3M 7100141921 – SCOTCH-BRITE™ SURFACE CONDITIONING DISC, SC-DH, A CRS, 7 IN X NH (17.78 CM X NH)

The Scotch-Brite™ Surface Conditioning Disc comes in a wide variety of grades and sizes and is an ideal first step for cleaning, blending, deburring, and finishing. The disc's durable, non-woven fibre construction conforms well on irregular or contoured surfaces without undercutting or damaging the base material, and the open web construction resists loading. This popular abrasive is available with aluminum oxide and silicon carbide minerals.

Details

• Available in a variety of abrasive types (aluminum oxide or silicon carbide), grades, and sizes;
• Conformable disc conditions surfaces without gouging, undercutting, or damaging the base material;
• Ideal first step for cleaning, finishing, blending, and light deburring jobs;
• Suitable for use on metal, composite, plastics, and other materials

The Scotch-Brite™ Surface Conditioning Disc features an open-web material that helps the disc run cool and resists loading. Interspersed aluminum oxide or silicon carbide abrasives produce a high cut-rate for consistent finishing. Aluminum oxide is a popular choice among industrial professionals because of its cut-rate and long life. This mineral is a tough, durable abrasive that self-fractures to expose fresh cutting edges in use, whereas traditional abrasives, such as garnet, quickly wear down with use. Due to its high cut-rate, hardness, strength, and low heat retention, aluminum oxide mineral is widely used in grinding applications in addition to sanding and finishing use. Silicon carbide is tougher than aluminum oxide, but it breaks down more quickly. Silicon carbide is ideal in applications requiring a fine, smear-free finish.
