Solide Carbide-NC machine reamer
Further dimensions available on request.
bright
Design:
Ultra-finest grain-solid carbide, dimensions similar to
DIN 212. Centring on both sides with 90° full point, with straight
shank ∅ for standardised mounting in hydraulic expansion chucks
and high accuracy chucks. The clamping accuracy is significantly
improved due to the narrow tolerance of the shanks. With cylinder
shank. Tolerance h6. Bright surface.
Reamer manufacturing tolerances:
– full diameter and 1/10 mm dimensions correspond to H7,
– 1/100 mm dimensions from ∅ 1.01 to 5.03 mm have a tolerance
of 0.00/+0.004 mm, from ∅ 5.97 to 12.03 mm have a tolerance
of 0.00/+0.005 mm.
Application:
For reaming through-holes, also conditionally suitable
for reaming blind holes due to the short trim cut. Particularly suitable
for high alloy and annealed steels up to 52 HRC, casting materials
and soft non-ferrous metals such as aluminium and brass.
