AFUNTA 21pcs Centre Drill Bit Set, Self-Centering Hinge Tapper Core Hole Punch 5/64" 7/64" 9/64" 11/64" 13/64" 5mm 1/4" and 1 Piece Hex Replacement Drill Bits for Keys and 10pcs

I try to use it on my bike broken stud on exhaust. Was do the job properly. Just use a proper tools to make central punch.

All good does what it does only 1 thing does not come in case.no case

No more slipping when drilling through the holes on the product ur mounting. Excellent. Changable drill bits so should last a long time

Really good product , well built on top you you get extra hole bits in case you break any . All in all really good

poor quality, they all have a wobble when in the drill so difficult to keep workpiece still and centered, also the outer guide sheath does not return after each pilot drill hole being made especially on the smaller drill sizes, useless and frustrating, bought them to drill approx 200 pilot holes for metal stair spindle bases.

Brilliant kit, very handy spare bits.So easy and precise to use, makes the job very easy and quick.

Drills are crooked and off center,

Right product, that does the job

bon kit très pratique. Mes pentures s'ajuste très bien finalement

I've only needed to use the 5/64th as of right now. I figured instead of spending all that money for a single Center Drill why not get a whole lot that has different sizes, being a hobby woodworker, I'll use them all eventually.It comes with 10 Center Drill bit housings, 10 Bits inside those, 10 Extra Bits and a Hex Wrench.The drawback of these is the wrench it comes with is a size to small, so you'll want to make sure you got another that will fit it. When you go to tighten the Hex set screw up, you can't tighten to tight or you'll spin the wrench inside the set screw then you'll have to drill it out with an easy out.So be sure to find the right size hex bit for it before tightening it to much.Works as they should. Bits are sharp and goes right through the wood. Little wiggle but it's expected with them being cheaper.I'd recommend for a "Budget Buy", it works good enough, centers perfect just pair it up with the hole size of the hinge before chucking into the drill.

Muy prácticas al momento de hacer la guía.Buen producto, muy buen precio y muchas puntas adicionales. Compraría nuevamente

Ich habe mir die Bohrer angeschaut und einige ausprobiert .Mit der Qualität bin ich zufrieden und kann sie in meinen künftigen Projekten gut einsetzen .

Bien
