Ingun GKS-100 319 180 A 1000 Probe, Cupped Tip, 100mil

The INGUN GKS-100 319 180 A 1000 (INGUN item GKS-100-1151) is a standard-stroke test probe on the 2.54 mm (100 mil) grid, plugging into a KS-100 receptacle with quick exchange.

The 19 tip is a 90° inverse cone, slotted and self-cleaning: a funnel-shaped head that captures the end of a round lead and centres it, with slots that turn the cone wall into cutting edges so oxide and flux are scraped away rather than trapped. It is the tip to specify for through-hole leads, header pins and connector posts — especially tinned ones — where a flat or chisel tip would slip off the top of the lead. At ø1.8 mm this is the largest head in the GKS-100 range, sized to swallow the fatter lead diameters. Fitted here with the 1.0 N spring, the lighter of the two common forces for this geometry (the 1500 variant gives 1.5 N).
