Can I use Insize depth gauges near CNC coolant?

Yes. The Insize 1149 series is IP67 waterproof, built for coolant-heavy environments including CNC machining centres and grinding machines. Standard models (1141 series) should be kept away from direct coolant. Both are available at Shri Narayan Machinery LLP, Noida.

Which Insize depth gauge is most popular in Indian machine shops?

The Insize 1141-150A (0-150mm digital depth gauge) is the most widely used model across Indian manufacturing. For budget-conscious shops, the 1240-2001 vernier depth gauge (0-150mm, 0.02mm graduation) offers excellent value without needing batteries. Both are stocked at our Noida location.

Insize Digital Depth Gauges & Depth Micrometers

Name: Insize Digital Depth Gauges & Depth Micrometers
Brand: Insize

Keyway depths, counterbores, blind holes: Insize depth gauges cover them all. The digital 1141 series reads to 0.01mm across 0-150mm to 0-500mm ranges, stretching to 1000mm with extension rods, while the 1149 series carries an IP67 rating for grinding coolant and wash-down zones. Need tighter tolerance? Depth micrometers step from 0.01mm (3240 series) down to 0.001mm resolution (3540 series), with ±0.004mm accuracy on the 0-25mm range. Hook types (1142, 1245 series) measure off internal shoulders, the 1240 vernier series works battery-free at 0.02mm graduation, and 260mm or 320mm extension bases (6141 series) steady the gauge on large workpieces. Die makers, engine shops, and CNC job shops in Noida-NCR use these every day. Stocked at Sector 9, Noida; WhatsApp for price.

Frequently Asked Questions: Depth Gauges

A depth gauge (1141 series) uses a sliding scale similar to a caliper. It has wider range (up to 1000mm with rods) and is faster for routine measurements. A depth micrometer (3240 and 3540 series) uses a thimble mechanism. It offers higher accuracy (±0.004mm vs ±0.02mm) and is preferred for precision depth work in quality labs. Choose based on your accuracy requirement and range.
