VFR2SB 2-Flute Impact Miracle Revolution Ball End Mill (S) for High-Hardness Steel Machining

Product features and specifications

Basic specifications and features of the product

Impact Miracle Revolution Coating

Newly developed (Al, Cr, Si)N coating with excellent oxidation resistance and lubricity, combined with (Al, Ti, Si)N coating, which has a proven track record for wear resistance and high adhesion, enables machining of hardened steel. It is a new coating that exhibits excellent wear resistance in

• (Al, Cr, Si) N-based
  oxidation resistant
  lubricity
• (Al, Ti, Si) N, ultra-fine cemented carbide
  wear resistant
  high adhesion

Proper use according to work material hardness

Achieves amazingly long tool life in machining hardened steel

2-Flute Ball End Mill

Strong S-shaped cutting edge/new negative cutting edge and weak helix cutting edge

• New flute shape: The cutting edge curve, helix angle and rake angle have been optimized to improve cutting edge strength over the entire ball edge area.
• Carbide base material: A high-grade grade that is ideal for machining high-hardness materials has been adopted.

Recommended cutting conditions

Notes on cutting conditions

• Note 1) If the rigidity of the machine or work material installation is low, or if chattering or abnormal noise occurs, reduce the rotation speed and feed rate in the same proportion.
• Note 2) If the depth of cut is small, the rotation speed and feed rate can be increased. Also, if processing accuracy is important, lower the feed rate.
• Note 3) α is the inclination angle of the machined surface.
