The WILLIAMS COMFORT PRODUCTS C-20-TH is a cold chisel with a 5/8-inch cutting edge, designed for heavy-duty cutting, chipping, and shaping of metal, masonry, and similar materials. Cold chisels are a standard hand tool in mechanical, plumbing, and general trade work, used wherever a driven cutting edge is needed to sever fasteners, break out material, or clean up rough surfaces. The C-20-TH weighs 0.33 pounds, making it a compact, single-handed tool suited for close-quarters work. Trades professionals and skilled DIYers keep cold chisels on hand as an essential part of any complete hand-tool kit.
The C-20-TH is appropriate for use in residential and commercial maintenance, service, and repair settings. It is commonly used by plumbers, HVAC technicians, electricians, and general maintenance trades for cutting through corroded fasteners, removing seized components, breaking out tile or masonry, and preparing surfaces for repair or retrofit work. The 5/8-inch blade width suits it to moderate cutting tasks where a narrower profile is needed for precision strikes.
Designed as a general-purpose cold chisel compatible with standard hammer-driven hand-tool applications across mechanical, plumbing, electrical, and maintenance trades.
Cold chisels are driven with a ball-peen or club hammer and should never be struck with a claw hammer. Always wear appropriate eye protection when using a cold chisel, as struck material can produce sharp fragments. Inspect the chisel head before each use and discard if mushrooming is present on the strike face. This tool does not require power disconnect procedures but should be used in accordance with applicable jobsite safety standards.
