≤ Ø 3.75 mm with external centres on both ends> Ø 3.75 mm with internal centres on both endsTolerance for Guhring no. 455:≤ Ø 5.50 mm: 0.000/+0.004> Ø 5.50 mm: 0.000/+0.005Application rangeThe 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. manufacturing tolerance: ≤ Ø 5.50 mm: 0.000/+0.004 • > Ø 5.50 mm: 0.000/+0.005 • ≤ Ø 3.75 mm with external centres on both ends • > Ø 3.75 mm with internal centres on both ends • chamfer lead can also be used for blind holes, to do this, remove chips
