NC machine reamers / Ø 4.900 mm / H7 / DIN 212-3 / HSS-E / bright
NC machine reamers / Ø 4.900 mm / Tolerance zone: H7 / DIN 212-3 / HSS-E / bright / Form: B / Cutting direction: right-hand /
Execution: ≤ Ø 3.75 mm with external centres on both ends • > Ø 3.75 mm with internal centres on both ends • straight shank tol. h6 for clamping in hydraulic chucks and shrink fit chucks • for tensile strengths up to a max. 1000 N/mm² /
Application: The combination of NC machine chucking reamer and hydraulic, high precision clamping or shrink fit chuck respectively offers highest concentricity and process reliability for the production of holes to required tolerances. NC machine chucking reamers are similar to DIN 212 with straight shank (h6) for standardised tool clamping in hydraulic or shrink fit chucks. Short delivery for intermediate sizes.
