HP Step Drill • Coolant • Steel / Iron
The High Performance (HP) Beyond step drills with through coolant for steel and iron are perfect for creating holes with multiple diameters. With the ability to perform drilling and chamfering in a single operation, these step drills streamline the holemaking process, eliminating the need for multiple tool set-ups and reducing setup time. The HP point design features a progressive rake angle and enables high feed rates - enhancing efficiency and precision in drilling operations. As a result, the HP solid carbide step drill for steel and cast iron stands as a versatile and efficient solution for industries seeking to optimize their machining processes for steel and iron components.
