Industrial-Grade Inside/Outside Calipers – Precision Forged Steel Measurement Tools for Machining, Metalworking & Quality Control

Key Features

• Dual-Function Design: Measures internal bores (ID) and external diameters (OD) with one tool – ideal for pipes, shafts, and complex components.

• Heavy-Duty Forged Steel: Heat-treated carbon steel resists deformation during repeated use in foundries, machine shops, or construction sites.

• Precision-Ground Tips: Tungsten carbide contact points maintain ±0.05mm accuracy for critical tolerance checks.

• Friction-Joint Adjustment: Smooth-tension knuckle holds settings securely without slipping, even under vibration.

• Corrosion-Resistant Finish: Black oxide coating protects against rust, coolants, and workshop chemicals.

Product Description

Engineered for machinists and quality inspectors, Industrial Inside/Outside Calipers deliver uncompromising accuracy in harsh environments. The forged steel frame withstands impact during layout work or forging inspections, while the reversible legs switch instantly between ID measurements and OD checks.

The knurled friction joint allows single-handed adjustments, and the carbide-tipped jaws resist wear when scraping against cast iron or stainless steel. Unlike digital calipers, these mechanical tools excel in high-temperature, magnetic, or dirty conditions where electronics fail – making them essential for automotive, shipbuilding, and heavy equipment maintenance.
