Abrasive Flap Disc Proline 125 mm Grit 60, Model 44855

Proline abrasive flap disc 125 mm, grit 60, model 44855 is a bonded flap wheel designed for use with standard angle grinders. The disc combines overlapping abrasive flaps on a reinforced backing to deliver material removal and surface conditioning on ferrous metals and stainless steel. It is intended for operations such as deburring, weld seam blending, removal of rust and mill scale, and preparing metal surfaces for further finishing or painting.

Advantages

The flap disc design provides consistent cut rate with controlled stock removal while maintaining a more even finish compared to traditional grinding wheels. Grit 60 offers a balance between aggressive material removal and surface smoothing, making it suitable for both shaping and preparing surfaces. The reinforced backing improves stability during use and supports safer operation at typical angle grinder speeds.

Suitable for

• Deburring edges and removing sharp burrs from cut metal
• Blending and smoothing weld seams on steel and stainless steel
• Rust, scale and paint removal from metallic surfaces
• Surface preparation before priming, painting or coating

Key specifications

• Diameter: 125 mm
• Abrasion level: grit 60 for medium-aggressive cutting
• Flap type: overlapping abrasive flaps on reinforced backing
• Suitable material: ferrous metals and stainless steel
• Mounting hole diameter compatibility: fits standard 22.23 mm (7/8") arbors
• Intended tool: angle grinders with compatible disc holder

How to use

Mount the flap disc on the angle grinder using the correct flange and ensure the disc is securely fastened. Verify the grinder speed does not exceed the maximum safe RPM for a 125 mm disc. Hold the grinder with steady pressure and move the disc across the workpiece with a consistent motion; avoid applying excessive force which can reduce flap life and cause uneven wear. For best results on welds, use moderate angles and overlapping passes until the desired blend and finish are achieved. Allow the abrasive to do the cutting rather than forcing the tool.

Usage recommendations

Use suitable personal protective equipment including eye protection, gloves and hearing protection when operating an angle grinder. Select grit 60 flap discs for tasks requiring a compromise between material removal speed and surface finish; for finer finishing, choose a higher grit number, and for faster stock removal use a coarser grit. Inspect the disc for damage before each use and replace if flaps are excessively worn or the backing is compromised.
