"This countersink is pretty good. The price is very reasonable and it seems to stay sharp, I've used it loads and it still does the job. Only reason I have marked it down is that it seems to get clogged if the wood you drill is wet."
"At the end of the day you get what you pay for and this little countersink was ideal for me as it's not something I'd use very often so didn't want to shell out on a more expensive one.
Used to to countersink screw hole in conti-board, made a nice tidy job and I had no problem completing my entire project with it (building a large vivarium).
Rated this at 4 stars, it's fit for purpose and does the job fine but obviously at the price I would imagine there are better quality ones out there - in my case though I didn't need to spend more on something that will most likely now lie in the bottom of the tool box."
"Unfortunately this was the only basic countersink my local Screwfix had in stock when I needed it.
It does countersink into everything I've tried, but once you're trying to hide heads over 5mm diameter you have to take breaks or you'll risk overheating the bit, scorching your work piece and possibly making itself even blunter than before.
On the plus side it does swap quickly with driver bits so you can sink and screw without messing with the chuck."
"Bought this after i misplaced my old one. It's fine, but that's about it. Out of the packet it was hardly the sharpest. After 30-40 countersinks into MDF it's served its purpose and will be thrown away."
"Bought this to replace a rose bit I had for donkeys years that finally went. I only used it a couple of times before it's cutting edge lost the same sharpness it had on the first go. It still works, but you have to spend a bit longer drilling and apply more pressure to get any where with it. For the price it's ok, but I would not recommended it to somebody who wants to use it on a regular basis."
They are 'cheap-as-chips', but they need sharpening regularly ( I use the grinder on my Dremmel to reasonable effect ). As another reviewer stated, they soon end up 'burning' through the wood, especially as I'm using mine on plywood.
They do have the advantage of the hex shaft which is great for quick changes of bits, with a hex bit holder, especially if your drill chuck has difficulty tightening properly on round shafts.
If you only use occaisionally and you're capable of sharpening it, then go ahead and buy one.
If you have loads of work to do then pay a bit more, for better quality, as it'll save time in the long run."
