Twist Drill Bit Manufacturers – The Comprehensive FAQ Guide

Nowadays, choosing the manufacturing company for your twist drill bits is a challenge.

Apart from the fact that there are already a lot, the prices are becoming more competitive. If you’re looking for the best twist drill bit manufacturer, you’re in the right post.

Today, we’ll be discussing twist drill bits and their manufacturers in an in-depth fashion; that, by the end of the guide, you’ll know where to go and who to trust!

The Different Point Angles of  Twist Drill Bits

Different manufacturers create varying angle degrees of twist drill bits.

The different angles mean different types of application – and they include:

• 118 degrees
• 130 degrees
• 135 degrees

You’d want to use a 118-degree twist drill bit if you want aggressive cuts. More so, this is what you’ll need if you are to work on soft materials like wood and paper. It can cut through steel, but it will dull quickly because of the steepness of the degree.

The 130-degree point angle is what you want if you’re looking to cut through semi-hard materials such as plastic, ceramics, etc. It’s made for harder materials than wood, but not as hard as steel.

Lastly, the 135-degree twist drill bit point angle is what you need to cut through or penetrate steel.

Color-Coding of Different Twist Drill Manufacturer

Many twist drill bit manufacturers assign colors to the different classifications of twist drill bits.

But, it is important to note that the different color-coding of twist drill bits do not dictate the quality or the performance they give.

Generally, HSS twist drill bits, that are often fully ground, are white in color. Nitrided drill bits or black oxide drill bits are coated with a chemical composition, developing the strength and the overall durability of it.

Cobalt drill bits usually appear in a dull golden color – almost yellowish brown.

While there are a lot of colors to choose from, they often do not have any bearing on the performance and the quality of the drill bit.

Can You Cut Steel With Twist Drill Bits?

Yes! As mentioned above, a 135-degree point angle twist drill bit is perfect for cutting hardened materials – which includes steel, among others.

The twist drill bit is used to cut through a thick portion of the steel

Many twist drill bit suppliers make varying angles to be able to provide a vast array of clients. So, you wouldn’t have to worry about where to find varying angles of twist drill bits.

Can You Sharpen Titanium Twist Drill Bits?

Akin to other types of drill bits, you can sharpen and re-sharpen titanium twist drill bits.

However, it’s not the most ideal to do so. In fact, doing so runs the risk of your titanium drill bit to lose its coating, which also translates to losing heat resistance and strength.

Different Processes on How Twist Drill Bits are Made?

Twist drill bit manufacturers perform different procedures and manufacturing techniques in producing twist drill bits.

The process they’ll use will depend on the kind of drill bit you want, the material used, and the results sought after by their clients.

Twist drill bits are manufactured via the following processes:

Roll Forged

Also called hot forge rolling, it’s a manufacturing process where the raw material is fed through two (2) distinctive-shaped rollers, creating the twist drill bit.

In roll forging, the material worked on is heated up to a certain temperature.

Milled

The process of milling, on the other hand, utilizes a rotary cutter, removing bits and parts of materials, creating the drill bit.

Fully Ground

Lastly, grinding can also be a procedure to create twist drill bits.

It uses a grinding disc as the cutting tool, creating specific angles and grooves on a workpiece.

Those are the three (3) primary procedures used by twist drill bit suppliers in creating and producing twist drill bits.

What is a Tapered Shank Twist Drill Manufacturers?

It’s a type of tool – drill bit – that is specifically made to match a tapered holder.

Its main use is to be able to fit holders that are tapered.

Unlike regular shanks that run straight, a tapered shank would help you in fitting it even in narrow and shallow holes.

How Does a Twist Drill Bit Function?

Twist drill bits are rotating cutters that have two (2) flutes and two (2) cutting edges.

A bit, when inserted into a drill, is used for material removal

The flutes are formed within the body, providing the cutting lips and permitting chip removal.

Using a power drill, the bit rotates and removes material. The rotating motion allows the bit to remove and cut parts of the material.

What Materials Are Used to Manufacture Twist Drill Bits?

Creating twist drill bits isn’t just limited to a single material.

As a matter of fact, manufacturers use a wide array of steel types to create and manufacture twist drill bits.

They use carbon steels and/or high-speed steels or (HSS). When it comes to the coating, there’s cobalt, zirconium, carbide tipped, titanium, and many more!

The quality of the bit will depend not only on the material; the procedure also has an effect on the final result it.

Parts and Anatomy of a Drill Bit

What is Web Thinning in Manufacture Twist Drill?

To understand web thinning, it’s imperative to know what the “web” in a drill is.

Basically, the web is the center part of the drill’s body; it’s what connects the lands to the body. Therefore, web thinning is the process or the procedure of reducing the center part of the drill.

You do web thinning to decrease the cutting resistance just at the edge of the chisel.

Different Results You Can Get With Web Thinning

As we know, you can decrease the thickness of a twist drill bit’s web.

Moreover, you can actually achieve four (4) different results if you perform web thinning.

Depending on what you’re looking for, you can perform:

• Type C Thinning (Split Point)
• Type B Thinning (Form B)
• Type R Thinning (Helical Thinning)
• Type A Thinning (Form A)

Type C Thinning is the most ideal if you’re going to be working on tough and hardened materials because of the split point.

Type B Thinning is perfect if you plan on working with materials that have low levels of cutting resistance. Furthermore, you’d want to perform Type B Thinning to avoid chipping of the cutting lips.

Type R Thinning or helical thinning would help you make sure that there’ll be chip breaking and removal frequently. Because of the different directions of cutting edges, it’ll easily help you with centering.

Last but most definitely not least is Form A or Type A Thinning. It’s considered the narrowest web in its final form. More so, it also offered wide fluted drills which ensure smooth and easy chip removal.

Titanium Twist Drill Bits vs. Cobalt Drill Bits: Which is Better?

From their composition alone, you already know how different they are.

To start off, they differ in terms of the principal material used to manufacture them. Titanium drill bits are usually made of steel. Cobalt drill bits are made from a combination of a kind of steel alloy and cobalt.

Titanium drill bits are coated with titanium carbonitride or titanium nitride; while cobalt bits are just coated with what they’re made from.

In terms of the material they’re capable of working on, cobalt drill bits work with harder and tougher materials better. Titanium drill bits, on the other hand, work perfectly with soft materials such as wood, plastics, soft metals, etc.

Unlike cobalt drill bits, titanium drill bits aren’t made from titanium as their core is steel – it’s just dubbed and called titanium drill bits because they’re coated with titanium.
