Frequently Asked Questions
What is the drilling capacity of the radial drill RD 700 Vario?
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 to avoid stressing the spindle and tools.
How is the spindle speed adjusted?
Via mechanical belt or gear changes 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 threading with a tapping head?
Only models with standard right/left rotation allow threading with automatic tap release.
Check the specification "Right/left rotation" or "Threading": 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 (Profi industrial models).
Bench models are installed on a sturdy workbench, while pillar or radial drills require floor mounting with expansion anchors for stability during drilling.
