Quick Change Sanding Discs
Quick Change Discs, also referred to as Quick Lock Discs, can be used for a host of purposes. Quick change discs provide the ideal shape and size for smaller work surfaces and tighter shape restrictions. When compared to PSA discs, these attachments can withstand the high temperatures generated during the grinding process without flying off. Quick Lock Discs can be used for both grinding and finishing. This category encompasses the following capabilities:
- Weld removal
- Removing weld splatter
- Deburring
- Edge breaking
- Surface prep
- Finishing
Quick Change Discs are available with 3 different locking styles:
- Type S – Interchangeable with Norton Speed-Lok TS, Standard Abrasives or 3M TS, Merit Powerlock Type 2 (can be plastic or metal)
- Type R – Interchangeable with Norton Speed-Lok TR, Standard Abrasives or 3M TR, Merit Powerlock Type 3
- Type P – Interchangeable with Merit Type 1
Grain Types
The most common grains for a quick change disc are aluminum oxide, zirconia alumina, and ceramic. While all of these grain types can technically be used on any metal type, there are specific qualities inherent to each that make them better suited for specific types of applications.
Aluminum Oxide
Aluminum oxide (AO) is a general-purpose grain that should be used on mild steel, aluminum, and non-ferrous materials. Aluminum Oxide is the oldest, most tried and true grain out of the bunch. Its versatility allows it to work on all metals, however, it is best used for mild steel as harder metals can cause it to wear down quickly. We offer two types:
- AO Premium is our classic disc option, reinforced with a BLUE cloth backing meant to improve general stability and durability.
- AO Extreme offers a different RED backing meant to increase rigidity and durability to an even greater degree. It also reduces edge wear and snagging.
Zirconia
Zirconia provides an upgrade in performance over aluminum oxide on mild or stainless steel. Zirconia offers re-sharpening capabilities as grains wear down, a notable improvement from Aluminum Oxide. This is our best middle-of-the-road option, providing improved capabilities compared to aluminum oxide but still offering a cost-effective price point.
Ceramic
Ceramic is our maximum performance material, operating best on mild or stainless steel, titanium and inconel. Ceramic can be especially useful in aerospace applications as it holds up to the hardness of the metal and does not wear down as quickly as other grain types might. Ceramic takes the re-sharpening function of Zirconia and improves it to an even greater degree, offering not only increased resilience to the hardness of metals but also high heat resistance.
Backing Pads
Our PREMIUM Backing Pads provide much-needed support for all grain types in order to improve performance. These pads provide ventilation to keep the abrasive cool as well as offer support to extend the life of the disc. Our TRADITIONAL RUBBER Backing Pads offer more flexibility when needed.

Finishing Quick Change Sanding Discs
Finishing discs are made of soft “hand pad” type material. They can remove slight imperfections, light oxidation, and other minor defects. NOT intended for deburring. Designed for light removal of coatings, oxidation, or rust without affecting the base product. The aluminum oxide grain and resin bond combination produce a smooth cut rate and smear-free uniform finish. -
Hi-Strength Quick Change Sanding Discs
High-Strength fibers combined with high grain content make these durable discs ideal for light deburring or final finishing work. Strong fibers resist snagging or tearing. Great for final finish on aerospace parts or edge deburring on extrusions. Easily conforms to irregular surfaces. -
Quick-Lock Discs
Quick Change discs are available with 3 different locking styles: Type S – interchangeable with Norton Speed-Lok TS, Standard Abrasives or 3M TS, Merit Powerlock Type 2 (can be plastic or metal) Type R – interchangeable with Norton Speed-Lok TR, Standard Abrasives or 3M TR, Merit Powerlock Type 3 Type P – interchangeable with Merit Type 1 -
Surface Conditioning Quick Change Sanding Discs
Premium: PREMIUM Surface Conditioning Discs are made from stiff scrim backed material designed exclusively for disc use, and have excellent grain retention and are smear resistant. They are great for deburring, blending machine tool marks, general surface cleaning, gasket removal and heavy rust and oxidation removal. GP: GENERAL PURPOSE Surface Conditioning Discs are made from stiff scrim backed material designed exclusively for disc use. Best choice for economical deburring. They are great for deburring, blending machine tool marks, general surface cleaning, gasket removal and heavy rust and oxidation removal. Max-Finish: MAX-FINISH Surface Conditioning Discs feature a softer scrim backing and will leave a smooth finish without leaving any "stray" scratches. They are less aggressive than our Premium discs, great when surface finish is the primary concern. HD: HEAVY DUTY Surface Conditioning Discs are a combination of AO and Ceramic grains, with additional resin for added strength and durability. These discs are very stiff and aggressive, which make them the best choice for heavy deburring, weld grinding, and splatter removal. -
Surface Prep Quick Change Sanding Discs
These soft unitized discs are thicker and more cushioned than traditional unitized discs. They will remove light scratches and imperfections without altering the base material. -
Unitized Quick Change Sanding Discs
XL Unitized Discs are a great choice for light deburring, and blending, as they provide a consistent, uniform finish. These discs are smear resistant and have a long life. 6AM - Capable of heavier deburring and surface finishing. 2SF & 2AM - light deburring and removal of imperfections without altering base material. GFP - Green Final Polish wheels will leave a bright "mirror like" final finish on a variety of metals. They will not alter part geometry and do not require compound! CP Unitized Discs – Better choice for light weld bead and weld splatter removal and heavy deburring and finishing applications. 3AM, 5AM, 7AM – High performance engineered grain. Harder and more durable than XL wheels. Aggressive fast stock removal with nice finish.
