Description

Version:

Even number of teeth with irregular spacing. The hole is accurately round and free of chatter marks. The cylindrical ground land on the plain cutting section smooths the hole and guides the reamer. With Morse taper shank.
Reamers finish ground for fit H7.

Application:

For reaming through holes, as the chips are evacuated in the cutting direction. Also suitable for blind holes due to the short chamfer lead.

Note:

For suitable reducing adapters for tools with MT shanks see No. 343000-343530.
