      A:  I do knife and tool sharpening for a side business, and I could not find a convenient way to sharpen this bit. However, the good news is that it lasts a long time,even when used on aluminum as I did, and it's not all that expensive.

        A:  Yes

        by|Feb 2, 2021

          A:  Yes, it will work, but don't do it too often. I bought mine to countersink holes in aluminum, and after 50-60 holes the bit showed significant wear. I discarded it at that point. Drilling steel will wear the bit four times faster - maybe 15 holes. I would suggest using oil to ease the cut and extend bit life.

          A:  The quick answer is yes...it can countersink a hole in 3/16 in. flat stock. Whether it is practical will depend upon the size of the hole that you are countersinking and how far you are going to countersink (a function of the fastener head geometry). If less than one-half of the thickness remains, the ability of the fastener to resist pull-out will depend upon how much of a load is being applied to the fastener.

          by|Oct 7, 2020

          A:  Yes it will work to countersink your hole.

          Answer This Question

          A:  The countersink is a single piece (cutter and shaft). It does not attach to a drill bit.

          A:  Yes. If the hex part breaks, the remainder can be chucked as a smooth drill would chuck.

          A:  Hey Tommy, technically, yes you could replace the drill bit. However, it would likely be easier and cheaper to replace the countersink you need. Thanks!

            Works great, built well, does the job!
            [This review was collected as part of a promotion.] I bought this for counter sinking the screws in my 8-year old son's workbench I built for him, and it worked great! It's really well made and easy to use. I highly recommend it!

              Great when used properly
              These Ryobi countersinks are great when used properly in wood. You MUST countersink BEFORE drilling the hole. This creates a gorgeous perfect hole. If you countersink -after- drilling the hole, you'll get an ugly rough hold with hard edges. You can somewhat fix this by spinning the countersink backwards. But it's not as good as doing it right in the first place by countersinking before drilling.

                Works Just Fine
                Quality is as good as can be expected at this price. For those who may read that others have had trouble with countersinks, here is a tip. These are low RPM tools. Especially in metal. For aluminum you should run it at 120 RPM or less. For steel, even slower. But it probably will have a fairly short life and you may want to find a more suitable example which is going to cost more.

                  Works okay for projects that don't require a fine finish. I had to return mine. Added a photo.

                    I purchased this online and picked it up in the store. I was a little concerned as a few of the reviews I read talked about it chattering or not creating a round hole. I was using this in 1/4 inch aluminum. It did not chatter at all with firm pressure and as long as you are drilling in straight there will be no problem with out of round holes.

                      This bit did a decent job with countersinks, but it's not for applications that require a high degree of accuracy. Running it in a cordless drill, I found it wandered quite far off center the deeper I got. This was mitigated somewhat by drilling a wide diameter pilot hole, but there was still some degree of "wander". The only time I'd use this in the future is in a drill press. A closer inspection of the bit shows a dull point and uneven grinds on the cutting edges. I'm pretty sure this is contributing to the bit's tendency to move off center during drilling. I tried both hard and soft woods with the same result. The good news is I didn't experience any chattering while using it. Overall, I'd try a different HSS bit, since this one is a little more expensive than other comparable bits that come with a more consistent grind.
