Review: Great for destroying easyouts and busted manifold bolts - 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 desertcart 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.
Review: Drill bits for drilling hardened steel - 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.

### ⭐⭐⭐ Products may be mis-labeled in amazon inventory
*by S***E on 31 July 2026*

The end mills are great, we use them all the time, unfortunately there appears to be a batch of 3/32" (ISE3/32 4T) end mills labeled and stocked by Amazon as 1/4" (ISE1/4 4T), despite returning we keep getting sent the incorrect one.
