Norton 61463624528 Mounted Point W186 60 Grit 1/4 in Shank

Product Description

The NORTON 61463624528 is a cylinder-shaped mounted point abrasive designed for precision grinding, deburring, and surface finishing on metal and other hard materials. Built with aluminum oxide abrasive bonded in a vitrified matrix, this W186-profile point delivers consistent stock removal at a medium, 60-grit cut. The 1/4-inch shank diameter fits standard die grinders and rotary tools used throughout fabrication, maintenance, and toolroom environments. Rated to 40,500 RPM, it handles demanding grinding applications while maintaining control in tight bores and contoured workpieces. Licensed tradespeople and industrial maintenance technicians are the primary installers and users of this type of abrasive point.

This mounted point suits applications where a right-angle or straight die grinder reaches cavities, ports, weld seams, or internal radii that bench grinders and angle grinders cannot access. The W186 cylinder shape is well suited for flat-bottom internal grinding, port matching, and surface blending in ferrous and non-ferrous workpieces. The vitrified bond resists loading and maintains a consistent cut rate across the life of the point. It is sold individually and is a direct fit for 1/4-inch collet die grinders common in HVAC fabrication shops, plumbing rough-in work, and general mechanical service environments.

Key Features

• W186 cylinder point shape for flat-bottom and internal grinding applications
• Aluminum oxide abrasive with vitrified bond for consistent, cool cutting action
• 60 grit, medium grade — balanced between aggressive stock removal and surface quality
• Rated to 40,500 RPM for use with standard die grinders
• 1/4-inch shank diameter fits most collet-style die grinders and rotary tools
• 3/4-inch head thickness provides adequate contact area for controlled grinding passes

Compatibility

Designed for use with die grinders and rotary tools equipped with a 1/4-inch collet. Typical fitment includes straight and right-angle die grinders used in metalworking, fabrication, and mechanical service applications.

Installation Notes

Always inspect the mounted point for cracks or chips before mounting. Secure the shank fully into the collet per the tool manufacturer's minimum insertion depth requirement before operating. Wear appropriate eye protection and a face shield, and ensure the tool's rated RPM meets or exceeds the point's 40,500 RPM maximum before use. Never exceed the maximum RPM marked on the abrasive or operate with a damaged or unbalanced point.
