In its 20-page patent application, the ARL proposes a cemented carbide additive manufacturing process based on powder bed fusion with selective laser melting, including a step of hot isostatic pressing to increase density of the part.

To say the tools are “tungsten carbide cutting tools” is a bit of a misnomer, though, as the material that makes up the tools is actually a composite rather than pure tungsten carbide.

When it comes to drilling through metal, using the correct drilling technique is essential. Applying excessive force or using high speeds can cause the drill bit to overheat and wear out prematurely. It’s important to find the right balance between speed and pressure to ensure a clean and efficient cut.

One material commonly used for high-quality drill bits is cobalt. Cobalt drill bits are known for their exceptional hardness and resistance to heat. They are ideal for drilling through tough metals like stainless steel and cast iron. The cobalt composition allows these drill bits to maintain their sharpness and durability even under high temperatures.

In addition to developing a way to more easily manufacture cemented carbide, ARL is interested in finding a replacement for cobalt (the “glue”) because it is expensive and reportedly carcinogenic.

When working on projects that involve welding dissimilar metals, selecting the right welding rod is critical to ensure strength, durability, and long-term reliability. Among the

One important factor to consider when using metal drill bits is the type of metal you are working with. Different metals have different hardness levels, which can affect the drilling process. For example, drilling through soft metals like aluminum requires less force and a higher speed, while drilling through harder metals like stainless steel requires more force and a slower speed.

“Manufacturing parts with the methods disclosed herein will eliminate the necessity to machine the parts after sintering,” the ARL researchers write. “Furthermore, the methods disclosed herein allow for spatially controlling binder content through the part material, which provides for functionally graded mechanical, magnetic, electrical, and/or sonic properties.”

High-quality drill bits for metal are designed to have optimal cutting speeds. They are engineered with sharp cutting edges and flutes that efficiently remove material as the bit rotates. The combination of the right cutting speed and sharpness allows these drill bits to effortlessly penetrate metal surfaces, reducing the drilling time and minimizing the risk of bit breakage.

To create parts made from cemented carbide, the composite material used in cutting tools, small tungsten carbide particles are typically mixed with other carbides, such as titanium carbide, tantalum carbide, and niobium carbide. These carbide powders are mixed and compressed in a mold along with powdered cobalt metal, which acts as the “glue” to hold everything together once the mixed powder is heated in a furnace and the cobalt melts.

Another important aspect of proper usage is using the correct size of drill bit for the job. Using a bit that is too small can cause the bit to break or wear out quickly, while using a bit that is too large can result in a sloppy and imprecise hole. It’s important to choose the right size bit for the specific task at hand.

High-quality drill bits for metal often feature advanced coatings and finishes that improve their performance. Titanium nitride (TiN) coating, for example, provides a hard surface layer that increases the drill bit’s resistance to wear and extends its lifespan. This coating also reduces friction, allowing the bit to glide smoothly through the metal, resulting in less heat generation and improved drilling efficiency. Similarly, drill bits with black oxide finish offer increased durability and reduced friction, making them suitable for drilling into various metals.

When selecting drill bits for metal, it’s important to consider certain features that contribute to their quality and performance.
