Pro Level Surface Roughness Tester Probes Including Standard Curved Small Hole And Deep Groove Sensors Plus Extension Rod Adapter Designed For KR220 Gage To Deliver Slick Reading And Hustle Ready Performance

Professional Surface Roughness Probe Kit For KR220 Gauges
✔️ Standard curved hole groove sensors plus 50mm extension rod adapter

This complete probe set upgrades your KR220 digital tracker with multiple measuring heads designed for daily shop work. Each attachment swaps quickly onto the main unit to test flat surfaces, tight bores, and narrow grooves during routine quality control checks and machining inspections.

✅ Flat surface and inner hole measurement capabilities above 5mm
✅ Narrow bore detection handling diameters larger than 6mm up to 22mm depth
✅ Radius testing optimized for surface curves exceeding 3mm
✅ Deep channel scanning for slots wider than 2mm and under 3mm deep
✅ Fifty-millimeter reach extension bar for deeper component access
✅ Flexible steering adapter lever for precise angle positioning
✅ Complete kit features blue anodized aluminum construction

💡 What gear choices actually improve surface finish readings on tricky parts?
This specific assembly drops straight into your digital tracker to keep measurement noise down and deliver repeatable data across different shop jobs.
- Matching the pointer shape to the cut geometry cuts down wobble during slow sweep passes.
- Adding the handy extension bar reaches deep cavities without bending the sensitive tracking needle.
- Clearing grit off the rails stops false spikes and keeps run-to-run data predictable.
- Quick swap heads let techies move between flat slabs and tight bores without pausing the workflow.
