One does need an additional tool to use these for their intended purpose. These are solid bits and cutter heads. Unfortunately, I do not have a mortise bit holder, so was only able to analyze by a) using the drill bits independently and b) physical inspection.The drill bits are sharp and straight - as one would expect. They drill relatively clean holes even though they don't need to, and the blades on the mortise part are sharp and neat. I'll be getting a mortise holder tool soon, and can't wait to use these to their full purpose.

Need special attachment for this so don't forget to buy that if you don't have. Works OK. Did not work well with my drill press which defeated the purpose.

These bits can be used only if you have the proper collar (see picture #1), speed control & chisel holder that fits your drill press or corded drill. A mortising press would be optimum. When used on corded drills controlling the cut depth is difficult at best. I set up two (2) of the chisel sets & cut some test holes. The core bits could be sharper as if you just pull the head down the core bit gets “very” hot. For this set I had to pull down the head multiple times and allow the chip removal to catch up. I do recommend that you set your plunge depth (experience) on your press before the first pass. The holes produced are in fact square and relatively clean cut. Actually got some tear out on red oak. Using a table hold down is a critical safety process that should be used with these bits as the chisels got hung up in the wood (both pine & red oak). Overall the bits are adequate to do the job after you obtain the other accessories needed. There were no directions for use in the box!

These worked well on softer wood but struggled on hardwood and had some tear out. They can be used in a pinch on hard woods but would recommend using a chisel for finishing. You need the proper drill to use these but you can do it manually as well (just takes a lot longer).

This review is for: WYNNsky Hole Mortise Chisel Drill Bit Tools, Size 1/4’’ 5/16’’ 3/8’’ 1/2’’ 9/16’’ 5/8’’This is a mortise drilling kit. If you don't know what that is you might want to back away. As a wood worker there are many times that this can come in handy. Especially if you are making trinkets and the like. Adding square walnut pegs to a maple jewelry box can really make it stand out and beautify it.First things first. If you don't know or haven't made mortises before then don't just grab these thinking you can slap them on your drill-press and presto. You need a mortise attachment kit for your drill press (see the above picture). That green thing that the mortise drill/chisel is attached to is needed. Or a mortising machine. Either one will work. Be very aware that there are limits. I have a small bench drill press by Craftsman. The attachment requires that you remove the depth stop and fully lower the table. Only then could I add the Mortising bits and secure the chuck/drill shank.The mortising bits are decent. They are not the sharpest I have ever used but they do the job. You get 6 sizes 1/4 - 5/8 in the set which is pretty awesome. I thought it odd that they skip 7/16 but whatever. There was quite a bit of squealing until I got it all lined up. I highly recommend you give your mortising bits a good squirt of silicone lube before using them to reduce friction and after you clean them up to prevent debris from making life difficult.In the pics above you can see that I only used 3. That is because it can be tedious to set each up to ensure smooth operation. The sample board did get stuck on the chisels but just a light tap with a mallet popped them off. The chisels themselves had some excessive milling marks on the ends. The result was a little bit of a burr that may have snagged the wood somewhat. The largest (5/8) had trouble attaching to my drill chuck. The reason is because the larger the auger the chuck teeth recess further 'upwards'. Meaning I could only get a 1/8 inch bite on the very end of the auger. This is not a problem with the product just with my available equipment.All in all if your on a budget and you have the drill press attachment (or even better access to a mortising machine) then I would highly recommend this product. If you have never performed mortise work I recommend you do due diligence and research your options.And remember you can always remove the auger bits, use a regular drill bit to make the hole, and then use a hammer/mallet to the square chisels to make your mortise holes by hand. If that is your plan then kudos to you.
