Standard Abrasives™ Type 27 Unitized Wheel, 811732, 732, Type 27, 4-1/2 in x 1/2 in x 7/8 in, Nylon, 5/Carton, 50 ea/Case

The Standard Abrasives Type 27 Unitized Wheel - 700 Series is a highly effective choice when you need to achieve both an aggressive cut and a fine finish. With its medium to hard density, this wheel is specifically designed for finishing edges and internal angles on various materials such as titanium, composites, stainless steel, and steel alloys.

The 4-1/2 Type 27 Wheel, also known as a Type 27 Disc, is designed to fit a right angle grinder with a wheel guard. This type of wheel is commonly used for fiber discs, flap discs, and grinding wheels. The Type 27 Wheel features a depressed center, allowing for grinding at any angle without damaging the surrounding surface. It is particularly useful for working on internal angles. Standard center hole and quick change unitized wheels are also available in various sizes.

Standard Abrasives Unitized Wheels are specifically designed for tough deburring, cleaning, blending, and finishing applications. These wheels come in a wide range of densities and grades to suit different metals, required aggressiveness, part shapes, and desired finishes. Unlike Standard Abrasives Buff and Blend products, Unitized Wheels have a stronger and denser construction, allowing for more aggressive applications and faster material removal. The non-woven nylon fibers of the wheel respond to surface irregularities while maintaining the geometry of the piece, resulting in a consistent finish.

Unitized wheels are created by layering open web material that combines non-woven fiber strands and abrasive mineral with a tough resin bond. These layers are then cured and compressed together, providing the wheel with increased toughness and durability. This allows the wheel to withstand repeated wear and maintain its structural integrity, making it ideal for high-pressure edgework without tearing or disintegrating. The wheel can also be dressed to maintain its shape as the layers wear.

Standard Abrasives Unitized Wheels are designed to be load-resistant, ensuring a consistent cut throughout the life of the product. The gaps in the open web structure allow unwanted swarf to escape, preventing debris from clogging the abrasive. This keeps the mineral fresh and sharp, reducing the likelihood of dull or blunt mineral smearing the surface. As the fibers break down and expose fresh mineral, cleaner surfaces are achieved, resulting in less re-work. Additionally, the reduced manual fatigue from applying heavy pressure to a dull abrasive contributes to improved performance.

Standard Abrasives Unitized Wheels offer numerous benefits for heavy-duty jobs. By reducing finishing steps and minimizing costs, these wheels invigorate deburring, cleaning, blending, and finishing applications. They provide operators with greater throughput and help achieve high-quality results.
