Audel professional HSS step drill UniBit, diameter 5-35 mm titanium, 2 cutting edges - conical drill bit - conical drill silver

Bought to use on plastic to make an existing hole bigger it worked a treat it was so easy. I could not use my cordless drill as the chuck was too small but it fit my standard electric drill with no problem. Handy little tool that I will keep on my tool box for other jobs.

Usually use G&J Hall cone cutters which are outstanding, but very expensive. For the price this is very good quality, and works well. It doesn't open up as quick or as cleanly, compared to the hall ones but im happy with it. Rusts quickly if you get it wet, so keep it dry

For the price this is bloody fantastic. So far I have used it to enlarge a hole in a plastic dashboard panel to 27mm and also to enlarge the mounting holes for a safe from 8 to 12mm. Plastic capable - Check 3mm steel panel capable - Check The cutter shows no sign of wear after either task. The hole it made was nice and clean in the plastic, metal may need some deburring afterwards as the cutter can leave some swarf attached to the workpiece. There is not a lot of tolerance between the steps so this tool will not be any use for thick materials. Anything more than 3mm will require drilling from both sides to obtain an even aperture or you'll end up with a cone shaped hole. You’ll need at least a 1/2” chuck on your drill to fit this bad boy in, the shank is chunky. Take the job nice and slow to avoid snagging or over drilling the hole too big. Remember, you can’t drill a bit back on.

I would not use this for precision work but it opens holes easily in suitable materials. Chunky enough that I have even used it by hand for a careful opening. Heavy and well made.

I bought this to fit outlets in a thin plastic enclosure. It cut the holes with ease but as the steps between sizes are so shallow I couldn't even get a clean parallel hole all the way through. a waste of Money.

It’s unfortunate that there’s no option for a negative one-star rating. I can’t stress enough how bad this product is. It failed to make a proper 32cm hole in 3mm thick aluminum. The edges and sharpness wore out within just five minutes. It only cost 11 euros, so I won’t bother returning it, but it’s been my worst purchase in quite some time.

The step drill hasn't let me down yet. Nice solid bit with printed sizes in the groove (will probably come off) handy as an electrician especially if you want to carry light. Fits the chuck of my Dewalt combi drill

As others have written you do get what you pay for in general. I'm normally a 4-or-5 star person, or 1. This is not terrible however it came pretty blunt ( I'd expect razor-sharp from the factory ). I'm assuming that the sharpness is a bit of pot-luck as some folk seem to have had a better experience than me. Also, the steps are a bit short so going through a fairly thin piece of mild steel I was already nudging the next size before the hole was through. Saving grace for the sharpness is that the flutes are straight, so you can get a stone or similar on the 2 edges; I did that and I now have a reasonable cutter at, let's face it, a very reasonable price.

Der Kegelbohrer ist solide gebaut und bietet ausreichend Führung nach dem vorbohren. Nach der Vorbohrung mit einem 5mm Holzbohrer konnte ich prima die Löcher mit dem Kegel erweitern. Trotz Handbohrmaschine (welche für einen solchen Kegelbohrer nur bedingt zu empfehlen ist) gab es kaum Verkantungen. Nur einmal gab es eine kleinere Absplitterung, aber dies war auch durch meine manchmal leicht unruhige Hand zu erklären. Super Preis und super Produkt. Es macht Spaß mit dem Bohrer zu arbeiten.
