Desgarrador MicroJIG GRR

The GRR-Ripper is a push block that grips the workpiece from above and from the side simultaneously using adjustable rubber-padded legs. This three-dimensional grip keeps the stock flat on the table and tight against the fence while moving it through the blade, providing much safer control than a standard push stick.

Yes, for most ripping operations. A push stick only contacts the trailing end of the workpiece, offering no lateral control. The GRR-Ripper holds the stock vertically, laterally, and longitudinally during the cut, reducing the chance of the workpiece tipping or wandering into the blade.

Yes. The GRR-Ripper's gripping design works effectively on router tables for edge-profiling and groove-cutting operations where standard push blocks can't maintain consistent downward and lateral pressure simultaneously. It is widely used as a push block on router tables by professional woodworkers.

With the standard GRR-Ripper, narrow rips down to about 1¼" can be handled safely. Adding the 1/8" Thin Stock Accessory extends that capability to strips as narrow as ⅛", which is far below what most standard push blocks can manage safely.

The Gravity Heel Kit attaches to the rear of the GRR-Ripper and adds a trailing heel that contacts the back of the workpiece at the end of the cut. This prevents the workpiece from dropping or twisting as it clears the blade, improving safety and cut quality on through-cuts.

Yes. The GRR-Ripper is suitable for band saw use when ripping stock or cutting curves where top-down grip improves control. Its low-profile design fits under most band saw blade guards and provides lateral support not available with a standard push stick.

Beyond push blocks, Infinity Tools carries Magswitch magnetic featherboards that hold stock against the fence during ripping. Browse Shop Essentials for hearing protection and other safety-related shop products.

Yes. The GRR-Ripper system is modular—the Gravity Heel, Handle Bridge, Deflector Connector, and thin-stock accessories all attach to the main body. Multiple accessories can be combined for operations that require extended reach, different height clearances, or trailing-end control.

The Infinity Tools learning center covers table saw safety, ripping technique, and proper push block use. Learning correct technique with tools like the GRR-Ripper is as important as having the right equipment.
