Standard Abrasives™ Type 27 Unitized Wheel, 811632, 632, Type 27, 4-1/2 in x 1/2 in x 7/8 in, Nylon, 5/Carton, 50 ea/Case

The Standard Abrasives Type 27 Unitized Wheel - 600 Series has a soft to medium density compared to the rest of the Standard Abrasives Unitized Block line. It is designed with increased durability over the 500 Series wheels. Constructed with fine grade silicon carbide, this double-duty abrasive combines durability with a fine scratch pattern. It is a great choice for projects that require an aggressive cut yet a soft finish, particularly tough blending and polishing applications.

When it comes to polishing, trust a Standard Abrasives 632 Unitized Wheel with silicon carbide. It is ideal for polishing aircraft parts, polishing after weld removal, and polishing mold and die, cast aluminum, brass, and copper. It is also a good match for finishing surgical instruments and prosthetics. When working with stainless steel, this wheel provides a clean and bright surface finish.

Due to its conformability, the Standard Abrasives Type 27 Unitized Wheel is great for projects with strict tolerances. It responds to surface irregularities without gouging or undercutting the part. Even after prolonged use, the wheel can be dressed to maintain its shape.

A 4-1/2 Type 27 Wheel, also known as a Type 27 Disc, is designed to fit a right angle grinder with a wheel guard. It is typically used for fiber discs, flap discs, and grinding wheels. Type 27 Wheels have a depressed center to allow grinding at any angle without damaging the surrounding surface. They are particularly useful for working on internal angles. These unitized wheels can be used in conjunction with, or sometimes in lieu of, a coated abrasive resin fiber disc or flap disc. Standard center hole and quick change unitized wheels are also available in a range of sizes (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. These wheels are designed with a far stronger and denser construction compared to Standard Abrasives Buff and Blend products. They can support more aggressive applications and accomplish material removal more rapidly. The non-woven nylon fibers of the wheel maintain the advantage of responding to surface irregularities while preserving the geometry of the piece, resulting in a consistent finish.

Standard Abrasives Unitized Wheels are load-resistant, allowing unwanted swarf to escape through the gaps in the open web. This reduces debris clogging the abrasive, keeping the mineral fresh and cutting sharp. As the fibers break down and fresh mineral is exposed, it reduces the likelihood of dull or blunt mineral smearing the surface. This contributes to cleaner surfaces and less re-work. The load-resistant construction also reduces manual fatigue that may result from applying heavy pressure to a dull abrasive.

Standard Abrasives Unitized Wheels offer many benefits for heavy-duty jobs. They invigorate deburring, cleaning, blending, and finishing applications by helping operators reduce finishing steps, minimize costs, and achieve greater throughput.
