1171 19.50mm CARBIDE RT80 RATIO S-DRILL

RT80A high performance drill with through body oil feed coolant suitable for the drilling of unalloyed, low to high alloyed steels including stainless and heat resistant steels. The HSS body holding the carbide tip absorbs vibrations and shocks that may occur during use. Special cutting point geometry, produces short chips, including soft, long chipping steels. The combination of this geometry and carbide tip allows high speed and feed rates to be used to produce high alignment accuracy with small diameter tolerance and excellent surface finish. Conform to DIN6538.Type 1171
