Norton 66260157008 Single Point Diamond Dresser 1/3 Ct

Product Description

The NORTON 66260157008 is a single point diamond dresser designed to true and dress grinding wheels in precision grinding applications. It uses a natural or synthetic diamond tip mounted at a single contact point to remove wheel loading, restore wheel geometry, and expose fresh abrasive grain. The dresser features a 1/3 carat diamond, a 3/8 inch shank diameter, and a 2 inch shank length. It is a non-resettable tool, meaning the diamond is permanently bonded and cannot be repositioned once worn. Grinding machine operators, toolroom technicians, and maintenance machinists install this type of dresser to maintain wheel accuracy and surface finish quality.

Single point diamond dressers are used on surface grinders, cylindrical grinders, and tool and cutter grinders in both production and toolroom environments. This dresser suits applications requiring consistent wheel profile maintenance on aluminum oxide, silicon carbide, and similar conventional abrasive wheels. The 3/8 inch shank fits standard dresser holders and diamond tool blocks found on most bench and pedestal grinding setups as well as precision machine tool fixtures.

Key Features

• Single point contact for precise wheel truing and dressing
• 1/3 carat diamond size suitable for medium-duty dressing operations
• 3/8 inch shank diameter fits standard dresser holders
• 2 inch shank length provides adequate reach in most tool blocks
• Non-resettable design — factory-set diamond orientation

Compatibility

Designed as an OEM-style replacement or direct-use single point diamond dresser for standard 3/8 inch shank dresser holders used on conventional grinding machines.

Installation Notes

Installation is performed by qualified toolroom technicians or machine operators. Power down and lock out the grinding machine before mounting or removing the dresser. Insert the shank fully into the dresser holder and secure according to the machine manufacturer's torque procedure for that holder type. Set the dresser at the manufacturer-recommended angle to the wheel face — do not dress with the shank perpendicular to the wheel, as this accelerates diamond wear. Inspect the diamond tip before each use and replace the dresser when wear flat becomes visible.
