With the Bosch J450 Expert for Wood and Paint sanding roll, you can smoothly finish curved surfaces and intricate contours without the backing tearing. Its flexible J-cloth base contours effortlessly to complex shapes, while the semi-friable aluminium oxide grit delivers a uniform removal rate across solid wood, paint, lacquer, and veneer. The fine P180 grit makes keying between coats and preparing surfaces for final finishing easy and controlled. Measuring 115 mm wide and 50 m long, this roll tears cleanly to your required size for manual hand sanding, sanding blocks, or clamped orbital sanders.
