Soft to Medium Density Wheel Offers a Tougher Edge for Deburring and Blending
The Standard Abrasives™ Quick Change Aluminum Oxide (A/O) Unitized Wheel 600 Series has a soft to medium density when compared to other wheels in the Standard Abrasives™ Unitized Wheels line, and is designed with increased edge durability over 500 Series wheels. Constructed with fine grade (FIN) aluminum oxide, this double-duty abrasive combines durability with a fine scratch pattern, making it a great choice for smaller areas of the workpiece that require an aggressive cut yet soft finish — namely, tough blending and polishing applications.

Use a Standard Abrasives™ Quick Change A/O 600 Series Unitized Wheel for blending and refining surfaces of jet blade airfoil, blending parting lines from cast turbine blades and vanes, blending stainless steel surgical instruments, mill marks and machine mismatches and removing minor pits, scratches, resins/adhesive overspray, coating and plastic mold flashing.

Due to their conformability, these wheels are great for projects with strict tolerances, because they respond to surface irregularities.

Quick Change Wheels Increase Throughput
Standard Abrasives™ Quick Change Unitized Wheels are available in smaller sizes. Quick change wheels allow tool-free swap outs, maintain secure attachment at high speeds, and save operators time when switching discs between grades or applications. Easy fastening and swapping of wheels enhances tool efficiency and worker productivity.

TR quick change wheels have a nylon threaded male hub that easily threads onto a TR or 3M™ Roloc™ type holder pad (sold separately) so that operators can conveniently change discs with a simple twist-off, twist-on motion.
  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.

Unitized wheels are created by starting with layers of open web material that combines non-woven fiber strands and abrasive mineral with a tough resin bond. These layers of web are then cured and compressed together. By fusing layers of open web, the abrasive gains more toughness and durability, so it ca
