Technical FAQ

Frequently Asked Questions on Aerospace Drills

What makes cobalt drill bits superior for titanium and Inconel®?
M42/M35 cobalt high-speed steel maintains red hardness even at high cutting temperatures generated by tough alloys. The 135-degree split point eliminates center punching requirements by self-centering instantly upon contact.
What is the difference between NAS 907 Type J and standard jobber drills?
NAS 907 Type J is an exacting National Aerospace Standard governing heavy-duty web thickness, fluting geometry, and split-point tolerance specifically designed to prevent binding and work-hardening during manual and automated airframe assembly.
How do Double Margin drills improve structural hole quality?
Double margin drills feature a secondary guide margin on each land. This provides enhanced support against the hole wall, maintaining extreme roundness and finish accuracy, often eliminating the requirement for a secondary reaming operation.
