Version:
Up to 5 mm with straight flutes; from 6 mm with left hand helix 7 − 8°. The reamer body is slit and can be adjusted by approx. 1/100 of the reamer ⌀ using the expansion screw (e.g. 20 mm ⌀ = 0.2 mm).
Application:
For opening through holes to a slight oversize. Use the straight fluted reamers only in holes which are not interrupted. Make sure that the screw is not left tightened when stored.
