SABER Countersinks HSS-Co5 (Cobalt) Cross Hole Round Shank Set
- Saber HSS-Co5 (Cobalt) TiN Coated Cross Hole Round Shank 90 Deg. Countersink Set
- 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 provides 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.
- They also may be used in softer materials (such as wood or plastic) to create a countersunk hole for a screw.
- HSS-Co5 (Cobalt) countersinks are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
- Bronze Finish (gold oxide) surface treatment. The metallic brown coloured low temperature temper treatment is normally only used on cobalt tools for identification purposes.
- Gold Finish TiN Coating (Titanium Nitride) helps to dissipate heat and reduces friction and cold welding.
- The coating higher speed and feed rates can be achieved and tool life is greatly increased.
- The TiN coating is achieved by Physical Vapour Deposition (PVD).
