PRODUCT INFORMATION
Design:
- with straight shank dimensions
- up to Ø 3.75 mm with centring tips on both sides
- from Ø 3.76 mm with centre holes on both ends
Manufacturing tolerances of full-number Ø and 1/10 dimensions for tolerance zone H 7 of the reamed hole
1/100 dimensions
Nominal dimensions from 0.95 up to 5.50 mm = +0.004/0
Nominal dimensions from 5.51 up to 12.00 mm = +0.005/0
Use:
For mounting into hydro chucks and high-precision chucks. For through holes, because the chips are pushed into cutting direction. Due to L.H. helix only conditionally fit for blind holes
