What Are Cartridge Rolls?
Cartridge rolls are standard abrasives used for performing sanding and finishing applications inside high-speed grinders and other air tools. These products comprise a cotton cloth-backed abrasive strip rolled around a cylinder and employ a multilayer coiled construction. They are available in a wide range of shapes, sizes and operating speeds, typically starting at 20,000 revolutions per minute (RPM) and above.
Abrasive cartridge rolls consist of aluminum oxide, which enables them to deliver powerful and dynamic sanding applications. This material is ideal for controlled, abrasive cutting on all metal types, including stainless steel.
Why Buy Abrasive Cartridge Rolls?
Cartridge rolls have long served as trusted sanding and finishing solutions due to their many innovative features and comprehensive capabilities. When you order abrasive cartridge rolls online from National Abrasives, you’ll experience a wide range of advantages you can’t get with other standard abrasives.
Abrasive cartridge rolls are optimized to work with a wide range of ferrous alloys and high-tensile materials. They are particularly useful for working with metals, such as stainless steel, copper, brass and titanium, as well as wood.
Due to their vast range of sanding and finishing capabilities, a/o straight cartridge rolls are suitable for performing many industrial metal and woodworking applications, such as:
- Edge breaking.
- General polishing.
- Flash removal.
- Irregular concaves.
- Dead-end holes.
- Tool mark blending.
- Hole porting.
- Hand sanding.
One of the primary reasons so many workers and artisans rely on abrasive cartridge rolls is their extensive reach. These sanding tools allow users to access narrow, hard-to-reach areas that other abrasives cannot. That’s because they feature a small diameter that fits well into tight spaces like inside surfaces, corners and holes, so you can use them in even the most limited and unwieldy positions.
Cartridge rolls have a unique multilayer design comprising wrapped abrasive sheets with a cotton cloth backing. When in use, this coiled construction reveals sharp new abrasive layers as the old layers wear. This innovative design allows for sharper, more aggressive cutting while producing a consistent finish. Its multilayer structure also promotes greater sturdiness and durability.
Due to their wrapped sheet design, abrasive cartridge rolls also save users time normally spent replacing worn-out rolls. Instead, they can continue working uninterrupted as fresh layers appear, minimizing downtime.
Get the Most From Your Cartridge Rolls
You can maximize your cartridge rolls’ potential by following the right tips. Adhere to the following steps to get the most out of your abrasives:
- Choose the right roll: Straight cartridge rolls are designed for general-purpose sanding, while tapered rolls are better suited for accessing small, hard-to-reach spaces.
- Wear PPE: Equip yourself with any personal protective equipment (PPE) you require for your application, such as safety glasses, hearing protection and gloves.
- Select the proper tool: While many tools are suitable for handling cartridge rolls, some will be more useful than others, depending on your application. Consider all your options, such as straight die grinders, power drills and right-angle die grinders, to choose the one that best serves your needs. Using a shrouded tool can minimize dust production during cutting.
- Mount the cartridge roll: No matter what tool you choose, you must use a mandrel to mount your cartridge roll to it. Adhere the sealed end of the roll to the mandrel on the side closest to the tool. Make sure your mandrel has a higher RPM rating than your chosen instrument to ensure optimal control and safety.
- Secure your workpiece: Once you secure your workpiece, you’re ready to begin sanding.
Choose the Right Grit for Your Cartridge Rolls
Grits refer to the number, size and coarseness of the cutting particles on the surface of an abrasive. Abrasive cartridge roll grits can come in various sizes but typically range from 60 to 320 grits. The higher the grit, the higher the number of grains, leading to a smoother surface finish. Lower-numbered grits, on the other hand, are better suited for applications requiring a coarse surface. Where your desired grit falls depends on your intended process and application.
The different types of grits and their applications are as follows:
- 60 to 80 grits: Grits between 60 and 80 comprise a medium texture between coarse and fine. This size range is moderately aggressive, making it ideal for rounding tough edges and removing paint and wood from surfaces.
- 100 to 120 grits: Grits in the 100 to 120 range have a fine composition. These grits are suitable for sanding wood, removing water stains on wood, cleaning plaster and other general-purpose sanding applications.
- 150 grits: 150-grit abrasives leave behind fine sanding marks. They are too fine to strip paint layers or smooth nicks, making them useful for feathering surfaces that have already been sanded.
- 240 grits: Abrasives with 240 grits are smoother and stronger than lower-numbered grits. They can accomplish thick paint-stripping applications without leaving behind streaks, damage or corrosion.
- 320 grits: 320-grit abrasives are ultra-fine, helping users achieve a shiny, glass-like texture. This strong grit type is excellent for buffering, polishing and thick paint removal.
