Metaalboor 6,5mm 5% Cobalt
Metal drills GRAPHITE (ref. no. 57H040) with diameters 6.5 mm are made of high quality M35 HSS alloy with 5% cobalt additive. 135° point angle and chisel edge correction allow for easy drilling without punching. Thanks to alloy resistance to high temperature, the drills are perfect for drilling holes in hardly machinable materials, like stainless steel, acid resistant steel, heat resistant steel etc.
