Cutting speed refers to the speed at which the cutting edge of the router bit moves across the surface of the material. It is typically measured in surface feet per minute (SFM) or meters per minute (MPM) and directly influences the quality of the cut, tool wear, and the overall efficiency of the machining process. When it comes to aluminum, determining the correct cutting speed is vital for balancing material removal rates and tool longevity.

The Ultra-Shear 1/2" Shank Solid Carbide Router Bit line-up is growing.  We now have 4 cut lengths in 1/2" diameter (1", 1-1/4", 1-1/2" and 2") and three reduced cutting diameter sizes (1/4", 5/16" and 3/8") in 1-1/4" cut length. All 7 dimensions are available in both Up-Cut and Down-Cut versions. Whether you’re using a trammel, an edge guide, a router table, a horizontal router system or a CNC, these are some of the most versatile straight bits you can use. You'll get exceptionally clean cuts and outstanding tool life from these American-made top-quality bits.

Ensure that your router bit is sharp before cutting. A dull bit can produce more friction, causing heat buildup and material sticking. Regularly inspect your bits and replace them as needed.

Up-Cut or Down-Cut? Up-Cut bits pull the chips out of the kerf more effectively. They’re a great choice for dadoes, slotting and full-edge cutting in solid wood. Down-Cut bits slice down into the material so surface fibers don’t get lifted. This is particularly important on cabinet grade plywood and a great choice for rabbeting. A Down-Cut bit will give you a super clean edge in even the thinnest surface veneers.

Router bit manufacturers often provide recommended cutting speeds for different materials, including aluminum. These recommendations offer a starting point, but adjustments may be needed based on specific project parameters. For aluminum, carbide bits typically allow for speeds between 300 and 1200 SFM, while HSS bits should operate at lower speeds, around 200 to 600 SFM.

Understanding how aluminum interacts with your router bit at different speeds will help you avoid these issues, ensuring cleaner cuts and longer-lasting equipment.

Several factors come into play when determining the optimal cutting speed for an aluminum router bit, including the type of aluminum alloy, the router bit material, and the overall tool geometry. Below are the primary factors to consider:

Choosing the correct RPM for your router bit is just as critical as cutting speed. For aluminum, start by consulting the manufacturer’s guidelines and making adjustments based on your specific setup. As a general rule:

Don’t settle for inferior quality imported bits to save money. Woodpeckers uses state-of-the-art CNC grinding equipment, the highest quality solid carbide blanks and ultra-fine grinding wheels to produce American-made router bits at extremely competitive prices. The days of paying extra for middle-man markups are over. Buy direct from the manufacturer and pocket the savings.

For mortise and tenon work, particularly through-mortise joints, long cut length is essential. That’s when you'll need the 1-1/2" and 2" cut length 1/2" diameter. In addition to generous cut length, these bits are held to very strict tolerance for dimensional accuracy…in other words they’re perfect for CNC machines and horizontal routers like the Multi-Router and PantoRouter.

Aluminum is a relatively soft, ductile material compared to harder metals like steel or titanium. While this makes it easier to cut, it also poses specific challenges. Aluminum tends to be more “sticky” than other metals, meaning it can gum up the cutting edges of router bits if the cutting speed and feed rate aren’t correctly set. This can lead to rough finishes, decreased tool life, and even tool breakage.

Pushing the bit too hard can result in tool deflection or breakage, especially at higher speeds. It’s better to perform several light passes rather than a single heavy cut.

The latest additions to the line-up are the reduced cutting diameter bits. When you need the cleanest cuts at smaller diameters, stepping down from 1/2" shank maintains the mass and collet geometry you need.  These bits deliver great surface finish on both the sides and bottom of your cut. They're the ideal choice for dadoes, grooves and rabbets as well as machining outside perimeters on CNC systems.

Choosing the right cutting speed for an aluminum router bit requires careful consideration of several factors, including the alloy type, bit material, and tool geometry. By calculating the proper cutting speed and adjusting your machine settings accordingly, you can achieve smooth finishes, minimize tool wear, and improve overall machining efficiency.

Determining the correct cutting speed for aluminum router bits involves considering the factors mentioned above and applying them to your specific machining environment. Below are general steps to help calculate the cutting speed for aluminum:

Feed rate is the distance the router bit moves through the material in one revolution, usually measured in inches per minute (IPM). For aluminum, balancing cutting speed with feed rate is essential to prevent the tool from overheating or getting clogged with material. Too slow of a feed rate combined with a high cutting speed can cause excessive heat buildup, damaging the bit and the material.

Always perform test cuts to verify that your setup produces smooth finishes and consistent results without causing excessive tool wear.

Different aluminum alloys have varying hardness levels, which means they respond differently to cutting. Softer alloys like 1100 and 3003 allow for higher cutting speeds, whereas harder alloys like 7075 and 2024 may require a reduction in cutting speed. Knowing the specific grade of aluminum you’re working with will help you adjust your cutting speed accordingly.

When machining aluminum, using the correct cutting speed with your aluminum router bit is essential for achieving high-quality finishes and optimal tool life. Whether you’re new to CNC machining or looking to fine-tune your cutting process, understanding the key factors influencing aluminum cutting speed is crucial.

Using a coolant or lubricant can help reduce heat buildup during high-speed machining of aluminum, improving both the cutting speed and the lifespan of your router bit. Coolants like mist sprays or oil can also prevent material from sticking to the bit, which is a common issue with aluminum.

The design and geometry of the aluminum router bit play a significant role in determining the appropriate cutting speed. Bits with more aggressive flute geometries allow for faster material removal, while those with more conservative designs may require slower speeds to maintain control.
