Are you wondering what jobber drill bits are and how they can benefit your projects? Jobber drill bits are specially designed and crafted to be used in industrial projects. They are the most common type of drill bit and are the industry standard for many applications. Jobber drill bits are made of high-speed steel, and they are designed to easily penetrate and drill into different materials, such as wood, plastic, and metal. They also offer superior precision and control, making them ideal for a wide range of projects. In this article, we will discuss the benefits of using jobber drills and the different types of jobber drill bits available.

Definition of Jobber Drills

Definition Of Jobber Drills

Jobber drills are a type of twist drill bit characterized by their fluted design, which allows them to efficiently remove material from a workpiece. These drills are among the most popular and widely used drill bits today and are typically used for drilling holes in wood, metal, and other materials.

The main feature of jobber drills is their flute design, which consists of a straight flute and a helical flute. The helical flute is responsible for cutting away material, while the straight flute helps to clear away chips and debris as the hole is being drilled. The flutes also help to reduce friction and heat build-up while drilling.

Jobber drills are available in a variety of sizes and shapes, depending on the project requirements. The most common sizes range from 1/16 inch to 1 inch diameter, while larger sizes are available up to 4 inches in diameter. The shape of the drill bit can also vary, with straight, spiral, and tapered designs available.

Feature Description
Flutes Straight and helical flutes for cutting and clearing material.
Size Most commonly 1/16” to 1” and up to 4”.
Shape Straight, spiral, and tapered.

Jobber drills are an essential tool for any DIY project or professional job, as they provide an efficient way to drill holes in a variety of materials. With their wide range of sizes and shapes, jobber drills are a versatile and reliable tool for any job.

How to Use Jobber Drills

How To Use Jobber Drills

Step 1: Select the right size and type of drill bit for the job. Jobber drills come in a variety of sizes, styles and types of cutting surfaces. Depending on the material you are drilling, you’ll need to choose the appropriate bit for the job.

Step 2: Secure the material you are drilling in a vise or clamp. It is important that you secure the material firmly before beginning the drilling process.

Step 3: Use a center punch to make a starter hole. This will make it easier to insert the drill bit and begin drilling.

Step 4: Set the drill speed and start drilling. Jobber drills require a slower speed than traditional twist drills, so be sure to adjust the speed accordingly.

Step 5: Once the hole is complete, back the drill out and remove the bit. Inspect the hole for any burrs or rough edges that may need to be cleaned up.

Step 6: Clean the drill bit with a brush or cloth to remove any debris.

Step 7: Replace the drill bit in its case for storage.

Jobber Drill Type Material
High Speed Steel Wood, Plastic, Aluminum
Cobalt Cast Iron, Stainless Steel, Hardened Steel
Carbide Titanium, Inconel, Iron

Best Practices for Using Jobber Drills

Best Practices For Using Jobber Drills

  • Ensure Proper Fit: Jobber drills should be the right size and shape for the job. Measure the diameter of the hole and select the right size and shape of jobber drill.
  • Secure the Workpiece: Before beginning, secure the workpiece to prevent it from moving. This will help ensure accuracy and reduce the risk of injury.
  • Use Proper Technique: When using a jobber drill, ensure that you use the correct technique. Keep the drill bit perpendicular to the workpiece and keep the drill bit in constant contact with the material.
  • Use the Correct Speed: When drilling with a jobber drill, use the correct speed for the material. Too slow a speed can cause the drill bit to burn out, while too fast a speed can cause the drill bit to skip or chatter.
  • Use Lubrication: To increase the life of a jobber drill, use lubrication when drilling. This will help reduce friction and prevent the drill bit from becoming too hot.
  • Keep the Drill Bit Clean: After each use, clean the jobber drill bit to remove any debris. This will help maintain the drill bit and increase its life.
