Cratex 40045 Type 27 Grinding Wheel 7in 36 Grit

Product Description

The CRATEX 40045 is a Type 27 depressed center grinding wheel designed for heavy-duty material removal on angle grinders. Built with aluminum oxide abrasive at 36 grit, this wheel falls in the very coarse grade range, making it well suited for aggressive stock removal, weld grinding, and surface prep on steel and similar ferrous metals. At 7 inches in diameter and 1/4 inch thick, with a 7/8 inch arbor hole, it mounts directly to standard angle grinder spindles. The hard wheel hardness rating extends wheel life under sustained contact pressure, and the specification grade A36MTX reflects a bonded abrasive formulation built for consistent cut rate throughout the wheel life.

The 40045 is used in metal fabrication, structural steel work, pipe fitting, and welding cleanup applications. Its Type 27 depressed center profile allows flat and flush grinding without the wheel hub obstructing contact with the workpiece surface. Typical users include pipefitters, ironworkers, welders, and general maintenance tradespeople who need reliable stock removal on a 7 inch angle grinder. It performs on grinding welds flush, removing mill scale, and prepping surfaces before welding or coating.

Key Features

• Type 27 depressed center profile allows flush surface contact during grinding
• 36 grit aluminum oxide abrasive for very coarse, aggressive material removal
• 7 inches diameter by 1/4 inch thickness for use on standard 7 inch angle grinders
• 7/8 inch arbor hole with arbor connector type for direct spindle mounting
• Hard wheel hardness rating extends service life under heavy load
• A36MTX specification grade bonded abrasive construction

Compatibility

Designed for use with angle grinders accepting a 7 inch Type 27 depressed center wheel with a 7/8 inch arbor mount. Verify that the grinder spindle speed rating meets or exceeds the maximum RPM marked on the wheel before installation.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with abrasive wheel safety. Always power down and unplug or lock out the angle grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never mount a damaged wheel. Ensure the grinder guard is properly positioned and that the grinder spindle speed does not exceed the wheel rated speed.
