These instructions are a complete step by step guide that will show you how to build an angle grinder chop saw using a $15 Harbor Freight angle grinder (item #69645, to be specific). With the grinder included, it’ll probably cost you around $25 total!

This project is designed to be an EASY build. You can probably get most of it done in a couple of sessions. The most time consuming part will be waiting for epoxy and polyurethane to dry!

About the plans:

  • Formatted for normal sized (8.5″ x 11″) printer paper, so you can print them at home.
  • Includes Metric AND Imperial (U.S.) Version.
  • They include:
    • A complete shopping list for the materials you need.
    • A complete list of parts you need to cut with all the dimensions necessary (with images).
    • Step by step instructions that accompany and compliment the build video.

About the Disc Sander:

  • Dimensions: 11″ long x 10″ wide x 9″ tall.
  • Uses a Drill Master angle grinder from Harbor Freight (not included).

Tools required (or at least strongly suggested) to build this project:

  • Table Saw
  • Miter Saw (Recommended, but not necessary if you have a table saw sled or another way to make good cross cuts)
  • 23 Gauge Pin Nailer (Recommended, but not strictly necessary)
  • Drill
  • Drill Press (Recommended, but you could get by with a regular drill)
    • 5/64″ or 1/16″ (1.5-2.5mm) bit
    • 7/8″ (22mm) Spade or Forstner Bit
    • 1/8″ (3.2mm)
    • 1/4″ (6-6.5mm)
    • 5/8″ Bit (16mm)
    • 5/16″ Bit (8mm)

    Another superbly engineered project from Tommy that is a great addition to my shop. You see a lot of how to videos on You Tube but none of them want to give or sell you the plans. I love Tommy’s videos because you can understand what he is doing because of his voice over work which is a big help. He is always available to help you if you run into a snag.

    Very good project. Am woodworker and this was my first Harbor Freight purchase. Had coupons so bought two grinders. Take screws off transmission housing. Remove and discard cheap grease. Replace with good hi temperature grease.
    There are grinder blades (3 tooth) made for wood cutting. In addition to metal cutting, am going to experiment with design as micro chop saw in addition to regular miter saw.
    Fun to build, but think about a little larger size for your other angle grinders.

    I had a lot of fun building this tool. The instructions are clear and concise. Highly recommended!

    What a great idea! Thanks for the plans for the cut off saw. Had a ball building it and used it straight away on another project. I had no trouble following the instructions.

    I just got the plans for the angle grinder / chop saw. How great to have all the accurate
    measurments and a full and complete cut list too. Wow , somebody put a lot of thought and effort in these plans. The accuracy of the CADD drawings is an absolute joy to read and follow. I wish my Blueprint classes were this easy to follow.
    Bravo Tommy, very excellent plans. I will be ordering more plans from you soon.

    Sincerely, Jim H

    Excellent and easy to follow instructions. I am half way through and will let you know how I get on. One glitch is that my grinder (Bosch) has angled handles which required a little adjustment. I overcame the problem by using a steel strip, drilling to connect to the grinder, and then screwing to the plywood base with packing to the underside of the tool. Works well and am making progress. Should be great when finished.
    Incidentally can you name the tool used to measure the positioning of the elements. it seems to have a sliding central bar? I just wonder whether I can get one in the UK. Thanks again.
