Conical Bore Gauge M318.045 — 1–6.5 mm, 1:10 taper

The Conical Bore Gauge M318.045 is a compact, precision inspection tool for measuring small cylindrical bores from 1 to 6.5 mm, designed for workshop and inspection use.

• Compact 1–6.5 mm measuring range
• 0.1 mm graduation for clear readings
• 1:10 conical taper for centred seating
• Matt-chrome steel cone with anodised handle

Precision that fits the smallest bores

The gauge is engineered for reliable checks in the micro range, where compactness and repeatable contact geometry matter. The 1–6.5 mm measuring range places this instrument among tools for fine mechanical and micro‑component inspection, offering an alternative to larger plug gauges when access and handling are constrained. With a 0.1 mm reading the design emphasises fast, unambiguous indication of bore size, reducing interpretation time during routine checks. The compact overall length and light weight help to keep operator fatigue low while ensuring consistent positioning for repeat measurements.

Durable construction for repeatable inspection

A matt‑chrome steel cone provides abrasion resistance and a smooth contact surface, while the anodised aluminium handle combines low weight with comfortable handling. The 1:10 taper gives a defined seating profile that centres the instrument in cylindrical bores, improving repeatability compared with blunt probes. The 65 mm cone length and 122 mm overall length deliver sufficient engagement depth for typical small‑bore components without compromising manoeuvrability. These material choices translate into a tool that withstands daily workshop use and contributes to consistent quality control results.

Practical workflow and application benefits

The instrument is intended for rapid inspection of cylindrical bores where quick go/no‑go orientation or nominal size checking is required. Its compact form factor and clear graduation speed up throughput on benches and in inspection stations. For assemblies with many small bores, the gauge reduces cycle time by simplifying the seating and reading steps. The low mass aids handheld use, while the precise taper geometry supports reproducible seating across repeated measurements — an advantage for serial inspection tasks in production or maintenance environments.
