Benefits of Flap Disc
Excellent versatility
Flap discs allow you to grind, bend and finish with a single tool. They are ideal for applications from woodworking to concrete grinding or finishing.
Improved maneuverability
A flap disc is a lightweight and easy-to-use solution, allowing grinders to complete tasks faster and more accurately.
Reduced noise and vibration
Worker safety and comfort are paramount in environments requiring abrasive materials. Abrasive flap discs are quieter and vibrate less, making them safer and more comfortable for your team.
Extended operating life
Flap discs require less change over time and remain functional after the flaps wear, which means a longer operating life. This durability results in long-term cost savings..
What Types of Flap Discs Do We Have?
Long Life Sanding Flap
A flap disc is an abrasive disc designed to work with angle grinders and die grinders. They are made up of overlapping coated abrasive flaps attached radially to a backing plate often made up of fiberglass or plastic and featuring either an open center hole, screw on-screw off hub, or quick change attachment.
Flap Inox
Flap Inox is a versatile abrasive flap disc that is made from stainless steel, providing an exceptional level of resistance to corrosion and wear. It is specifically designed for use in the metal fabrication, construction, and manufacturing industries to grind, finish, and polish a range of materials including stainless steel, aluminum, and other metals.
Zirconium Disc
One of the main advantages of our zirconium discs is their high-temperature resistance. Zirconium is a highly stable material that can withstand high temperatures without degrading or losing its structural integrity. This makes our discs ideal for use in high-temperature applications such as heat exchangers, furnaces, and other high-temperature industrial processes.
4.5 Inch Flap Disc
Our 4.5 Inch Flap Disc is made from high-quality abrasive materials that are specially designed for long-lasting durability and exceptional performance. The disc's abrasive material is made from high-quality zirconia alumina, which is a type of synthetic abrasive that is well-known for its superior performance in grinding and sanding applications. It offers excellent cutting power and is highly efficient at removing material quickly, making it ideal for various industrial applications.
How To Use Flap Disc Safely And Efficiently
Working Angle And Pressure
Operate the flap disc at an angle between 2°and 15°for type 27 or 15° and 25° for type 29.
Do not exceed those angles to ensure an efficient and safe application.
Apply the optimal pressure by letting the rotational speed of the flap disc do the work.
Applying excessive pressure that bends the outer edge of the flap disc leads to premature wear and decreased tool life.
Proper Operational Speed
For optimal performance, move the flap disc along the surface slowly and steadily allowing the rotation of the flap disc to do the work.
Do not move the flap disc too quickly, nor aggressively back and forth. This will decrease its performance and provide a rougher surface finish.
Faster does not equal better when it comes to flap discs.
Proper Trimming
Incorrect trimming can damage the flap disc. Some rules of thumb are:
Never trim at a 90°angle since this increases the risk of kickback.
Trim on secure sharp edges only.
Gently guide the backing of the flap disc towards the cutting edge.
Slightly angle your grinder between 15 and 25 degrees and, once the adhesive begins to appear, lower your angle, and stop trimming.
Unveil ¼” (6 mm) of new overhang at a time.
DO NOT trim the backing more than the recommended number of times as it will damage the structural integrity of the backing.
All flap discs are fragile. They should be handled with care. As the background is a hard disk, this will make flap disc used with an extra life.
Flap discs should be stored on a flat, rigid surface, avoiding damp and frost or wide variation in temperature. The foam spacer inside will keep dry and flexible in this way, and more suited for producing a smooth finish to curved surfaces.
Use the oldest discs (on “first-in, first-out” basis). Old flap disc has a shorter life than new, it is a good way to take advantage of using them this way.
