Grier Abrasives W183-N4-17569 Mounted Point Coarse

Product Description

The GRIER ABRASIVES W183-N4-17569 is a cylinder-shaped mounted point abrasive designed for precision grinding, deburring, and surface finishing on hard materials. Built with aluminum oxide grain bonded in a unitized, very hard bond, this mounted point delivers consistent stock removal and shape retention through extended use cycles. It fits a 1/8-inch shank and spins safely at up to 51,750 RPM, making it suitable for use in die grinders and rotary tools across production and maintenance grinding applications. The coarse grade removes material aggressively, and the green aluminum oxide composition holds up well against ferrous metals and hard alloys.

This mounted point is used in tool and die work, weld cleanup, mold finishing, and general grinding tasks where a small-diameter abrasive point is needed to access tight geometry or internal surfaces. It is appropriate for both shop-floor production environments and maintenance repair operations. Trades that commonly use this type of abrasive include machinists, fabricators, and maintenance mechanics working with steel, cast iron, and similar hard metals. The cylinder profile suits flat-bottom grinding and side-wall finishing passes.

Key Features

• Cylinder point shape (W183 designation) for flat-bottom and side-wall grinding
• Aluminum oxide abrasive grain for efficient stock removal on ferrous and hard materials
• Coarse grade for aggressive material removal
• Very hard bond density for shape retention and extended wheel life
• 1/8-inch shank diameter compatible with standard die grinders and rotary tools
• Rated to 51,750 RPM maximum operating speed

Compatibility

Designed as an OEM-style replacement or direct-use mounted point for die grinders and rotary tools accepting a 1/8-inch shank collet.

Installation Notes

Mounted points are installed by licensed machinists, fabricators, or maintenance mechanics using a die grinder or compatible rotary tool with a matching 1/8-inch collet. Always confirm the tool's rated RPM meets or exceeds the mounted point's 51,750 RPM maximum before use. Inspect the point for cracks or chips before mounting, and never exceed the marked maximum speed. Secure the shank fully into the collet and tighten per the tool manufacturer's specifications before operating.
