Description
Version:
Version suitable for NC similar to DIN 8093 with straight shank ⌀ for standard chucking especially in hydraulic chucks or high precision collet chucks. This ensures the highest concentricity.
Tolerance specifications:
Size 0.6 – 0.9: Manufacturing / cutting edge tolerance 0/+0.004 mm.
Size 0.98 – 20: Reamer manufacturing or cutting edge tolerance to DIN1420 for H7 bore tolerance.
No need to procure special collets when using GARANT-NC reamers. With long flutes and left-hand helix.
