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 or 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.

Application:

For reaming through holes, as the chips are evacuated in the cutting direction. Lead taper is suitable also for blind holes.

Note:

For reamers like No. 164340 and 164341 but with other diameters and fits see No. 164344 and 164345.
