Mitutoyo 186-101 Radius Gauge Set, 1/32" - 1/4"
Out of stock
Mitutoyo Series 186 imperial radius gauge sets let you check the radius on a corner or a fillet by eye against a stamped leaf. The radius size is stamped on each gauge, and a locking clamp holds the leaves. Toolrooms, quality control teams, machinists and fabricators use them for quick checks of concave and convex radii on parts.
The sets run in steps of 64ths of an inch. The accuracy is ±.002". Pick 1/32" - 1/4" for small radii, or 17/64" to 33/64" in the 186-103 and 186-104 sets. Note that 186-101 holds 15 pairs with a 180° arc, while 186-103 and 186-104 hold 16 leaves with a 90° arc.
