If this does not occur the cutting edge will lack clearance and rub rather than bite into the material. This clearance is referred to as cutting relief. The radially relieved single cutting edge provide fast stock removal with low vibration for chatter- free operation ensuring the smoothest finish. These tools are best used as deburring tools, where a burr, or sharp edge, from a previous machining operation needs to be removed for cosmetic and safety reasons, however they may be used in softer materials (such as wood or plastic) to create a countersunk hole for a screw, making it a reliable countersink bit.
