevent bottom-side tear-out, resulting in cleaner, splinter-free bores in veneered plywood and other tear-out-sensitive materials.
• 10 mm shank with adjustable top screw - provides compatibility with most boring machines, making this bit easy to set depth and swap into existing multi-spindle setups without special adapters.
• Right-hand (RH) rotation - matches the standard rotation direction of most drill presses and multi-spindle boring machines, ensuring proper cutting action and safe operation.
• 57.5 mm overall length - provides adequate reach for typical hinge cup and system boring applications without unnecessary overhang.
• Wood storage case included - protects the carbide cutting edges between uses, keeping the bit ready for precise work and reducing the risk of tip damage during storage or transport.
• Freud Limited Lifetime Guarantee - backs the bit against manufacturing defects, giving buyers long-term confidence in their tooling investment.

Why This Product

• Cabinet shops and millwork operations that need reliable, repeatable hinge boring in hardwoods and veneered plywood will benefit from the industrial carbide construction and multi-spur design - fewer rejected parts due to tear-out means less rework and wasted material.
• The 10 mm shank with adjustable top screw makes this bit compatible with most boring machines without modification, reducing setup time and tooling changeover friction in multi-spindle production lines.
• Freud's carbide-tipped cylinder bits are designed for use across a broad range of materials - composites, solid surface, plywoods, hardwoods, and softwoods - so a single bit handles the variety of substrates common in cabinet and furniture manufacturing.
• Backed by Freud's Limited Lifetime Guarantee, this boring bit is a long-term tooling choice rather than a consumable, making it a cost-effective option for shops that bore high volumes of hinge holes daily.
