Beskrivelse
Ø 10,5 x 133 x 30 mm Ideally suitable for drilling largish drilling diameters on all commonly-used drilling machines with a clamping chuck up to 13,0 mm. – High-performance rolled, steam-treated twist drill made from heavy-duty high speed steel. The manufacturing procedure (no structural disruption) solidifies the material making it more elasticated. This makes it more resistant to fracture and suitable for robust drilling units (e.g. hand-held drilling machines).
Heavy-duty high speed steel for drilling holes in easy-to-machine materials with a strength of up to 900 N/mm².
