• Sisal wheels are strong. You use them to cut and polish hard metals like stainless steel.

• Satin or matte buffs use fake fibers. These give metal a soft, brushed look.

• Aluminum oxide flap wheels and silicon carbide wheels help grind and smooth metal.

• Nylon and wire wheels clean and remove rough edges.

You can see how each wheel fits in your kit in the table below:

Choosing the Right Size

You want your machine to work well. The size of your buffing wheels is important. For stainless steel, 8-inch airway buffing wheels are a good pick. They keep cool and help you polish faster. Use different compounds with each wheel for better results. Start with black emery compound for cutting. Then use brown Tripoli for color buffing. Finish with green rouge for the final shine. Always match the wheel size to your machine and the metal you polish.

Maintenance Tips

If you want your kit to last, take care of your buffing wheels. Clean them often to get rid of old compounds and dirt. Check for damage before you start. Store wheels in a dry place with covers. Balance your wheels to stop shaking. Use the right compounds so wheels last longer. Dress the wheels to show fresh abrasive. Lubricate cotton wheels with wax or grease if needed. Handle wheels gently and follow safety steps when you change them. Good care helps your machine work better and keeps you safe.

Tip: Always check your buffing wheels before you polish. This easy step can stop accidents and help you get a better finish.

Polishing Compounds for Metal Polishing

Common Types

You need the right polishing compound in your polishing kit to get a smooth, shiny finish. Each compound works best for a certain stage of metal polishing. Tripoli is a cutting compound. You use it first to remove scratches and dull marks from aluminum, brass, or copper. After Tripoli, you switch to rouge compounds for the final shine. Jeweler’s rouge, like green or blue, gives you a mirror finish on aluminum and other non-ferrous metals. Brown Tripoli works well for softer metals, while white rouge is great for harder metals like chrome.

Here’s a quick guide to help you pick the best compound for your polishing kit:

If you want a high-gloss finish on aluminum, use a soft cloth buffing wheel with a medium grease compound. Store unused compounds in airtight containers to keep them fresh.

Application Tips

You want your metal polishing kit to work fast and clean. Start by sanding your metal with high grit sandpaper. Use 1200, 1500, then 2000 grit. Next, apply brown Tripoli compound with a buffing wheel. Buff the surface gently. Switch to a rouge compound for the final polish. Use a clean wheel for each compound to avoid mixing. For a quick shine, try Quick Sheen All Metal Polish. Wipe it on with a soft cloth, let it dry, then buff it off. You can use a buffing wheel for tough spots. This method helps you avoid black grease marks and keeps your metal clean.

Tip: Always use a small amount of polishing compound. Too much can leave streaks and make a mess.

Safety Notes

You need to stay safe when you use chemical polishing compounds. Work in a space with good airflow. Wear gloves to protect your skin. Always follow the instructions on the compound container. Use safety glasses and a mask if you see dust. Never breathe in the dust from polishing. Keep your polishing kit away from kids and pets.

Note: Store your polishing compounds in airtight containers if you do not use them for a month. This keeps them fresh and ready for your next metal polishing job.

Sandpaper Grades

Surface Preparation

You want your metal polishing kit to deliver a smooth, shiny finish. The first step is always surface preparation. You start by removing dents and scratches with coarse sandpaper. This gets rid of big flaws and sets up your metal for polishing. Move to medium grit sandpaper next. This step helps you even out the surface and makes it ready for fine polishing. Clean the metal between each sanding stage. Dust and old grit can mess up your results. If you see any leftover marks, repeat the sanding process until the metal looks smooth. When you finish, wipe the surface clean and get ready for the next step in your polishing kit.

Tip: Careful surface prep means fewer scratches and a better final shine when you polish.

Grit Selection

Picking the right sandpaper grit makes a huge difference in metal polishing. You need to match the grit to your metal and your goal. Coarse grits like 40-60 work best for stripping paint or heavy sanding. Medium grits, usually P100 to P220, are perfect for prepping metal before polishing. Fine grits, starting at P240 and going up to P400 or higher, help you get that smooth, shiny finish. Softer metals like aluminum need finer grits so you don’t scratch them. Harder metals such as steel or titanium can handle coarser grits and tougher abrasives. Always start with a coarse grit for big jobs, then move to medium and fine grits for polishing. Using the wrong grit can damage your metal and shorten the life of your polishing kit.

Here’s a quick table to help you choose:

Usage Tips

You want your polishing kit to work as hard as you do. Always start with the lowest grit you need and move up step by step. Don’t skip grit stages. If you jump from coarse to fine, you might leave deep scratches that are tough to remove. Use water as a lubricant when sanding. This keeps the metal cool, reduces dust, and stops the sandpaper from clogging. For aluminum, stick with finer grits and wet sanding to avoid scratches. For steel, begin with coarser grits and keep the surface cool. Sand in the direction of the grain for stainless steel. Use gentle pressure and keep the sandpaper moving. If you press too hard, you can warp the metal or leave uneven marks. Clean the surface after each sanding step. This helps your metal polishing kit give you the best results.

• Start with 600-grit sandpaper for polishing, then move to 1000 or 2500 grit for a mirror finish.

• Use aluminum oxide sandpaper for hard metals.

• Use silicon carbide sandpaper for softer metals.

• Always use water or lubricant to prevent overheating.

Note: Careful sanding and cleaning between steps will help your polishing kit last longer and give you a flawless finish every time.

Safety Flanges

Preventing Wheel Slippage

You want your metal polishing machine to be safe. Safety flanges help keep it that way. These parts hold buffing wheels tight while you work. If you polish at high speeds, wheels might slip or fall off. Safety flanges stop this from happening. They give you extra protection. You can focus on polishing and not worry about accidents.

• They hold buffing wheels in place when you polish.

• They stop wheels from slipping or flying off fast.

• They fit many buffing wheel sizes for different jobs.

• You can put them on and take them off easily.

Tip: Always look at your safety flanges before you polish. Checking them quickly can stop dangerous wheel slips.

Installation Tips

You want your safety flanges to work every time. Putting them on the right way is important. If you mess up, you could get leaks or break your machine. Here are some things to remember:

• Line up the flange the right way. Bad alignment can cause leaks.

• Tighten bolts evenly. If one side is tighter, the gasket can break.

• Use a star or cross pattern to tighten bolts. This spreads pressure out.

• Pick the right gasket for heat and pressure. The wrong one can leak.

• Do not scratch or dent the flange when you install it.

• Use lubrication to make fitting easier and stop leaks.

• Check flanges for damage or wear. Replace bad ones before you polish.

• Use tools that stop rust and keep flanges strong.

Note: Lining up flanges and tightening bolts right helps you make a strong seal. Good installation keeps you safe and helps you polish better.

Extender Kits

Improving Accessibility

You know how tough it can be to reach small corners or tight spaces when polishing metal. Extender kits make this job much easier. These kits give you extra reach, so you can polish spots that your machine cannot touch on its own. For example, Adam's SK Pro Micro Rotary Attachment Accessories come with an extension shaft and small polishing pads. You can use pads as tiny as half an inch. The kit even has a five-foot cable. This lets you move your polisher into tricky areas like inside car trim or around gauge clusters. You do not have to struggle or twist your hands into odd angles. The Stanley 3-piece Extension Bar Set also helps. It gives you three different lengths—3, 6, and 10 inches. You can pick the right size for each job. These tools let you polish every part of your project, even the hardest-to-reach places.

Tip: Use extender kits when you need to polish inside holes, around bolts, or in deep grooves. You will get a smoother finish without missing any spots.

Safety Benefits

Extender kits do more than just help you reach. They also keep you safe while polishing. When you use an extender, you can keep your hands farther from spinning wheels and hot surfaces. This lowers your risk of cuts or burns. You do not have to force your machine into tight spaces, so you avoid slips and accidents. The extra length gives you better control. You can polish with steady hands and less strain on your wrists. Some kits even have grips or covers to stop your hands from slipping. You stay comfortable and safe, even during long polishing sessions.

• Less hand strain

• Lower risk of injury

• Better control for detailed polishing

Note: Always check that your extender kit fits your machine before you start polishing. A good fit means safer, smoother work.

Taper Adaptors

Angle Grinder Conversion

You might want to turn your angle grinder into a metal polishing tool. Taper adaptors make this possible. These small parts connect your angle grinder spindle to buffing wheels. You can use your angle grinder for polishing jobs without buying a new machine.

Here’s what makes taper adaptors so useful:

• They let you attach buffing wheels to your angle grinder.

• You can use different polishing accessories with your grinder.

• They fit many common spindle sizes, like M14 x 85mm, M14 x 104mm, and 5/8"-11UNC x 114mm.

• You get more use out of your angle grinder.

When you use a taper adaptor, always check the speed. Keep your angle grinder under 3000 RPM during polishing. This helps you stay safe and get a better finish. If you go too fast, you might damage your buffing wheel or the metal.

Tip: Always wear safety glasses and gloves when you use your angle grinder for polishing. Safety comes first!

Compatibility Notes

Not all taper adaptors fit every angle grinder. Before you buy one, check your grinder’s spindle size. Most adaptors list the sizes they fit. If you pick the wrong size, your buffing wheel might not stay on tight. That can be dangerous.

You should also check the type of buffing wheel you want to use. Some wheels need a certain adaptor shape or length. Make sure the adaptor matches both your grinder and your wheel. If you are not sure, ask the seller or check your machine’s manual.

• Match the adaptor to your grinder’s spindle thread.

• Make sure the adaptor fits your buffing wheel.

• Test the fit before you start polishing.

Note: A good fit means safer, smoother polishing and less trouble while you work.
