Frequently Asked Questions
What is the drilling capacity of the GTB 16/550 LASER?
See the "Drilling capacity" data in the machine's technical table.
The capacity refers to standard unhardened steel. For harder materials or alloy steels, the actual capacity may be lower: reduce speed and feed to avoid stressing the spindle and tools.
How do you adjust the spindle speed?
Via mechanical belt or gear 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 bit 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) fittings 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 tap?
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 (Profi industrial models).
Benchtop models are installed on a robust workbench, while pillar or radial models require floor mounting with expansion anchors for stability during drilling.
