Grier Abrasives W201-N4-17570 Mounted Point Coarse

Product Description

The GRIER ABRASIVES W201-N4-17570 is a cylinder-shaped mounted point abrasive designed for precision grinding, deburring, and surface blending on metal and hard materials. Built from aluminum oxide with a unitized bond and a very hard density rating, this mounted point delivers consistent stock removal and long service life under sustained load. It runs at a maximum of 38,250 RPM and fits a standard 1/8-inch shank, making it compatible with most die grinders and rotary tools used in fabrication and maintenance applications. Licensed trade professionals in metalworking, toolroom, and industrial maintenance environments will find this a reliable consumable for both roughing and finishing passes on ferrous and non-ferrous substrates.

This mounted point is suited for use in die grinders, spindle-driven rotary tools, and bench-mounted grinder setups where a small-diameter cylindrical profile is needed to reach confined areas, ports, or internal bores. Its coarse grade and very hard bond make it a practical choice for initial material removal, weld cleanup, and cavity blending in mold and die work, general fabrication shops, and maintenance and repair operations. The green aluminum oxide construction is optimized for aggressive cutting action on hard steels and similar materials.

Key Features

• Cylinder (W201) point shape for access to slots, bores, and confined grinding surfaces
• Aluminum oxide abrasive material for effective cutting on hard metals
• Coarse grade with very hard density for aggressive stock removal
• Unitized bond construction provides consistent abrasive exposure throughout the wheel life
• Maximum rated speed of 38,250 RPM for use with high-speed die grinders
• 1/8-inch shank diameter and 1.5-inch shank length for secure collet retention

Compatibility

Designed as an OEM-style replacement mounted point for die grinders and rotary tools accepting a 1/8-inch shank collet. Verify that the tool spindle speed does not exceed the 38,250 RPM maximum rating before use.

Installation Notes

Installation and use of mounted abrasive points should be performed by qualified personnel familiar with abrasive safety standards. Ensure the die grinder or rotary tool is fully powered off and unplugged before inserting or removing the shank from the collet. Confirm the tool's maximum free-speed RPM does not exceed the 38,250 RPM rating marked for this point. Always inspect the abrasive for cracks or damage before mounting, and allow the wheel to run at operating speed in a guarded position for a brief run-out check before applying it to the workpiece.
