Product Description
The Freud 20 mm Cylinder (Hinge) Bit is a precision-engineered boring bit built for professional woodworkers and cabinet makers who demand consistent, clean results on multi-spindle boring machines. Featuring industrial carbide tips and a left-hand rotation design, this cylinder hinge boring bit delivers superior performance when drilling composites, solid surface materials, veneered plywood, hardwoods, and softwoods. With a 20 mm diameter, 70 mm length, and a 10 mm shank, it integrates seamlessly into most automatic and manual multi-spindle boring machines used in high-volume production environments. Backed by Freud's Limited Lifetime Guarantee, this bit is a reliable choice for cabinetry professionals who require repeatable accuracy and long tool life.
Key Features
- Industrial carbide tips - provide extended cutting life and maintain sharpness through demanding production runs on hardwoods, softwoods, composites, and solid surface materials
- Two wing cutters and two spur cutters - work together to prevent bottom-side tear out, delivering clean, accurate bores on veneered plywood and finished surfaces where surface quality matters
- Left-hand (LH) rotation - engineered specifically for multi-spindle boring machines that require left-hand bits, ensuring correct cutting direction and optimal chip evacuation
- 10 mm shank with adjustable top screw - makes the bit compatible with most boring machines without the need for adapters, saving setup time in production environments
- 70 mm overall length - provides the reach needed for hinge boring and cylinder boring applications in cabinet door and furniture manufacturing
- Wood case included - protects the carbide tips during storage and transport, preserving cutting performance between uses
- Freud's Limited Lifetime Guarantee - gives buyers confidence in long-term tool investment and protection against manufacturing defects
Why This Product
- Purpose-built for multi-spindle boring machines with its LH rotation and 10 mm shank, this bit fits directly into most automatic and manual multi-spindle setups without modification - reducing downtime and simplifying tooling changes in production shops
- The combination of wing cutters and spur cutters actively prevents tear out on the bottom face of the workpiece, making it the right choice for veneered plywood and finished panel applications where surface integrity is critical
- Industrial carbide tipping means this bit maintains its cutting edge significantly longer than standard steel alternatives, supporting consistent bore quality across repeated cycles without frequent tool changes
- At 20 mm diameter and 70 mm length, this cylinder bit matches the most common hinge cup boring specification used in European-style cabinet and furniture production, reducing the need to search for specialty tooling

Frequently Asked Questions
What type of machine is the CB20070L designed for?
This Freud cylinder boring bit is designed for use on multiple spindle boring machines - both automatic and manual - where left-hand (LH) rotation tooling is required. Its 10 mm shank with an adjustable top screw makes it compatible with most boring machines used in cabinetry and furniture production.
Why does this bit use left-hand rotation?
Left-hand rotation is a standard requirement for certain spindle positions on multi-spindle boring machines. Using the correct rotation direction ensures the cutters engage the material properly, producing clean bores and correct chip evacuation. Always verify your machine's spindle rotation before installing this or any boring bit.
What materials can this cylinder bit drill through?
The CB20070L is suited for drilling composites, solid surface materials, veneered plywood, hardwoods, and softwoods. The industrial carbide tips and spur cutter geometry help prevent tear out on the bottom face of the workpiece, which is especially important when working with veneered or finished panel materials.
Does the bit come with any warranty or protection?
Yes. This Freud boring bit is backed by Freud's Limited Lifetime Guarantee, reflecting the brand's confidence in the industrial-grade carbide construction and build quality of this tool. It also ships with a wood case for tip protection during storage.
