The Vario adds continuous speed adjustment without stopping the machine — switching 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 in steel with the GB 30 Vario?\u003c\/summary\u003e\n\u003cp\u003eNominal capacity Ø 30 mm in S235 steel with HSS drill bits. 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. For AISI 304 stainless steel, reduce capacity by 30–40%. For core drilling, consult Krollit for specific capacity.
