sisona 1/8 3/16 1/4 5/16 3/8 Carbide End Mills Set - Solid Carbide (Tungsten Carbide + Cobalt) - 5Pcs 4 Fulte CNC Mill Bits for Steel - TISIN Coated

At this point, Ive really only tested the 3/16 bit. Material removes cleanly, chips consistently. The first few cuts with this bit have been clean and crisp. The bit shows no wear, but for carbide, it really hasnt been tested hard yet. Reasonable price point, based on the anticipated bit life. As time progresses, Ill report on durability...

Awesome! Great Buy.... Very happy

put these in my mill and tested them on a few projects and they worked great! def recomend for the price!

Tested the 5/8” cutter in hot rolled steel, was able to do a full width cut at 2mm depth with a feed rate of 480mm/m on my CNC converted HF mini mill. Surface finish was excellent given the rigidity (or relative absence!) and I was very pleased with the speeds I was able to achieve - quite aggressive for me but felt I should put the cutter through much more than I ordinarily would for the purposes of this review. These cutters are definitely on my must buy list. Ran it dry and did four faces on two 1/2” x 3/4” x 4” pieces. Photos show finish from roughing operation and the blue chips it produced with no sign of cutter deterioration after removing a total of 1/4” over a length of 16”!

I finally got a chance to try out these endmills recently, and so far theyve been working great. Ive mostly used the 3/8, and its been perfect for my uses. I used it with some 1018 steel, 6061 aluminum, and O2 tool steel with my manual mill and it doesnt have any signs of wear yet. I hogged out some material on the piece of 1018, taking quite heavy cuts just to test the performance, and it worked well and cut like butter. I measured the grind of the flutes, and its only a few tenths small. I was able to hold a thou tolerance very easily. For the price of this set and the use Ive gotten from it so far even with only one of the endmills, Id say its 100% worth it. Ill update this review later on if I get a better scope of the durability or if any issues happen.
