Saber Essentials TiN Coated Cross Hole Round Shank 90° Countersink Set

• Set contains 10, 21 & 28mm countersinks.

Features

• 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.
• Gold Finish TiN Coating (Titanium Nitride) helps to dissipate heat and reduces friction and cold welding.
• The coating allows higher speed and feed rates and tool life is greatly increased.
• The TiN coating is achieved by Physical Vapour Deposition (PVD).
