Value Collection PLMSC13022 Flap Disc 40 Grit Type 29

Product Description

The VALUE COLLECTION PLMSC13022 is a Type 29 flap disc designed for aggressive material removal on steel and stainless steel surfaces. At 4.5 inches in diameter with a 7/8 inch arbor hole, it mounts directly to standard angle grinders using an arbor hole attachment. The abrasive material is zirconia alumina at 40 grit, placing it in the coarse grade range — well suited for weld blending, deburring, and surface conditioning where fast stock removal is the priority. The poly-cotton backing provides flexibility, allowing the disc to conform slightly to contoured or irregular workpiece surfaces during use.

This flap disc is used in fabrication shops, field metalwork, and maintenance applications involving ferrous and non-ferrous steel. The Type 29 conical geometry positions the abrasive at an angle to the workpiece, which increases contact surface area compared to a flat Type 27 disc. This makes it a common choice when working on flat stock, sheet metal, and structural steel where blending and finishing passes follow initial cutting or welding operations. It is installed and operated by fabricators, ironworkers, pipefitters, and maintenance technicians using a standard 4.5 inch angle grinder.

Key Features

• Zirconia alumina abrasive delivers consistent cut rate on steel and stainless steel
• Type 29 conical shape increases abrasive contact for faster material removal on flat surfaces
• 40 grit coarse grade for weld blending, deburring, and aggressive stock removal
• 7/8 inch arbor hole fits standard 4.5 inch angle grinder spindles
• Poly-cotton backing allows moderate flex for work on irregular surfaces
• Blue disc color aids identification on the job site

Compatibility

Designed for use with 4.5 inch angle grinders equipped with a 7/8 inch arbor spindle. Suitable for material applications on steels and stainless steel.

Installation Notes

A licensed or experienced operator should inspect the disc for damage before mounting and confirm the grinder RPM rating meets or exceeds the disc maximum rated speed. Power down and disconnect the grinder before mounting or removing the disc. Always install the proper guard and use appropriate PPE including face shield and gloves when operating flap discs on metal. Do not use this disc on materials outside its rated material applications.
