I love the word Jobber. Seriously, say it out loud right now. I’ll wait. Jobber. Hilarious. But they are also wonderful, useful tools. They are probably the most common type of drill bit on the market today. Generally speaking, the length of a jobber flute is 8-12 times the diameter of the drill bit. That’s what makes it a jobber. It also refers to someone contracted to lose a professional wrestling match, but that’s another post entirely.
What is a jobber drill bit?
A jobber drill bit is a specially designed bit used to drill holes in materials such as wood, plastic, and metal. The jobber drill bit has a pointed end that is specifically designed to create smaller holes than a standard drill bit. This makes it perfect for drilling through tight spaces or into hard-to-reach areas.
A jobber drill bit is a special type of drill bit that is designed for use in drilling through hard materials, such as concrete or metal. Jobber drill bits are usually smaller than standard drill bits and have beveled edges on both the front and back sides of the bit. This allows them to better cut through hard materials without gouging them. A jobber drill has a shorter, wider diameter than a standard drill bit. This makes it better suited for drilling through hard materials like concrete or stone. Jobber drill bits are also often less expensive than standard drill bits, making them a good choice for projects where money is tight.
Size and Length
When shopping for a jobber, there is a wide variety of materials, manufacturers, and sizes. The sizes can be especially confusing, so here’s a quick rundown. Fractional, Letter, Metric, and Wire all refer to the measurement systems used for Jobbers of regular length. In other words, it’s just different ways to describe how wide the bit is. Fractional bit sizes measure bit size in increments of 1/64 inch up to 1 inch, 1/16 inch to 3 inches, 1/8 inch up to 3 ¼ inches, and just one more ¼ inch increment to 3 ½ inches. The length of the bit size is recorded as irreducible fractions (1 7/32 instead of 39/32).
Number and Letter Sizes measure their bits in…well…numbers or letters. In other words, you can have a size 1 through 80 or a size A through Z. Wire Sizes are another set of measurements starting at one and then increasing by whole numbers. Finally, metric uses standard metric measurements. Mechanics Length, Reduced Shank, and Screw Machine Length refer to the Jobber’s length. A Mechanics Length set is shorter in the flute than the average Jobber. It’s sturdier because of this and is better for drilling through harder materials. Jobber length is usually preferred for drilling through wood. Reduced Shanks are pretty much self-explanatory. The shank is shorter to fit into certain machines. Lastly, Screw Machine Length, like the Mechanics Length, will have a shorter flute. This means they are less likely to snap during use but will drill shallower holes.
Types of jobber drill bits
There are three main types of jobber drill bits: standard, forstner, and countersink. Each has its own advantages and disadvantages.
- Standard jobber drill bits are the most common type. They’re designed to do general drilling tasks, such as making holes in wood or plastic. Standard jobber drill bits are versatile and can be used with a variety of tools, including drills and screwdrivers. Standard jobber drill bits are a great option for DIYers and those who need a wide range of drilling capabilities. They are affordable and often have good quality, making them a good choice for many tasks. Additionally, they can be used with a wide variety of tools and machines, making them versatile and easy to use.
- Forstner jobber drill bits are similar to standard jobber drill bits but have one key advantage: they’re specifically designed for making holes in wood. Forstner jobber drill bits can be used with a variety of tools, but they’re best suited for use with a woodworking tool called a Forstner bit holder.
- Countersink jobber drill bits have a specifically shaped countersink section that is designed to reduce the amount of damage that is done to the surrounding material when the bit is drilled into it.
Why use a jobber drill bit?
- They are great for drilling small holes and tight spaces.
- They can be used in a variety of applications, including woodworking, metalworking, plumbing, and more.
- They are easy to use and maintain, making them a great option for beginner drillers.
- They are also affordable, making them a good choice for budget-minded homeowners and professionals alike.
What does a jobber drill bit do?
A jobber drill bit is a small, inexpensive tool that’s often used to quickly drill small holes in various materials. This type of bit has a number of different functions, including the ability to make precise, tiny holes in hard materials and the ability to make larger holes in softer materials.
One common use for a jobber drill bit is drilling small holes in wood. By using a jobber drill bit, you can create accurate, tiny holes that will allow screws and other fasteners to easily secure the wood panel into place. Another common use for a jobber drill bit is drilling large hole in soft materials like plastic and fiberglass. By using a jobber drill bit, you can create large enough holes that screws and other fasteners will easily pass through them.
Benefits of using a jobber drill bit
A jobber drill bit is a versatile tool that can be used for a variety of tasks. It is a great option for drilling into hard materials like tile and stone. It is also ideal for drilling small holes in soft materials like wood or plastic. However, here are some key benefits of using a jobber drill bit so far, Take a look at them:
- A jobber drill bit is a type of drill bit that is designed to be used with a rotary tool. This type of bit has a smaller Shank size than other types of drill bits, which makes it easier to insert into the workpiece.
- Another benefit of using a jobber drill bit is that it can help you make more accurate holes in your workpiece. Because the shank is smaller, the bits are less likely to wander during drilling and result in more accurate holes.
- Additionally, because jobber drills are designed for use with rotary tools, they tend to be more powerful than other types of drills. This means that you can easily remove large pieces of material from your workpiece with one smooth thrusting motion.
Conclusion
In conclusion, the jobber drill bit sizes vary depending on the task at hand. For instance, for drilling into hard materials like concrete or masonry, a larger bit is needed. On the other hand, for drilling through soft materials like wood or plastic, a smaller bit is more appropriate. It is important to choose the right sized bit for the task at hand in order to avoid complications and potential injuries.
