Value Collection BD3046 Type 27 Grinding Wheel 4.5in

Product Description

The VALUE COLLECTION BD3046 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal and fabricated workpieces. Built with aluminum oxide abrasive and a resinoid bond, this wheel delivers consistent cut rate and thermal resistance through extended grinding passes. At 4.5 inches in diameter and 0.25 inches thick, it fits standard 4.5-inch angle grinders with a 7/8-inch arbor hole. The 13,300 maximum RPM rating keeps it within the operating envelope of most common right-angle grinders used in fabrication, welding prep, and structural steel work. Installers and fabricators should verify grinder nameplate RPM does not exceed the wheel rating before mounting.

This wheel is suited for use in metal fabrication shops, welding operations, construction sites, and maintenance environments where surface grinding, weld blending, and edge cleanup are routine tasks. The Type 27 depressed-center profile positions the abrasive face at an angle to the workpiece, making it effective for flat and contoured surface grinding where a flat wheel profile would be limiting. It is installed by trade professionals including ironworkers, pipefitters, welders, and general maintenance mechanics.

Key Features

• Aluminum oxide abrasive for reliable performance on ferrous metals and general-purpose grinding
• Resinoid bond provides vibration dampening and consistent wheel integrity under load
• Type 27 depressed-center profile allows low-angle flat surface and weld grinding
• 13,300 max RPM rating compatible with standard 4.5-inch angle grinders
• 7/8-inch arbor hole fits the most common angle grinder spindle size
• 0.25-inch thickness provides a balance of material removal rate and wheel rigidity

Compatibility

Designed as a replacement or consumable grinding wheel for standard 4.5-inch angle grinders equipped with a 7/8-inch arbor, operating at or below 13,300 RPM.

Installation Notes

Angle grinder wheels must be installed and changed by personnel familiar with abrasive wheel safety. Always power down and disconnect the grinder from its power source before changing wheels. Confirm the grinder spindle speed does not exceed the 13,300 RPM maximum marked on the wheel — never use a wheel on a machine whose rated speed exceeds the wheel rating. Inspect the wheel for cracks or damage before each use and follow ANSI B7.1 safe-use guidelines for abrasive wheels.
