Product Description

8mm 9mm Carbide Corner Radius End Mill Cutting Tools For Steel Stainless Steel

Bull end mills are simply corner radius end mill cutters. These radius end mills are single ended tools used for making corner radii at the bottom of a milled shoulder. Corner radius end mill cutters have a stronger milling edge than square end mills, so feed rates may be increased and yield longer tool life and greater productivity. These milling bits may also be used in mold profiling applications with greater productivity than ball end mills. These mills are all solid carbide, and are available in many diameter sizes and lengths.

Specifications

E550 general processing milling cutter series adopt domestic high-quality fine grain tungsten steel material. Flexural strength: 3900mpa, grain size: 0.8μm, with coating (black / Bronze) by imported coating equipment. E550 milling cutters are with special angle design and strict quality control, which is especially suitable for ordinary medium and low carbon steel, alloy steel and other materials processing. With high precision quality control, and full inspection, all E550 series end mills are delivered with 100% qualification rate.

Standard Sizes

The process of production:

1. Order entry business arrangements, then prepared the raw material, sent to engineer to drawing.

2. The grinding to flat head and chamfering, or taper of the angle.

3. Inspector test the diameter, length, taper angle and tolerance of the material, then lasering.

4. Go to CNC machine working. Some time check the cutter when it producing.

5. Inspector test all of when the cutters finished.

6. If the cutters no need to coating, then we will package it sent to customer. If the cutters need to coating, we package it sent to coating.

7. After coating back, inspector will check it. Then sent to customer.
