Listen to someone who ran 100 of these in a commercial shop *by F*** on Reviewed in the United States on July 1, 2020* Title says it. We ran a lot of these and probably would’ve kept them going before the astronomical price increase. For what they are charging you’re better off with USA made end mills. Garr is a higher end end mill and from the right supplier cost $30 each and will outlast the speed tigers 3:1. We have had so many breaking and leaving a bad finish after little use they wear out fast. The early ones we ran at 300ipm however the last 10 packs we couldn’t go over 120ipm without snapping them. We can run Garr at 400ipm if it’s any comparison. Take a look at the photo of broken speed tigers. Also if you have an issue with them customer support is non existence. It’s a cheap end mill attempting to get a mod range price. These end mills are not as good as Molza which are only $13 each so unless you need the extra cut depth I highly recommend you take a pass and save your money. ### ⭐⭐⭐⭐⭐ Great cutter at this price point, uBridgeport for slotting operation *by M***D on Reviewed in the United States on September 29, 2019* 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. ### ⭐⭐⭐⭐⭐ Aluminum Shredder *by B***B on Reviewed in the United States on April 14, 2020* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/135155660-carbide-square-end-mill-3-flute-iaue3-8-3-1](https://www.desertcart.vu/products/135155660-carbide-square-end-mill-3-flute-iaue3-8-3-1) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-20*
