Frequently Asked Questions

GB 28 S (pillar) vs GB 28 T (benchtop) — which one to choose?

The GB 28 S is the pillar version with a higher working height — suitable for tall and heavy workpieces that cannot be lifted onto a workbench. The GB 28 T is the more compact benchtop version, for those with limited vertical space or working on small parts.

Up to Ø 28 mm on steel — does the capacity also apply to stainless steel and aluminum?

Ø 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.

Is the included cooling system necessary?

Coolant is necessary for: stainless steel (always), alloyed and hardened steels, large diameter drilling over Ø 15 mm on steel, series production with close cycles. Coolant is not used on wood and plastic. For aluminum, kerosene or specific aluminum oil is used instead of emulsified water.

Are spare parts available?

Original spare parts available with 3–5 business days shipping. Customer support in Italian available.
