40pcs End Mills CNC Router Bits, 1/8" Shank CNC Cutter Milling Carving Bit Set Including 2-Flute Flat Nose & Ball Nose, Nano Blue Coat & Titanium Coat, MC40A

I ordered collors but they were too small

This is a good variety of small bits for a reasonable price... I broke a couple but they are tiny and I was driving then pretty hard. The seem sharp, did a good job and are holding up very well.

The corn mill bits work great from wood to mild steel, on a router or milling machine the flat and ball end mills work about fine for soft materials.On the outer edge of each flute of the 2-flute mills, there is a continuous band of unground steel, which should taper inward- this causes the tool to rub slightly. There is visible variation in the depth of the grinding, causing the unground section to be sized differently along the bit, and even between multiple bit there is a visible difference. I did find two ball end mills that had good edges near the bottom, which I'm pleased with, I just have a hard time understanding how you get so much variation on such a small scale.You get what you pay for, and for what you pay for this is a decent set.

Excelente. Todp tal cual.

Arrived on time

Works good and they last long

Tried to cut aluminum with gold plated bits 1.75mm OD.Regardless of the RPM/FEED, aluminum will get hot and gum up the bit ruining the part.

Inexpensive, 1/8”, works well.
