Product Benefits

  • 4-1/2 Type 27 center hole wheel fits 4-1/2 right angle grinder to help reach right angles on the workpiece
  • Soft density silicon carbide wheel blends surfaces to a fine finish
  • Soft density offers exceptional conformability for applications with close tolerances
  • Cuts faster than Standard Abrasives™ Buff and Blend non-woven products, though with less flexibility
  • Silicon carbide mineral suits ferrous and non-ferrous metals, including exotic metals and titanium, as well as composites
  • Runs clockwise and counterclockwise, allowing greater versatility
  • Open web is load resistant, contributing to longer abrasive service life
  • Non-woven nylon strands will not melt or smear when heated, reducing potential for unwanted marks and blemishes

Soft Density Silicon Carbide Wheel Polishes with Precise Results
Among Standard Abrasives™ Unitized Wheels, the 500 Series provides the softest density, and is available in medium (MED) and fine (FIN) grade silicon carbide (S/C). The Standard Abrasives™ Type 27 Unitized Wheel - 500 Series combines soft density and sharp-cutting S/C mineral, making these wheels a good match for applications where a fine finish is more important than cut, such as polishing soft metals prior to the coating process. Due to their conformability, these wheels are great for projects with strict tolerances, because they respond to surface irregularities without gouging or undercutting the part. After prolonged use, the wheel may be dressed to maintain its shape.

Choose the Right Wheel for Your Finishing Application
Standard Abrasives™ 500 Series includes two Type 27 Wheels:

Wheel 532

  • Fine grade silicon carbide
  • Requires light pressure for fine finishing and polishing
  • Highly conformable
  • Provides clean, bright surface finish on stainless steel
  • Best when run at slower speeds for fine finishes


Wheel 524

  • Medium grade silicon carbide in a denser configuration
  • Similar to Wheel 532, but with extra layer for durability
  • Provides greater rigidity than Wheel 532, for more precise finishing applications
  • Higher cut and finishing rate than Wheel 532
  • Ideal for high contact pressure applications where cut rate and durability are important


Type 27 Fits 4-1/2" Right Angle Grinder
A 4-1/2" Type 27 Wheel (sometimes called a Type 27 Disc) is designed to fit a right angle grinder with a wheel guard, 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 with the attachment nut, and are particularly useful for working on internal angles. These unitized wheels are used in conjunction with, and 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).

Non-Woven Unitized Construction Offers a Step Up in Density and Durability for Stubborn Surfaces
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. Even though unitized wheels are much stiffer products, the non-woven nylon fibers of the wheel maintain the advantage of responding to surface irregularities while preserving the geometry of the piece, and produce a consistent finish.
