Abrasive Disc KLINGSPOR SMT 624 125 mm grain 120 — sanding disc for metal and wood

Abrasive Disc KLINGSPOR SMT 624 125 mm grain 120 is a multi-purpose sanding disc designed for use on metal and wood. With a 125 mm diameter and medium-fine 120 grit abrasive, this disc is suitable for material removal, surface preparation, and smoothing tasks. It fits hand grinders and angle grinders that accept 125 mm discs and is intended for workshop and industrial applications where consistent abrasion and controlled stock removal are required.

Advantages

The KLINGSPOR SMT 624 disc provides uniform cutting action and stable performance thanks to its balanced abrasive structure. Its 120 grit delivers a medium-fine finish that reduces surface roughness while preserving profile shape and edges. The disc is compatible with common 125 mm grinding tools and offers reliable durability for repeated use in deburring, rust removal, and intermediate sanding prior to painting or coating.

Suitable for

• Material removal and surface preparation on steel and non-ferrous metals
• Sanding, smoothing, and leveling wooden surfaces
• Deburring and edge blending on fabricated parts
• Rust and scale removal before priming or painting
• Intermediate sanding between coats or prior to finishing

Key specifications

• Disc diameter: 125 mm
• Abrasive grit: 120 (medium-fine)
• Intended materials: metal and wood
• Tool compatibility: hand grinders and angle grinders for 125 mm discs
• Primary applications: sanding, deburring, rust removal, surface preparation

How to use

Mount the abrasive disc on a compatible 125 mm grinder following the tool manufacturer’s mounting instructions and safety guidelines. Use appropriate rotational speed as recommended for the disc and the material being worked. Apply steady, even pressure and move the grinder across the surface to avoid concentrated heat or gouging. Replace the disc if wear reduces cutting efficiency or if damage is observed.

Usage recommendations

Use suitable personal protective equipment including eye protection, gloves, and hearing protection. For best results on metal, start with a coarser grit if heavy material removal is needed, then finish with the 120 grit KLINGSPOR SMT 624 for a consistent medium-fine surface. On wood, test on a scrap piece to verify desired surface finish and avoid excessive pressure that can cause burning or tear-out.
