The Vario adds continuous speed adjustment without stopping the machine — allowing you to switch from roughing to finishing in 2 seconds.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the maximum drilling diameter on steel with the GB 35 Vario?\u003c\/summary\u003e\n\u003cp\u003eNominal capacity Ø 35 mm on S235 steel with HSS drill bit. For large diameter holes (over Ø 25 mm), always use the lowest speed, slow feed, and coolant — heat is the main enemy of the cutting edge. On stainless steel AISI 304, reduce the capacity by 30–40%. For core drilling, consult Krollit for specific capacity.
