Mitutoyo 186-907 Radius Gage Set 10 Piece 0.55-1 Inch

Product Description

The MITUTOYO 186-907 is a 10-piece radius gage set designed to measure both convex and concave radii on machined parts, fabricated components, and finished surfaces. Each leaf is stainless steel with a satin chrome finish and covers a specific radius increment from 0.55 inches through 1.0 inches in 0.05-inch steps. Accuracy is rated at 0.04 mm (0.0016 inches), making this set suitable for quality control inspection and layout work in precision fabrication environments. The set stores in a holding case with indexed pockets for quick leaf identification and protection during transport or bench storage.

This radius gage set is used in machine shops, fabrication facilities, tool rooms, and maintenance departments where radius verification is part of the inspection process. Typical applications include checking fillet radii on weldments, verifying corner radii on turned or milled parts, and confirming tool wear on cutting profiles. The set covers both convex and concave geometry with each individual leaf, eliminating the need for separate gage sets for each configuration. The compact case makes it practical for use at the machine, the inspection bench, or in the field.

Key Features

• 10 individual stainless steel leaves covering 0.55, 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95, and 1.0 inch radii
• Each leaf measures both convex and concave radii
• Accuracy of 0.04 mm (0.0016 inches) per leaf
• Satin chrome finish reduces glare and resists corrosion
• Includes holding case with indexed pockets for organized storage
• Stainless steel construction for durability in shop environments

Compatibility

Designed as a general-purpose radius gage set for use with standard inspection and layout workflows in machining, fabrication, and quality control applications.

Installation Notes

No installation is required for this hand-tool gage set. Handle leaves by the edges to avoid contaminating the gage surfaces with oils that can affect contact readings. Store leaves in the indexed case when not in use to prevent nicking or bending. Calibration verification against a known standard is recommended before use in critical inspection applications.
