The same can be said for a typical countersunk screw, i.e. e Cut at an angle of 82° for countersink
Yes, I use both an impact driver and a driver drill with them.
Now I understand what you're saying. You can easily make a shallow v-neck by adjusting the collar. shaped countersink with no vertical walled boring like a bung, so the top of a flat head screw sits perfectly flush with the surface
I've never attempted to sharpen them, but if I did, I'd remove the drill bit and use a fine metal file or a honing stone to do so.

I bought it because it was cheap and had a lot of positive feedback. I needed a second set for the woodshop to go with my Lee Valley set, which cost three times as much. That was a huge blunder. Instead of four flutes, the counter sink cutters have only two. They work fine in pine or plywood, but chatter and leave an elongated hole in hardwood (see photo). I thought I had the drill in reverse when I first used it in oak because it cut so slowly and chattered. If you're a weekend warrior or a woodworking hobbyist who only needs to countersink holes once in a while, it'll probably suffice; however, if you're a commercial user like me who uses your tools frequently, you'll need to invest in a higher-quality tool. I gave this set away and placed an order with Lee Valley for a new set.
They're a little pricey, but you definitely get what you pay for, and perhaps a little more, when compared to less expensive products that break or don't perform well. br>br>They're hefty in the hand, sharp, and the bits actually fit into the countersink sleeves! I bring this up because many of the bits on others I've owned are noticeably small for the sleeve hole, and as a result, they're never properly centered, resulting in holes that aren't the right size or shape. br>br>I like the set screw system because of its large size and clean machining. They're simple to loosen and tighten after adjusting drill depth, and they stay put regardless of how many holes you drill in softwood or hardwood. br>br>Because this design has two chamfered flutes, I find that using a high drill speed and taking my time to complete the cut gives me the best results. (That last piece of advice is applicable to the majority of my work with power tools - I'm going to take my time and let the tool do the heavy lifting. )br>br>They're also made in the United States. If you're looking for a set of countersinks, I recommend spending a little more money on these. Quality is the best value, as the old adage goes.
I've been using them for a while and have had a lot of success with them. The countersink heads themselves are good, and they leave clean holes. The drill bits, on the other hand, are worthless. I've already snapped two of them in half while attempting to use them on pine, of all things. These will snap in half if the drill bit is not perfectly straight. The ease with which these fell apart irritated me. I replaced them with inexpensive bits from a big box store, and they work fine; fortunately, the countersink heads accept common drill bits. Overall, they do a good job of making countersinks, but if your experience is anything like mine, expect the bits to break frequently. It's a pity because if the bits were better, this would be a fantastic product; however, I'm disappointed and would not buy these again.
This is a fantastic product that is made in the United States. I highly recommend this product, and I believe the previous negative reviews were due to operator error after using it on my hickory cabinets. Hickory is a notoriously difficult wood to work with, but these bits performed admirably. A couple of pointers for first-time users of these bits: to avoid breaking the bit, make sure you drill straight every time. To avoid the drill bit becoming clogged with chips, you must pick the drill in and out of the hole. They'll work great if you do it this way! After you've used them on hickory, any other wood will be a breeze!.
Stop, this isn't working. I like the bits, but the depth stop is a little off. It fits on the shank too loosely, and it's impossible to tighten the nut without the depth stop slanting away from the drill bit and becoming non-coaxial. One issue is that unless you want a fairly deep counter-top, you won't be able to find one. The depth stop collar is only partially under the nut that holds it in place in the bore hole. When combined with the loose concentric fit and engagement between the depth-finding depth-finding depth-finding depth-finding depth-finding depth-find It's clear from the stop collar and bit shank that it's not designed to drill holes where your screw heads need to be flush. I believe it would work a lot better if the depth stop's collar was about 1/4 inch longer.
These countersink bits, like many others, are adequate, but I purchased them because they include an optional collar for adjusting the countersink depth. It works as long as the screws are flush with the surface or slightly recessed (maybe 1/16"), but the collar on the countersink has almost no adjustment room. If you want to countersink a little deeper to install a plug, for example - Using the collar is not an option. It's too bad, because they could have made the collar narrower or, better yet, the countersink shaft longer, allowing for some depth adjustment. One last point - The set screws come with a hex key, but the collar does not. That would be fine if the collar didn't have a different size set screw for no apparent reason. Snappy, here's some advice: Fire your design engineer and replace him with someone who knows what they're doing.
These are high-end instruments. The only thing I didn't care for was how sharp the counter was. This is where the sink portion is. When I used these, I had to be careful not to dig too deeply into my decking. If you require deep counter sinks, these are ideal; however, caution should be exercised when remodeling a deck.
The drill fits nicely in the countersink holder. These bits do a fantastic job. The drill fits snugly inside the countersink holder, but not so tightly that adjusting it will be difficult. br>You can countersink just enough for the screw head, or you can countersink deeper into the wood. This is critical to remember because some designs "force" you to countersink the head much deeper than the surface level. br>The countersink metal is extremely durable; I even tried but failed to drill one to fit a slightly larger drill.
