Bridge the Gap in Your Depth Inspections

Standard depth gauges work beautifully on small holes and narrow slots. However, you will inevitably encounter wide bores or large cavities that swallow your tool's standard base. A high-quality set of extension bases for depth gage setups solves this common workshop bottleneck. They expand your measurement footprint without compromising your accuracy.

What are Depth Gage Extension Bases?

Extension bases are precision-ground metal attachments designed to extend the span of your existing depth micrometer or caliper. They bolt directly onto the bottom of your tool's original base.

By widening the contact surface, they allow your gauge to sit securely across massive openings. This accessory transforms a standard inspection tool into a highly versatile heavy-duty gauge.

Key Advantages for Large-Scale Machining

Adding these precision extensions to your tool chest provides immediate benefits:

• Bridges Large Spans: They allow you to measure deep recesses on wide engine blocks or large flanges easily.

• Precision-Ground Alignment: Manufacturers lapped the mounting surfaces perfectly flat to maintain absolute parallelism.

• Cost-Effective Versatility: They eliminate the need to purchase multiple expensive, oversized depth gauges.

• Rock-Solid Stability: The added weight and width prevent rocking errors during critical quality checks.

Pro Tips for Flawless Installation

Installation Tip: Clean both the tool base and the extension mounting surface meticulously before fastening them together. A single trapped microscopic burr will tilt your gauge and ruin your calibration.

After mounting the extension base, always re-zero your depth gauge on a certified master surface plate. This practice ensures your interchangeable rods still read perfectly true across the wider span.

Stop letting wide workpiece cavities stall your production line. Invest in premium extension bases for depth gage kits today to maximize your shop's measurement capabilities.
