Drill Clean Holes in Composites with Onsrud’s new Diamond Coated Parabolic Drill


Libertyville, IL. A diamond coated parabolic drill has been developed by Onsrud Cutter that is suitable for drilling both carbon fiber and graphite epoxy materials. The new drill overcomes typical problems such as delaminating, flaking, and splintering encountered while drilling composite materials. The drill is also a lower cost alternative to PCD tipped drills.


The Parabolic Flute design is able to evacuate a large volume of chips while the multi-layer nano-crystalline, six micron thick coating is resistant to wear and abrasion. The special split point reduces thrust, improves centering and the secondary point angles create a self-seating, reaming action that directs chips away from the inner hole wall.


Onsrud Cutter is the only cutting tool facility in the United States that manufactures high-speed steel, carbide tipped, solid carbide, diamond coated and PCD CNC router tooling. Onsrud manufactured their first router bit in 1920.
