Weiler 50606 Flap Disc 120 Grit 4.5 in Type 29 Zirconia

Product Description

The WEILER 50606 is a Type 29 zirconia alumina flap disc designed for aggressive material removal and surface finishing on ferrous metals. Part of the Original Tiger series, it features a fine 120-grit abrasive on cloth backing with an aluminum backing plate for rigidity and heat dissipation. The phenolic-free aluminum plate keeps the disc stable at speeds up to 13,000 RPM. At 4.5 inches in diameter with a 7/8-inch arbor hole, this disc mounts directly to standard angle grinders. Metal fabricators, welders, and ironworkers reach for this disc when blending welds or cleaning surfaces before coating or inspection.

The WEILER 50606 is suited for use on steel, stainless steel, and cast iron. Its Type 29 conical shape presents the abrasive at an angle, making it effective for both flat stock and contoured surfaces. Typical applications include weld removal, slag cleanup, and surface preparation prior to painting or welding. The fine 120-grit rating produces a smoother finish than lower-grit options, making it a good final-pass disc in a multi-step grinding process.

Key Features

• Type 29 conical profile for aggressive contact on flat and contoured surfaces
• 120-grit zirconia alumina abrasive for fine material removal and surface blending
• Cloth backing for flexibility and conformability during grinding
• Aluminum backing plate provides rigidity and supports high-speed operation
• Rated to 13,000 RPM for use with standard 4.5-inch angle grinders
• Suitable for steel, stainless steel, and cast iron applications

Compatibility

Designed as a direct-mount replacement for standard 4.5-inch angle grinders with a 7/8-inch arbor hole. Suitable for use on steel, stainless steel, and cast iron workpieces.

Installation Notes

Installation should be performed by a qualified metalworker or fabricator following the grinder manufacturer's mounting instructions. Always inspect the disc for damage before mounting and confirm the grinder's rated speed meets or exceeds 13,000 RPM before use. Wear appropriate PPE including eye protection and gloves when operating angle grinders. Ensure the workpiece is secured and the grinder guard is properly positioned before starting the tool.
