These multi-sanding sheets have a perforated tear off delta sheet for detail sanding (102 x 62mm, 93mm). They are made from aluminium oxide that is resin bonded to provide improved grain adhesion, anti-static qualities and long-lasting performance. The heavy-duty E-Weight backing paper makes the sanding sheet more durable –– able to withstand the toughest jobs. The hook and loop backing offers decent adhesion to facilitate the fast changing of sanding sheets. The 11 pre-punched 8mm holes help eliminate clogging and improve the dust extraction. Ideal for sanding and finishing wood, metal, aluminium alloy, painted surfaces, plastic and fillers. Compatible with most mouse detail sanders with hook and loop backing pads including Draper Stock No. 57681.
