Drill Bits/SetsBORDO HSS Co5 Bright Cross Hole 90° Countersink
- Cross hole countersinks are ideal for countersinking and deburring in a wide range of materials including ferrous and non-ferrous metals.
- The intersection of the hole and cone form the cutting edge on the tool.
- The cone is not truly symmetrical as it is essential that the cone retreats away from the cutting edge as the tool rotates.
- 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.
