Beskrivelse
Ø 19,5 x 238 x 140 mm. Highly efficient standard drill with Morse taper. High security against fracture. – Highly efficient standard drill with morse taper. For drilling steel, cast steel and cast iron – alloyed and unalloyed. Highly secure against fracture.
HSSE Co 5:
Heavy-duty high speed steel with 5 % cobalt content.
High ductility and heat resistance, for drilling holes in difficult-to-machine materials with a strength of up to 1100 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.
