Merit Abrasives 63642505647 Quick-change Disc 2in 40G

Product Description

The MERIT ABRASIVES 63642505647 is a TR-style quick-change abrasive disc designed for rapid disc swaps on angle grinders and die grinders equipped with a Type R attachment system. The disc measures 2 inches in diameter and is coated with aluminum oxide abrasive at 40 grit, placing it in the coarse grade range. The abrasive is bonded to a cloth backing rated at X-weight, delivering durability under aggressive stock removal conditions. Rated to 30000 RPM, this disc suits high-speed grinder use in metal fabrication, weld prep, and surface conditioning tasks. It is sold individually with a minimum order quantity of 25 units.

This disc is well suited for metalworking applications where fast material removal is the priority. The TR quick-change mount allows tool-free disc changes, reducing downtime on production or field work. Typical applications include deburring, weld blending, rust removal, and edge chamfering on steel and other ferrous metals. The coarse 40-grit cut is appropriate for initial grinding passes rather than finish work. Fabricators, pipefitters, ironworkers, and general metalworking tradespeople are the primary users of this product.

Installation Notes

Installation should be performed by a qualified metalworking tradesperson or operator familiar with abrasive disc safety. Power down and disconnect the grinder from its power source before mounting or removing the disc. Verify that the grinder's rated RPM meets or exceeds 30000 RPM and that the tool spindle uses a TR-compatible Type R adapter before mounting. Always inspect the disc for damage before use and wear appropriate PPE including face shield, gloves, and hearing protection during grinding operations.
