Standard Abrasives™ Quick Change TR A/O Unitized Wheel 863198, 631 3 in x 1/4 in, 10 ea/Case

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.

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.

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.

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.

Standard 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.

• Soft/Medium density wheel blends surfaces to a nice finish
• Increased edge durability over the 500 Series offers better cut and adds life for light deburring and blending applications
• Aluminum oxide mineral is a good match for ferrous and non-ferrous metals, including aluminum
• Open web is load resistant, contributing to longer abrasive service life
• Easy fastening and swapping of TR style quick change disc enhances tool efficiency and worker productivity
