150 Grit Aluminum Oxide, 12 in. PSAdhesive Sanding Disc - Qty:5

150 Grit Aluminum Oxide, 12 in. Pressure Sensitive Adhesive Sanding Disc - QTY:5

Production Shops Take Note - No cheap materials used here!

Our PSA (pressure sensitive adhesive) discs are made of full resin bonded Aluminum Oxide, heavy cloth backed material along with an adhesive that holds fast yet does not gum up your backing pad. Ideal for production situations that require discs to hold fast at high speeds and for repetitious, single-grit sanding of flat surfaces. Our competitors often use inferior materials or scrap in the manufacture of their discs. KLINGSPOR provides only high-quality industrial products. The broader grit range allows you to achieve the perfect finish every time. Each pre-glued disc attaches in seconds; simply peel off the backing paper, stick it on, and sand.

These discs are manufactured from our premium Aluminum Oxide material for wood sanding operations where clogging or loading is a problem. Also great for sanding of soft metals such as brass or bronze.

Aluminum Oxide (AO)

AO is formed by combining bauxite and other materials by firing them in an electric furnace. The resultant mass is then crushed, and the pieces sifted through successively finer screens to assign a grit size (CAMI grading). When crushed, the resulting pieces are naturally pyramidal in shape. Due to the shape and the strength of the materials used in its making, AO is a very durable grain. The grain is worn down during use, sanding finer the longer it's used.

AO is very tough and durable, as stated above, and is used on bare wood, most metals (especially the steels), leather and a wide variety of other materials. It is a great general purposes grain and probably the most, common grain seen today.

Cloth Backing

There are 3 basic weights of cloth backings: J, X and Y. J and X are cotton materials. The J has a slight degree of conformability to it and should be used where a small degree of conformability to the workpiece is needed in belts or sheets. The X is heavier weight cotton and is an all-purpose/general purpose backing used in a wide variety of belting applications including portable belts, intermediate belts and wide belts. Y backings are 100% polyester (or in some cases a 60/40 poly/cotton split) and are used for flat, heavy duty dimensioning or other high heat or rough applications. The J and X weight backings have flexed versions available that are referred to as J-Flex (JF) and X-Flex (XF). These would be suitable for applications where the X or J is not quite flexible enough.

Semi Open / Open Coat

  1.) semi-open and open coat products will cut less aggressively

  2.) semi-open and open coat products will finish coarser per grit than closed coat products.

Semi-open and Open coat products have less grain on the backing, which results in less cutting power per grit designation.

Semi-open and Open coat products have gaps in their grain coverage, so the finishes they provide will not be as even and will fall to the coarse end of the designated grit's finishing parameters.
