Description
Version:
Special HPC reamers of the latest generation, for machining aluminium, with improved tooth geometry and further developed carbide substrate. Extra-short teeth for increased cutting performance values. Optimised cooling strategy with radially arrangedcoolant outlets aligned directly to the teeth. 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 of the teeth and special profile of the round chamfer width.
Version with DLC coating ta-C.
Tolerance specifications:
Configurable: Reamers finish ground to match your specification.
H7: Version to DIN1420 for H7 bore tolerance.
