Value Collection PLMSC13121 Flap Disc 36 Grit Type 29

Product Description

The VALUE COLLECTION PLMSC13121 is a Type 29 coated flap disc designed for aggressive material removal on steel and stainless steel surfaces. It measures 4.5 inches in diameter with a 5/8-11 threaded arbor hole for direct mounting on standard angle grinders. The disc uses zirconia alumina abrasive at 36 grit, placing it in the extra coarse grade range. This combination delivers fast stock removal and moderate heat resistance, making it a practical choice for weld blending, surface prep, and deburring work. The poly-cotton backing provides flexibility and durability through extended use. Licensed trades and fabrication shops rely on this disc type for heavy grinding tasks.

This flap disc is suited for grinding and surface conditioning on mild steel, carbon steel, and stainless steel. The Type 29 conical design angles the flaps for more aggressive contact with flat and contoured workpieces compared to a flat Type 27 disc. It is commonly used in metal fabrication shops, structural steel work, and pipeline maintenance where fast material removal at a consistent finish is required. The 5/8-11 thread mount fits the majority of 4.5-inch angle grinders used in the field.

Installation Notes

Installation and disc changes must be performed with the grinder powered off and unplugged or battery removed. Confirm the grinder spindle thread is 5/8-11 before mounting. Always verify the grinder RPM rating meets or exceeds the disc RPM rating before use. Wear appropriate eye, face, and hand protection per ANSI and applicable shop safety standards when operating angle grinders with abrasive discs.
