Great. Good value

These seem good but I am not using them on steel.

I was surprised on these- they’re sharp enough for hobby home stuff, I wouldn’t use these for a pro job, fine on milder steel or brass/ ally, etc. in my myford ml7. I doubt they’re much good on 4140 etc

I needed some drill bits in a hurry for a project here at Farkham Hall Stores in Chepstow; we make specialist pad retaining pins for obsolete motorcycle brake calipers, which involves drilling small holes into a curved stainless steel surface, then countersinking them. The nice price of these bits left me thinking that they may not be up to much.How wrong I was and how pleasantly surprised by the superb job they did on a batch of pins. They look like they are going to last a while but when the time comes, I will certainly be back for more.

They do what they are supposed to, they seem to be of good quality, they have made a fair few center cuts and have not yet dulled. Good price for decent quality.

Used to drill through a rogue screw that was stuck. Not what it's designed for but did the trick

Well made and sharp.

I recently purchased a lathe and needed some centre drill bits, these were and great price and work really well in my low powered lathe.
