The GB 28 S pillar drill has a greater working height for tall workpieces.\u003c\/summary\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eUp to Ø 28 mm on steel — does this capacity also apply to stainless steel and aluminum?\u003c\/summary\u003e\n\u003cp\u003eØ 28 mm is the nominal capacity on S235 steel. On AISI 304 stainless steel, the capacity is reduced by 30–40% — approximately Ø 18–20 mm with the lowest speed and abundant coolant. On aluminum, the capacity increases by 30%. For holes over Ø 20 mm on any material, always use the lowest available speed with controlled feed.\u003c\/summary\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCoolant system included — when is it necessary?\u003c\/summary\u003e\n\u003cp\u003eCoolant is necessary for: stainless steel (always), alloyed and hardened steels, large diameter drilling over Ø 15 mm on steel, serial production with close cycles. Coolant is not used on wood and plastic.
