The Standard Abrasives™ Type 27 Unitized Wheel - 800 Series is a highly aggressive wheel that is perfect for high-pressure applications. It is made with a coarser mineral and greater material density, making it ideal for deburring stainless steel pipe thread, wire edges from surgical instruments, stainless steel sinks, tanks, and other equipment for the food service industry. It is also great for deburring gears and aircraft wing spars, and breaking edges on aluminum extrusions. Additionally, it is effective in polishing stainless steel rule dies, welds on stainless steel sinks, machined surfaces, hand tools, and round tubing.
Choose the Right Wheel for Your Stock Removal ApplicationThe Standard Abrasives™ 800 Series includes three Type 27 Wheels:
- Wheel 811
- Coarse grade aluminum oxide mineral
- Highest stock removal and edge breaking capability
- Most aggressive for deburring
- Capable of replacing 80 & 120 grit coated abrasive discs
- Wheel 821
- Medium grade aluminum oxide mineral
- High stock removal, while maintaining disc life and productivity
- Very durable on an edge
- Capable of replacing 100 & 120 grit coated abrasive discs
- Wheel 822
- Medium grade silicon carbide mineral
- Rapid stock removal, while providing a clean, bright surface
- Most effective on stainless steel
- High cut rate, with long life
A 4-1/2˝ Type 27 Wheel 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 SurfacesStandard 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. The wheel is tough enough to complete high-pressure edgework without tearing or otherwise disintegrating. Regardless of the diameter or thickness of the wheel, it maintains its structural integrity to remain a stiff and long-lasting abrasive even under high pressure. Additionally, as the layers wear, the wheel can be dressed to maintain its shape.
Load-Resistance Boosts Life and PerformanceStandard 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.
The Many Benefits of Standard Abrasives™ Non-Woven ProductsStandard Abrasives™ Unitized Wheels offer many benefits for heavy-duty jobs. For all the aforementioned reasons, Standard Abrasives™ Unitized Wheels invigorate deburring, cleaning, blending, and finishing applications by helping operators reduce finishing steps, minimize costs, and achieve greater throughput.
