Accusize Industrial Tools3/4" 4 Flute M42 8% Cobalt TiAlN Roughing End Mill, 1102-0034

this was cheaper than my vendor and quicker. had little faith it would last or work.. but was throughly impressed with its preformace it took the job I was on and was able to slot in great time with great results and it worked on a few different set up.

For ruff in work the machinists seem to be pretty satisfied, for the price they are a good buy , but there are other high end brands they prefer

Fits well into 1/2” R8 Collet.Good for initial machining of pieces in 6061-T6 Aluminum and HR Steel.

For starters, I am not a machinist and don't have a milling machine or any real mill experience. I needed to elongate some 3/8" bolt holes for in 1/4" thick steel hinge brackets for a wrought iron gate. Tried filing and using a Dremel grinding stone to no avail, or at least too slow progress for my patience. So I chucked this thing up in my drill press and along with a cross-slide vice created my poor mans milling machine. This tool went through that steel in no time and made clean slotted holes. I used regular drilling / tapping fluid and it was a little noisy, but I was careful to not cut too fast. In maybe 5 minutes per hole and they were now clean 3/8" x 3/4" slots and perfect for getting the gates aligned again. When finished the tool still looked and felt brand new.

Sharp. Leaves a better bottom finish than expected. On my small mill it will take a 0.100” deep full width cut without a problem. Side milling 1/2” deep at 0.040 is no problem either.
