Description
3M 7100147541 is a clean sanding abrasive disc engineered for high-productivity automotive and metalworking applications. This 3-inch 3M Cubitron 737U employs 3M precision-shaped ceramic grain to provide fast, consistent material removal while reducing operator force and extending disc life. The triangular-shaped PSG cuts cleanly through paint and body filler, making this disc ideal for paint removal, rough shaping, and final feather-edging prior to priming. Its multi-hole Clean Sanding pattern enhances dust extraction and works with Clean Sanding pads for central vacuum or extractor use. Hookit attachments make change-outs in production or repair workflows easier, reducing downtime and keeping the workspace cleaner. The 3M sanding discs in 3-inch size balances access to confined areas with strong cutting performance for both repair shops and production lines.
Product Features and Benefits
Precision-shaped ceramic grain for fast cutting
Triangular PSG technology slices material rather than ploughing, delivering up to 30% faster cut rates and a consistently sharp cutting surface for longer life.
Clean Sanding hole pattern for dust control
The multi-hole layout evacuates dust efficiently to increase cut rate and disc life and works with 3M clean sanding abrasive discs for extractor-ready sanding systems.
Hookit hook-and-loop attachment
The 3M 31361 Hookit system enables rapid disc changes and secure mounting on Hookit backup pads, improving operator throughput and reducing rework times.
C-weight backing for durability
Robust C-weight paper backing provides support for aggressive grinding while retaining flexibility for contour work on automotive panels.
Optimised for paint removal and feather-edging
The 3M Cubitron 737U is intended for paint removal, body filler shaping, and final prep before priming, with consistent performance at each prep stage.
