Product Description
Product Overview
Our 17-4PH Stainless Steel Hard Drill Bits and Hole Openers deliver exceptional performance and durability when machining challenging materials. These precision tools are specifically engineered to overcome the work-hardening characteristics of stainless steels, high-temperature alloys, and other tough metals. The cutting edges feature a high-performance electroplating coating that significantly enhances hardness, wear resistance, and heat dissipation, resulting in extended tool life, faster cutting speeds, and superior hole quality.
Material Composition
Tool Construction
Tool Body: High-Grade Alloy Steel providing exceptional toughness and strength to withstand high-torque applications
Cutting Edge: Electroplated with ultra-hard Micro-Grain Diamond or Cubic Boron Nitride (CBN) for superior cutting performance
Compatible Materials: Optimized for 17-4PH (ASTM 630) Stainless Steel in H900, H1025, and other hardened conditions. Also effective on other stainless steels, Inconel, titanium, and hardened tool steels
