Product Description: Precision Telescopic Gauge 8–150mm Micrometer Internal Gauge for Hole Measurement This industrial-grade high-precision telescopic gauge is a professional measuring tool for scenarios such as machining, mold manufacturing and equipment maintenance. It features three core advantages: accurate distance measurement, flexible telescoping, and portability with durability. It can quickly measure dimensions that are difficult to access with conventional measuring tools, including inner holes, grooves, steps and deep cavities. Suitable for the high-precision measurement needs of mechanical engineers, mold technicians and quality inspectors, it provides reliable data support for industrial production and testing. Product Parameters: Material Stainless steel. Color Silver. Size 1cm*15cm*12cm Weight 0.3kg Logo Imprint Laser engraved / Transfer printing / Sticker Application Scenarios: Machining Scenario: Measure the inner hole diameter, part groove width, and step height processed by lathes, providing data support for machining accuracy control. Mold Manufacturing Scenario: Inspect mold cavity dimensions, core clearance, and slider fitting tolerances to ensure mold assembly accuracy and product molding quality. Equipment Maintenance Scenario: Measure the inner diameter of equipment bearing seats, the wear amount of hydraulic cylinder inner walls, and the inner hole dimensions of gearboxes to determine whether equipment components need replacement. Quality Inspection & Acceptance Scenario: Conduct random inspections on the inner hole, groove and other dimensions of incoming parts to ensure that the parts meet the tolerance requirements specified in the drawings.
