Good product.. I've been surprised by this little cone drill bit. Really good...! Got a holes in 3 mm bar from 11 mm to 20 mm haslle free. 7 Jun 2015
The hole truth Well-made, sharp. Easily did the job, through 5mm steel plate. This is the cheaper option and haven't tried in comparison to others but I would recommend. 25 Nov 2014
Perfect for pre drilled holes I bought this as cost was cheap compared to the other step drills on offer. Was a bit hesitant as normally a cheap drill bit doesn't last anywhere near as long as an the expensive counterpart. I was impressed it easily cut thru steel plate that had a 10mm hole already and opened out to 20 mm without any difficulty. It cut thru quick and easily bearing in mind the plate was 6 mm thick. 27 Sep 2014
