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).
Sutton Tools Blue Bullet jobber drills are a general purpose drill bit designed for machine and hand held drilling ferrous metals. The blue finish reduces chip build up on the cutting edge and is a better choice when drilling ferrous materials.
Tungsten Carbide Tipped Hex Shank Ceramic Tile Drill Set
These Rotary Only ceramic tile drills provide outstanding performance and extended tool life in hard ceramic materials.
They feature a unique cutting edge geometry in conjunction with high temperature brazing to ensure reliable and accurate drilling in multiple hole applications.
Use of water cooling will extend bit life.
Although these drill bits are not recommended for drilling vitrified porcelain, their superior multi-facet tungsten carbide tip enables them to drill most materials of this type, albeit with a reduced tool life.
Specifically engineered for use in impact drivers these bits are also fully compatible with conventional rotary drills.
1/4″ hex shank facilitates fast tool loading in cordless impact drivers and quick change adaptors.
