NC Machine Reamer
Design: centring up to diameter 3.70 mm on both sides with 90° full tip, above with inner centring, with straight shaft diameter for standardised attachment in hydro expansion chuck and high-accuracy chuck. Due to the tight tolerance of the shafts the clamping accuracy is significantly improved. With cylindrical shaft, tolerance h6. Surface blank.
Reamer manufacturing tolerances:
- Full diameter and 1/10 mm dimensions H7,
- 1/100 mm dimensions from Ø 1.01 to 5.03 mm 0.000/+0.004 mm, over Ø 5.03 mm 0.000/+0.005 mm.
Application: For grating through holes, due to the short cut (from 3.8 mm) also suitable for grating blind holes.
