MAIRCO CHISEL ROUND 12"
The query refers to the Mairco 12" Round Chisel, a heavy-duty cold chisel with a round (hexagonal or octagonal) shank from the Mairco brand, known for its budget-friendly hand tools in construction, demolition, and metalworking. This model is likely a variant of Mairco's standard cold chisel series (similar to their 550g, 650g, or 1kg flat-edge chisels), featuring a round shank for secure hammer striking and a 12-inch length for extended reach in cutting, scoring, or breaking materials like concrete, stone, brick, or metal. It's popular in Southeast Asian markets for professional masonry or DIY renovations, where the round shank provides better grip and reduced slippage compared to flat designs.

Features and Uses
- Round Shank Design: Hexagonal or octagonal round profile ensures stable, non-slip engagement with hammer strikes; ideal for high-impact tasks without the tool twisting.
- Durable Blade: Heat-treated high-carbon steel resists chipping and dulling; flat edge excels at scoring lines, cutting bolts/rivets, or removing mortar/grout in brickwork or tile jobs.
- Extended Reach: 12-inch length allows access to deeper or confined areas, such as in demolition, stone carving, or metal fabrication, while maintaining control.
- Versatile Applications: Suited for medium-to-heavy demolition, plumbing repairs, automotive work, or general construction; not for woodworking (use dedicated wood chisels instead).
- Safety and Reliability: Built for daily professional use; always employ eye protection, gloves, and a striker's guard to mitigate rebound risks.
