Soft to Medium Density Wheel Offers Multi Purpose Utility
Our Standard Abrasives™ Aluminum Oxide (A/O) Unitized Wheel 600 Series has a soft to medium density when compared to other wheels in our Standard Abrasives™ Unitized Wheels line, and is designed with increased edge durability over our 500 Series wheels. Constructed with fine grade aluminum oxide, this double duty abrasive combines durability with a fine scratch pattern, making it a great choice for projects that require an aggressive cut yet soft finish – namely, tough blending and polishing applications.

Use our Standard Abrasives™ 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. After prolonged use, the wheel can be dressed to maintain its shape.

Compatible with a Variety of Tools
Unitized wheels are typically used on a right angle grinder. 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 comes in a range of diameters from 1 12˝ and require a unitized wheel mandrel (sold separately) for attachment to the tool. Quick change wheels are also available (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.

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 can withstand repeated wear.

Ultimately, the wheel's durability is what makes it such a good match for edges. Regardless of the diameter or thickness of the wheel, it maintains its structural integrity to remain a stiff and long lasting abrasive. Additionally, as the layers wear, the wheel can be dressed to maintain its shape.
