Flap Disc KLINGSPOR SMT314 Extra 125 mm grit 40 (MPN 322815)

Flap Disc KLINGSPOR SMT314 Extra 125 mm grit 40 is a coated abrasive disc for angle grinders, engineered for efficient material removal and controlled finishing on metal and similar substrates. The convex, multi-layered flap layout maintains consistent contact with the workpiece, allowing uniform stock removal and improved surface quality during grinding, deburring and edge blending operations. The 125 mm diameter fits standard handheld angle grinders, making this flap disc suitable for both workshop and light industrial use.

Advantages

The KLINGSPOR SMT314 Extra offers balanced cutting performance and lifespan due to its overlapping abrasive flaps and a resilient backing that tolerates moderate flexing. Grit 40 provides an aggressive cut rate for fast removal of weld seams, scale and excess material while still enabling controlled surface conditioning. The convex geometry reduces gouging and promotes smoother transitions when working on curved or contoured edges. The disc's construction contributes to stable grinding behavior and predictable results across repeated use.

Suitable for

• Grinding and shaping steel and iron surfaces
• Weld seam dressing and removal of weld spatter
• Deburring and edge blending on fabricated metal parts
• Surface preparation before painting or coating
• Removing scale, rust and minor corrosion

Key specifications

• Disc diameter: 125 mm
• Abrasive type: flap-style coated abrasive
• Grit size: 40 (coarse)
• Profile: convex (curved) flap arrangement
• Compatible tool: angle grinder with appropriate guard and RPM rating

How to use

Mount the 125 mm flap disc securely on an angle grinder that supports this diameter and respect the tool manufacturer's maximum RPM. Wear appropriate personal protective equipment including eye protection, gloves and hearing protection. Begin grinding with light to moderate pressure, keeping the disc at an angle appropriate for the task (typically 10–30° for surface removal and blending). Move the disc steadily across the workpiece to avoid concentrated heating or gouging; allow the abrasive flaps to do the cutting rather than forcing heavy pressure.

Usage recommendations

For best results, use the KLINGSPOR SMT314 Extra on clean, dry metal surfaces and check the angle grinder's speed compatibility before operation. Replace the disc when wear reduces cutting efficiency or when flap damage occurs. Store discs flat in a dry environment away from extreme temperatures to preserve abrasive performance.
