Developed specifically for high speed cutting of austenitic grades of Stainless Steel and various long chipping materials to a hardness of 850 N/mm2

VA-PM series

taps

Sutton VA-PM Series Taps made to DIN371/6 standard are manufactured from a Vanadium grade of Powder Metallurgy High Speed Steel (PMHSS) which incorporates a much finer grain & homogeneous structure than conventional HSS,this allows for higher hardness of the tool,whilst maintaining toughness.
TiCNite ® (TiCN) surface coating is standard on VA-PM Series taps,offering excellentresistance againstcold welding,which commonly leads to tap failure in stainless steel. Higher reliefs than standard taps,allowing the tap to cutfreely and generating less heatduring tapping.

Blind Hole Tapping:R50 VA-PM Spiral Flute Tap

Higher helix than standard taps for better chip transportation. 3 pitch lead-in lightens the chip load over a standard spiral tap,this eases up the stress on the tap when breaking the chip on reversal atfull depth. The flute design incorporates positive rake on the flute heel,producing a more effective cutting action on reversal. The 50Ëš righthand spiral is specific to this range of materials for efficient tapping from 1.5 – 3 x D.These taps are also suitable for tapping harder materials atlower speeds.

Thru-Hole Tapping:VA-PM Spiral PointGun Tap

Capable of efficienttapping up to 3 x D these taps are also suitable for tapping harder materials atlower speeds.
