Norton 69014192024 Surface Grinding Wheel 150 Grit 4 in

Product Description

The NORTON 69014192024 is a Type 1A1 diamond surface grinding wheel built for wet grinding applications in roughing and finishing operations. The wheel uses a synthetic diamond (SD) abrasive bonded with a resinoid bond system, rated at 100 concentration for consistent stock removal and surface quality. At 150 grit and a Very Fine grade, it is suited for finish grinding hard materials where tight tolerances and smooth surface finish are required. The wheel measures 4 inches in diameter, 0.125 inches thick, with a 0.75 inch hole, and weighs 0.29 pounds. The superabrasive depth is 0.25 inches. Licensed HVAC, tool-room, and precision grinding technicians install and dress this wheel class.

This wheel is intended for surface grinding applications on hard or brittle materials such as carbide, ceramic, glass, and hardened steel. Its Type 1A1 flat wheel profile makes it appropriate for surface grinders with horizontal spindles. The Soft hardness rating (Hardness Code R) allows the wheel to release dull abrasive grains efficiently, maintaining cut rate during wet operations. The SD150-R100B99-1/4 specification designates the full abrasive system for reference when matching or sourcing replacement wheels. This wheel is part of the Norton Diamond series and is suited for both roughing and finishing passes in a single setup.

Key Features

• Synthetic diamond abrasive at 150 grit for Very Fine material removal on hard surfaces
• Resinoid bond with 100 concentration for consistent abrasive delivery and cool cutting
• Type 1A1 flat wheel profile for use on horizontal-spindle surface grinders
• Rated for wet operation, reducing heat buildup and extending wheel life
• Soft hardness rating (R) promotes self-dressing action and maintains sharpness
• No recess, no taper — straightforward mounting on standard 0.75 inch arbors

Compatibility

Designed as an OEM-style replacement or direct-fit surface grinding wheel for horizontal-spindle surface grinders accepting a Type 1A1 wheel with a 4 inch diameter and 0.75 inch hole.

Installation Notes

Surface grinding wheels of this type are mounted and dressed by qualified tool-room or grinding machine operators. 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 operating speed marked on the wheel or machine. Wet grinding requires confirmed coolant flow before engaging the wheel with the workpiece.
