The Cogsdill Ellipti-Bur® is designed for deburring irregular hole surfaces, such as those generated by drilling into curved surfaces or drilling at an angle. It enables users to perform difficult deburring operations quickly and accurately without the need for jigs, fixtures, or special operator skills. Three models cover a range of hole sizes from 5/32 to 1 inch (3.96 to 25.4 mm).
- Self-Centering Pilot: Features a spring-loaded, self-centering conical pilot that locates and seats the tool for consistent results.
- Floating Blade Design: The blade remains free to react to irregular surface geometry, allowing for both radial displacement (from the elliptical shape of angularly-drilled holes) and axial displacement ("rise and fall" from saddle-shaped configurations in cylindrical surfaces).
- Automatic Self-Guiding: Produces a uniform break on the edge of the hole.
- Durable Construction: All essential tool parts are hardened and ground for durability. Blades feature two diametrically opposed cutting edges made from hardened high-speed steel with a finish ground, supplemental surface treatment for increased wear resistance.
- Operating Range: Determined by pilot diameter rather than cutter width.
\Blades for the EL-5XT are made from a premium grade high-speed steel and are recommended for applications where longer tool life is desired, such as when coolant is unavailable.*
