Walter has introduced its new Walter Titex solid carbide chamfering drills, the X•treme Step 90 and the X•treme Pilot Step 90 for XD (extra deep) drilling applications. The Walter Titex 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 for superior hole quality. The design is well suited to entering in uneven surfaces up to 5 degrees, uneven exits up to 45 degrees, and cross holes. In addition, X•treme Step 90's countersink of 90 degrees limits the need for deburring and facilitates superior chamfering, and correction of the countersink promotes the highest degree of process reliability. The drill has a point geometry (140 degree point angle) that makes it suitable for universal use. The drill's XPL coating enables universal use and provides for secure chip evacuation plus superior wear resistance and tool life. The Walter Titex X•treme Pilot Step 90 solid carbide chamfering drill 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. It has a 90 degree countersink to improve chamfering, reduce the need for deburring, and to support the entering of XD drills. Correction of the countersink gives this new drill exceptional process reliability. It has a 150 degree point angle and point geometry designed for the best positioning accuracy. Both the Walter Titex X•treme Step 90 and the X•treme Pilot Step 90 for XD solid carbide chamfering 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.
