These 115mm flap discs fit your 4.5-inch angle grinder or disc sander. They combine grinding and finishing in one step. They have zirconia alumina grain and cut quickly on metals like steel and stainless steel. The T27 flat design gives you full surface contact for clean, flat results.
Features and Benefits
- Zirconia abrasive - This grain sharpens itself, cuts fast, and lasts longer than regular aluminum oxide discs.
- T27 flat profile - Gives a large, flat contact area, which is good for grinding welds and blending on flat surfaces.
- Fiberglass backing plate - Reduces vibration for smoother use and provides a strong, stable base for the flaps.
- Different grit options - Available in 40, 60, 80, and 120 grits to handle heavy material removal or fine surface finishing.
Applications
- Weld grinding and blending - A 40 or 60 grit disc quickly takes down weld beads and blends them into the metal around them.
- General metal preparation - The 80 grit flap disc is a solid choice for removing rust, cleaning edges, and general surface conditioning.
- Finishing and deburring - Use a 120 grit disc for light deburring and to leave a smooth, paint-ready finish on steel or aluminum.
Ray L. Carter (Stationary/Industrial Disc Sander)
The disc sander, an invention attributed to Ray L. Carter, plays a crucial role in workshops for shaping and finishing various materials. These Heavy-Duty Disc Sander Flap Wheels, with their Zirconia material and 115mm diameter, are ideal for such applications. A stationary disc sander typically operates at speeds like 1725 rpm or 3450 rpm, providing consistent material removal. When working with a disc sander, it is essential to ensure proper dust extraction to maintain a clear workspace and for safety. The 60 Grit on these flap wheels is suitable for general material removal and surface preparation.
Alex A. Clarke (Portable Specialty Sanders)
Alex A. Clarke is credited with developing portable specialty sanders, making sanding more versatile and accessible for various tasks. A disc sander is a power tool used for abrading surfaces, typically for material removal or finishing. These Zirconia flap wheels, compatible with angle grinders and disc sanders, offer flexibility for both workshop and on-site work. The 115mm diameter makes them suitable for a range of portable tools. When using a portable disc sander, choose the correct grit for the job; the 60 Grit offered here balances aggressive removal with a finer finish than 40 Grit.
Arthur N. Emmons (Modern Portable Handheld Disc Sander)
The evolution of portable disc sanders continued with innovators like Arthur N. Emmons, leading to the modern handheld disc sander designs used today. These tools are commonly used for tasks like paint removal, rust removal, and surface smoothing. Our Heavy-Duty Disc Sander Flap Wheels, with their T27 type, are designed for such applications. The Zirconia abrasive provides durability and efficient material removal. The 60 Grit is a versatile choice, offering a good balance between aggressive cutting and preparing surfaces for subsequent finer sanding with, for example, 120 Grit discs.
