Standard Abrasives™ 7000121901 632 Unitized Wheel, 4 in Dia Wheel, 1/4 in Center Hole, 1/4 in W Face, Fine Grade, Silicon Carbide Abrasive

Wheels in our Standard Abrasives™ silicon carbide unitized wheel 600 series have a soft to medium density, making them a good match for medium-pressure finishing and polishing on flat or contoured parts. Choose a 600 series wheel when your application calls for an upgrade in edge durability over a series 500 wheel. Our Standard Abrasives™ silicon carbide (S/C) unitized wheel 600 series has a soft to medium density when compared to other wheels in our Standard Abrasives™ unitized wheels line. Constructed with fine (FIN) grade silicon carbide, this double duty non-woven abrasive wheel combines durability with a fine scratch pattern, making it a great choice for projects that require an aggressive cut yet soft finish - namely, tough finishing and polishing applications. When it comes to polishing, trust Standard Abrasives™ S/C 600 series unitized wheel for polishing fillet areas on jet blades and aircraft parts, polishing after weld removal and polishing mold and die cast aluminum, brass and copper. It's also a good match for finishing of surgical instruments and prosthetics. Due to their conformability, these wheels are great for projects with strict tolerances, because they respond to surface irregularities. After prolonged use, the wheel can be dressed to maintain its shape. Unitized wheels are typically used on die grinders. A benefit of unitized wheels is that they are bi-directional and can be mounted on a tool or pedestal grinder without regard to the direction of the spindle rotation. This means the Standard Abrasives™ unitized wheel can be used with a variety of tools, and regardless of which way the workpiece is fed through the machine, the wheel will be able to respond, giving operators more flexibility. The stiffness of the unitized construction enables operators to use thinner wheels to access awkward angles with grinding tools. Series 600 wheels come in a range of diameters from 1 to 12 in and require a unitized wheel mandrel for attachment to the tool. Quick-change wheels are also available (sold separately). Standard Abrasives™ unitized wheels are a great match for tough deburring, cleaning, blending and finishing applications. They come in a broad range of densities and grades to suit different metals, the degree of aggressiveness required, shape of the part and desired finish. Although used for some of the same tasks as Standard Abrasives™ buff and blend products, they are designed with a far stronger and denser construction to support more aggressive applications and accomplish material removal more rapidly.
