## Description

SPECIFICATIONS Shank Diameter: 3.175mm Cutting Edge Length: 17mm Overall Length: 38mm (Tolerance: ±1-2mm) Cutting Edge Diameter: 3.175mm; 10Pcs Innovative Nano Blue Coat Chemical Composition: Ni-La203 Physical Characteristics: 1. Enhance the hardness of the bits. 2. Reduce the frictional resistance coefficient of the bits at high speed to improve the smoothness of the machined surface. 3. Increase the heat dissipation performance of the bits to avoid the influence of the crystal structure change due to excessive temperature. 4. Reduce the phenomenon of chipping of the cutting edge. Enhance the elasticity of the bits. The impurities of the workpiece can be elastically skipped to avoid damage to the cutting edge. 5. Extend service life. 6. Since the carbide bit has high hardness and is relatively brittle, the machine speed range should be controlled during use. WHAT'S INCLUDED? 1 x Set (10Pcs Nano Blue Coat 2 Flute Flat Nose End Mill CNC Router Bits)

Review: Smooth cut and very sharp - I just used this bit on my small CNC machine and am very pleased with the results. Since I will be using it on wood, I can’t comment on how durable it would be on metal. For my application, it is perfect and at a great price.
Review: Great value - good quality. - I have used about four packages of these for my CNC. They last a good while, but the best thing is never feeling bad about changing to a new one with the low price. If you are cutting detailed 3D projects, this is not the right end mill. If you are cutting repetitive, low precision products, these are great. I have cut 100s and 100s of xmas ornaments over the last month, all using these bits.

### ⭐⭐⭐⭐⭐ Great value - good quality.

### ⭐⭐⭐⭐ Don't know how long they'll last, but they cut EVA well enough for the price.
*by S***H on August 31, 2022*

My goal with these was to avoid having to cut out EVA for Halloween costumes by hand. I'm still dialing it in but saw ok results by running them at 20K rpm and 65ipm through some 6mm EVA (and .75mm of MDF sac-board). They leave a cleanish left edge and a ragged right edge. Looks like there was still some wobble on the edge, so I'll probably slow it down a bit the next time I use them.
