Saber HSS-Co5 (Cobalt) TiN Coated Triple Flute Round Shank 9 8034-S1

Saber HSS-Co5 (Cobalt) TiN Coated Triple Flute Round Shank 90 Deg. Countersink Set
Saber HSS-Co5 (Cobalt) TiN Coated Triple Flute Round Shank 90 Deg. Countersink Set
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).
