Choosing the right tool
| If you need to… | Start with | Shop |
|---|---|---|
| Check an outside diameter or length at the machine | Digital caliper, then an outside micrometer for tighter tolerance | Calipers · Micrometers |
| Measure a bore or internal diameter | Three-point internal micrometer, dial bore gage or telescoping gage | Bore & Inside Measurement |
| Check runout, flatness or alignment | Dial or digital indicator on a magnetic stand; dial test indicator for tight spots | Indicators & Test Indicators · Stands, Holders & Accessories |
| Accept or reject a threaded part | GO and NO GO thread ring or plug gages; 3-wires for pitch diameter | Thread Gages & Thread Measurement |
| Calibrate or zero your own tools | Gage blocks, setting rings, micrometer setting standards, pin gages | Gage Blocks, Pins & Setting Standards |
| Inspect small features without contact | Measuring microscope, profile projector or vision measuring system | Optical & Video Inspection |
Before you order
- Insize ranges are listed in inch and metric; most digital tools switch between the two.
- ISO 17025 calibration certificates are available as separate part numbers on the 1108 digital calipers, 1311 dial calipers and 2307 dial indicators (CAL suffix), and on request for those series. Gage blocks, thread gages, setting rings and other standards list a manufacturer inspection certificate where Insize supplies one.
- Wireless (WL) tools need a receiver; data-output tools need the matching cable. Both are under Data Collection & Wireless.
