Of particular interest to aerospace manufacturers faced with the challenges posed by heat resistant super alloys, the WTX–Ti range of solid carbide drills from WNT (UK) offers geometry that features optimised web thinning. This assists in generating much shorter swarf, ensuring that the cutting area is kept clear.
The drill point on the WTX-Ti range also has an active centre cutting feature that provides greater centring accuracy as the drill enters the workpiece, says WNT.
Cutting data when drilling nickel-based alloys with WTX-Ti is between 35 and 45 m/min surface speed, with feed rates up to 0.2 mm/rev dependent on diameter and flute length. The WTX-Ti range is available in 3x and 5x diameter flute lengths as standard, with drill sizes between 4 and 20 mm, in increments of 0.1 mm up to 10 mm diameter.
