Notched point is a variation on the standard chisel point, providing faster starting and reduced drill wander.
118° point angles are ideal for use in materials such as mild steel and cast iron.
The 118° point creates easily controlled chips which are wide and thin.
Bordo reduced shank HSS drills are ground and then a black finish is achieved by steam tempering, a thermal process resulting in a porous tool coating.
This surface aids chip flow and heat dissipation.
The drill is then ground a second time to achieve a bright finish on the shank and cutting edges.
Sutton Tools presents a breakthrough in twist drill technology, the revolutionary Viper Bit.
Drill Bits with bite!
The Viper Bit has been developed specifically for the industrial trades person and the home handy person. For machine and hand held drilling in a wide range of ferrous & non-ferrous materials such as steel, aluminium, brass, wood & plastics. The Viper point design out-performs conventional HSS drill bits by delivering up to 2X faster drilling speeds. The 118° split point is self-centering, minimising wandering when starting and requires less pressure to be applied when drilling.
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.
