Features Have to Consider to Sander for Metal

Choosing the right sanding machine for metal would be tough if you don’t know which one is suitable to complete your project. Here you’ll find some important features that make a sander the best one.

The Material You Sand

As you’re working with metal, you know what type of metal you’ve to deal with every day. Different types of metal need different types of sander. Such as stainless steel, high carbon steel, cast iron and aluminum require different types of belt sander or orbital sander pads.

Some prefer a belt sander to work on carpentry, glassmaking, woodworking along with metalwork. In this case, you need to change the orbital pad before switching the job.

Choose the Type of Sander

For metal work, you choose from belt sander and orbital sander depending on the type of finishing you want on your project.

Belt sanders can give you nice polishing & finishing on edges & corners. You can have control over shaping the edges with a belt sander.

Orbital sanders help you to get smooth finishing on round corners and edges like metal piping or some automotive or aircraft parts which need the finest tool for a perfect fit.

Consider the Sandpaper

Usually most metal workers prefer 50 grit sandpaper for metal working. But this may vary depending on the type of metal you are working with.

Like, steel tends to be the hardest metal which generates heat quickly, that means you need to cool it down frequently while working.

When you are sanding aluminum, silicon oxide is the best alternative to working with. But you need to prepare water or other cooling agents to reduce the heat.

Many metalworkers prefer cubic zirconia/ industrial diamond sandpaper & orbit pads as they generate minimum heat and require almost no lubrication. And as it is a hard type of sandpaper, it tends to last for a long time.

Power Supply

Before buying the metal sander you must think about your power supply. Because high-end sanders require higher voltage and current than any household electrical system. So check the required voltage of the sander before buying.

Horse Power

Another most important feature you should consider for buying a sander is HorsePower aka HP. If you’re going to use it for DIY purposes or small scale home or professional purposes, a sander with ⅓ – ½ HP will be great. But if you’re a full-time professional, you should go for a more powerful sander.

Available Space

You also need to consider available space at your workstation for the sander. That means you need to make sure that you’ve enough space in your workshop to place a bigger, free-standing model of the sander.

Size of the Sanding Platform

If you choose Belt sander for your project, check the length and width of the sanding platform before buying. Belt sander with a wide and long belt helps you to finish your job quickly.

Dust Collection System

Any type of sanding produces enough dust & debris to mess up your workspace which may affect your breathing. So check if the sander you’re going to buy has a good dust collection system. But whatever the method is, it is always better to wear safety glass and a dust mask while using this type of tool.

Some Perfect Options of Sander for Metal

  •  Power Source Air Powered;
  • Sander Revolution 14000 RPM;
  • Belt size 3/8×13-inch; 
  • Weight: 2.18 pounds;

Most of the users have claimed the versatility to be the best feature of this sander, but for me, its limitless sanding is my favorite. It is a two-in-one sander that can be bolted down on a table to use as a bench sander or flip over and glide through the surface you want to smooth out. There are two handles with a rubber grip on both sides of the sander to make sanding stress free.

Its rotational speed is variable; you can choose within 13 settings depending on the material. The advertisement claims this sander is a jack of all trades; from wood to tile, anything can be polished. However, its slow rotational speed seemed less suitable for soft materials like natural or artificial wood. It is a great weapon to polish harder substances like metal or tile.

To ensure your workshop remains lean, there are two dust ports attached to it. Just lock the machine, do your sanding and empty the dust collector. Sandin has never been easier like this. The price is so low on this machine, that we had to double-check if there is a digit missing!

Things We Liked

  • Variable speed suitable for different materials
  • Made of high-quality stainless steel;
  • It has strong rust resistance;
  • Corrosion resistance, and stress resistance.

Things We Didn’t Like

  • Nothing found.

An air belt sander is the only choice to remove welds from hard-to-reach areas of metal pieces like automobiles and so on. The reason we placed this ASTRO sander on our list is, it is cheap, comes with 3 belts of different grits, and is super easy to use. The most fascinating matter is, with the speed control, placed on the trigger this tiny machine can become a beast.

Usually, sanders meant for metals are made lightweight. But air belt sanders are the lightest. Due to just 1 kg of weight, this sander is going to be your best friend in terms of portability. It will let you expand your territory of working with it, as you can carry this wherever you go. So, mechanics who work on various projects will find removing welding is a breeze with this sander.

There are other models available in the air belt category. But most of those cost a lot even if those come with similar features. With a short warranty option, Astro sander can beat the deal and save you from overspending on other options.

Things We Liked

  • Suitable to polish tight spaces;
  • Ultra-lightweight;
  • Affordable;

ZFE Burnishing/Polisher/Sander Set With Burnishing Wheel

  • Application: polish, tarnish and burnish steel and non-ferrous metal;
  • Motor: ½ hp;
  • Rotation: 600 to 3,000 RPM;
  • Wheels: 80# FLEECE (Nonwoven) wheel;
  • Weight: 12.35 pounds;

This one serves ‘various purposes’ of various materials’; others only claim their sander’s versatility on serving a lot of purposes, but a few are eligible to do so on various materials. These sander works wonder on cleaning rust, scratch or just plain dullness on the metals.  

It is not super light because the way it touches the floor requires extra strength. The strength comes from the weight of the machine. Besides, you can choose to use the energy settings to use this sander on materials other than metals. The simplistic construction of this machine makes it convenient to use on large metal pieces very conveniently.

This sander is pricier than its other competitions. However, the performance, additional attachments, and safety measures incorporated by the manufacturer totally deserve it.

Things We Liked

  • Versatile usage;
  • Comes with speed settings;
  • Easy to operate. 

Things We Didn’t Like

  • Pricey.

Baileigh Combination Belt and Disk Grinder (Model No  DBG-62)

Baileigh Combination Belt and Disk Grinder

  • Application: various applications on different materials;
  • Motor: ½ hp;
  • Speed: 4400 FPM;
  • Rotation: 2800 Rpm;
  • Disk: 6 inches;
  • Belt: 2×40 inches;
  • Weight: 75 pounds.

Before heading towards review, I would like to mention that this sander is the most expensive one of this write-up. Despite being a bench-top type sander, we realized that this unit can be great for sending tiny metal pieces of critical shapes. Whilst other sanders are suitable for large surface areas, this one is more appropriate for DIY and crafting.

It comes with a powerful motor that produces sufficient speed to the attached belt and disk. The belt is long, with a detent table and the sanding disk is somewhat small. This machine runs silently. The only bothering thing is its weight. You can’t move it very often. If you are here for a portable unit, this one is not meant for you.

Things We Liked

  • Bench-top style;
  • Smooth and convenient operation;
  • Suitable for small pieces. 

Things We Didn’t Like

  • Expensive;
  • Very heavy;

XtremepowerUS Belt / Disc Sanding Machine Work Station (Model No 46000)

  • Motor: ½ hp;
  • Speed: 13.5 m/second;
  • Rotation:3,600 Rpm;
  • Disk: 5 inches;
  • Belt: 1×30 inches;
  • Weight: 18 pounds.

This machine has a different speed on its belt and disk. The disk is suitable for woodworks and the belt is more convenient for polishing metals. This bench-top style machine is super light which increases its portability. Hence, I recommend this one for newbies so that they can test their limits with this before switching on to a professional one.

This machine may not be long-lasting, considering the reviews we have got from its long term users. But for occasional usage, it is absolutely alright. There is no dust bag included with the package, so make sure you own a shop vac before using it properly.

Things We Liked

  • Portable; 
  • Suitable for metal and wood.

Things We Didn’t Like

  • No bag attached to the dust port;
  • Comes with a belt and disk of large grits. 

Conclusion

So, this is all I had to share with you about metal sander. Hope you’ve got the idea about selecting a sander for your metal work.

But if you ask for my opinion, I’d go for TACKLIFE Variable Speed Belt Sander, as it has a powerful motor, moderately wide belt, perfect dust port and moreover, it can be used on metal, glass, tile and any other material.

Let me know which one you’ll get for you and why!
