LEM Long Neck Solid Carbide End Mill with Four Cutting Edges ---High Hardness Processing Type
Features:
1、All dimension is fixed by our norm and also accept non standard order.
2、Tolerance of dc≤Φ0.15 0/-0.01, dc＞Φ0.15 0/-0.015;
3、Tolerance of shank h6
4、Cutting edge to center with tip angle
5、Dimension of chamfer on the corner C value:
D≤Φ3，C=0.02～0.1；D＞Φ3， C=0.1；
6、Helix angle 35°.
7、Shank taper angle β=16°.
Universal Endmills-High Hardness Processing Milling
Features:
□ Carefully selected super high hardness carbide and super heat-resistant HS coating, the milling has superior heat resistance, so all heat-treated material of HRC65 below can be machined.
□ High hardness and ultrafine particles low-Co cemented carbide, tiny plastic deformation effectively suppressed produced ultra high-speed processing, improved tool life.
□ Using special grinding tool technology to achieve a high shape accuracy and dimensional accuracy, high precision machining can be performed.
