Frequently asked questions
What is the drilling capacity of the gear-driven drill press GB 50 HS?
See the "Drilling capacity" data in the machine's technical table.
The capacity refers to standard unhardened steel. On harder materials or alloyed alloys, the actual capacity may be lower: reduce speed and feed rate to avoid stressing the spindle and tools.
How is the spindle speed adjusted?
Via mechanical belt or gear change in step models, via inverter or variator in Vario models.
Vario models allow continuous adjustment, while step models require moving the belt to different pulleys. Correct speed selection based on drill bit diameter and material extends tool life.
What spindle taper and tool types 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, reducers) are commonly available on the market. Krollit supplies original Bernardo accessories.
Does the drill allow tapping with a tapping tool?
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 weight of the machine and what installation does it require?
Weight varies from approximately 25 kg (compact benchtop models) to over 250 kg (industrial Profi models).
Benchtop models are installed on a sturdy workbench, while pillar or radial models require floor fixing with expansion anchors for stability during drilling.
