"Purchased this as a spare to have kicking about in the workshop. I have to say it is incredibly sharp and after countersinking a couple of dozen holes in oak, it is still as sharp as it was when purchased. I expect it will last a fair while."
"Having purchased this inexpensive item, the first use I put it to was to countersink mild steel brackets. This tool worked perfectly gave no trouble and still seems a sharp at the end of the exercise as it was before I started. Good value for money"
"I used this on a thick hard wood door frame to countersink some large frame screws. This was the first time i have tried this and the results were excellent. The bit went through the wood cleanly and quickly, leaving a professional finish."
"Countersinks softwoods and hardwoods like the world is ending tomorrow. First time I used it in softwood, I just about drilled a very large hole where I wanted a small countersink. It's just that sharp, and cuts so smoothly.
Haven't had occasion to use it in metal yet, so can't comment on that, and have only done a few dozen countersinks on various woods, hence the 3 stars for reliablity. However, it has already lasted longer than some cheaper alternatives."
"I bought this HSS countersink in preference to some cheaper alternatives because I've had experience with them and because this was made from High Speed Steel I knew it would last a while and take a decent edge when resharpened. Having now tried it I can confirm it produces a good clean cut without chatter, even in very soft wood and am very satisfied with the product."
