Carbide Burr 1/4" (6mm) Shank

Konetool 1/4" or 6mm shank carbide burr serves in different industries such as automotive, aerospace, shipment building, and molding. Millions of carbide burrs are manufactured with a full CNC production line every year and distributed worldwide.

For our 1/4" or 6mm shank carbide burr, three common cuts, single cuts, double cut, and aluminum cut (non-ferrous cuts) carbide burrs are available from shapes A to N. For most of the shapes, all three cuts are in stock in 365 days. Other cuts are acceptable as a customization order (please refer to our customization page)

The single cuts and double cuts burrs are trusted on ferrous metals(cast iron, steel, stainless steel, etc.) for deburring, milling, and leveling work.


The Aluminum cuts are often used on non-ferrous metal works such as aluminum, nickel, and copper. And it is also ideal for some soft materials such as plastic and others.
