Mitutoyo 182-225 Flexible Steel Rule 12 Inches

Product Description

The MITUTOYO 182-225 is a flexible stainless steel rule designed for layout, inspection, and measurement tasks where a rigid rule cannot conform to curved or contoured surfaces. The rule measures 12 inches (300 mm) in overall length and 1/2 inch in overall width, with a satin chrome-plated finish that reduces glare for easier reading under shop lighting. Graduations are marked in both English and metric, with inch-side divisions at 1/32 and 1/64 inch. The horizontal scale orientation and 0.020-inch thickness allow the rule to flex around workpieces without kinking. Machinists, tool-and-die technicians, sheet metal workers, and quality control inspectors are the primary users of this type of rule.

This rule suits general-purpose precision measurement in machine shops, fabrication facilities, and inspection environments. It works well for measuring inside radii, checking contoured surfaces, and taking direct readings where a stiff rule would lift off the part. The dual English and metric graduations on a single blade reduce the need to switch tools when working from drawings that mix unit systems. The satin chrome finish minimizes light reflection, which is particularly useful under fluorescent or LED shop lighting.

Key Features

• Flexible stainless steel blade conforms to curved and contoured surfaces
• Dual graduation system: 1/32 and 1/64 inch on the English side, 0.5 mm and 1.0 mm on the metric side
• Satin chrome-plated finish reduces glare and resists corrosion
• 12 inches (300 mm) overall length with 1/2-inch width for easy handling
• Horizontal scale orientation for straightforward direct reading
• No hook or magnet — clean, simple blade format for versatile use

Compatibility

Designed as a standard flexible steel rule for use in general machining, fabrication, and inspection applications where English and metric graduations are required on a single blade.

Installation Notes

No installation is required for this measuring tool. Store the rule flat or rolled loosely to avoid permanent bends or kinks in the blade. Clean with a lint-free cloth after use to prevent buildup that could obscure graduation markings. Do not use the rule as a cutting guide with a utility knife, as this can nick the graduated edge and compromise measurement accuracy.
