Cgw 42315 Zirconia Flap Disc 4.5 in T27 80 Grit 10 Pack

Product Description

The CGW 42315 is a Type 27 zirconia alumina flap disc designed for aggressive material removal and blending on metal surfaces. Measuring 4.5 inches in diameter with a 5/8-11 threaded hub, this disc mounts directly to standard angle grinders. The 80-grit zirconia abrasive delivers a consistent cut rate and extended disc life compared to standard aluminum oxide, making it a reliable choice for fabricators, welders, and metalworkers who need sustained stock removal without frequent disc changes. Sold in a box of 10 discs.

This flap disc is suited for grinding, blending, and finishing on mild steel, stainless steel, and other ferrous metals in fabrication shops, welding operations, and structural steel work. The T27 flat profile allows flush-to-surface grinding, which is preferred when working on flat stock, weld seams, and edge preparation. The 5/8-11 arbor fits the most common angle grinder spindle size used in trade and industrial environments.

Key Features

• Zirconia alumina abrasive for longer service life and higher cut rate than standard aluminum oxide
• Type 27 flat profile for flush surface contact and weld blending
• 4.5-inch diameter with 5/8-11 threaded hub fits standard angle grinders
• 80 grit for medium-aggressive stock removal and pre-finish blending

Compatibility

Designed for use with angle grinders equipped with a 5/8-11 spindle thread, which is the standard configuration for 4.5-inch class grinders across most major tool brands.

Installation Notes

Mounting and disc changes must be performed with the grinder unplugged or the battery removed. Verify the grinder's rated RPM meets or exceeds the maximum RPM rating marked on the disc before use. Wear appropriate PPE including a face shield and gloves when operating angle grinders. Inspect the disc for damage before each use and discard any disc that shows delamination, cracking, or unusual wear.
