The Freud 26 mm Cylinder (Hinge) Bit is a professional-grade boring bit engineered for precise, clean holes in a wide range of wood-based and composite panel materials. Featuring industrial carbide tips and a left-hand rotation design, this 26 mm diameter hinge boring bit is purpose-built for use on automatic and manual multi-spindle boring machines, making it an essential tool for cabinet makers, millwork shops, and furniture manufacturers who demand accuracy and durability at production speeds. Two wing cutters and two spur cutters work together to prevent bottom-side tear-out, delivering clean entry and exit holes in hardwoods, softwoods, veneered plywood, solid surface materials, and composites alike.

Key Features

• Industrial carbide tips - provide exceptional hardness and edge retention, extending the working life of the bit far beyond standard high-speed steel alternatives in demanding production environments.
• Left-hand (LH) rotation - engineered specifically for left-hand spindle boring machines, ensuring proper cutting geometry and clean results without improvising with a right-hand bit.
• 26 mm diameter cutting edge - the standard hinge-cup diameter for European-style concealed hinges, making this bit a direct fit for cabinetry and furniture assembly applications.
• 57.5 mm overall length with a 10 mm shank - sized for direct compatibility with most multi-spindle boring machines and compatible with the adjustable top screw clamping systems common to production boring equipment.
• Two wing cutters and two spur cutters - the four-point cutting geometry prevents bottom-side tear-out, producing professional-quality, splinter-free holes in veneered plywood and finished panel materials.
• Wood storage case included - protects the precision carbide edges during storage and transport, keeping the bit ready for consistent, accurate performance job after job.
• Freud Limited Lifetime Guarantee - backs the bit against manufacturing defects, giving professional users confidence in their long-term tooling investment.

Why This Product

• Designed specifically for multi-spindle boring machines used in cabinetry and furniture production, this hinge boring bit delivers the dimensional accuracy needed for European hinge cup installation in a single, repeatable operation.
• Industrial carbide tips maintain a sharp cutting edge over extended production runs, reducing downtime for tool changes and keeping per-hole costs low in high-volume shop environments.
• The four-cutter geometry - combining wing cutters and spur cutters - prevents the bottom-side tear-out that can ruin expensive veneered panels, making this bit a reliable choice for finished-surface plywood, hardwoods, and solid surface materials.
• The 10 mm shank with adjustable top screw compatibility ensures a secure, vibration-free fit in most boring machines, while the included protective wood case means the carbide edges arrive and stay sharp until they reach the workpiece.

Frequently Asked Questions

What rotation direction is this bit, and why does that matter?

This bit has left-hand (LH) rotation. Multi-spindle boring machines often use left-hand spindles for specific positions in a boring head configuration. Using a bit with the correct rotation direction ensures the cutters engage the material properly, producing clean holes and preventing damage to the bit or workpiece. Always confirm your machine's spindle rotation before selecting a boring bit.

What is the shank size, and will this bit fit my boring machine?

This bit uses a 10 mm shank, which is the standard shank diameter for most horizontal and vertical multi-spindle boring machines used in cabinetry and furniture production. The 10 mm shank is compatible with the adjustable top screw clamping systems found on most production boring machines. Verify your machine's chuck or collet accepts a 10 mm shank before installing.

What materials can this 26 mm cylinder boring bit cut through?

The industrial carbide tips on this bit are designed to bore through composites, solid surface materials, veneered plywood, hardwoods, and softwoods. It is well suited for production boring of European hinge cup pockets in cabinet doors and furniture panels, where clean, tear-out-free holes in finished surfaces are essential.

What guarantee does Freud offer on this boring bit?

Freud backs this cylinder boring bit with their Limited Lifetime Guarantee, covering manufacturing defects. This guarantee reflects the quality of the industrial carbide construction and gives professional users long-term confidence in their tooling investment.
