Description

Insize 2421 Split Type Dial Bore Gauge Sets

Small bore diameters call for a gauge that can get in and register an accurate reading without disturbing the part. The Insize 2421 Split Type Dial Bore Gauge Set uses split-type contact points across a series of interchangeable measuring points, giving machinists and inspectors precise coverage of small internal diameters that standard bore gauges can't reach.

 

Key Features

  • Split-type contact points provide accurate, self-centering contact inside small bores
  • Multiple interchangeable points included, each covering a narrow measuring band for precise coverage across the set's full range
  • Hard chromed point material resists wear from repeated use
  • Tight accuracy and repeatability for reliable readings even at very small diameters
  • Compact measuring depth and overall length suited for shallow-bore and small-part inspection
  • Compatible with dial or digital indicators (sold separately) for flexible readout options
  • Setting rings available as an optional accessory for zeroing the gauge before use
