Dewalt Extreme Impact HSS-G stappenboor (4-12 mm, voor gebruik in boormachines (accu en kabel)) DT5026-QZ

Yes this is expensive but having blunted so many cheap step bits I " bit" (see what i did there) the bullet and lashed out for this one based on reviews - it doesn't disappoint... "hot knife through butter" is the expression commonly used and its true, its incredible through thick steel so is definitely worth having in your tool kit

Très bonne qualité

This is by far the most durable and fastest metal drill bit I've ever worked with. I've made a couple of hundred holes into 3mm sj300 and at least 500 into a ø42mm galvanised tube. Also on higher speeds thanrecommended. I can barely find wear under magnifying glass. Terrific product!

Duro y duradero. Este tipo de herramientas si no la usas lubricada, por muy buenas que sean, dejan de serlo.

Molto utile
