Probst STS-43 Stone Splitter

The Probst STS-43 Stone Splitter and Cutter features an extra-long cutting blade designed for larger concrete blocks and similar products. This new Probst model provides increased splitting force with reduced operator effort, resulting in clean cuts on concrete blocks, breeze blocks, paving blocks, and similar materials. The STS-43 is supplied with one set of cutting blades.

Compared to the STS-33-F, the Probst STS-43 offers a longer cutting area, allowing operators to cut blocks up to 440mm in length and a maximum height of 120mm—ideal for concrete and breeze blocks.

This redesigned block and stone splitter from Probst has been engineered to cut or snap blocks easily with minimal operator force. It’s a simple, user-friendly tool that produces a clean, precisely formed edge on blocks, without generating dust, noise, or requiring water, making it safer for operators and better for the environment. Additionally, it requires minimal setup and pack-up time.

The Probst STS-43 Block Cutter is fitted with a newly designed triangular cutting blade that provides a cleaner, more accurate cut compared to the older square blade used on the discontinued Probst AL33 Block Cutter.

The Probst STS-43 Stone and Block Cutter is supplied with a tilted, rigid supporting table to ensure all blocks are cut at a consistent angle.

The Probst STS-43 Stone Splitter features a reversible, triangular-shaped cutting blade.

To speed up work significantly, the STS Probst Splitter includes a size indicator (showing both cm and inch measurements) on the cutting table, as well as a 45-degree angle indicator on both support plates.

What is a Block Splitter?

A block splitter, also known as a block cutter, stone cutter, or even guillotine, is used to cut or split small paving elements such as blocks, slabs, and stones. After splitting, the block has a clean, straight edge ready for laying in position.

Which is Better: Block Splitter or Power Saw?

This question has sparked debate among professionals for years, and opinions remain divided—about 50% prefer a manual block splitter, while the other half prefer a power saw. A power saw cuts along a marked line on the block and can take 15 seconds to a minute to cut, depending on the skill of the operator. A block cutter, on the other hand, is quicker, requiring only a few seconds, though it takes more skill to master.

Differences Between a Block Splitter and a Power Saw

The main difference when splitting paving blocks with a block splitter rather than a power saw comes down to dust and noise levels. Power saws are noisy and generate considerable dust, often requiring dust suppression equipment. A manual block splitter, however, is much quieter, and the dust produced is minimal, so no additional dust control is needed. Additionally, power saws require frequent disc changes, and their lifespan is often shorter than that of a quality block splitter, such as the Probst STS-43 Block Splitter.
