Frequently Asked Questions
What is the drilling capacity of the TB 15 Plus?
See the "Drilling capacity" data in the machine's technical table.
The capacity refers to standard unhardened steel. On harder materials or alloyed steels, 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 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) tapers 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 tap chuck?
Only models with standard right/left rotation allow tapping with automatic tap release.
Check the "Right/left rotation" or "Tapping" specification: drills without mechanical reversal are not suitable for repetitive tapping.
What is the weight of the machine and what installation does it require?
The weight varies from about 25 kg (compact bench models) to over 250 kg (industrial Profi models).
Bench models are installed on a sturdy workbench, while column or radial models require floor mounting with expansion anchors for stability during drilling.
