I just bought a 3/4 hp tall drill press from Grizzly. I was thinking about getting their mortising attachment for it. Anyone have experience with drill press mortising attachments, how well do they work and how do they compare to dedicated mortisers?

I have an ancient Delta/Milwaukee drill press with a Mortise attachment, gift from old friend. (Similar to http://lumberjocks.com/projects/44569) Works just fine.

BUT the initial setup took some effort to get everything (Chisel holder, drill chuck and drill) in alignment just so. (And if you don’t you can wind up burning a drill)

As I already had a drill press, I keep this dedicated to making square holes. My only advise would be, make sure the chisel sets you buy can be used with dedicated machine you might buy later. Also bear in mind the golden rule when buying chisles YOU GET WHAT YOU PAY FOR!!!

I bought a Delta Mortising attachment years ago for my drill press….I used it till I finally learned better….It’s a bastard to set up…..Takes too much time to adjust, plus it ties up your d.p. so you can’t use if it need be..You’ll have to tear it down everytime when you want to use the d.p. I put it in the box, and bought a Delta Mortiser, dedicated to that one task only. My d.p. is always ready to go now. I would not recommend buying one for the d.p. They are a pain in the ar%&^#@ to use. If you can get a bench mortiser, I would say get it…..and stay clear of the d.p. attachment…...

I bought one for my drill press, I think my first question on LJ was about using one and I also got mixed reviews. The set up was time consuming, the fence attachment for the table was lame, and there just wasn’t a lot of leverage on the handle. After trying to cut two holes in soft wood I put it all back in the box. A small benchtop mortiser is way better then a drill press attachment in my opinion.

It depends on how often you’re going to make mortises. I have an aged Delta floor model drill press and an AMT brand mortise attachment for it (extra points if you remember AMT). It is a PITA to set up, but once set it cuts fairly nice mortises. I just plan my work so that all my mortises get cut so I can switch the drill press back. I don’t often make pieces using mortise and tenon joinery though. If you are going to be making mortises frequently then you would probably be happier with a dedicated machine.

Just my 2¢

I have one for my Delta DP. I like well enough and use it enough to want t but not enough to justify buying a dedicated mortiser just yet. The only difficult part I’ve found with set up is setting up the fence square with the mortise chisel…most of the time I can set the piece up square by hand and don’t bother with the fence.

I have one for my Ridgid D/P and it works okay, just slow. I recently bought a HF mortiser and it works just fine. M and T are not something I do every day. If I did I would invest in a better quality dedicated mortiser.

I have the Gristly mortiser in the plastic case with 4 bits, holddowns, and such to fit every drill press known to man. It cost $49.95 + shipping 4 years ago, don’t know about now. I have used the bodiddley out of it, and am getting ready to use it again on an Eastwood chair. It works fine on my 3/4 horse bench type drill press. I’d never used one before, so I read the instructions and set it up. The holddown is like most mortisers; it doesn’t work. Toggle clamps on the table do. I bought a pair of diamond sharpening cones from Lee Valley for the hollow chisels, and I use a small file (an old ignition point file—am I dating myself?) to touch up the drills. For the money spent, it was a really good deal. If you look at the chest I built, and try to imagine how many mortises are in it, you’ll get an idea how well it works. Did them all in one day. Took another to clean up the dp area.

As little as I do mortises, I’d still go for the dedicated machine.

There are lots of ways to cut mortises and i have done most of them. I have used a mortising attachment on a drill press and I own and have used a dedicated mortising machine. I’m not a big fan of either.

My preferred way to cut a mortise is with a plunge router and I am a big fan of the Mortise Pal jig. I say this after a lot of (somewhat expensive) experimentation.

Thanks for all the replies. The Grizzly DPA costs like $65 now (inflated 50% in 4 years-what is it like medical or college tuition??); just saw Woodcraft has the Delta mortiser with a $50 rebate for $270. I don’t do a lot of mortises either, but when I do I want them right – no room for error on those joints.

I have the Delta mortiser attachment for my drill press. It’s a pain to set up, but works well once you get it adjusted correctly. I very rarely use it though – it takes longer to get it installed and tweaked than it does to use a router and clean up by hand unless you’re doing a lot of mortises.

In retrospect, I probably should have saved my $$$ for some other little used accessory.

A couple of weeks ago, I bit the bullet and got the Powermatic dedicated mortiser. I had a job to make four tables (16 legs, 32 mortises) and a really tight schedule. This was my first mortiser and – after a bit of practice – made me wonder why I hadn’t gotten one years ago. The mortises took about an hour instead of most of the day. – lol

I’ve never heard anyone rave about a drill press mortiser and after using the dedicated machine, I can’t imagine anything else.

dedicated is my vote…I’ll echo Rick D above on all counts but will double the echo on tying-up the DP…seems everytime I got mine set-up, I needed the DP for its intended use. and I never thought it cut a nice mortise either. DP table sits high and side support was a problem. On a dedicated machine, the table only sits about 3” from the bench top and easy enough to clamp scraps as support.

I picked up a new Delta “dedicated” with a 4 bit set years ago for under $300. Bits were the cheap ones but they still work.
