Frequently asked questions
What is the drilling capacity of the GB 40 N geared drill press with rotary table?
See "Drilling capacity" in the machine's technical table.
The capacity refers to standard unhardened steel. On harder materials or alloyed metals, the actual capacity may be lower: reduce speed and feed to avoid stressing the spindle and tools.
How is the spindle speed adjusted?
Via mechanical gear or belt change in stepped models, via inverter or variator in Vario models.
Vario models allow continuous adjustment, while stepped models require moving the belt to different pulleys. Correct speed selection based on drill diameter and material extends tool life.
What spindle taper and type of tools does it support?
See "Spindle taper" in the technical table: typically MT 2, MT 3, or MT 4 depending on the model.
MT (Morse Taper) connections are international standards, and accessories (arbors, keyless chucks, reductions) are commonly available on the market. Krollit supplies original Bernardo accessories.
Does the drill allow tapping with a tapping chuck?
Only models with standard right/left rotation allow tapping with automatic tap release.
Check the "Right/left rotation" or "Threading" specification: drills without mechanical reversal are not suitable for repetitive tapping.
What is the machine's weight and what installation does it require?
Weight varies from approximately 25 kg (compact benchtop) to over 250 kg (Profi industrial models).
Benchtop models are installed on a sturdy bench, while pillar or radial drills require floor mounting with expansion anchors for stability during drilling.
