OSG 3042001 | A Brand 1.00mm Diameter x 4.00mm Shank x 0.80mm LOC x 5.00mm OAL x 0.50mm Radius x 25 Degree Helix Angle 2 Flute DUROREY Coated Carbide 8510 Ball End Mill

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

Features & Benefits:

• 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/-0004)
