Best Cobalt Drill Bits UK Buying Guide
Size: Most of the time, long drill bits don’t last as long as short ones. The length of the unit makes it weaker and more likely to break. Shorter drill bits are less likely to break, spin, or twist. A shorter structure is stronger, and a drill bit with more twists makes a thicker and stronger structure.
Cobalt Value: For the structure to work well, it should have a lot of cobalt. When the amount of cobalt is higher, the unit can handle heat better and is stronger. For example, cobalt steel of grade M42 has 8% cobalt, while cobalt steel of grade M35 has only 5% cobalt.
Construction: Steel is the best metal to mix with cobalt because it makes the bit stronger and better able to cut through tough metals like stainless steel, cast iron, and others. Metal oxide should be used to coat the drill bit to make it more resistant to corrosion and wear.
Design: The shape of the drill bit is mostly about the point at the end. A split-point is the most common type, better for drilling through thick metal. The point can also be tapered, V-shaped, fish-shaped, or brad-shaped. Choose a style that fits the work you want to do.
Different kinds of cobalt drill bits
There are four different cobalt drill bits, and each one does something different. It is important to know how We should use each bit type.
- Twist: The grooves on twist bits are at an angle and wrap around the drill shaft. These angles have sharp edges that help the bit dig into the material. Twist drill bits are for general use, which means We can use them to drill into a wide range of materials. Cobalt twist bits are strong enough to drill through tough metals quickly. They come in many different sizes, and some sets have as many as 30 pieces.
- Countersink: Countersink drill bits make shallow holes that are angled to match the tapered head of the fastener. This lets the head of the fastener sit flush with the material. We can use countersink bits made of cobalt to make countersink holes in hard metals. Unlike twist drill bits, which have self-starting tips, We can’t use countersink bits to drill into a material without an existing hole.
- Counterbore: With a counterbore drill bit, you can make holes that let the head of a fastener sit below the material’s surface. Counterbore drill bits make a bigger hole at a shallower depth than countersink bits, making an angled hole for fasteners with angled heads. With a counterbored hole, the head of the fastener can rest on a flat ridge.
- Cobalt Step: Step drill bits made of cobalt make holes in sheet metal. Step bits let you control the size of the hole by making it bigger as it goes through the metal. We can use a step bit on metal sheets up to 1/4 inch thick.
The Advantages of Cobalt Drill Bits
- Drill through hard things: Steel is added to cobalt drill bits to give them a strong structure that can drill through tough materials like stainless steel and titanium. Most of the tools are made of cobalt M35- and M42-grade, making them more durable and resistant to heat when drilling through hard surfaces.
- Versatile application: We can use most cobalt drill sets with almost any electric tool. They come with bits of different sizes that fit securely in the power tool so that they don’t spin or twist when drilling hard things. We can also use them to drill through plastic, wood, most metals, and even rough surfaces.
- Enjoy DIY projects: Cobalt drill bits are safe and useful tools for anyone who likes to do their home repairs and needs a set of portable drill bits with a lot of accuracies. Cobalt drills are resistant to wear and have markings that tell you which size is best to use. They are the best tools for use around the house because they last longer than regular bits and can be used in a regular drill gun.
Common Questions
- Who makes the Cobalt drill bits?
There are a lot of well-known and world-class names in the business of power drills and attachments.
Bosch, DEWALT, and IRWIN are the cobalt bit brands you can trust the most. - What drill bits are harder than cobalt?
Titanium drill bits are harder than cobalt and last longer than regular HSS drill bits.
These are also good at cutting through tough metal. But We can’t sharpen titanium drill bits, and the coating doesn’t last long. On the other hand, Cobalt drill bits can be sharpened and have a coating that lasts longer. - Are cobalt drills the best?
Cobalt drill bits are very strong and can easily cut through cast iron, bronze, stainless steel, titanium, and other hard metals when it comes to strength. Normal HSS drill bits don’t last as long as cobalt bits with good cutting edges. Even these have a stronger head than titanium drill bits and can be used repeatedly.
