Product Specifications:
This HSSE double‑end R‑type center drill is designed for precision centering and chamfering on CNC lathes, machining centers, and manual machines. The 60° cone angle conforms to DIN333, making it suitable for standard centre holes. The R‑type (radius) design features a protective radius behind the cone, which prevents the drill from over‑entering and protects the subsequent machining operations.
The 3.15mm tip diameter provides a small starting hole ideal for precision components. With an overall length of 52mm and a shank diameter of 8mm, this center drill fits common tool holders. The HSSE material offers improved wear resistance and heat hardness – especially beneficial when centering stainless steel, which tends to work‑harden. The right‑hand cutting direction and 2‑flute geometry ensure stable, chatter‑free operation.
This tool is equally effective on aluminum, copper‑zinc alloys, carbon steel, and plastics. As a double‑ended tool, both ends are usable, effectively doubling tool life. Custom diameters and shank configurations are available for OEM orders. For high‑precision centering in stainless steel and other alloys, choose this reliable HSSE center drill.
📏 Standard sizes are shown in the charts above. For non‑standard diameters, lengths, or shank configurations, custom sizes are available – simply provide your requirements.
