Instructions: Slowly dial up the RPMs on your router to the recommended maximum. Then, dial back if needed to find the “sweet spot”. The sweet spot is the speed at which the least resonant vibration is present. If the sweet spot cannot be achieved within 5,000 RPMs of the max, check the collet for residue or other debris and start over.

This carbide straight router bit features a cutting diameter of 1/4" and a cutting length of 1-1/2" with an overall length of 3-5/16". The shank is 1/4" in diameter.

- Aluminum Cut Carbide Burrs: Ideal for softer materials like aluminum, these burrs prevent loading and provide clean cuts without material buildup.

Solid carbide tipped insert router bits are very durable, versatile and long lasting. The solid carbide insert can be manufactured with very small diameters while still maintaining structural strength. Best for use in detailed applications, inlays and fine grooving. The solid carbide tip is welded into a hardened steel shank.

Carbide burrs are known for their exceptional durability, versatility, and cutting performance. These burrs are made from ultra-hard tungsten carbide, allowing them to cut through a wide range of materials, including metals, plastics, wood, and more. The unique properties of carbide make our burrs exceptionally wear-resistant, ensuring that they maintain their sharpness and effectiveness over time.

• 2 Flute End Mills for Soft Materials • 4 Flute End Mills for Steel It is important to know that although Carbide tools does manufacture a line of “Conventional” end mills with 30° Helix Angles these “Conventional” end mills are designed to be run on manual machining centers and CNC machines with lower RPM spindles. Carbide Tools prides itself on our line of High Performance End Mills that come in a variety of geometries to match the material and machine’s capability. As machining centers RPM, Feed Rates and Rigidity continue to increase tool paths can be varied to such a great degree that standard feeds and speeds simply act as a starting point to consider. The machine operator will be able to tune the end mill to the application by increasing spindle RPM or feed rates to find the sweet spot of the end mill and maximize its speed and life. All of our High Performance End Mills have been designed to run best using modern Trochoidal or High Speed Machining tool paths. The tools prefer higher RPMs with a shallower cut but at high feed rates. There are several “High Speed Machining” programs or apps available to help you calculate your speeds and feeds based on material being machined, number of flutes, helix angle and coating for example that can really help you maximize the performance of each end mill. We recommend you look into one of these apps but, the numbers below are a good place to get you started. But the machinist will find the right combination of speeds and feeds for each tool. Solid Carbide end mills provide the machine operator greater rigidity, a stronger cutting tooth and better resistance to heat than high speed steel. Because of these qualities it can be run at higher speeds or surface feet/minute (SFM). Softer materials such as Aluminum, Brass, Copper and Plastic should be run at higher SFM. Typically the finish of the material being milled can be improved by increasing the SFM. Slower speeds should be used to mill harder materials like Steel, Cast Iron, Tool Steels and Nickel based alloys such as Stainless Steel and Inconel. Feed rates also vary by material as well as the diameter of the end mill and the number of teeth on the end mill. Peripheral milling is typically done at higher feed rates than slot milling. Softer materials can be milled at higher feed rates than hard materials. Typically feed rates should be increased to eliminate chatter.
