Norton 66260195190 Diamond Thread Dresser 3/8 in Shank

Product Description

The NORTON 66260195190 is a single-point diamond thread dresser designed for precision dressing of grinding wheels with thread profiles. Built with a 60-degree included angle and a maximum radius of 0.010 decimal inches, this tool produces accurate thread forms on abrasive wheels used in thread grinding operations. The 3/8-inch shank diameter fits standard dresser holders, and the 1-5/8-inch shank length provides adequate reach for most bench and cylindrical grinding setups. Installation and use are handled by machinists and grinding machine operators in tool rooms, production grinding cells, and precision machining environments.

This diamond thread dresser is suited for thread grinding applications in both production and toolroom settings. It is used to restore or true grinding wheels that cut thread profiles on workpieces such as screws, bolts, worms, and threaded gauges. The single-point configuration gives the operator control over dressing depth and pass rate, making it appropriate for precision grinding work where wheel geometry directly affects thread accuracy. It is not resettable, so replacement is required once the diamond is worn.

Installation Notes

Diamond dressers are installed and operated by machinists or grinding machine operators. Power down and lock out the grinding machine before mounting or removing the dresser from the holder. Secure the shank firmly in the holder to prevent movement during dressing passes. Follow the machine manufacturer's recommended dressing feed rates and traverse speeds to avoid premature diamond wear or wheel damage.
