Our extra hard Standard Abrasives™ Quick Change Ceramic 900 Series Unitized Wheel is the fastest-cutting, most aggressive wheel in our unitized wheel line. When productivity is the bottom line, this heavy hitter offers swift results, a smooth feel, and outstanding control, making it a smart solution for tough blending and deburring applications.

Standard Abrasives™ Silicon Carbide Unitized Wheel - 800 Series
Fast, Easy Weld Blending and Deburring
The combination of density and coarse mineral enables this wheel to withstand high-pressure applications and cut with force, making it suitable for a variety of operations. Whether tackling a 90° weld or blending on inner or outer diameters, you can rely on our Standard Abrasives™ Quick Change Ceramic 900 Series Unitized Wheel for fast action and a consistent finish. With unitized non-woven construction, the wheel runs smoothly over the part and allows the operator greater control over the results. Efficient results and ease of operation combine to provide a great productivity boost.

Our 900 Series wheel is engineered with the highest level of toughness and edge durability for effective removal of challenging burrs. The added cutting power of ceramic grain along with the consistent performance of non-woven material helps operators quickly tackle a wide range of tough deburring applications.

Use our Standard Abrasives™ 900 Series Quick Change Ceramic Unitized Wheel on smaller areas of the workpiece for removal of flash and parting lines, deburring sharp edges for a clean radius, removal of coarse coated abrasives grind lines and removal of heavy machine tool marks. When it comes to blending, trust this wheel to blend pits or cast parts and blend machined surfaces where wheel rigidity is necessary.

Ceramic Grain, Rapid High-Pressure Stock Removal
Ceramic abrasives are engineered with high levels of hardness and strength so they can efficiently perform rapid stock removal and handle intense heat and stress applications. They perform best under high pressure.

Quick Change Convenience
Our Series 900 Ceramic Wheels are available in smaller sizes with a TR attachment and allow tool-free swap outs, maintain secure attachment at high speeds, and save operators time when switching discs between grades or applications. TR wheels have a nylon threaded male hub that easily threads onto TR or 3M™ Roloc™ type holder pads with a turn of the wrist. All Standard Abrasives™ TR Holder Pads have a 1/4-20 female thread. A 1/4" TA4 mandrel attaches the holder pad to the tool (sold separately, PN 540013).

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. 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.

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 even under pressure. Additionally, as the layers wear, the wheel can be dressed to maintain its shape.

Load-Resistance Boosts Life and Performance
Standard Abrasives™ Unitized Wheels are load-resistant to keep you cutting with fresh mineral. The gaps in the open web allow unwanted swarf to escape. Consequently, less debris clogs the abrasive, so the mineral can stay fresh, keep cutting sharp and deliver a consistent cut over the life of the product. As the fibers break down and fresh mineral is exposed, it reduces the likelihood of dull or blunt mineral smearing the surface, contributing to cleaner surfaces and less re-work. Furthermore, manual fatigue that may result from applying heavy pressure to a dull abrasive is reduced.

Quality Standard Abrasives™ Solutions for Industrial Applications
For all the aforementioned reasons, Standard Abrasives™ Unitized Wheels invigorate deburring, cleaning, blending and finishing applications by helping operators reduce the need for rework, minimize costs and achieve greater throughput.

The Standard Abrasives™ brand has supplied quality abrasives to the metalworking industry for over 50 years. Customers rely on our broad offering of high performance products including coated, bonded, and non-woven abrasive lines.
