Mitutoyo 314-361-30 Electronic V Anvil Micrometer

Product Description

The MITUTOYO 314-361-30 is an electronic V anvil micrometer engineered for precision measurement of three-flute cutting tools such as end mills, reamers, and drills. It covers a measurement range of 0.05 to 0.6 inches with a resolution of 0.0001 inch and accuracy up to 4 micrometers, making it a reliable instrument for tool inspection in machine shops and precision manufacturing environments. The carbide-tipped anvil and spindle provide durability against wear during repeated use. A ratchet stop thimble ensures consistent measuring force across readings. Built-in data output allows direct connection to a data collection system or SPC software for in-process quality control. Licensed metrologists, toolroom machinists, and quality technicians are the primary users of this instrument.

The 314-361-30 is suited for measuring three-flute rotary cutting tools where a standard two-anvil micrometer cannot contact opposing flute faces simultaneously. The V anvil geometry cradles the tool while the spindle contacts the third flute, giving an accurate outside diameter reading. This instrument fits into precision toolroom, grinding department, and incoming inspection workflows where tight tolerances on tool geometry must be verified before or after regrinding. Its electronic readout supports fast, repeatable measurements in production environments.

Key Features

• Measurement range of 0.05 to 0.6 inches for three-flute cutting tools
• Resolution of 0.0001 inch with accuracy up to 4 micrometers
• Carbide anvil and spindle material for extended wear resistance
• Ratchet stop thimble delivers consistent measuring force
• Data output port for SPC and quality data collection integration
• Satin chrome finish reduces glare and resists corrosion
• Includes battery, box, key, and setting standard

Compatibility

Designed for measurement of three-flute rotary cutting tools within the 0.05 to 0.6 inch outside diameter range. Confirm flute count and tool diameter range before use, as V anvil micrometers are geometry-specific.

Installation Notes

This instrument requires no installation in a system; it is a handheld precision measuring tool. Before use, verify calibration using the included setting standard and zero the display accordingly. Keep the measuring faces clean and free of chips or coolant residue before each measurement. Store in the provided case when not in use to protect the carbide faces and electronic components.
