Comprehensive Lineup of Roll-On & Lock-On Abrasive Discs

At The Avenjers Industrial Supply, we carry a broad selection of 2-inch and 3-inch quick change disc attachments designed for various metalworking stages and die grinder holder pads:

• Type R (Roll-On / Male Threaded) Discs: Industry-standard plastic threaded male button discs designed to twist directly onto Type R rubber backing pads.
• Type S (Lock-On / Metal Threaded) Discs: Heavy-duty metal threaded button discs engineered for high-torque grinding and secure pad retention.
• Ceramic & Zirconia Quick Change Discs: Self-sharpening high-performance mineral discs built for rapid stock removal, heavy deburring, and stainless steel finishing.
• Non-Woven Conditioning Quick Change Discs: Surface conditioning discs designed to strip rust, clear gasket residue, and produce uniform satin finishes.

Technical Advantages & Industrial Applications

Choosing commercial-grade quick change abrasive discs ensures fast workpiece transitions and maximum cutting efficiency across trades:

• Tool-Free Fast Swapping: Twist-on and twist-off attachment design allows rapid transitions from coarse grinding to fine surface conditioning in seconds.
• Tight Angle Access: Compact 2" and 3" disc diameters reach inside narrow pipe channels, recessed castings, and auto body repair seams.
• Gasket Removal & Flange Cleaning: Surface conditioning discs clean engine block flanges and pipe fittings without gouging metal surfaces.
• High-RPM Stability: Molded center hubs prevent disc slip and off-center wobbling at high rotational speeds.

Frequently Asked Questions (FAQs)

What is the difference between Type R and Type S quick change discs?

Type R (Roll-On) features a plastic threaded male screw attachment compatible with Roll-On backing pads. Type S (Lock-On) features a metal threaded snap button attachment compatible with Lock-On backing holders. Always match the disc hub attachment to your holder pad type.

What power tools are used with quick change discs?

Quick change discs are designed for pneumatic or electric die grinders, right-angle air grinders, and rotary drills fitted with 1/4-inch shank rubber holder pads.

Can I use non-woven surface conditioning discs on aluminum?

Yes. Non-woven quick change conditioning discs excel at cleaning aluminum castings and sheet metal without loading or gouging soft alloys.

What grit size progression should I use for spot weld removal?

Begin with a coarse ceramic disc (36 or 50 grit) to rapidly level the weld, transition to medium zirconia (80 grit) for blending, and finish with a medium non-woven conditioning disc.

How do I know when a quick change disc needs replacement?

Replace the disc when stock removal rates drop significantly, when the abrasive backing shows fraying, or when the threaded center hub shows wear.

What maximum operating speeds are safe for 2-inch and 3-inch discs?

Standard 2-inch quick change discs are generally rated up to 30,000 RPM, while 3-inch discs are rated up to 20,000 RPM. Always verify speed ratings printed on holder pads and disc packaging.
