End Mill Bits, HSS CNC End Mill Cutter for Wood, Aluminum, Steel, Titanium, Straight 4 Flute Mill Bit Set of 6（3mm,4mm,6mm,8mm,10mm,12mm）

purchased to make a recess in an aluminum heatsink. I used them in my drill press. not quite as good as if i had a real mill to run them in. used one of the larger ones to plunge and remove most of the material then cleaned up the edges with a smaller mill. Very happy with the results

These bits are good for what they are, cheap slow speed endmill bits for softer metals. I wouldn’t use them for much else but they do fine for this type of work.

Bits are sharp and well constructed. I was disappointed that they are not clear on the shank diameter. 3 bits are larger than I can use. The set measures a little off, but I can compensate. 2 of the bits were in broken cases. This makes the set too expensive for my needs. I would suggest being very careful when buying.

For some reason the seller listed these as 1/8",5/32'',1/4",5/16",3/8",1/2", but in the details admits that the set is actually metric and that the 3,4,6,8,10,12 is "close enough" to the correct measurement. I have no idea why they would do this, as it leads to confusion. If you need the end mills to be exact dimensions, this set will not work.

I knew for the price they weren’t any kind of quality but, they were just needed for milling holes in soft metal, the tips 3 of the bits weren’t even sharpe. Burred over. Unusable. Just spend the money on a higher quality set.

For the price this product is unbeatable. I used these to mill out 4 pieces 80% AR15 lowers. They worked flawlessly and remained sharp.

I HAVE BEEN CUTTING BRASS AN GERMAN SILVER THEY WORK GREAT AN THEY STAID SHARPSTHE PRICE WAS VERY REASONABLE
