Reach Deep Recesses: Why You Need a Needle Contact Point

Standard spherical indicator tips work great for flat surfaces, but they fail when inspecting tight spaces. Thick, rounded tips simply cannot penetrate small holes, deep grooves, or narrow slots. A needle contact point solves this exact reach issue. Featuring a slender, pointed shaft, this essential accessory allows technicians to measure hard-to-access part features with complete accuracy.

What Is a Needle Contact Point?

A needle contact point is a specialized tip that threads onto dial indicators, test indicators, and electronic depth gages. It features a fine, narrow probe tip—often made of hardened steel or durable carbide. This elongated design reaches deep into tiny crevices, transmitting small surface variations directly to your measuring instrument.

Top Advantages for Precision Inspection

• Access Ultra-Narrow Features: The slim profile easily slides into small keyways, narrow splines, deep grooves, and recessed internal steps.

• Pinpoint Measurement Accuracy: A sharp point contacts extremely small target areas, giving you precise positional data on complex machined geometries.

• Exceptional Wear Resistance: Crafted from hardened steel or solid carbide, these probe tips resist bending, chipping, and surface wear over thousands of cycles.

• Universal Thread Compatibility: Standardized M2.5 or 4-48 UNF mounting threads let you swap needle points quickly onto your existing indicator tools.

Primary Industry Applications

1. Groove and Slot Inspection: Measure the depth and bottom surface flatness of narrow internal snap-ring grooves.

2. PCB and Electronic Testing: Reach around crowded circuit board components to test precise contact heights.

3. Small Hole Inspections: Inspect internal shoulder distances and small chamfers inside drilled workpieces.

4. Toolroom Setup: Align delicate dies, molds, and fixture stops in cramped machining environments.
