8799D

Special type with differential helix, for maximum performance in roughing and finishing materials with hardness up to HRC 54. It allows a significant reduction in vibration, better chip flow, less power consumption, reducing the noise level, high degree of finish of the machined surface, without a trace of self-generating chatter. Longer life, higher speeds and feeds.
With special FIRE coating for maximum protection of the tool to cracking, maximum resistance to heat and humidity, which increase the life and performance. Micro-grit carbide type DK 460 UF high plasticity for a greater flexibility in processing and therefore less chance of breakage.
Very fine surface finish and dimensional precision.

Long series DIN 6527 L. Type N with 4 helical cutting edges to 35°/38°. Cutting right. Front tooth in the middle.
Cylindrical shank DIN 6535 HB.
