Flap disc KLINGSPOR SMT314 EXTRA 125 mm grit 80 for angle grinders

Flap disc KLINGSPOR SMT314 EXTRA 125 mm grit 80 is an abrasive accessory for angle grinders intended for metalworking tasks. The disc combines overlapping abrasive flaps arranged on a backing plate to deliver controlled material removal, surface blending and light deburring. With a 125 mm diameter and medium-fine abrasive grit 80, it balances stock removal rate and surface finish, making it suitable for smoothing weld seams and preparing steel and stainless steel surfaces prior to finishing.

Advantages

The flap design provides consistent cutting action while conforming to contours, which reduces gouging and delivers a more even surface. Grit 80 offers a compromise between material removal and surface quality, enabling efficient blending of welds and removal of minor imperfections. The disc is compatible with standard 125 mm angle grinders and is designed to be exchangeable quickly to support workflow continuity.

Suitable for

• Grinding and blending weld seams on steel and stainless steel
• Light deburring of metal edges and profiles
• Surface preparation before painting or coating
• Matting and smoothing of metal surfaces

Key specifications

• Diameter: 125 mm
• Abrasive grit: 80 (medium-fine)
• Design: overlapping abrasive flaps on backing plate
• Intended use: metal and stainless steel
• Compatibility: fits standard 125 mm angle grinders

How to use

Secure the flap disc to the angle grinder according to the grinder manufacturer’s instructions and ensure the tool is unplugged or its battery removed during mounting. Operate the grinder at recommended speeds and apply moderate, even pressure while moving the disc across the workpiece to avoid excessive heat and premature wear. Use steady, overlapping passes when blending welds or smoothing surfaces, and allow the abrasive flaps to wear progressively to maintain a uniform finish. Replace the disc when abrasive performance declines or when damage is visible.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves, and hearing protection. Use the disc within the angle grinder's rated speed and follow workplace safety practices. For best results on stainless steel, use light pressure and avoid prolonged dwell in one spot to minimize discoloration.
