Bought these to remove a stainless steel Allen bolt in a plastic motorcycle panel. Couldn't get the drill in straight due to the position of the bolt so had to drill from 3 different positions all at different angles very carefully. Drill bits worked great and I carried out the task without damage to the panel which would have been irreplaceable without spending a lot of money. Really happy with my purchase.

not too good on hard steel studs, if slack will remove the stud other wise just drills a hole in it after a wile probably good on softer metals but stud removal is questionable

Sheared off exhaust bolt on 50cc scooter quite deep in the engine casing, I had tried to drill out with standard drill bits but had no joy. These drills bit into the broken stud and I gradually upped the size to bore to a normal hole. Sealey bits made the job easy, I used wd40 as a cutting oil and took my time, increasing the speed only when purchase on the stud became more difficult.

A brill idea now drills drive both ways, exhaust studs are hard and these did a good job, however I did snap the second thinnest one my fault for not being steady. Price wise a good buy though.
