In the context of drill bits, a jobber refers to a length of drill bit with a straight shank; they are the more common type of drill bit. Jobber drill bits are designed to work with a variety of materials and come in a variety of sizes and lengths.
Their straight shank allows them to be securely held in the drill chuck, which makes them suitable for use in portable drills. Jobber drill bits are available in High-Speed Steel (HSS), cobalt, and titanium, with HSS being the most affordable and common option.
Because jobber drill bits are readily available, they are the preferred choice for a multitude of general-purpose drilling applications.
What is the difference between jobber and mechanics drill bits?
Jobber drill bits, also known as twist drill bits, are the most common type of drill bit and are used for a variety of general purpose drilling applications. They feature a cylindrical shaft with a sharp, round point at the end that allows them to easily drill into a variety of materials without slipping.
The length of the jobber drill bit shaft varies in order to accommodate different depths of material, ranging from reduced shank bits to extra-long drill bits.
Mechanics drill bits are specially designed to perform more complex drilling operations, such as drilling out broken bolts or stripped screws. They feature a variety of different design elements that allow the bit to better grip the material being drilled and apply more torque, making them more efficient than jobber drill bits.
They often feature a split-point design, located at the distal end of the bit, which assists in keeping the material from slipping while in use. Mechanics drill bits also come with spiral flutes and wide land marks, which helps to ensure that cuttings are quickly removed from the hole, thereby increasing the rate of speed and accuracy while drilling.

What are the 5 types of drill bits?
There are five main types of drill bits which can be used for a variety of purposes:
1) The twist drill bit is the most common and versatile drill bit. It is designed with two cutting edges that cut material as the bit rotates. These drill bits typically have a cylindrical shank and tapered tip and come in many different sizes and shapes.
2) The masonry drill bit is designed for making holes in concrete, brick, and other masonry materials. These drills bits have a special carbide tip and fluting that cuts better than twist drill bits.
They also have a larger diameter and flatter face for spot drilling.
3) The spade drill bit is designed for cutting large, flat-bottomed holes in wood. It is essentially a flat, wide piece of metal with a single cutting tip on the end. These drill bits come in a variety of sizes and are great for making shelf supports and other woodworking tasks.
4) The brad point drill bit is designed for making clean, accurate holes in wood. These drill bits have a pointed tip and two brad-like cutting edges on the sides of the bit which helps to keep it centered in the workpiece.
5) The all purpose drill bit is, as the name implies, an all-purpose drill bit. It has a unique design that allows it to cut a variety of materials including wood, plastic, metal, and other composite materials.
These drill bits come in a wide range of sizes and shapes and are great for projects that require versatility.
What kind of drill bits go through metal?
When it comes to drilling through metal, there are three main types of drill bits that are most commonly used: twist drill bits, masonry bits, and step drill bits.
Twist drill bits are the most commonly used and are available in many sizes and designs, allowing you to drill precise holes into a range of metals. These bits have a spiral-shaped cutting edge that helps cut through metal.
The two most common types of twist drill bits are high-speed steel (HSS) and carbide. HSS twist drill bits are the least expensive and best suited for drilling softer materials, like aluminum, brass and copper.
Carbide twist drill bits are more expensive but are more durable, allowing them to stay sharper longer and making them more effective for drilling harder metals.
Masonry bits, which are also referred to as percussion bits, are designed with a pointed tip and have a fluted edge. This will help you drill into metal, stone, concrete, and brick. The tips of masonry bits are made from case hardened steel or tungsten carbide, which can be used for harder materials like stainless steel.
Step drill bits are also referred to as Unibits due to the fact that they can be used for multiple purposes. Step drill bits are made from high-speed steel (HSS) and fluted along their length. The fluting provides cutting edges and allows for easy removal of the metal shavings.
Step drill bits are able to cut through metal cleanly, making them suitable for a variety of materials such as aluminum, brass, copper, and stainless steel.
Overall, drill bits that are designed for metal drilling do so in a variety of ways. This being said, the type of drill bit you need will depend on the material you are drilling. Make sure to check the specifications of the bit you are using to make sure it is suitable for the type of metal you are drilling.
What drill bits are for stainless steel?
Stainless steel is a highly durable material and requires special drill bits in order to drill through it. The best drill bits for stainless steel are those made from cobalt, titanium, or high-speed steel.
Cobalt drill bits are made from an alloy blend, which makes them ideal for drilling into hard and abrasive materials, including stainless steel. Titanium drill bits are known for their durability and long life, and therefore are ideal for stainless steel.
High-speed steel drill bits are the most common type and are used for less hardened materials, however, they are still suitable for drilling stainless steel. When drilling into stainless steel with any of these drill bits, it is important to lubricate the bit with oil to cool it and clear away the debris.
Additionally, a reverse cutting drill bit, which has upward-facing spirals, is often recommended when drilling stainless steel as they help to reduce material build-up.
What are parabolic drill bits used for?
Parabolic drill bits are tools used for drilling holes in a range of materials including wood, metal, plastic, and reinforced concrete. They are engineered to create a hole that has a curved “parabolic” shape, which results in a decrease in drill-bit pressure and enhanced drilling performance.
This makes it a popular choice among tradespeople dealing with tougher materials like stainless steel and fibreglass, as well as those needing more precision while drilling. The parabolic drill bit is a multi-purpose tool that covers a wide array of applications.
From agricultural equipment to construction and landscaping work, many projects can benefit from the greater drilling capacity and enhanced speed that the parabolic drill bit offers. The curve allows the bit to cut through more quickly and efficiently while also helping to reduce heat buildup, which can be a problem with traditional straight drill bits.
This makes the parabolic drill bit a reliable choice for many tradespeople looking for a reliable and versatile drilling solution.
Who makes the cobalt drill bits?
Cobalt drill bits are made by various manufacturers, including: DeWalt, Neiko, Rotary, Milwaukee, and Titan. The bits are primarily made with a cobalt alloy, which is a blend of several metals – primarily cobalt, molybdenum, and tungsten.
This alloy is heat treated, which makes it more durable and able to handle higher temperatures than conventional steel, and therefore it is an ideal choice for drilling into hard materials such as stainless steel.
In addition to being heat treated, cobalt drill bits are machined with various features that make them suitable for different types of drilling operations. For example, some drills are designed with a spiral groove, which helps direct the drill bit and guide it through material.
Other drill bits may be designed with sets of multi-faceted cutting edges, designed to rapidly remove material from where the bit is drilling.
What lengths do drill bits come in?
Drill bits come in a variety of different lengths and sizes. The most common length of drill bits range from 1/16 inch to 1/2 inch, with the most common being 1/4 inch. Longer bits, from 6 inches up to 24 inches, are available as well and can be used with rotary drills or drill presses.
These longer bits are used for cutting through very thick materials and are primarily used in woodworking and metalworking. Some specialty drill bits can come as long as 60 inches, and are used for extremely deep and precise drilling.
Additionally, small micro drill bits, which range between 0.2 to 1.5 inches in length, are available and are used for drilling very small and precise holes.
How long are mechanics length drill bits?
The length of mechanics length drill bits range based on the size and type of bit you are looking for. For example, twist drill bits typically measure between two and six inches, while screw machine drill bits are around 4-5 inches in overall length.
In addition, jobber length drill bits have been known to reach lengths of up to 12 inches, depending on the type and size. It is important to note that the flute length of any drill bit – which are the parts that extend past its tip – will always be shorter than the total length measured from its tip to the bottom of its overall length.
What does jobber length mean?
Jobber length is an industry term used to describe the standard length of a twist drill bit. Jobber length drills are the most common length and they measure between 6 and 14 inches in length, depending upon the size of the drill bit.
These long length drill bits allow for a greater range of accuracy and control when drilling into materials. The jobber length also helps to provide increased stability through their straight shank design, which helps to reduce working deflection.
Jobber length drill bits are used for a wide range of drilling applications, such as drill presses, hand drills, drivers, and specialized drilling equipment. They are often used in the construction, automotive, and manufacturing industries due to the strength and flexibility that they provide.
