Beskrivelse
Highly efficient standard drill with morse taper. For drilling steel, cast steel and cast iron – alloyed and unalloyed. Highly secure against fracture.
HSS:
Heavy-duty high speed steel for drilling holes in easy-to-machine materials with a strength of up to 900 N/mm².
Shape A: Cut chisel edge
Applications: for all normal drilling work using drills with a strong core, for drilling into solid materials with larger drill diameters. Advantages: good centring when starting to drill, as the length of the chisel edge is reduced to 1/10 of the drill diameter, and fewer pressure is required. Disadvantages: additional regrinding work.
