Best Product Lines
Vise-Grip locking pliers are the defining product — these are the original locking pliers invented by William Petersen in 1924 and remain the industry standard. Irwin Marples chisels are trusted by professional woodworkers. The Quick-Grip clamp series is a job site staple. Irwin hole saws and twist drill bits are well-regarded for cutting performance.
Who Uses Irwin Tools
General contractors, plumbers (for Vise-Grips), woodworkers (for Marples chisels and clamps), and any professional who needs reliable clamping and cutting tools.
Buying Used Irwin Tools
Irwin Vise-Grips are excellent used — the mechanism holds up through decades of use. Check the adjustment screw and jaw teeth. Marples chisels are outstanding used purchases; the steel takes and holds an edge well. Quick-Grip clamps should be checked for smooth sliding and firm clamping.
