The Brown & Sharpe 599-792 Edge Finder is made from Hardness Rockwell C (HRC) 58-rated steel for increased durability, and is fully hardened and precision ground. It can locate round or flat work to within .0005” accuracy, and is rated up to 1,000 RPM. Single-end usability allows use on one end of the instrument. Place in a standard 1/2” diameter collet or chuck to use, and as it rotates and approaches the work edge, the head moves sideways approximately 1/32”. The center of the finder is exactly half the head diameter away from the work.

Edge finders are used to accurately locate the edge of rotating work surfaces up to 1,000 RPM. The rotating instrument has a machine spindle that must come into contact with the spinning work surface for the tool to work.

Brown & Sharpe manufactures precision measuring equipment and metrology hand tools. The company, founded in 1833, played a key role in setting industrial standards in the United States. Brown & Sharpe was acquired by Hexagon Metrology in 2001 and is headquartered in North Kingstown, RI.
