Considerations to Buy the Best Drill Bits for Stainless Steel

Here are features you need to take into account in order to find your ideal pick.



The design of the drill bit is an important aspect that must be kept in mind before the purchase. It is one of the determining factors which assures a clean and smooth cut. There are numerous styles and designs such as twist style, brad-point style, auger drill bits, Forstner drill bits, etc available in the market.

Each design comes with a unique perk and, you need to distinguish which type and style of drill bit you require for the work in hand.


In the present day, technology has advanced to such an extent that we are capable of using various materials and heavy-alloys to enhance the performance and durability of drill bits. Drill bits are made of Cobalt, Titanium, Gold oxides, HSS (High-Speed Steel), Carbide, and numerous other ingredients.

But the best amongst all these are Titanium and Cobalt. These assure superior durability and performance. And, can penetrate through any hard surface, including the soft ones. 

Drill Bit Angle

All drill bits have a certain angle (usually 118 or 135-degrees). These enable steady and uniform drilling and most of them have an auto-centering mechanism. The mechanism prevents walking and promises straight drilling. Recently, the hex (360-degrees) bit is also becoming famous. 

So before buying, be 100% sure that you are buying a one which you require.


Resistance to what? Well, drill bits undergo some heavy-duty punishment! So, every drill bit has to be resistant to heat. During the drill, the bits tend to heat up quickly, and hot metal is more prone to damage. Thus, it is necessary that the bits can withstand extreme temperature and still show remarkable results.

Another resistive feature that drill bits must-have is resistance to corrosion or wear. Drill bits need to be built with outstanding pressure resistance so that they don’t falter when working on harder materials.

Lastly, it is not unnatural for the metal drill bits to come in contact with water! And, the presence of water put the bits at extreme risk of catching rust. Thus, it is mandatory that the drills have to be rustproof, wear and tear-resistant, as well as corrosion-resistant.


Drill bits come in numerous sizes starting from 1/4-inches to 1-inch. Thus, letting you make various cuts of different sizes and, that too, with exceptional precision of different sizes and, that too, with exceptional precision. 

Also, the drill bit has to be of a specific dimension. Therefore, it cannot be too sizable and can’t be too minuscule. The minuscule size will attribute to weak structure and will the bits untraceable in your wide arsenal of tools.


Another feature that you have to keep in mind is the shank of the structure. The shanks are what you attach your drilling devices to and, the drill bit’s shank and your drilling machine must be compatible. 

So, the most preferred are the straight shanks with a chamfered end. They firmly grip your drilling machines and ensures that they won’t fly away while drilling. There are numerous shank types like round shanks, SDS shanks, tri-flat shanks, hex shanks, etc. Hence, be sure that you are buying the right type of shanks.

Tip Design

The tip design of the bits are essential as well! And, in the recent market, there are numerous tip designs which include the L-type double fluter (standard tips), U-type double fluter (rust remover), four-flute (superior balance, etc. These designs determine the fluidity and how smoothly the bits cut through materials.

Plus, each of these flutes has their own unique attributes and, it is entirely dependant on you and the type of work you are doing to pick the right tip design. 

Also, you have to keep in mind about the spurs and cutting-edges of the drill bits. For instance, a flat spur is better for decorations, whereas a pointed spur assures superior precision and cutting speed. Furthermore, the cutting-lips need to be sharp and well-maintained because with that you won’t have a uniform cut.

Thus, you must go for a drill bit, that ticks all these. So, before buying a drill bit, it is necessary to understand the requirements for the work and buying bits with adequate tips.
