Product Description


  • The c arbide with extremely fine particles makes the wear resistance of ball end milling cutter and cutting edge strength perfectly combined; The blade is covered with high-quality coating to enhance the wear resistance of the milling cutter and the lubricity of the cutter body, ensure the service life of the cutter and improve the working efficiency; The unique spiral edge angle grinded by the foreign first-class precision machine tool is sharp and wear-resistant, and the cutting is smooth, greatly improving the milling efficiency; Sharp four edge design, sharp cutting, fast speed, no vibration lines, no sticking to the knife; Large core diameter design is adopted, giving consideration to the rigidity of the tool and good chip removal. Strict and scientific groove type control makes the cutting and chip removal of the tool more stable.

1. Before using the carbide end mill, please measure the tool deflection. If the tool deflection accuracy exceeds 0.01mm, please correct it before cutting.

2. The shorter the carbide e extends out of the collet, the better. If the tool extends out longer, reduce the speed, feed speed or cutting amount.

3. In case of abnormal vibration or sound during cutting, please reduce the speed and cutting amount until the situation is improved.

4. Spray type and air jet type are preferred for steel cooling, which can improve the use effect of carbide end mill.

5. Note: Not suitable for low speed machines such as rotary table and electric hand drill.



Pre-hardened Steel, stainless steel, Die steel, steel plate, Heat-resistant steel,pipe, copper and aluminum, cast iron, Nonferrous Metal, Wood, Plastic,FRP and sO on. General-purpose operation slotting, rilling, profiling.

Cnc Milling Cutter 6mm 3 4 Flute Tungsten Solid Carbide High Feed Endmill End Mill



Q1: The tool breaks when the feed direction changes


(1) Use circular interpolation (NC machine tool) or temporarily stop (temporarily) feeding.

(2) Reduce (decrease) the feed rate before and after the direction change.

(3) Replace the fixture or spring collet.


Q2. Problem: The blade tip is partially chipped

(1) Use manual grinding to chamfer the corners.

(2) Change the forward milling to reverse milling.


Q3. Problem: Partial collapse of the cutting interface


(1) Change the forward milling to reverse milling.

(2) Reduce cutting speed.
