Norton 69014192064 Diamond Grinding Wheel 4in 220 Grit

Product Description

The NORTON 69014192064 is a Type 1A1R diamond surface grinding wheel designed for precision surface grinding applications. Built with Armored Synthetic Diamond (ASD) abrasive and a metal bond, this wheel delivers consistent stock removal and fine surface finishes on hard, brittle materials. At 4 inches in diameter with a 0.012-inch thickness and a 1/2-inch arbor hole, it is suited for use on surface grinders requiring a thin, straight-profile wheel. The fine grade and 220 grit rating produce smooth finishes where tight tolerances are required. Weighing 0.53 pounds, it is a compact, single-piece unit suitable for high-precision toolroom and production grinding work.

This wheel is used in surface grinding operations on hard materials such as carbide, ceramics, glass, and hardened tool steels. The Type 1A1R profile makes it appropriate for flat-face grinding passes on horizontal-spindle surface grinders. It is typically installed and operated by machinists, tool and die makers, and grinding specialists in toolroom, job shop, and manufacturing environments. The 1/8-inch superabrasive depth and 75 concentration rating support controlled, repeatable material removal over the wheel's service life.

Key Features

• 220 grit fine-grade diamond abrasive for smooth surface finish results
• Armored Synthetic Diamond (ASD) superabrasive type for durability on hard materials
• Metal bond construction maintains wheel form and supports consistent cut rates
• Type 1A1R straight wheel profile for flat-face surface grinding
• 1/8-inch superabrasive depth with 75 concentration for extended usable life
• Hardness Code N, medium hardness rating for balanced performance on a range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-fit grinding wheel for horizontal-spindle surface grinders accepting a 4-inch diameter, 1/2-inch arbor hole, Type 1A1R wheel. Verify spindle speed rating and arbor compatibility before mounting.

Installation Notes

Diamond grinding wheels must be mounted and dressed only by qualified machinists or grinding equipment operators following machine manufacturer guidelines and ANSI B11.23 safe-use standards. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation and never exceed the rated maximum operating speed marked on the wheel or its blotter. Ring-test procedures do not apply to metal-bond superabrasive wheels — follow the manufacturer-specified inspection method instead.
