Burr King Grinder Models and Compatible Belt Sizes

We supply sanding belts to match all major Burr King belt grinder models. Each machine is built for different kinds of work, from light shaping to heavier grinding, and belt size plays a key role in how each one performs. 

• BBA20:The BBA20 is one of Burr King’s most powerful machines. It’s used in both industrial and small-shop settings where long belt life and consistent tracking are important. This model runs 2" x 72" belts, which are ideal for grinding knives, shaping metal, or cleaning up rough edges.
• Model 482:The Model 482 is a compact three-wheel grinder commonly used for finishing and shaping smaller parts. Its 2" x 48" belt size offers a balance between control and surface contact. Many shops use it for deburring, edge smoothing, and light fabrication work.
• Model 562:The 562 is a narrow-belt grinder that excels in tight spots or detailed grinding. The 1" x 42" belt gives you access to smaller surface areas without sacrificing performance. This model works well for sharpening tools, cleaning welds, and refining small parts.
• Model 720:The 720 is a probe-style grinder with extra reach. It's popular for contour grinding, internal shaping, and tasks that need a long belt contact area. You can use either 1" or 2" wide belts, depending on how much surface contact you need.
• Model 760:The Model 760 is a three-wheel machine used for heavy sanding or forming work. The 60" belt length helps reduce heat and improves lifespan during extended use. With two width options, users can match the belt to the type of job they’re doing.
• Model 960-250 and 960-251:These two-wheel grinders are often found in production environments where high throughput is needed. The wider 2.5" belt covers more surface area, which helps speed up flat grinding and cleanup. The 960-251 includes wet-grinding capability, which helps reduce dust and heat on heat-sensitive materials.
• Model 960-272:The 960-272, one of the most widely used Burr King models, fits the standard 2" x 72" belt size. It works for everything from stock removal to polishing. Shops value this machine for its versatility and dependable performance under daily use.
• Model 960-400 and 960-401:These models handle wide belts with full face contact for surfacing and shaping. At 4 inches wide, they’re recommended for preparing larger parts and cleaning welds across broader surfaces. Like the others, the wet option helps extend belt life and keeps temperatures down during longer grinds.
• Model 979:This machine runs an extra-long belt and provides a large working area for shaping and surface prep. The 3" width offers more coverage while still allowing for detailed control. It’s often used on stainless steel, aluminum, and other materials that benefit from a smoother touch.
• Model X400:The X400 is aimed at shops that want industrial performance without taking up much space. Its 2" x 48" belts are easy to change, and the machine works well for sharpening, shaping, and sanding. It’s a reliable option for fabricators, machinists, and anyone who works with metal or wood.

No matter which Burr King model you own, we manufacture belts that fit the machine and match the demands of your work. Each size is available in multiple abrasive materials and grit levels to give you the results you're looking for. If you're unsure which belt is right for your grinder, our team is here to help you sort through the options.

Abrasive Grains for Every Application

Our sanding belts are made with a range of abrasive grains to meet the demands of metalworkers, fabricators, and machinists. 

EdgeCore Premium Ceramic

• Best For:Tool steels, hardened alloys, stainless steel, titanium
• Why Choose It:This innovative ceramic blend has a self-sharpening grain that holds up under heat and pressure. It’s known for a fast cut rate, clean finishes, and belt life that outlasts most other abrasives on the market. EdgeCore is ideal for aggressive grinding or shaping work where time, efficiency, and consistency matter.

Zirconia

• Best For: Carbon steel, mild steel, stainless steel
• Why Choose It:Zirconia is built for pressure. It lasts longer than aluminum oxide when grinding harder metals and is often used for rough stock removal or edge shaping. This abrasive is a good middle ground between cost and performance, especially in general shop use or for frequent belt changes.

Aluminum Oxide (AO)

• Best For: General metalwork, wood, aluminum, brass
• Why Choose It: Aluminum oxide is the standard workhorse for day-to-day sanding. It’s cost-effective and adaptable, especially for lighter materials or tasks that don’t require aggressive grinding. Red Label offers aluminum oxide belts in several configurations, including flexible backings, scalloped edges for detail work, and compact grain options that improve surface uniformity.

Silicon Carbide

• Best For: Non-ferrous metals, composites, rubber, stone
• Why Choose It: Silicon carbide is a sharp, fast-cutting abrasive that resists loading and sheds heat well. It works best on materials that tend to gum up other belts or respond poorly to heat. If you’re working with rubber, plastic, fiberglass, or stone, these belts can help reduce discoloration and surface damage.

Grit Selection Guide

Your choice of grit directly affects how your project turns out. A belt that's too coarse can leave deep scratches, while one that's too fine can take longer to finish the job. Below is a general guide based on the kind of work you're doing and the results you're after.

Coarse Grits (36–80)

These grits are made for heavy removal and rough shaping. They work well for stripping mill scale, grinding off rust, or cutting through welds and hard edges. If you're working on raw steel, cleaning up castings, or forming the initial shape of a blade, coarse grits will save time and keep you moving. Ceramic and zirconia belts in this range handle the heat and pressure of this type of work without wearing out too fast.

Medium Grits (100–220)

Medium grits are useful for refining shapes and preparing surfaces for the next step. They're ideal for smoothing contours, flattening edges, or removing marks left behind by a coarse grit pass. This range is often used for general cleanup, whether you’re working with metal, wood, or composite parts. It’s a dependable middle step between aggressive grinding and fine finishing.

Fine Grits (320–2000+)

Fine grits bring the surface closer to finished. These belts are used to polish, edge-refine, or get parts ready for paint, etching, or coating. If your work needs a clean, level surface or if you’re preparing a visible finish, this is the range to use. Structured grain and compact grain belts perform especially well here, and J-weight aluminum oxide belts are often chosen for their controlled output.

If you're not sure which grit progression fits your setup, we're happy to help. We can recommend a belt sequence based on your machine, the material you're grinding, and the results you're aiming for. Let us know what you're working on, and we’ll point you in the right direction.

How to Get the Most Out of Your Belts

Burr King grinders are built for accuracy, and a good belt can maximize results. But even the best abrasive won't perform well if it's worn out, clogged, or handled incorrectly. To keep your belts cutting clean and lasting longer, follow a few simple habits:

• Always start by checking belt tension and tracking before you begin grinding. A loose or misaligned belt can slip, fray, or wear unevenly, which affects the finish and wastes material. Taking a few seconds to adjust the tracking dial and confirm a snug fit will prevent a lot of issues down the line.
• Apply only light to moderate pressure while grinding. A quality belt should cut through material on its own, without the need to push hard. Pressing too firmly creates unnecessary heat and wears the abrasive faster than needed, leading to shorter belt life and a rougher result.
• To avoid heat damage, use the right grit for the task and make consistent passes without lingering in one spot. Heat can damage both the belt and the workpiece, especially when grinding hardened steels. If you see discoloration or feel excessive warmth, it’s time to adjust your approach.
• Use a rubber belt cleaning stick regularly to remove metal particles and surface buildup. Belts that look glazed or clogged will stop cutting cleanly and can overheat during use. A quick cleaning between uses can refresh the abrasive surface and restore cutting power.
• Store your belts flat and in a dry location to prevent curling or adhesive failure. Humid environments or hanging belts vertically can cause them to lose shape or weaken at the splice. Keep them sealed or in a clean drawer when not in use.
• Don’t mix belts between different materials. Using the same belt on both aluminum and steel can create cross-contamination, leading to blemishes, corrosion, or weld failure. Dedicate certain belts to certain metals and label them clearly if needed.

These habits will keep your belts performing the way they should. With a little care, you’ll get more life out of every pack and better results from your grinder.
