SPEED TIGER ISE Carbide Square End Mill - Micro Grain Carbide End Mill for Alloy Steels/Hardened Steels - AlTiBN Coating - 4 Flute - Fractional, 1/4 in

Sharp and true. Does what I expect from a carbide end mill.

I wasn't expecting to much out of these end mills due to the price. Let me tell you these .25 end mills are worth more. I used 1 endmill and ran it nonstop on my Bridgeport for 9 hours straight. After the piece was completed I checked the endmill and it was as when I first put the endmill in. I will be buying A LOT more of this brand. Now to test their .375 roughing bit tomorrow. Update: These end mills are way better then I ever gave them credit for. I had to make a few die molds for our production line. Material was 4140 for the tie downs and D2 for the actual dies. I was able to cnc mill everything with a single end mill. I used only air to cool the work piece and clear the path.

Speed Tiger bits are individually contained in rigid plastic cases and all 5 in a cardboard box then in either a paper shipping bag or cardboard box. I ordered both 1/4” and 1/8” bits together but they shipped a day separate due to possible shipping error. The bits are a great improvement over cobalt in drilling hardened steel and stainless and reasonably priced.

Nice cutters. They're doing a fine job. A good value.

Im currently working on a 96 impala and as i get to the exhaust manifold i noticed whoever had the car before me started the exhaust manifold gaskets but broke 2 of the bolts inside the block so just left it that way anyway long story short i tried getting the bolts out with a easy out bolt extractor but ended up breaking the tip of the easy ouot inside the block. I tried everything maybe 12 different bits and nothing worked finally after looking on amazon i found these bits with pretty good reviews so i bought the set of 5. When they got here i was hesitant but had no choice they worked so well i used 3 out of 5 bits and finally destroyed the easy out ntip and the broken bolt inside the manifold saving me alot of time and money. I will definitely be purchasing more in the future.
