Feed f in steel < 1100xa0N/mm2:0.08 mm rev. Reaming oversize in diameter:0.05 mm - 0.1 mm Shank tolerance:h6 Colour ring:green Type of product:Phillips bit 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.
