Sanding disc 3M 7000034175 — 150 mm, aluminium oxide, for metal paint stainless steel wood

Sanding disc 3M 7000034175 is a 150 mm abrasive disc made with aluminium oxide, designed for use on metal, painted surfaces, stainless steel and wood. Intended for rotary tools, the disc delivers consistent material removal and surface preparation for grinding, deburring and finishing tasks in metalworking, painting preparation and carpentry. The product combines a durable abrasive grain with a backing suitable for standard 150 mm rotary sanding attachments.

Advantages

The aluminium oxide abrasive provides effective cutting and long life on a range of substrates including mild steel, painted panels, stainless steel and timber. Its 150 mm diameter fits common rotary sanding tools and supports even wear across the disc surface. The construction balances aggressiveness and control to allow both stock removal and surface finishing without frequent disc changes.

Suitable for

• Grinding and material removal on metal and stainless steel
• Paint preparation and paint removal on automotive and industrial panels
• Deburring and edge blending after cutting or machining
• Sanding and finishing wood surfaces in carpentry and joinery

Key specifications

• Abrasive material: aluminium oxide
• Diameter: 150 mm
• Compatible tool type: rotary sanding tools (150 mm backing)
• Primary application materials: metal, painted surfaces, stainless steel, wood
• Colour: green

How to use

Fit the 150 mm disc to a compatible rotary sander or backing plate according to the tool manufacturer's instructions. Start with moderate speed and light pressure to establish control and assess cutting rate, then adjust speed and pressure as needed for the material and desired finish. Move the tool with steady, overlapping passes to avoid gouging; for painted or coated surfaces, ensure proper ventilation and follow safety guidelines for dust and debris. Replace the disc when abrasive performance diminishes or if the backing becomes damaged.

Usage recommendations

For best results on metal and painted panels, begin with a coarser grit to remove material and follow with finer discs for smoothing. On stainless steel use light pressure and consistent motion to reduce heat build-up. When sanding wood, test on a scrap piece to confirm finish and adjust technique or grit accordingly. Always wear appropriate eye, respiratory and hand protection and observe the rotary tool's speed limits for 150 mm accessories.
