A flap wheel and or flap discs comprise hard discs, which provide surface finishing of metals. Unlike the simple flat discs that consist of grit, impregnated and adhesive (cement) on two sides spelt flat and a coated sheet, featuring a hub in the middle of a flap wheel, it is as different as these parts of small overlapping flaps that are sticking to the central hub. Looking to buy flap discs? Let us go through the basics.

Types of Flap Discs

The  flap disc types include: 

Flat Discs

Flap discs, also called type 27 flap discs, grind more ideally on a shallow plane when the angle is between 0° and 15°. They are perfect for smooth finishing and blending for flat surfaces.

Conical Discs

A conical disc is also known as a cup-shaped disc rather than a straight disc. They can normally grind at 15-35 degrees grind levels. These tools provide the operator with optimal stock removal capabilities and reduce the gap on the surface of flat areas.

Trimmable Discs

Flap discs can be trimmed apart from the other types because of the presence of a composite backing that can be trimmed to the desired and preferred overhang. However, when they are used as supposed to be, they offer flexibility together with the needed versatility for the areas that are hard to reach, for instance, fillet welds and irregular shapes. 

In addition, since the backing materials never come into contact with any workpiece surfaces, there is no fear of marking.

Aluminium-backed Discs

Flap discs with aluminium backs contain a sturdy, permanent aluminium backing. This ensures reliability in severe conditions of stress and heavy-duty applications.

Mini Discs

The mini flap discs have a diameter of 2-3 inches only. Compact frames allow them to gain access to tight spaces and grinding in hard-to-reach areas. Mini discs, 2 inches wide on average, can do better than many blending discs. Some of them are as large as 4 inches. These discs contain a composite backing that provides standard support for a range of applications.

Angled Discs

Angled discs have curved flaps having the shape of a curve wrapped around the back plate of the grinding discs, providing more intense and precise grinding. The curved flaps give these discs the contouring capabilities necessary for fillet welds and allow for access to hard-to-reach areas for T-joint grinding. They offer the same robust grinding performance on flat surfaces.

Factors to Consider Before Buying Flap Discs

The factors to consider before buying flap discs according to flap discs specifications include: 

Disc Diameter and Grit Size

The diameter of the flap disc would determine its coverage and compatibility. Larger diameters cover more surface area, fit for areas with considerable units, while smaller diameters provide a solution for precision in a small area. The ability to obtain the desirable degree of coarseness or fineness of abrasive particles is referred to as grit size. Coarser grits speed up the process of scraping but possibly leave coarse finishing; finer grits only scrape more slowly but, in turn, leave smoother finishes.

Material Compatibility

Being aware of the material you'll be working with, whether it is metal, wood, or others, is the basic requirement. This kind of flap disc is for a particular material, but these special flap discs are for optimal performance and safety. Having the wrong type of flap could lead to ineffective grinding and a short life span of the discs and bring about safety problems.

Abrasive Material and Backing Type

The flap discs may be manufactured from different abrasive materials such as alumina oxide, zirconia alumina, or ceramic alumina, silicon carbide, etc. Those coarse materials, according to their different hardness levels, durability, and the fact that they are specifically for certain applications, are alike. Backings may be made of fibreglass, plastic or metal, ensuring different amounts of flexibility, durability, and continuous workability.

Flap Configuration and Number of Flaps

Flap configuration relates to the positioning of the abrasive disks where the flaps are placed. Different configurations provide different levels of aggressiveness, surface finishes, and heat dissipation. Furthermore, the number of flaps to the disc affects the rotation speed and longevity. The increased number of flaps usually means better quality finishes and a longer service period, but it could reduce the aggressiveness in returns.

FAQs About Flap Discs

Q1. How do I choose the right grit size for my flap disc?

The grit size you choose depends on the material you're working with and the finish you desire. Coarser grits (e.g., 40-80) are suitable for heavy material removal, while finer grits (e.g., 120-240) are ideal for achieving smoother finishes.

Q2. How do I ensure the safety of using flap discs?

To ensure safety, always wear appropriate personal protective equipment (PPE), such as safety glasses, gloves, and a face mask to protect against dust and debris. Follow the manufacturer's instructions for the specific flap disc you're using, including the recommended operating speed and maximum RPM (revolutions per minute) of your tool.

Q3. What are the advantages of flap discs over other abrasives? 

Flap discs offer several advantages over other abrasives, including versatility, efficiency, and cost-effectiveness. They can grind, blend, and finish in a single step, reducing the need for multiple tools. Flap discs also provide smoother finishes with less gouging compared to grinding wheels.
