Side by Side Comparison of: Delta vs WoodRiver

This accessory allowed me extreme versatility installing mortises in a hard maple piece at an angle that was out of square.

Worked great with my Rybi drill stand and has accommodation for other drill sizes. Very happy with its performance & recommend it

Very nice. Had a bit of trouble attaching it but realized it was my misunderstanding.

Had to modify the cast collar to fit my older craftsman drill press but after that it worked great

Just got it and it fits my Steel City 20530 17" dril press beautifully! Bolted right on including the fence. Haven't used it yet but wanted to know.

excellent !!! just what I was looking for. Thank you

For those of us who don't want to chisel by hand but don't have the money or room for a dedicated chiseling machine, this is a really good tool. The one thing I would stress to everyone is follow the directions. I didn't at first and couldn't figure out why the chisel wouldn't push through the wood. The only two negative things I can say are that the finish wasn't the same as the picture (which I really couldn't care less about) and sliding the rings over my chuck to get to the quill was almost impossible. Now that they're in place though I don't think I'm ever going to get two of the adjustment rings off again. They're not affecting the function of the drill press so I don't think it matters either.This thing makes fairly clean cuts. It only takes about 30 seconds to clean out the very bottom corners. Haven't found anything negative about it. Hoping it stays that way.

Does the job. I think the chisels could be better. Some of the mortises i've cut were a little ragged. But, i would buy it again.

It appears to be well built, but it will not fit any of the Craftsman drill presses currently available at Sears. I went over there and tried out the collars on all of the drill presses just to make sure.The Craftsman products listed in the description have been discontinued for about 15 years. Also, do not buy this product if you have less than a 12 in drill press. It will be too long.

Purchased this item for my Powermatic 2800 drill press, I needed a tilting mortising machine. This product for its price point (only $99) is well made, instructions are clear and packaged nicely. Comes will a fitted plastic case for storage. The hollow chisel bits are not of the best quality nor polished to any meaningful degree, it is a trade off for the money spent. I will look for a better quality hollow chisel bits as well as a one inch hollow chisel bit. I have a HF hollow chisel machine that I will give away or have my scrap metal guy come and get it; money not well spent, buy cheap, buy twice or more!

it works just like it should. I have only set it up, to make sure every thing fit like it should and tried it out only. I have a furniture project I am starting to plan out now. coffee table and 2 end tables, so I will see just how it works out.

The Mortising attachment works fine. The operator does need to be accurate with his/her positioning of the wood. The rating would have been five stars, except that the included directions to attach to a drill press could be more explicit. There is a set of directions available on the Delta web site that explain the set-up in greater detail.

needed better directions. had to work with it to get it to function the way it should.

The hold down rod did not fit into the fence. It seems like the hole was never milled out after casting. Otherwise everything is solidly made, heavy castings all on parts. Chisels seem sharp enough but I doubt they would have lasted very long in dense woods.I wanted to like this very much but it just simply did not work for me. The amount of effort involved in getting this on (requires I remove the depth gauge/stop from the press before clamping on the chisel holder) negated the benefits. If I required production quantities of mortises to be made then I can see how the lengthy setup would be worth it, but if I were a production shop I would just invest in a real mortiser.

Well made but did not fit my drill press.

It is better than a kick in the shins and seems to work fairly well after I worked on the fit between the main casting and the lower stop on the quill of my drill press. My measurement was 66 mm but their casting had a lot of paint on it. I used a rotary sanding unit in the drill press to remove paint but also had to remove a slight amount of metal. After applying a little silicone it now fits fine.

Tightening lever's groves stripped out on first use; metal of the lever itself is too soft do do the job. Otherwise, the tool did what it was designed to do.

while functional and relatively easy to set up i found the quality poor. The face you clamp your work to looks like it was finsihed with a angle grinder leaving a surface with ridges that will damage any finished surface clamped to it. The hold down clamp is poorly designed and is unusable for any tall stock. Essentially it is cheaply made, but with modification, time, and effort you can make a functional mortiser out of a good drill press.

Great in theory, but just like I was warned, this mortise attachment couldn't perform. There is no good way to mount this firmly enough to any drill press well enough to mortise anything harder than pine. Slip after slip, adjustment after adjustment, this thing is destined to fail. I'm only giving it two stars because I can still use the base/fence for other drill press uses and the chisels are decent.

For starters, no combination of the collars would fit snugly on my drill press; I had to use some pipe clamp to fill in the gap. This was really surprising and frustrating (there are so MANY included collars, I really thought one would fit!).So I finally get setup, I grab my "test" piece of scrap. Clamp it down (btw the table is WAY too short! I could only use one of the clamp arms) and start to drill. At the point where I felt I was forcing things I started to back off, and the entire piece of wood came up with the cutter. ALL the clamps failed: the "hold fasts", the guide, AND the lock holding the chisel in place! Four different failures, all on the first cut. No thanks! Returned immediately.

This tool was supposed to be new. This is not E bay the case was filthy the large bit showed chuck marks on it the factory wrap was torn and messed up and the parts had several paint chips. what is going on?

missing 1/2 of the thickest collar, can't use it.

Overall, I wish that I had applied the purchase price of this drill press attachment to the purchase of a stand-alone mortising machine.When mine arrived I was disappointed with the fit and finish. The unit that holds the work piece is made from cast iron. Unfortunately, only one face had been machined smooth. The supplied bolts would not slide the length of the slots in the cast iron work piece holder. I took the unit to my local machine shop to have work piece holder re-machined. That added almost $50.00 to the purchase price. The photo of the product shows a nicely painted assembly - mine was unpainted cast iron.In use I needed almost every C-clamp I owned to hold it firmly to my drill press - in addition to the supplied hold down hardware. Aligning the cutter to be square with the edge of the work piece is almost impossible.

The product it not manufactured for precision. You will definitely shorten the life of your drill press. The chisels themselves are razor sharp though. Im going back to the old school way to mortise and tenon

Attachments did not fit my Ryobi 10in Drill press (UNIVERSAL???)

Terrible finish, the chisels are dull and will not cut in hardwood.I cannot possibly recommend this item.

This kit only uses 5/8" shank chisels. You can not get replacements or different sizes. Normal Mortising chisels are 3/4" shank. I would return it if I had the box.

This is a COMPLETE waste of money. DO NOT BUY this product. It does not work. The bits slide right through the chisel and it will not do what the product is intended to do. I wish I had done more research on the product before I bought it. I wasted $100.00 on this and regret buying it. I tried to use it on cherry and it didn't work. Even got a piece of pine out and it wouldn't work with pine either. I want my money back.

Looks like it was made in a third world country. Covered in a black, greasy protectant and when cleaned off, was just a rusty casting. Just very poor workmanship, not what I would have expected from Delta. Thumb screw holes were crooked and off center and finished off very little. It could have, at least, been painted Delta grey. It is not at all as pictured. All the parts are there, but that's where the similarity stops. I realize that it's not a commercial product, but really? For $100 + I expected something better. It worked as intended, but is a real piece of scrap. I probably would have been better off buying a Grizzly product!

I ordered this to go on my Delta drill press. The purchasing process was easy. It shipped quickly. It arrived with stripped threads on the collar that goes around the drill so it won't tighten down, so it can't be used.
