The Freud 35 mm Cylinder (Hinge) Bit is a precision-engineered boring bit built for professional woodworking on multi-spindle boring machines. Featuring industrial carbide tips and left-hand rotation, this 35 mm diameter hinge boring bit delivers accurate, clean cuts in a wide range of wood-based materials - from softwoods and hardwoods to veneered plywood, composites, and solid surface materials. The two wing cutters and two spur cutters work together to prevent bottom-side tear-out, making this bit ideal for cabinetry, furniture production, and hinge installation applications where clean, precise bores are critical.

Key Features

• Industrial carbide tips - provide long-lasting cutting performance and resist wear even under heavy production use on multi-spindle boring machines.
• Two wing cutters and two spur cutters - work together to prevent bottom-side tear-out, resulting in clean, professional-quality bores with no chipping or splintering on the exit face.
• 10 mm shank with adjustable top screw - ensures compatibility with most boring machines, simplifying setup and reducing the need for adapters.
• Left-hand (LH) rotation - designed specifically for use on left-hand spindle configurations found on many multi-spindle boring machines, ensuring proper cutting geometry and optimal performance.
• 70 mm overall length - provides adequate depth capacity for standard hinge cup boring and similar applications without excessive tool overhang.
• Wood storage case included - protects the carbide edges between uses and keeps the bit organized, extending tool life and reducing the risk of damage during transport or storage.
• Freud Limited Lifetime Guarantee - backs the bit against defects, giving buyers confidence in a long-term tooling investment.

Why This Product

• Designed specifically for multi-spindle boring machines, this cylinder hinge bit handles both automatic and manual production environments - making it a practical choice for cabinet shops and millwork operations running high-volume hinge drilling operations.
• Industrial carbide tipping combined with precision spur and wing cutter geometry means fewer rejected parts due to tear-out or blow-through, directly reducing material waste on expensive hardwoods, veneered plywood, and solid surface panels.
• The left-hand rotation specification matches the spindle direction requirements of many professional boring machines, eliminating the guesswork of rotation compatibility when ordering replacement or additional bits.
• Backed by Freud's Limited Lifetime Guarantee and crafted with carbide tips designed for superior performance and maximum life, this bit represents a reliable long-term tooling solution for production woodworking and furniture manufacturing.

Frequently Asked Questions

What rotation direction does the CB35070L use, and why does it matter?

The CB35070L uses left-hand (LH) rotation. This means it is designed for left-hand spindle configurations on multi-spindle boring machines. Using a bit with the correct rotation direction ensures proper cutting action, clean bore walls, and prevents the bit from backing out of the chuck during operation. Always confirm your machine's spindle rotation before selecting a boring bit.

What materials can this 35 mm hinge boring bit be used on?

This cylinder boring bit is suitable for use on composites, solid surface materials, veneered plywood, hardwoods, and softwoods. Its industrial carbide tips and spur/wing cutter design make it effective across this broad range of materials while minimizing tear-out on the bottom face of the workpiece.

Is the CB35070L compatible with my boring machine?

The bit is supplied with a 10 mm shank and an adjustable top screw, which makes it compatible with most boring machines. It is also suitable for use with a drill press or hand held drill. Verify that your machine accepts a 10 mm shank before use.

Does this bit come with any warranty or guarantee?

Yes. The CB35070L is backed by Freud's Limited Lifetime Guarantee, which covers the bit against defects and supports its designation as a long-term industrial tooling solution designed for superior performance and maximum service life.
