SABER Countersinks HSS-Co5 (Cobalt) Cross Hole Round Shank

  • 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).
