Norton 66260195212 Diamond Dresser Concave Radius

Product Description

The NORTON 66260195212 is a single-point diamond dresser designed to true and dress grinding wheels to precise concave radius profiles. The tool features a 3/8 inch shank diameter and a 2 inch shank length, fitting standard dressing tool holders commonly found on surface grinders, cylindrical grinders, and bench grinding setups. The concave point shape produces a defined radius form on the wheel face, making it the right choice when a radiused grinding path is required. This type of dresser is used by machinists, tool grinders, and grinding wheel operators in production and maintenance environments.

This dresser is suited for applications where a controlled concave radius must be maintained on the grinding wheel. The minimum radius is 0.0210 inches and the maximum radius is 0.0320 inches, placing it in the range used for fine-form grinding work. It is intended for single-use service in a fixed mount position and is not resettable once the diamond point is worn. Typical installations include horizontal-spindle surface grinders, OD and ID cylindrical grinders, and toolroom grinders where form accuracy is critical.

Key Features

• 3/8 inch shank diameter fits standard grinding machine dressing tool holders
• 2 inch shank length provides clearance for typical wheel guard and holder configurations
• Radius range of 0.0210 to 0.0320 inches suited for fine-form and finishing grind applications
• Non-resettable design — replace when diamond point is worn

Compatibility

Designed as an OEM-style single-point diamond dresser for use in standard 3/8 inch dressing tool holders on surface, cylindrical, and toolroom grinding machines requiring concave radius wheel dressing.

Installation Notes

Diamond dressers of this type are installed and serviced by machinists or grinding machine operators. Before mounting or replacing the dresser, power down and lock out the grinding machine per applicable safety procedures. Secure the shank firmly in the dressing tool holder to prevent movement during dressing passes. Use light, consistent traverse passes across the wheel face and avoid excessive depth of cut per pass, which can fracture the diamond point prematurely.
