Popular RST Bolsters & Cold Chisels

The RST range at Tooled-Up encompasses various chisel types designed for specific applications. Bolster chisels, typically available in widths from 75mm to 100mm or more, excel at brick cutting, block splitting, and mortar removal. These wide-bladed tools distribute force effectively across masonry materials, making clean cuts with minimal material wastage. Professional bricklayers particularly value the balance between blade width and overall weight that RST achieves in their bolster designs.

Cold chisels from RST come in various lengths and point styles to suit different metalworking applications. Standard cold chisels with flat cutting edges handle general cutting and shearing tasks, whilst specialist variants include diamond point chisels for starting holes and creating indentations, and cape chisels for cutting keyways and grooves. The compact sizes prove invaluable for automotive and machinery maintenance, where access constraints demand shorter tools, whilst longer patterns provide the reach necessary for construction and fabrication work.

Multi-piece chisel sets represent excellent value for tradespeople establishing their tool collections or expanding their striking tool capabilities. These curated selections typically include the most commonly required sizes and patterns, packaged together at advantageous pricing compared to purchasing individual tools separately.

Safety and Compliance

When using RST bolsters and cold chisels, adherence to proper safety protocols protects both the operator and those working nearby. Always wear appropriate personal protective equipment including safety glasses or a full face shield to guard against flying debris, which represents the primary hazard when striking chisels. Heavy-duty work gloves provide protection from sharp edges and reduce vibration transmitted to the hands during extended use.

Inspect chisels before each use, checking for mushroomed striking heads, which should be ground back to their original profile to prevent dangerous metal fragments breaking away during use. Similarly, examine cutting edges for chips or cracks that could propagate during striking, potentially causing tool failure. Replace or repair damaged tools promptly—never continue using compromised striking tools.

Select hammers of appropriate weight and type for the chisel being used. Ball pein hammers or club hammers typically pair well with cold chisels and bolsters, providing sufficient mass for effective cutting without excessive force that might damage the tool. Ensure secure workpiece positioning before striking, and maintain awareness of the chisel's cutting direction to avoid injury to hands or body parts. When working with masonry, consider dust control measures in accordance with HSE guidance on silica exposure, particularly during prolonged chiselling operations in enclosed spaces.

Frequently Asked Questions

What's the difference between RST bolsters and cold chisels?

Bolsters feature wide, flat blades typically 75mm or wider, designed specifically for cutting and splitting masonry materials like bricks, blocks, and paving. Cold chisels have narrower blades intended for cutting metal, including steel, aluminium, and copper. Whilst both are striking tools, their geometry and heat treatment are optimised for their respective materials.

How do I maintain my RST chisels?

Keep cutting edges sharp by touching them up with a bench grinder when performance diminishes, maintaining the original bevel angle. Grind back any mushrooming on striking heads to prevent dangerous metal fragments. Store chisels in a dry environment and apply a light oil coating to exposed metal surfaces to prevent corrosion. After use in masonry applications, clean off cement and mortar residue promptly.

Can RST cold chisels cut hardened steel?

RST cold chisels are designed for cutting unhardened or mild steel, along with softer metals and materials. Attempting to cut hardened steel, such as tool steel or case-hardened components, will likely damage the chisel's cutting edge. For hardened materials, specialised cutting tools or thermal cutting methods are more appropriate.

What size bolster chisel do I need for standard UK bricks?

For cutting standard UK bricks (215mm × 102.5mm × 65mm), a bolster chisel between 75mm and 100mm wide provides optimal performance. The 100mm width aligns well with brick dimensions for clean cuts, whilst 75mm bolsters offer slightly better manoeuvrability in confined spaces. Many bricklayers carry both sizes to suit different situations.

Are RST bolsters and cold chisels suitable for professional daily use?

Absolutely. RST manufactures their striking tools to professional standards, with materials and construction methods that withstand the demands of daily site work. Many UK tradespeople rely on RST chisels as their primary tools, appreciating the combination of durability, performance, and value that the brand delivers. With proper maintenance, RST chisels provide years of reliable service in professional environments.
