R 25 Hredlinestubdrills

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.
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. 135 ° four facetdrill pointwith the splitnotched grind is designed to minimize the thrustproduced whilstdrilling,offering more accurate sized and positioned holesCNC generated profile flute shape at 1300 N/mm 25 ° helix produces a stronger wedge angle which is bestsuited for harder materials up to
2 Common shanks to h6 tolerance ensure accurate,straightholes with excellentconcentricity in operation.
