Norton Blaze R980P Abrasive Flap Disc, Type 27, Threaded Hole, Plastic Backing, Ceramic Aluminum Oxide, 4-1/2 Dia., 80 Grit (Pack of 1)

Norton Blaze R920 type 27 abrasive flap discs are suitable for blending and smooth finishing on stainless steel, cobalt, chrome, titanium and other hard-to-grind materials. Flap disc design is suitable for use on right-angle grinders or vertical-shaft portable grinders. The cloth backing is stiffer, tougher, and thicker than a paper or film backing. The cloth resists tearing while bending and flexing during use, providing smooth blending and finishing and is ideal for low- to medium-pressure applications.

With a type 27 flap disc, hold the grinder in operation at an angle less than fifteen degrees to the work surface. Steeper angles will weaken the flap edges. The weight of the backing is designated by letters J, X, Y, T or M. J is the lightest and M is the heaviest. A more flexible backing will follow irregular contours of a workpiece better than a stiffer one. Stiffer backing is more suited for regular round or flat surfaces.

Coated abrasives have individual abrasive grains spaced at a predetermined distance from one another. This is a closed-coat disc. A closed coat covers 100 percent of the surface with abrasive grains, for more stiffness and better surface finish than an equivalent open coat, where abrasive grit covers 50 to 70 percent of the surface. This disc features a resin bond. Resin bonds have good moisture resistance, are harder and less flexible than glue bonds, and have good heat resistance and grain retention. Resin bonds are useful for abrasive operations with high operating speeds, impact, and sudden loading, as the resin bond is strong and can withstand rough treatment. Use with molded rubber back-up pads, using a hard pad for aggressive cutting, a medium pad for general purpose applications, or a soft pad for contours and fine finishing work.

Ceramic aluminum, sometimes called ceramic alumina, is tougher than aluminum oxide, and is self-sharpening. It is formed in a process where alumina gel is dried and then crushed. These engineered crystals fracture and refracture at fine levels, to form a smooth, self-sharpening abrasive material. Ceramic aluminum oxide is most commonly used for medium-to-high material removal on metals.

Abrasives are used for a variety of applications from shaping a part to fine finishing, depending on the grit size. Low grit numbers like 40 are coarse and are used for removing excess material and shaping a part. High grit numbers like 400 are fine and help to create a smooth surface finish.

Norton Abrasives manufactures a wide variety of sanding, sanding, and polishing abrasives, and has been located in the United States since 1885. In 1990, Saint-Gobain purchased Norton, keeping its manufacturing facilities and offices in the same location. Norton/Saint-Gobain has been recognized as a Global 100 Sustainable Company, as well as earning ISO 9000 and 14001 certification for quality and environmental management standards.

the radiator keeps your vehicle's engine cool during a drive; but when your radiator is leaking coolant, the engine can overheat and suffer serious damage. if you are far from a garage and your radiator is leaking, you can use eggs to patch small holes and temporarily plug the leaks. heat from the radiator will cook the egg whites, and pressure will force the eggs into the holes, fixing the leaks long enough to take your car to a garage for repairs.

allow the radiator to cool. test the temperature of the radiator by carefully touching the radiator hose; do not continue if the radiator hose is still hot.

step 2

cover the radiator cap with a towel or rag, and slowly twist the cap to open the radiator. let any steam dissipate before fully opening the radiator.

step 3

crack an egg gently into two halves over the bowl. pour the yolk back and forth between the shell halves, and let only the white run into the bowl.

step 4

pour the egg white from the bowl into the radiator.

step 5

repeat steps 3 and 4 for the remaining eggs. separate and pour the whites into the radiator one at a time; if you spill the yolk, you won't ruin all of the whites.

screw the cap radiator cap back into place, and make sure it is secure before starting your car.
