Starrett 67094 Blade Micrometer 6 to 7 Inches Mechanical

Product Description

The STARRETT 67094 is a mechanical blade micrometer designed for measuring in slots, grooves, keyways, and other narrow or hard-to-reach features where a standard anvil micrometer cannot fit. It covers a measurement range of 6 to 7 inches with a graduation of 0.001 inches, providing the resolution required for precision layout and inspection work. The 0.03-inch blade thickness allows entry into tight spaces, and the speeder thimble enables fast spindle travel for quicker setup. The satin chrome finish reduces glare and resists corrosion. This tool is used by machinists, tool-and-die makers, and quality control technicians working with precision metalwork.

The STARRETT 67094 is suited for shop-floor and inspection-room applications in manufacturing, tool-and-die, and general metalworking environments. It is particularly effective when measuring wall thickness, slot width, or recessed features in the 6-to-7-inch range where conventional outside micrometers cannot reach the measuring faces into position. The included wrench supports proper spindle lock operation. A non-rotating spindle design prevents part marking or rotation during measurement, which is important when working with finished or lapped surfaces.

Key Features

• Measurement range of 6 to 7 inches with 0.001-inch graduation for precise readings
• 0.03-inch blade thickness for access to narrow slots, grooves, and keyways
• Speeder thimble allows quick spindle advancement for faster measurement cycles
• Non-rotating spindle prevents surface marking on finished workpieces
• Satin chrome finish reduces glare and provides corrosion resistance
• Steel anvil and steel spindle construction for durability and long service life
• Includes a wrench for spindle lock adjustment

Compatibility

Designed as a direct-use precision measuring instrument for machinists and quality technicians requiring blade-style micrometer coverage in the 6-to-7-inch range. No additional adapters or accessories are required for standard use.

Installation Notes

Blade micrometers require no installation but should be handled and stored in accordance with standard metrology practices. Before use, clean the measuring faces and verify the zero calibration at the 6-inch reference point using the included wrench and a known standard. Avoid dropping or impacting the instrument, as this can affect calibration. Consult your facility calibration procedures for recalibration intervals.
