Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, this 5-inch, 40-grit disc delivers a fast, consistent cut rate throughout its service life. As the abrasive flaps wear down, fresh mineral is continuously exposed, maintaining cutting performance from first use to last. It is well-suited for medium to high-pressure grinding tasks and is typically installed and used by metalworkers, fabricators, and maintenance trades working with angle grinders.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is used in applications that require both aggressive stock removal and an acceptable surface finish in the same pass. Common tasks include beveling, weld removal, and edge deburring on a range of ferrous and non-ferrous metals. The right-angle Type 29 configuration provides a low disc-to-workpiece angle, making it effective on flat and contoured surfaces. Its design reduces the risk of gouging compared to fiber discs and bonded grinding wheels, which is an advantage in finish-sensitive applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3M Precision-Shaped Grain delivers a fast cut rate for increased productivity during aggressive grinding\u003c\/li\u003e\n  \u003cli\u003e5-inch diameter, 40-grit abrasive suited for medium to high material removal on metal\u003c\/li\u003e\n  \u003cli\u003eDurable polyester backing withstands high unit pressure without delaminating\u003c\/li\u003e\n  \u003cli\u003eSelf-renewing flap design exposes fresh mineral as disc wears, maintaining consistent cut rate\u003c\/li\u003e\n  \u003cli\u003eLower gouging risk compared to fiber discs and bonded wheels, supporting finish-critical work\u003c\/li\u003e\n  \u003cli\u003eEffective for beveling, weld removal, and edge deburring in fabrication and maintenance settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on standard 5-inch right-angle grinders.
