Product Q&A

Q:What is a U drill?

A U drill, also known as indexable drill or blade drill bit, is an internally cooled drill bit designed for high-efficiency continuous drilling.

Q:How does a U drill differ from an ordinary drill?

U drills use hard alloy blades with inner and outer edge designs, offering better rigidity, higher feed rates, and larger processing diameters than ordinary drills.

Q:Can the blades of a U drill be replaced?

Yes, when the blades are worn, they can be replaced directly without the need for regrinding.

Q:What is the maximum drilling depth for a U drill?

The longest processing depth can reach 5 times the diameter of the drill.

Q:Can a U drill drill on inclined surfaces?

Yes, U drills can drill holes on surfaces with inclination angles less than 30 degrees without reducing cutting parameters.
