Delta Point drills have a multi-faceted cutting tip.
Rather than try and modify existing point types, or tweak the grind angles, Delta Point tip design required a revolutionary re-think of drill tip function.
The overall length of the cutting edge significantly exceeds that of conventional drills.
This means more edge doing the cutting and the results are simply extraordinary.
Drilling times for a range of split point and Delta Point drills consistently showed that Delta Point bits were twice as fast in mild steel.
During independent lifetime testing Delta point drill bits averaged 609 holes in 20mm mild steel, ten times more holes than split point drills.
DRILLS FASTER LASTS LONGER.
Bright Finish Twist Drills have no surface treatment and are supplied in the as-ground condition. These tools are suitable for general purpose use, particularly for non-ferrous applications.
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.
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.
