If you buy a new drill bit, the manufacturer should specify whether it is made for metal or not. This will be indicated on the packaging. Another way to distinguish a metal drill bit from a conventional one is by its wide-angled point. It will be black in color and be made of tungsten carbide, titanium, or cobalt.
Split point
Split point drill bits have a 135-degree angle on the tip, which allows them to drill through more difficult materials. The shaft also features two groves that push away debris from the hole and provide excellent cleaning ability. This design is especially useful for drilling metal and other hard materials, and is often preferred for use on cordless drills.
Split point drill bits are often more efficient than standard drill bits, as they use less total pressure and require less walking. They also have four cutting edges compared to two in a standard drill bit. This makes them far superior to walking drill bits, which often damage the material and make it difficult to repair.
Titanium nitride coating
Drill bits with a titanium nitride coating are durable and sharp, and are useful for a variety of applications. Titanium bits are hard and able to drill through materials such as plastics and wood. These bits also have a higher drilling speed than those without the coating. They also have an optimized flute, which increases bit strength and reduces bit walking. The coating also helps bits maintain their sharp edge, even after heavy use.
Titanium drill bits are manufactured from high-speed steel (HSS) and a coating of titanium nitride (TiN), a ceramic material. The coating increases the surface hardness and provides a thermal barrier, which reduces friction. These drill bits can provide increased productivity and reduced costs, and last three to six times longer than standard drill bits. They are also corrosion-resistant, and ideal for drilling steel, aluminum, magnesium, and wood.
Titanium CarboNitride coating
Titanium carbo-nitride coating on drill bits is one of the best ways to prolong the life of a drill bit. It has several benefits including improved machining speeds, corrosion resistance, and increased lubricity. It is also great for applications in high-alloy carbon steels and nickel-based materials.
Titanium carbo-nitride (TiCN) coating is non-toxic and complies with FDA guidelines. It is also used for medical applications, including implanted prostheses and hip replacement implants.
Carbide coating
One of the most common uses for a tungsten carbide coating is drilling in a variety of brittle materials. The coating reduces friction and heat transfer, and helps to extend the life of standard high-speed steel drill bits. Another use for a carbide coating is on stainless steel and cast iron drill bits. It increases the temperature resistance of a drill bit and can help improve precision drilling.
Drill bits with a carbide coating are more resistant to wear and can cut a variety of materials. They can also be used on difficult materials like fiberglass reinforced plastics and nonferrous metals.
Carbide coating on wood
Carbide-coated drill bits are more durable than regular drill bits. They are hard and can drill through almost any material. They also hold their edge longer than other drill bits. However, they can be expensive, especially compared to steel drill bits. Most carbide drill bits have a carbide tip, which is a small piece of hard material fixed to the bit. Solid carbide drill bits are increasingly popular in job shops and are also used for manufacturing printed circuit boards, where multiple holes with diameters of a few millimeters must be drilled.
Titanium is another metal that is frequently used for drill bits. This metal is corrosion-resistant and has a high heat limit. It also has a low fatigue limit. It is a versatile material for drill bits and has a long lifespan.
Carbide coating on glass
If you want to drill glass with greater precision, you should use a drill bit that has a carbide coating. This material is harder than diamonds and is suitable for drilling glass. Carbide-tipped drill bits have a spade-shaped point that can withstand the friction that results when drilling glass. However, you should use lubricant around the cutting area to prevent overheating the bit. Excessive heat can damage the glass or break it.
When drilling glass, you should wear protective eyewear and gloves. It is also a good idea to use a liquid lubricant to prevent overheating the bit. Moreover, you should mark the area where you plan to drill. Using a clear tape or pencil can help you mark the spot where you need to drill.
Carbide coating on tile
A tile drill bit coated with carbide is designed to drill through ceramic and porcelain tiles. Using carbide-tipped bits can reduce the amount of heat that can be generated, which is especially important for ceramic tile. The drill bit has double-helix flutes to minimize friction and a triangular shank to provide flat gripping surfaces on the drill chuck. FNEKER drill bits are available in metric sizes.
When choosing a tile drill bit, consider the material and configuration of the tiles. Terra-cotta tiles, for example, are relatively soft and can be drilled with a standard HSS masonry bit. However, ceramic and porcelain tiles are harder than terra-cotta, which is why a carbide-tipped masonry drill bit is the best choice for these types of materials. In addition, if you are working with glass tiles, consider using a spear point bit.
