Mitutoyo 950-206 Drill Gage 1/16 to 1/2 Inch 29 Holes

Product Description

The MITUTOYO 950-206 is an inch-system drill gage used to verify hole sizes ranging from 1/16 inch to 1/2 inch. It contains 29 precision-machined holes that allow technicians and tradespeople to quickly identify drill bit sizes and confirm drilled hole diameters on the job. The gage body measures 6-3/8 inches long and 2-1/2 inches wide, making it compact enough for a tool pouch or bench drawer. This type of tool is standard in any shop where accurate hole sizing matters, including HVAC, plumbing, electrical, and general fabrication environments.

The 950-206 is suited for use in both shop and field settings where inch-standard drill bits are in use. It covers the most common fractional drill sizes encountered in trade work, from small pilot holes at 1/16 inch up through 1/2 inch diameter. Machinists, electricians, pipefitters, and sheet metal workers will find this gage useful for confirming bit size before use or verifying a drilled hole before tapping or fitting a fastener.

Installation Notes
