RS PRO 4 mm Refill Fibreglass

RS PRO 10 x 4 mm Glass Fibre Refills

Use these RS PRO refills with your 4 mm pencil to sand or clean hard-to-reach surfaces. Made with abrasive glass fibre bristles, these refills are suitable for removing pencil marks and paint or smoothing rough surfaces. The slim design makes it easier to work on small or narrow areas such as wood grooves and the inside of pipes.
They're simple to use – simply insert a refill into your pencil and twist to increase or decrease the tip size. Glass fibre refills also come in sizes from 2 mm to 8 mm, to fit your retractable sanding pencil.
Plumbers and engineers use these abrasive refills to remove rust, grease and burrs from metal ready for soldering. Jewellery-makers, hobbyists and woodworkers also find this tool handy for preparing and finishing wood and metal. These refills come in a pack of ten, so you can keep your pencil topped up on larger projects.
