Carbide drill bits are used to drill into the hardest materials, including masonry, but because of brittleness, they are only used in automated production.

Solid carbide drill bits are often made from tough tungsten, which makes them perfect for drilling. This premium material comes at a cost but is extremely durable and keeps its sharp edge for longer than most other drill bits.

However, any drill bit is going to gradually wear and carbide drill bits are no different. Machine shops are used to sharpen these and extend their life. Due to their hardness, solid tungsten carbide drill bits last a lot longer than most other drill bits. Hardened steel drill bits are not quite as long-lasting as carbide drill bits that can save money and time in the long-run.

As carbide drill bits are not cheap to produce, they are frequently recycled to cut costs. Carbide recyclers use scrap carbide to create new carbide drill bits.

The Magnum Super Premium drills will substantially outperform cobalt drills in work hardening stainless steel applications. This performance advantage is the result of construction differences between the two types of drills. Cobalt drills, manufactured to Type J NAS907 specs, has a very thick web. This web is necessary to limit breakage of the brittle cobalt steel. Magnum Super Premium drills are made of special Hi-moly tool steel, which is much tougher than cobalt steel. The web on a Magnum Super Premium drill can be thinned considerably due to the toughness of the steel.A Magnum Super Premium drill with its thin web will penetrate the work hardening stainless fast enough to continually cut beneath the chip which is hardening from deformation. This means the drill is cutting softer steel. The cobalt drill, with its thick web, cannot be fed at a fast enough rate to cut beneath the area which is hardening. As a result the cobalt drill is continually drilling into hardened steel.

Carbide drill bits are expensive by comparison but will be more effective on certain materials and will withstand more use without wearing. They also create sharper and finer edges than many other drill bits. Carbide tipped drill bits are a cheaper alternative that will do a good job for most projects and will get the job done to a high standard in most cases.

Another type of carbide drill bit is known as cemented carbide. These drill bits are made from grains of tungsten carbide, other material particles, and metal cobalt. If additives are not used, the carbide tool will chemically react with ferrous materials and create a crater in the tool.

Solid carbide drill bits for hardened steel aren’t always made entirely of tungsten carbide. Some drill bits are coated with tungsten carbide rather than being formed entirely from the material. These are particularly useful in mining, construction, and farming due to their longevity.

Carbide drill bits are made from tungsten carbide, a compound of carbon and tungsten. This material provides faster cutting speed, more durability, and longevity. As a result, it’s a popular choice for tough jobs.

Carbide drill bits can withstand high temperatures, more than cobalt or HSS. They are best used in industrial manufacturing and are generally not needed for DIY projects.
