Sheffield-based WNT (UK) Ltd (
www.wnt.com) has announced further additions to its already extensive WTX Change range of replaceable carbide drill heads.
The new additions bring the advantages of WTX Change’s interchangeability to those companies machining steel with a tensile strength greater than 700N/mm2 and cast iron.
Available in incremental steps for diameters between 12.00 and 41.00mm, the drill heads of the WTX Change drills help to drive down consumable tooling costs, as they are regrindable; they also enhance productivity, with some customers reporting a 400% improvement in tool life in certain applications.
The new additions to the range are the Change P series; these feature a 138deg point angle and are coated with WNT’s Ti 750 coating for improved wear-resistance.
The Change drills for cast iron, designated GG, feature a shallower 140deg point angle and benefit from a titanium-silicon (TiSi) coating for improved performance.
These two new additions complement the existing UNI, VA and ALU WTX Change drills already available.
The heads are located by serrations on the drill body and held in place by a single screw, making change-over both quick and accurate, while ensuring that any interruptions to production are minimised.
Drill bodies for the WTX Change heads are available in 1x, 3x, 5x and 8x diameter as standard; delivery from stock is available across the range.
