Cgw 48105 Zirconia Resin Fibre Disc 60 Grit 25 Pack

Product Description

The CGW 48105 is a zirconia alumina resin fibre disc designed for aggressive material removal on metal, stainless steel, and other hard surfaces. Measuring 4-1/2 inches in diameter with a 7/8-inch arbor hole, this disc mounts directly to standard angle grinders and disc sanders. At 60 grit, the Type ZIRK abrasive delivers a fast cut rate with reasonable disc life, making it a reliable choice for weld blending, surface conditioning, and stock removal tasks. Each box contains 25 discs, keeping crews stocked for extended production runs without frequent reordering.

These fibre discs are suited for metal fabrication shops, structural steel work, and general grinding applications where a mid-range grit is needed for both material removal and surface prep. They are commonly used by welders, pipefitters, ironworkers, and sheet metal mechanics working on carbon steel, stainless, and other ferrous materials. The 4-1/2-inch diameter is the most common angle grinder size in the trade, making this disc a direct fit for the majority of handheld grinders on the job site or in the shop.

Key Features

• Zirconia alumina abrasive (Type ZIRK) for high cut rate and extended disc life compared to aluminum oxide
• 4-1/2 inches diameter with 7/8-inch arbor hole for standard angle grinder compatibility
• 60 grit for aggressive stock removal and weld blending
• Resin fibre backing provides flexibility and durability under load
• 25 discs per box for production-level supply

Compatibility

Designed for use with standard 4-1/2-inch angle grinders and disc sanders fitted with a 7/8-inch arbor or a compatible disc pad backing plate.

Installation Notes

Fibre discs require a matched backing pad rated for the disc diameter and arbor size before mounting to a grinder. Always confirm the grinder RPM rating meets or exceeds the disc RPM rating before operation. Wear appropriate PPE including face shield, gloves, and hearing protection during use. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of delamination or wear through to the backing.
