Abrasive Flap Disc KLINGSPOR SMT314 Extra 125 mm grit 36, MPN 322814

Abrasive flap disc KLINGSPOR SMT314 Extra 125 mm grit 36 is a 125 mm diameter sanding disc designed for use with angle grinders. The disc features a convex flap construction that ensures consistent material removal and uniform surface finishing on a variety of metals and weld joints. Intended for tasks such as stock removal, deburring and blending, this flap disc balances aggressive cutting with stable performance for metal fabrication, automotive repair and construction applications.

Advantages

The convex flap design delivers consistent contact with the workpiece for even stock removal and reduced chatter. Coarse grit 36 provides fast material removal while maintaining reasonable control over the finish. The disc construction offers long life under typical metalworking conditions and allows quick progression from rough shaping to blending without frequent disc changes.

Suitable for

• Removing weld beads and smoothing weld seams on steel and stainless steel
• Material stock removal on ferrous metals
• Deburring and edge blending after cutting or machining
• Surface preparation prior to welding or coating

Key specifications

• Disc diameter: 125 mm
• Abrasive grit: 36 (coarse)
• Flap design: convex construction for even contact
• Application: metal grinding, weld dressing, deburring and blending
• Compatibility: for use with standard 125 mm angle grinders

How to use

Mount the flap disc on a compatible 125 mm angle grinder according to the grinder manufacturer’s instructions, ensuring the correct mounting flange and secure fastening. Operate the grinder at the recommended speed range and apply moderate pressure, moving the disc steadily across the workpiece to avoid gouging. For best results on welds and heavy stock removal, use smooth, overlapping passes; reduce pressure and lighten strokes when approaching the desired surface finish.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves and respiratory protection for metal dust. Match grit and disc condition to the task: use grit 36 for aggressive stock removal and switch to finer grits when a smoother finish is required. Inspect the disc for damage before use and replace when worn or compromised.
