Why choose it

The EXPERT C470 line is engineered for high material removal rates and extended service life. The open-coated aluminum oxide abrasive resists clogging, while the calcium stearate coating reduces heat buildup and improves finish quality. The triangular shape reaches into corners and edges that round or square sheets cannot, making it a versatile choice for detailed sanding tasks.

Ideal use cases

• Sanding wooden surfaces before painting or varnishing
• Removing old paint, varnish, or filler from flat and contoured areas
• Preparing furniture, doors, and window frames for refinishing
• Working on multi-sanders where triangular sheets are required

Good to know

These sheets are designed for use with Bosch multi-sanders and other compatible tools featuring a hook-and-loop pad and dust extraction. The K60 grit is coarse; for finer finishing, consider higher grits in the same series. Always ensure the tool's dust extraction is connected to maximize the benefits of the six-hole pattern.
