Professional Indirect Measurement for Deep Bore Applications
Precision machining requires more than just a quick measurement; it requires a “feel” for the part. The Dasqua 5911-0002 Telescoping Gauge Set provides machinists and quality inspectors with a reliable method for checking internal dimensions in deep recesses. Unlike standard sets, the 6-inch handle length provides the necessary leverage and reach for engine blocks, hydraulic cylinders, and deep-pocket mold work.
Industrial Build Quality & Precision
Each gauge in this 6-piece set is manufactured with hardened and satin-chrome finished plungers. The contact points are precision ground to a radius that ensures accurate seating even in slightly out-of-round holes. The knurled locking knob at the end of the handle allows for a smooth, secure lock once the “sweet spot” of the bore is found, preventing any measurement drift during tool extraction.
Shop-Floor Benefits
- Extended Reach: 6-inch handles allow for measurement in deep bores where standard 3″ or 4″ gauges fail.
- Uniform Tension: Constant spring pressure provides a consistent tactile response for better repeatability between operators.
- Satin Chrome Finish: Reduces glare and provides superior rust resistance in humid shop environments.
- Self-Centering: Double-action plungers automatically center themselves within the bore for faster setup.
Recommended Use & Best Practices
- Measurement Transfer: Always use a calibrated outside micrometer to read the dimension from the gauge plungers.
- The “Rocking” Technique: Lightly rock the gauge through the center of the bore to find the true minimum diameter before locking.
- Maintenance: Keep plungers lightly oiled with precision instrument oil to ensure smooth telescoping action.
