What Are Drill Bit Blanks?

Drill bit blanks are an essential component in the manufacturing of cutting tools, specifically HSS drill bits, Carbide drill bits, and drill bit sets especially.

Consequently, these are unfinished pieces of metal - including ground drill blanks - that have undergone the initial stages of production but still require machining, shaping, and sharpening to become functional drill bits before they can be used.

These can then be utilised for many reasons and application from them being used for boring bars, cutting tools, dowel pins, pins for measuring between hole centers, and handles on custom tooling.

Drill and reamer blanks can also serve as gauges for checking hole sizes and drill bushing dimensions, and they don't need to be machined further in these applications.

Additionally, they function as guide pins for die sets and can be easily adapted into punches or cutting tools - in essence, they have many application uses.

Foundation Material

As a result, drill bit blanks form the foundation of various types of cutting tools, allowing manufacturers and machine shops to then be able customise their applications in industries such as construction, automotive, and precision engineering to give them a drill bit that is right for them.

So, whether you are working or looking for jobber length blanks or long series drills, drill bit blanks are really key for you to achieve your desired performance results.

Why Are Drill Bit Blanks Important in Manufacturing?

Drill bit blanks allow manufacturers to produce high-quality, standardised products very quickly.

By using blanks, you save time and reduce costs compared to starting from raw materials for each tool in many industries, such as:

Aerospace
Automotive
Construction
Defense
Electronics
Energy
Manufacturing
Medical Device
Metalworking
Woodworking

This is due to them needing to use strong drill bit blanks to ensure the consistency and reliability of their production runs.

HSS Drill Bit Blanks

For instance HSS blanks are particularly valuable for small hole drilling, as they offer you a lot of choice and options in drilling applications with materials like wood, plastic, and metals such as stainless steel for instance.

Types of Drill Bit Blanks

There are several types of drill bit blanks available, each suitable for different applications and materials.

For instance, the choice of drill blank sets you want to choose often depends on the type of material being drilled and the precision required, including options like letter size and jobber drill bit length for instance.

High-Speed Steel (HSS) Drill Bit Blanks

Drill Blank High-Speed Steel blanks, for example, are also a popular choice thanks to their toughness and heat resistance.

These can withstand high drilling speeds without losing their hardness, which makes them ideal for cutting through soft metals, wood, and plastic.

With options like the BLK - HSS blank, for example, really help to give you long-lasting and reliable finishes, for instance.

Carbide Drill Bit Blanks

Carbide drill bit blanks are then incredibly hard, as they can retain their sharpness longer than HSS blanks can.

Consequently, these are ideal for industrial applications involving harder materials like stainless steel, cast iron, and other tough metals.

These can also provide you with a bright finish and back taper that enhance their durability and precision further as well.

Cobalt Drill Bit Blanks

Cobalt drill bit blanks then feature enhanced heat resistance, which in turn makes them ideal for drilling hard metals like stainless steel and cast iron for example.

The added cobalt here increases their ability to withstand demanding conditions, which in turn provides you with a much superior level of performance in high-temperature applications like router bits and milling cutters for example.

Diamond-Coated Drill Bit Blanks

For extreme durability and hardness, diamond-coated drill bit blanks are used in applications requiring high precision, such as aerospace or electronics industries. These blanks are excellent for cutting through super-hard materials like glass, ceramics, and composites, particularly when precise reamer blanks or centre drills are needed.

Material Composition of Drill Bit Blanks

So, what can blank drill bits be made up of?

Steel Alloys in Drill Bit Blanks

Steel alloys, including HSS and cobalt-based alloys, are frequently used for drill bit blanks.

This is because these materials provide you with a good balance of toughness, heat resistance, and machinability - making them suitable for various applications, from use in small tools to more precision work and large die sets, for instance.

Tungsten Carbide in Drill Bit Blanks

Tungsten carbide is also one of the hardest materials used in drill bit blanks, as it offers you superior wear resistance and cutting ability on the whole.

All of these then make these blanks crucial for high-speed, high-precision drilling, especially in drilling applications involving abrasive materials.

How Are Drill Bit Blanks Manufactured?

The process of creating a drill bit blank involves several critical steps, ensuring that the final product is of the highest quality for further shaping and finishing.

For instance, this can consist of:

Step 1 - Raw Material Sourcing and Selection

Manufacturing first begins with sourcing high-quality raw materials like steel or tungsten carbide.

The composition of these materials is then crucial to ensuring that the blank can withstand the stresses of drilling and cutting down the line.

Step 2 - Forging and Shaping of Drill Bit Blanks

Once the materials are sourced, the next step is forging.

At this point, the metal is heated and shaped into cylindrical forms through forging or extrusion processes.

This gives the drill bit blank its basic shape before further machining.

Step 3 - Heat Treatment and Hardening

After the blank is shaped, it then undergoes heat treatment - a process that hardens the material by heating it to a high temperature and then rapidly cooling it.

This step is key for ensuring that the drill bit blank can endure the heat and friction generated during drilling and is suitable for use with varying hand tools and power tools accordingly.

Step 4 - Surface Finishing Techniques

The final step in blank bit manufacturing is then surface finishing, where the blank is ground and polished to remove any imperfections or burrs that are created in the process.

This stage also involves applying any coatings or treatments, such as titanium nitride, to improve the blank's durability and performance as well.

Choosing the Right Drill Bit Blank

Selecting the appropriate drill bit blank also depends on factors such as the material to be drilled, the required precision, and cost constraints.

So, whether you are using an S/S jobber drill, a bright jobber drill, or working with drill blanks 1/8, matching the blank to the specific task ensures that you get optimal performance from the bit as a result.
