    Worked great on my first project!
    5/ 5stars

    Bought this to make mortise joints on a bed project and it worked great! Bed is already being used by our son.

    This product does not fit "just about any drill press" as stated. Do not buy this unless you have one of the drill presses listed.

    Mortised child's bank
    5/ 5stars

    With limited instructions it was. Easy to install and use. Not a lot of time wasted putting it on and off drill press. Instruction were better than others but was lacking. I have a jet which it handles but nothing written that made it easy. Overall works great

    5/ 5stars

    I bought this about 2 month ago and have used it twice and the product works great. I took a few tries to get it setup the first time, but after I figured it out it work great. It is imporant to keep the tip of the drill bit oiled so it does not over heat.

    5/ 5stars

    This mortising attachment kit did the job I had to do but I have to say it is a low quality version of what it can be.
    Certainly not the best.

    Mortising jig
    5/ 5stars

    I've been very happy with the unit overall, but I am having a great deal of difficulty with the 3/4" drill and/or mortising bit. They seem to overheat, no matter how often I withdraw and reinsert the drill.. The smaller bits presented no such problem.

    Drill press is awesome and very well made
    5/ 5stars

    Bought this a month ago and have loved drilling and using the mortis attachment. Great product.
