Description
Version:
The latest generation of universal HPC reamers. Extra-short teeth for increased cutting performance values. Optimised cooling strategy with radially arranged coolant outlets aligned directly to the teeth. For uncompromising applications in steel and stainless steel. Reliable machining of high-tensile steels up to 60 HRC. Version suitable for NC with straight shank ⌀ for standard arbors especially in hydraulic chucks or high precision collet chucks.
Very high concentricity and process reliability due to unequal spacing.
Tolerance specifications:
Configurable: Reamers finish ground to match your specification.
H7: Version for H7 bore tolerance.
0/0.005 mm: Manufacturing or cutting tolerance of nominal ⌀ DC.
