Feature

●NC machine reamer
●Design: centring up to 3.70 mm diameter on both sides with 90° full tip, above with inner centring, with straight shaft diameter for standardized intake in hydro-stretch chuck and high-precision chuck. The tight tolerance of the shafts significantly improves clamping accuracy. With cylindrical shaft, tolerance h6. Blank surface.
●Reamer manufacturing tolerances:
●- whole number diameter and 1/10 mm dimensions H7,
●- 1/100 mm dimensions from diameter 1.01 to 5.03 mm 0.000/+0.004 mm, over diameter 5.03 mm 0.000/+0.005 mm.


Description

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.
Further information: nominal diameter: 8.90 mm. Blade length: 36 mm. Total length: 125 mm. Shaft diameter: 10 mm.
