Designed to provide versatile, high-performance metalworking performance on any compatible impact wrench, the SiteH3ro holder allows the use of our comprehensive range of specialist SiteHero cutting tools, including: step drills, step reamers, taps and car reamers.

Easily attached to an impact wrench, the holder also ensures safe working at height and on job sites, particularly useful in construction and bridge-building industries where falling tools can prove a serious issue in cases of holder failure.

With SiteH3ro, you can perform a range of different metalworking functions without the need for a magnetic drill, transformer or other large equipment – this makes working in tight spaces or for long periods easier than ever.
