Our 17-4PH Stainless Steel Hard Drill Bits and Hole Openers are engineered for maximum performance and durability when machining challenging materials. These tools are specifically designed to overcome the work-hardening tendencies of stainless steels, high-temperature alloys, and other tough metals. The cutting edges are fortified with a high-performance electroplating coating, significantly enhancing hardness, wear resistance, and heat dissipation. This results in extended tool life, faster cutting speeds, and superior hole quality. We specialize in processing customization, offering a wide range of sizes, point angles, and configurations to meet your exact application requirements, from standard drilling to specialized hole opener applications for enlarging or deburring existing holes.

• Tool Body: High-Grade Alloy Steel. This provides the necessary toughness and strength to withstand high-torque applications without breaking.

• Cutting Edge / Working Surface: Electroplated with a layer of ultra-hard material, typically Micro-Grain Diamond or Cubic Boron Nitride (CBN). This coating is what allows the tool to effectively cut into hardened 17-4PH stainless steel.

• Compatible Material: Specifically optimized for drilling and enlarging holes in 17-4PH (ASTM 630) Stainless Steel in its H900, H1025, and other hardened conditions. Also effective on other stainless steels, Inconel, titanium, and hardened tool steels.

The following table outlines the standard technical parameters for our electroplated drill bits and hole openers.

We understand that standard tools don't always fit unique applications. Our processing customization services allow you to tailor the tool to your specific needs. Customization options include:

• Non-Standard Diameters & Lengths: Any diameter or flute length (including extended reach) upon request.

• Special Point Geometries: Custom point angles, split points, or special grinds for reduced thrust, improved chip evacuation, or specific hole entry requirements.

• Shank Modifications: Custom shank dimensions (e.g., for specific collets), flat spots, or Weldon shanks.

• Tool Geometry for Hole Openers: Customizing the number of flutes, lead angle, and step configurations for multi-diameter holes.

• Scale of Production: We support orders from small-batch customization for prototyping to large-scale production runs.
