The Stanley FatMax 0-16-266 is a 40mm bevel edge chisel from the Thru Tang range, the widest size in the series and the one used for heavy waste removal and large-scale joinery work. The 40mm blade clears timber quickly when chopping wide mortises, fitting large hinges to fire doors, and cleaning up housing joints in floor joists and stud partitions.

At this width the Thru Tang construction is critical. The steel tang passes through the entire handle to an integrated strike cap, distributing the force of heavy mallet blows evenly rather than concentrating stress at the handle-to-blade junction. This prevents the splitting and loosening that ends the useful life of chisels built with a socket or short tang design.

The chrome vanadium steel blade is hardened and tempered to maintain its cutting edge through sustained use on softwood framing and hardwood trim. The wider blade acts as its own reference surface for paring, and the bevel grind gives clean, controlled cuts when working to a scribed line.

The FatMax bi-material handle is sized to match the wider blade, providing a comfortable grip for the two-handed striking technique needed to drive a 40mm blade through dense material. The softer grip zone reduces vibration fatigue during extended chopping sessions, while the harder core keeps the handle rigid under load.
