What people are saying:

"Save your fingers Get a GRR-RIPPER" - Workbench Magazine

"GRR-RIPPER is an indigenous device which I believe will find many uses in the woodworking workshop." - Australian Woodworker

Product Description:

GRR-RIPPER Advanced comes with 3 legs featuring proprietary Green GRR-RIP® non-slip material, built-in balance support, adjustable handle, and includes two additional accessories: Stabilizing Plate, Adjustable Spacer.

The GRR-RIPPER Advanced gives you the three essential forces of control you need when working on a table saw:

1) Downward Pressure: Keeps the material firmly on the tabletop and virtually eliminates kickback

2) Inward Pressure: Keeps the material gliding against the fence preventing wood drifting, burning, and binding

3) Forward Pressure: Feeds both the keeper and offcut of your cut with speed and accuracy parallel to the blade and fence 

The result is cleaner, incredibly precise cuts with your hands protected and keeping the wood under control throughout the cut.

Don't use a table saw without it. Work safer.



Cut with Surgical Precision with the 1/4" Leg and rip down to 1/4" on your Table Saw. With the optional 1/8" Leg, you can cut down to an impressive 1/8" for outstanding detail.

The powerful grip gives you unmatched control and holds over a variety of materials such as cherry, maple, walnut, poplar, purple heart, aluminum, plastics, and the list goes on. Save money on scrap and expensive exotic woods.

The GRR-RIPPER Advanced comes with two additional accessories for extreme versatility and precision in your shop: 

Stabilizing Plate locks the material against the fence keeping your work square and flush. It provides 250% more stabilizing surface to keep your work under control when resawing on the table saw or routing on the router table.

Adjustable Spacer gives you 54% more gripping surface and 1" of additional cut capacity to take on your biggest projects and wider cuts.

Essential precision, safety, and control for any table saw, router table, jointer, and band saw. 

Made in the USA. A true MICROJIG Innovation.

What Customers Are Saying:

"I have used it on the table saw, re-sawing on my band saw, on my router table, my shaper, and my edge plane and have found it to be a tremendous help. I am in my 60's and not as agile as I was 30 years ago. Would like to keep all my fingers till the end." - Dr. V (5-Star Amazon Review)

    "It completely protects the hand while giving great control over whatever you're cutting. With the grippers on both side of the blade, there's no concern at all about a kickback." - crsangel (5-Star Amazon Review)

      "The first praise I can give is that I still have all the fingers. I find this tool to be well thought out and very useful. I use it mainly on a table saw, but it would work well with any tool that cuts long narrow pieces of wood and there is a danger of injury. Router, jointer etc." - Paul Edgar (5-Star Amazon Review) 

        "I freaking love this thing. It saved my project, and my sanity." - Alex Smith (5-Star Amazon Review)

          "I am always on the lookout for devices that will help me increase my safety margin...and the Gripper does that and more. I liked it so much that I bought a second, which allows me to rip longer pieces by leapfrogging Grippers." - Scuba Steve (5-Star Amazon Review)
