Norton 69014192221 Type 6A2H Diamond Grinding Wheel

Product Description

The NORTON 69014192221 is a Type 6A2H resinoid-bond diamond grinding wheel designed for precision grinding of hard and superhard materials. Built with synthetic diamond abrasive at 320 grit, this wheel delivers extra fine material removal suited for carbide tooling, ceramics, and similar hard substrates. It measures 5 inches in diameter with a 1-inch overall thickness and a 1-1/4-inch hole size. The resinoid bond provides controlled cut action and consistent finish quality. Rated for both wet and dry operation, it fits standard tool and cutter grinding setups used by machinists and tool room technicians.

This wheel is intended for bench or surface grinding applications where fine finish and dimensional accuracy are critical. The Type 6A2H form factor — a straight cup wheel with a diamond face — is commonly used on tool and cutter grinders, surface grinders, and jig grinders when working carbide inserts, PCD tooling, and advanced ceramics. The 1/16-inch superabrasive depth and 1-1/16-inch face width provide a focused grinding contact zone appropriate for precision tool reconditioning work in tool rooms, carbide shops, and grinding operations.

Key Features

• Type 6A2H straight cup wheel geometry with 1-1/16-inch face width for controlled contact
• Synthetic diamond (SD) abrasive at 50 concentration for consistent stock removal
• 320 grit extra fine grade for finish grinding and tight surface finish requirements
• Resinoid bond compatible with wet and dry grinding operation
• 1/16-inch superabrasive depth for extended wheel life in precision applications
• Specification designation SD320-R50B99-1/16 for direct cross-reference and reorder

Compatibility

Designed as an OEM-style replacement or direct application wheel for tool and cutter grinders accepting a 5-inch diameter, Type 6A2H cup wheel with a 1-1/4-inch arbor hole.

Installation Notes

Diamond grinding wheels of this type are installed and dressed by qualified machinists or tool room technicians. Power down and lock out the grinder spindle before mounting or removing the wheel. Verify arbor hole fit and flange seating before operating — never force or overtighten. When running wet, confirm coolant flow is established before engaging the workpiece to avoid thermal shock to the abrasive layer.
