Saber 25mm 90 Degree TiN Coated HSS-Co5 (Cobalt) Triple Flute Countersink

About this item:

• Saber 25mm 90 Degree TiN Coated HSS-Co5 (Cobalt) Triple Flute Countersink
• Saber 25.00mm Triple Flute Countersink
• For countersinking and deburring in a wide range of materials including ferrous and non-ferrous metals
• The three fluted countersink is self centering with wide flutes and is used to provide a heavy chamfer in the entrance to a drilled hole.
• This may be required to allow the correct seating for a countersunk head screw or to provide the lead in for a second machining operation such as tapping.
• Use on medium to hard materials.
• Resharpenable.
• 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).
