Freud/Diablo CB35057R 35 mm Cylinder (Hinge) Bit is purpose-built for precise hinge boring, turning cabinet installations and door hardware into a smooth, efficient process. Designed to deliver clean, accurate holes every time, this bit family takes the guesswork out of 35 mm hinge bore work. What makes this bit stand out - Dual-cut geometry for clean bottoms: The two wing cutters and two spur cutters work together to prevent bottom side tear out, delivering crisp edges and a reliable hinge pocket without splintering or tear-through on the underside. - Optimized for hinge installations: Sized for standard 35 mm hinge bores, it creates perfectly aligned holes that keep doors hanging true and gaps even—vital for both cabinet projects and architectural millwork. - Versatile shank options for common machines: The CB35057R line ships with a 10 mm shank and an adjustable top screw, making it compatible with most boring machines. For those using drill presses, the 3557E variant is designed with a 3/8" shaft to fit most models right out of the box. Who this is for - Cabinetmakers and furniture builders installing concealed hinges where precision matters. - DIY enthusiasts tackling kitchen or bath cabinetry, hobbyist shops, or custom built-ins. - Pros and hobbyists who want repeatable, square hinge bores with minimal post-cut cleanup. How it solves real problems - Reduces bottom tear-out: The dual-cut configuration keeps the cutting action controlled, producing clean pockets even in plywood or dense hardwoods. - Increases accuracy and repeatability: A true 35 mm bore ensures hinge alignment stays consistent across multiple openings, cutting setup time and the need for rework. - Fits your workflow: Choose the shank that matches your tool—10 mm for most boring machines or 3/8" shaft for common drill presses—so you can work fast without adapters or compromises. Use cases and practical tips - Door installations: Set up indirect hinges in cabinet doors where a precise 35 mm bore guarantees even gaps and proper door swing. - Built-in applications: Install concealed hinges in bookcases, wardrobes, and display cabinets where clean edges and exact alignment are crucial. - Substrate flexibility: Whether working with plywood, medium-density fiberboard (MDF), or solid hardwood, the bite and edge quality stay consistent with proper feed and gentle cuts. Why this bit is a better choice than generic options - Specific hinge-bore design: Tailored for 35 mm hinge patterns, not a one-size-fits-all boring bit, reducing fit issues and rework. - Tear-out mitigation by design: The two wing cutters plus two spur cutters provide controlled cutting action and cleaner bottoms, a feature often missing in entry-level bits. - Long-term consistency: By focusing on a robust geometry and machine-compatible shank options, you get repeatable results project after project.
