Waukesha, WI –Walter has introduced its new solid carbide chamfering drills; the X·treme Step 90 and the X·treme Pilot Step 90 for XD (extra deep) drilling applications.

The X·treme Step 90 is available in two versions, the Type 99 with internal coolant, and the Type 79 without. Both feature a 4-margin design, which is well suited to entering in uneven surfaces up to 5 degrees, uneven exits up to 45 degrees, and cross holes.

The drill has a point geometry (140 degree point angle) that makes it suitable for universal use. Diameter tolerance is m7, and shank diameter tolerance is h6 per DIN 6535 HE and HA. The drill’s XPL coating enables universal use and provides for secure chip evacuation plus and helps improve tool life.

The Walter Titex X·treme Pilot Step 90 solid carbide chamfering drill is designed for extra deep drilling. It features a 2-flute design, short length for maximum stability, 2xDc pilot length to provide the best alignment for the XD drill, diameter tolerance of p7, and a TFT coating for maximum tool life and minimum adhesion.

Both drills have a wide application range and are engineered for use on steel, stainless steel, cast iron, aluminum, heat resistant alloys, and hardened steels, as well as composites and plastics.
