## Description

SPECIFICATIONS Shank Diameter: 3.175mm Cutting Edge Length: 12mm Overall Length: 37mm Cutting Edge Diameter: 0.8-3.0mm; 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 End Mill CNC Router Bits).

Review: 折れにくい。 - 結構タフで折れにくい。CNC3018で12ｍｍ厚のプラスチック（ポリアセタール）から切り抜くのに使っています。アルミはちょっと苦しい。鉄はやめた方がいいです。
Review: Great little corn cobs - The 1/8 cob cut bits are monsters, Love 'em, wish I could buy them in a stand alone pack. I just sit like a cave man and watch them granulate steel. I've always thought that chips were the way to go but these little guys showed my something different. I thought that these were more for wood and such and only grabbed it off my shelf out of desperation but they cut well. I had to feed it a slow cutting speed (.001 or so per sec at 900 rpm) but it worked like a charm on 1045. I chewed one up after about an hour, but I had gotten a little impatient and dinged the very tip up. The flutes kept cutting! The price on these is good, like I said, just wish I could buy the 3mm in multi packs by themselves.

## Questions & Answers

**Q: will these cut aluminum?**
A: The machine can engrave aluminum as far as cutting it it would take a very long time depending on the hardness.  To engrave I would set the passing depth at  0.5mm and the feed rate between 150 and 300 mm/min, spindle speed between 300 and 500 rpm. Aim a cooling fan at the work piece and keep a vacuum handy.

**Q: Can It engrave on copper?**
A: It's possible, but I wouldn't recommend it. Engraving on metal, even one as soft as copper, would dull the bits quickly.

**Q: Why is amazon shipping from Baltimore to Kentucky and back to baltimore?**
A: All 2 day air packages go to the hub in Kentucky first.  You could ship something 2 day air to your next door neighbor and it will go to Kentucky first. Crazy, right?

**Q: Are these upcut or downcut?  Can this vital piece of information be added to your product specs please?**
A: I believe they are Burrs and neither upcut or downcut however, they have an appearance of being upcut. Although I have them, I have not used them yet.
