Product Description
The Freud 20 mm Cylinder (Hinge) Bit is a precision-engineered boring bit built for accurate, clean-entry drilling in woodworking and cabinet production environments. Designed with industrial carbide tips and two wing cutters combined with two spur cutters, this hinge boring bit prevents bottom-side tear out - delivering smooth, accurate bores in composites, solid surface materials, veneered plywood, hardwoods, and softwoods. Whether used in a drill press or a hand held drill, this 20 mm bit is sized and configured for professional results on automatic and manual multi-spindle boring machines.
Key Features
- Industrial carbide tips - provide superior cutting durability and maximum bit life, reducing replacement frequency in high-volume boring operations.
- Two wing cutters and two spur cutters - work together to prevent bottom-side tear out, ensuring clean, accurate bores on veneered plywood and other finish-sensitive materials.
- 10 mm shank with adjustable top screw - ensures compatibility with most boring machines, making the bit easy to install and fine-tune without additional adapters.
- Right hand rotation - matches standard boring machine spindle direction, so the bit can be dropped into most multi-spindle setups without modification.
