UNI

Bridging the gap between HSS and Solid Carbide Drills

series

R40-UNI jobber drills

Manufactured from a Powder Metallurgy grade of High Speed Steel (PMHSS) which incorporates a much finer grain & homogeneous structure than conventional HSS,this allows for higher hardness of the tool,whilstmaintaining toughness,and capable of operating athigh cutting edge temperatures.

AlTiNite

®

(TiAlN) surface coating is standard,offering low friction properties which reduces cutting edge temperature,improving the wear resistance of the drill,this combination provides superior tool life and work-piece finish.130 degree 4 facetdrill pointwith the profile web grind is designed to provide strength atthe drill point,whilstmaintaining excellentchip flow with optimized CNC generated profile flute shape at40 degree helix.Common shanks to h6 tolerance ensure accurate,straightholes with excellentconcentricity for machine colletoperation.The above features combined,provides the optimal performance in a wide range of materials,allowing higher speeds and feeds to be achieved,resulting in higher productivity and bridging the gap with carbide tooling.
