## Description

Audel professional HSS step drill UniBit, diameter 5-35 mm titanium, 2 cutting edges - conical drill bit - conical drill silver : desertcart.co.uk: DIY & Tools

Review: Great wee tool , did the job - 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.
Review: Decent cone cutter - 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

### ⭐⭐⭐⭐⭐ Great wee tool , did the job
*by F***9 on 23 April 2018*

### ⭐⭐⭐⭐ Decent cone cutter
*by E***R on 30 December 2018*

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

### ⭐⭐⭐⭐⭐ Unbelievable price for this quality. Ideal addition for the toolbox.
*by M***P on 12 May 2019*

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.
