3/8 X 13 Inch Premium Zirconia Air File Sanding Belts, 10 Pack

3/8x13" Industrial Grade Zirconia Grinding BeltsOur industrial grade zirconia sanding belts are a great choice for heavy duty grinding applications. Zirconia’s self-sharpening abrasive grains extend belt life up to 2.5 times longer than aluminum oxide. Zirconia fractures during use, continuously revealing sharp abrasive grain. Its durability and quick cut makes it a great choice for welders or anyone working with metals. We use a special heavy but flexible backing for tight contours of hand held air sanders. Hand built in the USA. Fits: 3/8" x 13" air belt sanders (air file sanders), such as the Ingersoll Rand 360-313 and Astro 3036.
