Norton 69014191852 Surface Grinding Wheel 7in 220 Grit

Product Description

The NORTON 69014191852 is a Type 1A1 superabrasive surface grinding wheel engineered for precision finishing operations on hard and difficult-to-grind materials. Built with a synthetic diamond (SD) abrasive and a resinoid bond, this wheel delivers consistent stock removal and a fine surface finish in wet grinding applications. At 7 inches in diameter, 3/8 inches thick, and with a 1-1/4 inch arbor hole, it mounts on standard surface grinding equipment. The 220 grit, very fine grade makes it well suited for final-pass finishing rather than aggressive material removal. Wheel hardness is rated Soft (R), and the superabrasive depth is 1/4 inch at 100 percent concentration.

This wheel is intended for finishing operations on carbide, ceramics, glass, hardened tool steels, and other hard substrates where conventional abrasives lose efficiency. The Type 1A1 straight-wheel profile fits standard surface grinder spindles. Wet operation is required to maintain wheel integrity, manage heat, and flush swarf. Toolroom machinists, grinding specialists, and precision fabrication shops are the primary installers and operators of this wheel.

Key Features

• Synthetic diamond (SD) abrasive for grinding hard and brittle materials
• Resinoid bond provides controlled wear and smooth cutting action
• 220 grit very fine grade optimized for finishing passes
• Type 1A1 straight wheel profile with no recess for broad spindle compatibility
• Wet operation design for heat management and extended wheel life
• 100 percent superabrasive concentration (SD220-R100B99-1/4) for consistent performance

Compatibility

Designed as an OEM-style replacement and standard-fitment superabrasive grinding wheel for surface grinders accepting a 7 inch diameter, 1-1/4 inch arbor hole, Type 1A1 straight wheel configuration.

Installation Notes

Installation and dressing of superabrasive wheels should be performed by a qualified grinding machine operator or toolroom technician familiar with ANSI B7.1 wheel safety standards. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and verify that the machine's maximum RPM rating meets or exceeds the wheel's rated speed. Wet coolant flow must be active before the wheel contacts the workpiece to prevent thermal damage to the bond and abrasive layer.
