Walter Introduces Inserts for Exchangeable-Tip Drills for Deep-Hole Drilling in Low-Carbon Steels

Walter USA LLC (Waukesha, WI) has introduced the P6006 insert for exchangeable-tip drills that brings new levels of drilling efficiency to low-carbon steels, structural steels, and low alloy steels. Developed specifically for these unalloyed low-carbon and low-alloy steels, the P6006 features optimized geometry, with a sharp cutting edge and deep chip gash that leads to maximum process reliability and efficient chip breakage in low alloy or unalloyed steels. The insert also offers high centering accuracy, ideal for deep-hole drills in the above-mentioned materials.

The P6006 insert can perform up to 10 × Dc without the need for a pilot drill. The insert features a protective chamfer with the HIPIMS-PVD coating and the wear-resistant WPP25 grade, which leads to maximum tool life in stable conditions. Further, the insert has a 100° prism for the contact point in the body, and a 140° point angle with new geometry and thinner web. Optimum wear detection is provided by its light-colored yellow coating. The P6006’s current diameter range is  0.472-1.161 in. (12.00-29.50 mm), with plans to increase the diameter range with Walter’s next product release. This exchangeable-tip drill finds ready application in general metalworking and in the energy, automotive, and aerospace industries.

The P6006 insert can be used in all exchangeable-tip drills D4140, D4240, and D4340.
