Hex shank bits are one of the most commonly used bits in various projects. You can see the multipurpose use of this type of drill bit in metalworking, woodworking, machine working, construction, tool fabrication, and utility works.

A hexagonal drill bit shank has the shape of a hexagon. After all, it has got its name from the particular form it holds.

Now it’s time for you to choose among the hex shank drill bits given below with a short product description. Also, there’s a buyer’s guide and FAQs to help you make the decision easier.

Things to Consider When Choosing Hex Shank Drill Bits

You must consider some facts while buying the best Hex Shank Drill Bits. It’ll help you to get the right drilling bits for your work. So, keep the following factors in mind when you pick your bits from the bunch. 

What Are the Drill Bits Made of?

There are three basic materials that the drill bits are made of, those are-

Titanium (Coating)

It is the ideal choice for metal and wood-drilling. A coat of titanium nitride covers the outer portion of the bits to resist friction and corrosion. It results in a hardened surface that reduces heat buildup creating a thermal barrier. 

These drill bits are slightly costly. But they drill faster than the black oxide drill bits. Also, they last longer than them.

One of the downsides is that you could lose the benefits of titanium nitride. Because it is just a coating, and the coating can diminish as time passes.

Black Oxide (Coating)

A black oxide coating over the bits’ steel resists corrosion and reduces friction between the bit and workpiece. You can use the comparatively inexpensive black oxide bits for wood, softer metal, plastics, and composites.

The drawbacks are that they don’t stay sharp as long as some of the other twist bit options out there, and you lose the benefits as the coating fades from the cutting edges. Another thing to remember is that they only can cut through softer steels under 1/8-inch in thickness.

Cobalt (Steel Blend)

Cobalt bits are best for metal drilling. Though, they are capable of drilling through about everything.

These bits are made from an alloy of steel and 5% – 8% of cobalt. Cobalt drill bits don’t wear away like a coating. So, you can sharpen them as you need instead of throwing them away. Though these are a bit costly, they are the best pick to drill through cast iron.

Hex Shafts

A few drills are made with a ¼-inch hex head fitting instead of the conventional barrel-shaped drill knife. This is a remarkable extension because it implies that your pieces will fit an impact driver as well as your drill. 

Similarly, these pieces tend to slip less than standard tube-shaped heads.

Set the Size

Especially for individual users, in addition to the jack of all trades, having a wide range of drill types and sizes would be a great advantage. We’ve featured a few arrangements of this kind in the surveys above.

Especially in settings where high precision is required, this is a component in a small amount. These types of buyers will search for high-precision bores and will be less concerned about the wide assortment of types and sizes.

Does the Drill Bit Match to the Hole Size?

You’ll get a variety of sizes and in different measurements. So, it’s better to look beforehand about what you exactly need. You’ll find the drilling bits in the following design on the market.

Twist Bits: It’s best for drilling those materials that require a hole that is less than 1/2″ in diameter.

Spade Bits

Also known as paddle bits. It is one of the most cost-effective bits on the market. The particular shape of this bit throws chips out while they cut but creates a messy surrounding. They are good for making holes in wood.

Auger Bits

Auger bits are similar to spade bits but work much better than them.

Step Bits

This design is best for metalwork. It’s also known as unibits. These bits are best for thin metals.
