I've been milling aluminum for about 25 years and this bit will hog out aluminum faster than you will believe and leave a mirror finish. Works better than some of the name brand bits that cost $60/ea. Feed speeds that this can handle will likely surpass your machine. This bit also survived a dive crash about 1/4" into solid aluminum bar and didn't break.

I've tried these before but it's been a long time so I figured I'd give them a shot again. They cut well but they chatter like crazy on Spiral entries and while doing adaptive clearing in sharp corners. I'll stick to YG-1

Great endmill for the price. The tips are a bit fragile, I managed to break one moving off the part and was just a whisker too low by about .030". Other than that, they are sharp and leave a nice finish. Going to order another to replace the one I jacked up.

I needed to make some parts for a Hub-Motor being used in a BattleBot (see picture). The parts are for a small motor with small details, hence I needed a small 1/8" end mill for my 1/4" CNC (MillRight CarveKing) router.I bought these (SPEED TIGER IAUE 1/8" 3-flute Carbide Square End Mill for Aluminum Applications) (Amazon/Speed Tiger: please re-list these, they are awesome). The picture shows the two parts I made (five of each), total machining time was ~16 hours, all using the same end mill. The last part came out as well as the first part. I pushed the limit, with 20mm of the tool protruding from the collet. I did take it slow since it was my first time machining two-sided aluminum parts this complicated. My speeds and feeds were: 800mm/min (feedrate), 400mm/min (2 degree ramp), 20mm/min (plunge), all using a 0.5mm layer depth (it's a hobbyist CNC machine). As the Speed Tiger website shows, these 1/8" bits want a high speed (~29,000rpm), which is great for router CNC'ers... I dialed my router up to its max speed of 27,000 RPM.To make the 1/8" end mill work in my router's 1/4" chuck, I bought the "Amana Tool - RB-102 High Precision Steel Router Collet Reducer 1/4 Overall Dia x 1/8 Inner".Also, to make this project a success, I bought a compressor (Quipall 2-1-SIL-AL 1 HP 2 Gallon Oil-Free Hotdog Air Compressor), and a mister nozzle (Mist Coolant Lubrication Spray System for Metal Cutting Engraving Cooling Sprayer Machine for Air Pipe CNC Lathe Milling Drill - the picture indicates: Succkey “Full Sealed Mist Sprayer” S/N: AE 2150343). This enabled me to apply a high stream of compressed air (no lubricant or fluid was used) to keep the chips away and the aluminum cool. Both of which worked great.I am very happy with these 1/8" Speed Tiger IAUE 3-flute end mills.For another (larger aluminum) project, I bought the "SPEED TIGER IAE5 Carbide Square Nose End Mill with ZrN Coating for Aluminum Applications - 2 Flute - IAE5-1/4"2T-ZrN" -- I'll let you know how those work.

I bought two of the 3/8 3FL end mills, and am very impressed. On my little RF45 Clone CNC I was cutting 0.050" WOC 0.50" DOC (full depth on this particular part) at 75IPM in MIC6. It sounded great, and defiantly could have taken more. I will probably start pushing it to 0.075" WOC, even with my crappy spindle with tons of run out.Update:Pushed the DOC to 0.75" and WOC to 0.075" at 0.004IPT in 6061 T6 and it ran great. It was about all my little 2HP spindle could handle, but I think I will push it to 0.0045IPT next time I run that part... for science... All and all, great budget mill for the hobby world.

Used this cutter for a deep slotting operation in aluminum plate. Cutter (3/8" dia) performed very well, cutting full width .25" depth of cut per pass at about (power feed not CNC) .003 per tooth chip load. I used a straight plunge to start the cut and it did equally well but if you have a CNC I would use a ramping strategy.One cutter did 32 parts with over 72" of slotting in each part with no appreciable wear, cutter was still objectively as sharp as new (when I dropped it on the floor in a toolholder and broke it 😖). Used mist coolant system throughout the process and keeping it wet made a big difference in cut quality.Chip evacuation was good and surface finish on finish pass was outstanding. I bought a couple more just to keep on hand for future jobs. Great cutter at this price point.
