Effective and elastic - the flexible cotton backing with closely coated aluminium oxide

Its flexible cotton backing allows it to contour snugly to the workpiece at hand. These properties allow every skilled craftsman to achieve sanding results of flawless quality with this belt. The J-weight cotton for the backing of this product is flexible, yet exceedingly stable and tear-resistant at the same time. The aluminium oxide grain is applied to this backing with a close coating. This ensures that the backing is almost entirely covered by abrasive grain. Aluminium oxide is distinguished by its combination of ruggedness and toughness. What is more, the close coating of the abrasive grain ensures a uniform scratch pattern as it spreads the applied force across a large number of grain points. This coating is responsible for the uniform and finely structured surface the product leaves behind on wood and wood-based material.

    Tools have been high quality and work great!! Will continue to get tools from here. I think there would also be a market for skookum chamfer mills, threadmills, and other "specialized" tooling. ..

    Ordered 3 band saw blades and they arrived very quickly - within the week from manufacture. Have only used one so far and is very good. The only con I have is the twisting tension at the weld. ..

    We ordered a roll of graphite and two graphite mitts. The products were as described and shipped expeditiously. If possible, it might be a good idea to develop a mitt with a heavy-duty wrist cuff. We use a wrist protector with the mitt because of the danger of the mitt slipping off the belt and..

    Impressed by the quick response to inquiries. Only downside was not any fault of store, postal rotating strikes delayed shipment. Will definitely reorder as need arises and have recommended to others that this is the place to be looking to order from. Keep up the great customer service. ..
