BORDO HSS Co5 TiN Coated Single Flute 90° Countersink
Single flute countersinks are ideal for countersinking and deburring in a wide range of materials including ferrous and non-ferrous metals.
The fluted countersink cutter 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 light to medium materials.
Resharpenable.
M35 Cobalt High Speed Steel offers increased wear and heat resistance in alloy steels, stainless steels and other abrasive or difficult materials.
This increases tool life in all production applications.
Titanium Nitride (TiN) Coated Countersinks have a very hard gold coloured surface finish.
This coating is only a few microns thick and is achieved by Physical Vapour Deposition (PVD).
This treatment results in reduced friction, greater heat dissipation and reduced cold welding – which means higher speed and feed rates with greatly increased tool life.
As with all surface coated tools, performance will deteriorate after resharpening.
Sutton Tools TiNite® jobber drills are for high performance drilling. Lasts up to 6 times longer than standard HSS drill bits. For drilling metal & tougher alloy steels such as steel, stainless steel, copper, brass, aluminium & cast iron.
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.
Sutton Tools Silver Bullet jobber drills are a general purpose drill bit designed for machine and hand held drilling in a wide range of ferrous & non-ferrous materials such as steel, aluminium, brass, wood & plastics.
Sutton Tools Heavy Duty Cobalt jobber drills are industrial quality for drilling materials that have high hardness and tensile strength such as cast iron, bronze, hard steel & stainless steel. These drill bits feature a thick core for increased rigidity in hard materials.
