17 1/2" Tricone Bit Gauge | Go & No-Go Drill Bit Inspection Tool

The Safety Shark 17 1/2" Tricone Bit Gauge is a precision inspection tool designed to verify the outside diameter of 17 1/2" tricone drill bits before they are run downhole. Manufactured from high-strength alloy steel, this gauge provides a quick and accurate method of confirming that new, refurbished and used drill bits remain within the required dimensional tolerances. By ensuring the bit is correctly sized, operators can reduce the risk of downhole complications, improve drilling efficiency and maintain compatibility with casing, stabilisers and other bottom hole assembly components.

Available as either a Go Gauge or No-Go Gauge, the 17 1/2" Bit Gauge provides a simple pass/fail inspection process. A Go Gauge confirms that the drill bit does not exceed its maximum allowable diameter, while a No-Go Gauge verifies that the bit has not worn below the minimum acceptable size. Regular inspection using calibrated bit gauges helps maximise bit performance, maintain hole quality and reduce unnecessary trips caused by out-of-gauge drilling tools.

Manufactured for demanding oilfield, geothermal, mining and water well drilling applications, Safety Shark Bit Gauges are precision-machined for long service life and repeatable inspection accuracy. They are suitable for drilling contractors, inspection companies, repair workshops and equipment rental fleets requiring reliable dimensional verification of tricone drill bits.
