7 Pieces Center Drill Bits Set, M2 High Speed Steel 60-Degree Angle Center Drill Bits Kit Countersink Tools for Lathe Metalworking Size 1.0 1.5 2.0 2.5 3.0 4.0 5.0

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.

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

Great value for money

Really accurate drilling centre use without a center punch even on tube. Fantastic . Wish I found them sooner. Excellent price.

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

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

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.

Já usei algumas, funcionam perfeitamente.

Sehr nützlich um an der Drehmaschine vorzubohren. Bisher wurden nur 2 Größen verwendet und das Ergebnis war top.

tagliano benissimo

Tout parfait
