BORDO HSS Co5 TiN Coated Triple Flute 90° Countersink
Triple flute countersinks are ideal 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.
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.
These Rotary Only ceramic tile drills provide outstanding performance and extended tool life in hard ceramic materials.
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.
These ceramic tile drills can also be used to successfully drill in brick, concrete and other masonry materials.
Bordo Ship Augers are single twist bits, easily recognised by their lack of a central core.
The ship head features a single cutter with a coarse screw.
Their open pattern allows for the efficient evacuation of shavings and makes them ideal for deep hole applications.
The absence of cutting spurs (or lips) makes them less susceptible to deviation due to grain and imperfections making them the preferred option for timber with a strong grain.
Hardened cutting edge for long life in hard timber, including nail-embedded wood.
Ideal for deep hole applications.
Fully-forged bit for maximum durability.
Resharpenable.
