Natural stone and cast stone up to 8.25 inches high and 18.25 inches wide.

BUILT FOR STONE MASONS

A Stone Splitter That Pays for Itself

The Block Shear stone splitter is a hydraulic guillotine built for masons who split natural stone every day. Set the stone on the table, line up the mark, and the single hydraulic foot lever drives 40,000 lb of force through two case hardened tool steel blades. The stone breaks where you want it, with a natural rock face ready to lay.

The worktable height adjusts to the stone, so thin veneer and 8 inch wall stone both sit right under the blades. Choose the manual hydraulic model to split anywhere with no power or air, or the air-assist hydraulic model to cycle faster off a compressor on high volume jobs.

Every machine is built in Pittsburgh, PA, and the blades and frame weldment carry a one year warranty. Most users report the splitter pays for itself on the first job.

What Stone Masons Say

Fantastic cutter

March 7, 2025

45 years in business and this stone splitter is by far the best i have ever used. Built to handle any type of stone with no difficulties. Cuts stone exactly where and how you want it. I love the 18 inch wide table for shaping caps or large dry stack stones, can easily handle 8 inch thick stones. Great tool and fairly priced. Every stone mason should have one of these. Thanks so much Ray

Hands-On Experience

May 7, 2025

I was working on a stone project in Ligonier, PA and got interested in Block Shear’s manual hydraulic stone splitter after reading the many positive reviews and watching videos on their website. Since I was nearby, Ray let me come out and try it before buying. The demo was helpful, the product worked great, and the service was excellent.

This is a quality piece of heavy-duty equipment. No more time-consuming, labor-intensive splitting stone by hand. Splits large limestone and sandstone easily.

How-To Guides

Hydraulic Stone Splitter Questions

Natural stone such as limestone, sandstone and granite, plus cast stone and precast, up to 8.25″ high and 18.25″ wide.

Set the stone on the adjustable table with your mark under the upper blade, then work the hydraulic foot lever, or use the air-assist, until the stone breaks on the line.

The manual model needs no power or air and goes anywhere. The air-assist model runs off a compressor and cycles faster, which pays off on high volume splitting.

Up to 8.25″ high in an opening 18.25″ wide. For wider slabs up to 24.5″, see the Stone & Slab Splitter.
