How to Cut Aluminum: Proven Cutting Methods
Common cutting techniques for aluminum include power tool cutting.
These tools and their usage methods.
Saw Cutting Aluminum
Circular saws are the first choice in the aluminum cutting industry. To cut aluminum sheets cleanly, metal-cutting saw blades are usually selected. Non-ferrous metal cutting blades are also widely used, including woodworking blades with carbide tips.
Circular saw blades are ideal for cutting aluminum sheets to size, as well as easily cutting aluminum pipes and profiles.
Cutting Aluminum with a Jigsaw
A jigsaw fitted with heavy-duty metal cutting blades can cut aluminum sheets cleanly. These aluminum cutting blades are specially designed for this purpose.
Variable cutting speed is also applied when cutting aluminum. Adjust the speed according to cutting requirements to cut aluminum tubes or sheets down to the required size.
Cutting Aluminum with a Circular Saw
Cutting aluminum with a circular saw is not an easy task. The best cutting results with a circular saw are achieved by using aluminum-cutting blades with carbide tips. It is important to secure and position the material at the corners with clamps. Cutting aluminum with a circular saw requires practice to handle complex cutting projects.
Cutting Aluminum with a Miter Saw
To get the best results when cutting aluminum, it is crucial to choose the right saw blade for the miter saw. For non-ferrous metals, triple-ground blades are the best option. This tooth profile delivers excellent performance on aluminum and also works well on plastics.
Miter saw cutting technology is suitable for both aluminum and steel. It produces far more chips than cutting ordinary wood materials. This cutting method is ideal for small aluminum projects.
Cutting Aluminum with an Angle Grinder
An angle grinder is one of the best tools for cutting aluminum. Compared with other methods such as sawing and drilling, it is the simplest aluminum cutting technique. Operators need experience to use an angle grinder with accuracy and precision. Once you become proficient, it is also the fastest cutting method.
Proper contact between the aluminum cutting disc and the metal workpiece enables precise cutting. The selection of aluminum cutting discs depends on the thickness of the metal. Diamond discs are recommended for thin aluminum sheets, while grinding discs are suitable for thicker sections.
It is also critical to ensure the disc is compatible with the angle grinder’s speed and size, which can reduce the risk of damage and material waste.
Waterjet Cutting of Aluminum Sheets
If you want to achieve high-quality results when cutting aluminum, the waterjet method is the best choice. It is equipped with a cutting head that discharges water at high pressure. The waterjet head is aimed at the metal being cut, and can cut through the full thickness of the material.
Abrasive waterjets are commonly used for aluminum cutting. Adding abrasive materials into the water jet allows aluminum to be cut quickly and easily. It outperforms laser cutting methods.
This advantageous cutting method causes no thermal deformation and produces no heat-affected zone during the cutting process. It can cut complex designs and deliver high-quality finished work.
Scoring Cutting Technology
Thin aluminum sheets can be cut to size using the scoring method. This method requires no power tools. First, lay an old tarpaulin on a flat surface, then place the metal sheet on top. Mark a straight line on the metal according to the dimensional requirements.
Next, run a sharp knife along the marked line in a back-and-forth scoring motion. To achieve a clean cut on aluminum, bend the sheet back and forth until it snaps apart. Apply gentle pressure at all times to prevent material damage or fracture defects.
Drilling Cutting Method
If all other cutting methods fail, weld cutting becomes the last option for cutting aluminum. It is a relatively simple cutting method that can cut aluminum sheets, aluminum tubes and aluminum profiles cleanly.
This cutting method does not require highly skilled workers or expensive equipment. First, mark the outline on the aluminum tube or aluminum sheet, then drill holes along the marked line, and finally finish the cut with an angle grinder or saw blade.
Cutting thicker aluminum sheets requires special drill bits. These drill bits are usually made of cobalt or tungsten carbide, which can withstand the high temperature generated during aluminum cutting.
The Best Methods for Cutting Aluminum
Cutting aluminum can be challenging, yet there are many simple ways to perform the cutting safely and more practically. Cutting techniques differ for thick sections and thin sections. Thick sections usually require more power, making power tools an excellent choice. Thin sheets can be cut easily with tin snips.
In earlier times, long chisels were also used, which was a difficult and time-consuming method. Modern cutting methods include waterjet cutting, as well as various types of grinders and saws.
Cutting Aluminum Sheet Metal to Size
Aluminum sheets with thin sections are generally easier to cut. Common cutting techniques include circular saw cutting, CNC machining, plasma cutting, metal shearing, and more.
Lubricant should be applied before cutting to avoid irregularities during the process. It is also critical to select the right aluminum cutting blade. Smaller-sized blades deliver clean cuts and higher dimensional accuracy for aluminum sheets.
Best Way to Cut 1/8 Inch Aluminum Diamond Plate
A circular saw is the best method for cutting 1/8 inch aluminum diamond plate. It is the fastest and simplest cutting technique. Blades with fine teeth provide excellent cutting results. Standard wood-cutting blades can also achieve precise cuts on thin aluminum plate.
Best Methods for Cutting Thick Aluminum
Thick aluminum sections can be cut with a spiral saw. Carbide saw blades are generally not recommended for cutting sections thicker than 3 mm. For better results, saw blades with a low tooth count and positive rake angle are recommended.
For thicker workpieces, engaging the metal with too many saw teeth at the same time poses cutting risks. Larger teeth can remove more material per cut. Applying lubricant on the metal surface helps reduce uneven cutting.
How to Cut Thin Aluminum Sheets
A jigsaw is the best tool for cutting thin aluminum sheets. Woodworking saws can also be used for this purpose.
Choosing the right blade for aluminum sheet cutting is critical; circular blades perform better than straight blades. The smaller the pitch of the saw teeth, the finer the chips produced, and it also prevents the aluminum sheet from bending during cutting.
What Are the Uses of Aluminum Cutting?

Can I cut aluminum with a CNC machine?
Any machinist who has ever broken a carbide drill bit will tell you there is a world of difference between simply cutting material and machining proper parts.
Aluminum is often regarded as an ideal material — lightweight, strong, and relatively soft. However, it is highly gummy and sticky. If your machine lacks sufficient rigidity or the feed rate is slightly off, aluminum will melt and cling to the cutting tool faster than you can hit the emergency stop button. While hobby-grade desktop milling machines can machine 6061 aluminum with ease, they frequently suffer from chatter marks and tangled chips.
