Description

Version:

With left-hand helix 7 − 8° and long taper lead, more than 1/5 of the cutting length. An even number of teeth with irregular spacing for accurately round holes, free of chatter. The cylindrical ground chamfer on the plain cutting section smooths the hole and guides the reamer.

Application:

For through holes (not for blind holes). Also very suitable for interrupted holes.

Hand reamers finish ground to match your specifications can be ordered as No. 160200.
For suitable tap wrenches see No. 148350; 148200; 148410 and extensions No.149400.
