A drill bit is a tool used to make holes in a range of materials, such as wood, metal, masonry or plastics. It consists of a cutting edge at the tip of a cylindrical shaft that is attached to an electric drill. The drill provides the rotational force needed to create a hole.
Drill bits come in various shapes and sizes, designed for different materials and applications. For example, masonry drill bits are used to drill through bricks and concrete, while metal drill bits are used to drill through steel and other metals.
Choosing the right drill bit for the job is essential to ensure an accurate hole size and to avoid damage to the material being drilled. Drill bits are also available with different coatings, which can improve their performance when drilling through tough materials.
Straight Shank Hss Twist Drill Bits
Twist drill bits are one of the most widely used hole processing tools, usually in the diameter range of 1 to 13 mm. They consist of the working part, neck, and handle. The working part has two spiral grooves, which are shaped like a twist, hence the name. These twist drill bits are used to create a circular hole in a workpiece through its rotational cutting relative to a fixed axis.
Straight shank twist drill bits are the most common type and are used in a wide variety of applications.
No matter what the application, twist drill bits provide an efficient and cost-effective way to create holes in a workpiece.
Step Drill Bits
Step drill bits are made of high speed steel and are mainly used for drilling thin steel plates within 3mm.
One step drill bit can be used in place of multiple drill bits to process holes of different diameters according to needs and can realize the one-time processing of large holes. There is no need to replace the drill bit.
According to the flute shape of the product, step drill bits can be divided into two types: straight flute and spiral flute. And according to the number of product edges, step drill bits can be divided into the single flute, double flutes, three flutes, and others.
Step drill bits are an essential tool for anyone who frequently works with thin steel plates. Their versatility and efficiency make them a valuable addition to any toolbox.
Morse Taper Shank Drill Bit
Taper shank twist drill bits are the most widely used type of hole processing tool and are usually used for drilling holes in a wide range of diameters, from 6 mm up to 100 mm. They consist of two main parts: the working part, which contains two spiral grooves that give the drill bit its twisting motion; and the shank, which tapers towards the end.
Different taper shank drill bits have different morse tapers, which dictate the sizes of the holes that they can drill.
While taper shank twist drills are more expensive than their straight shank counterparts, their tapered shanks make them much more stable and less likely to slip during use. As a result, taper shank twist drills are the preferred choice for many professionals.
Double Ended Drill Bit
Double-ended drill bits are an essential tool for any home improvement project, whether you’re drilling through wood, metal, or stone. With two cutting edges, these bits provide twice the life of standard drill bits and can easily drill through even the most stubborn materials.
In addition, double-ended drill bits are designed to work more efficiently, so you can get the job done faster with less effort. Whether you’re a professional contractor or a do-it-yourselfer, double-ended drill bits are a must-have for your toolbox.
Reduced Shank Drill Bit
The most common type of drill bit is the straight shank. The whole of the drill bit, shaft and shank, is usually of the same diameter. Straight shanks can be reduced so that they can be fitted in chucks that are not able to chuck the full diameter. These narrower shanks are referred to as reduced shank drill bits.
Reduced shank drill bits are available in 1/4” reduced hex shanks, 3/8” reduced shanks, and 1/2”. The most common type of reduced shank drill bit is the Silver & Deming bit with a 1/2” reduced shank. Reduced shank drill bits are an essential part of any machinist’s toolkit as they allow for greater flexibility in drilling applications.
Short Length Stubby Drill Bits
Short length drill bits, also called screw-machine-length bits, are the shortest standard length drill bits.
Short length drill bits are used in other applications where a short, rigid bit is needed. Their shorter flute length and shorter overall length compared to a standard jobber length bit results in a more rigid drill bit, reducing deflection and breakage.
Short stubby length drill bits are perfect for use in right-angle drills and for tight spaces.
Extra Long Drill Bits
Since extra long drill bits have a longer overall length and longer flutes, they can create deeper holes than standard jobber-length drill bits.
In addition, the extra length of the shank on extended-length drill bits gives them more reach than taper-length drill bits, making them ideal for drilling into hard-to-reach workpieces.
While they may be slightly more expensive than shorter drill bits, extended-length drill bits are an essential tool for any serious woodworker or metalworker.
Countersink Drill Bits
Countersink drill bits are used to cut countersinks, which are small, cone-shaped holes cut into an object in order to allow the head of a screw, bolt, or nail to sit flush with the surface.
The chamfer angles of countersinks can vary, depending on the tool used or the chamfer angle of the screw or bolt.
Chamfer angles are typically 60, 82, 90, 100, 110, or 120 degrees, and the angle is measured from either end of the hole opening. Thus, countersink drill bits can be a helpful tool in a variety of applications.
Counterbore Drill Bits
A counterbore is a tool that is used to create a hole for the body of a fastener, as well as a larger sized cavity for the head of the fastener.
When selecting a counterbore drill bit, it is important to choose the correct size based on the specific fastener that will be used. counterbore drill bits are an essential tool for any individual who frequently works with fasteners.
Screwdriver Drill Bits
Screwdriver drill bit is a type of drill bit that is used to screw screws. There are many different types of screwdriver bits, each designed for a specific type of screw.
The most common types of screwdriver bits are slotted and PH2.
When choosing a screwdriver bit, it is important to select the correct size and type for the screw you are using. Using the wrong type of screwdriver bit can damage the screw or the screwdriver itself.
Tile Drill Bits
Tile drill bits are designed for making holes in tiles, glass, ceramics, concrete, brick walls, wood, plastic, etc.
When drilling a tile with a tile drill bit, the temperature of the drilled part will rise sharply, which can easily lead to uneven heating and cracking of the tile.
Therefore, when drilling, you can add some water to the drill to reduce the temperature, which can also play a role in lubricates and reduces drill wear and burnout.
Multipurpose Masonry Drill Bits
You might think that you need different drill bits for different materials. However, multipurpose masonry drill bits are tough enough to get the job done no matter what you’re drilling through.
Whether you’re dealing with wood, metal or tile, these drill bits will make quick work of it. And because they don’t require a separate bit for each material, they’re also more cost-effective. So if you’re looking for a versatile and affordable option, multipurpose masonry drill bits are the way to go.
