A Brand® AE-BM-H (8530)

4-flute high-precision finishing carbide ball end mill for high-hardness steels

Overview

4-flute high-precision finishing carbide ball end mill for high-hardness steels

Features

Variable Negative Spiral Gash

Controls chipping while securing cutting quality by making the negative angle weaker near the outer periphery; chipping resistance is enhanced in combination with the weaker helix angle specification

Superior Ball R Precision

Secures stable R accuracy across 180°

Thickness at Center

Thickening of the center core to prevent deformation of the ball tip and improve control of chipping

Superior Shank Accuracy

Supports h4 tolerance (0/-0.004)

Ideal for Shrink Fit Holders

Lineup of short-shank type suitable for shrink fit holders

Smooth Surface Treatment

Improves surface accuracy by smoothening coating surface
