- Premium M2 HSS — fully ground high-speed steel for exceptional edge retention and durability across multiple materials.

When to Use This Drill Bit
The C9STQRM030 in 3mm is designed for tradies drilling through steel, stainless steel, and sheet metal with a cordless impact driver. The ¼″ hex shank means instant bit changes onsite, and the step tip eliminates the time-consuming pre-drilling step. Available in sizes from 3.0mm to 13.0mm, with reduced-shank models available for larger diameters (14.0mm+).
