The Freud 20 mm Cylinder (Hinge) Bit is a precision-engineered boring bit built for professional woodworking applications that demand accuracy and repeatability. Designed for use on automatic and manual multi-spindle boring machines, this left-hand rotation bit features industrial carbide tips that deliver superior performance and extended service life when drilling through composites, solid surface materials, veneered plywood, hardwoods, and softwoods. With its 10 mm shank, 20 mm diameter, and 57.5 mm length, this hinge boring bit is a reliable choice for cabinet shops, millwork operations, and any application requiring clean, precise cylinder holes.

Key Features

• Industrial carbide tips - provide hardness and wear resistance that outlast standard high-speed steel bits, reducing the frequency of replacements and downtime on multi-spindle machines.
• Two wing cutters and two spur cutters - work together to prevent bottom-side tear out, delivering clean entry and exit holes in delicate materials like veneered plywood and solid surface panels.
• 10 mm shank with adjustable top screw - ensures compatibility with most boring machines, making this bit a versatile addition to existing setups without requiring adapters or special tooling.
• Left-hand (LH) rotation - matches the spindle direction required by many multi-spindle boring machines, ensuring proper chip evacuation and cleaner hole quality.
• Wood case included - protects the carbide edges during storage and transport, extending the life of the cutting tips between uses.
• Freud Limited Lifetime Guarantee - backs the bit with manufacturer support, giving buyers confidence in long-term value and quality assurance.
• Made in Italy - reflects Freud's European manufacturing precision, as noted in the specifications.

Why This Product

• If you operate automatic or manual multi-spindle boring machines and need a consistent, tear-out-free hinge hole, this carbide-tipped cylinder bit is purpose-built for exactly that application - not a general-purpose drill bit adapted to the task.
• The industrial carbide construction makes this bit the right choice for high-volume shops working with a wide range of materials, including composites, veneered plywood, hardwoods, and softwoods, where edge quality cannot be compromised.
• Left-hand rotation is a specific requirement for many boring machine spindle configurations - this bit is spec'd correctly out of the box, eliminating compatibility guesswork when setting up your machine.
• Sold as a single bit (1x) with a protective wood case, this Freud cylinder bit is ready to install and store properly, making it a practical option for shops that maintain organized tool inventories and need reliable performance job after job.
