High-accuracy depth gauge 7004 series

Description
The Combination Depth and Angle Gauges Set is a precision layout and inspection tool intended for machinists, inspectors and engineers. It enables depth measurement in confined spaces and angle verification for countersinks, bevels and tool bit grinds using a compact, hardened head and rigid rule.

Key features

• Precision angle verification: head with high-visibility etched protractor markings for 30°, 45° and 60°; can be set and locked to check bevels, chamfers or tool grinds.
• Versatile depth measurement: 6" hardened and tempered steel rule with deeply etched, quick-reading markings; 7/32" width provides rigidity for slots while allowing access to tighter spaces.
• Narrow bore capability: 3/32" non-graduated steel rod for measuring holes and recesses too narrow for a standard rule; measurement can be transferred to a micrometer or caliper.
• Clearance recess design: centre cut-out allows the rule to sit flush against the reference surface for more accurate readings and unobstructed view of the scale.
• Industrial durability: head and rule manufactured from hardened and tempered steel to resist wear in shop environments.

Variants / Options

• Lengths: 6" Rule / 6"/150mm Rule / 150mm Rule.
• Graduations: 32nds one side / 64ths on reverse; 32nds one side / 0.5mm on reverse; mm one side / 0.5mm on reverse.

• Gage head with protractor markings (30°, 45°, 60°)
• 6" hardened and tempered steel rule, deeply etched markings (rule width: 7/32")
