Buying Guide: Best Drill Bits for Stainless Steel
You should consider below factors before buying drill bits for hardened steel.
Materials for Drill Bits
The life and performance of a drill bit completely depends on the materials used to make them and the coatings used on them. There are a choice of different materials and coatings available. Drill bits with a titanium coating or drill bits with cobalt are some of the best drill bit for stainless steel.
Scroll down for a discussion of some of the common materials used in drill bits.
Low Carbon Steel: These kinds of bits are softer, as compared to bits made of other materials. They often require sharpening. The low carbon steel bits work well for piercing through materials like soft plastics or wood. If you are looking for the best drill bit for drilling stainless steel, you wouldn’t choose a bit made of low carbon steel.
High Carbon Steel: This is sometimes called hardened steel. High carbon steel tends to be more brittle than other kinds of metal. The shape of the drill bits can be distorted when the bits are overheated. They are mostly used for boring into wood or steel.
High-Speed Steel (HSS): This material is used for bits that drill both harder and softer surfaces. They defy heat and stay sharp for a longer amount of time. Besides, they work great to penetrate wood, fiberglass, PVC (polyvinyl chloride), and aluminum. These special kinds of steels stay hard at temperatures up to 932 degrees F (500degrees C) and are very resistant to wear. High-speed steels are alloys made of chromium, tungsten, molybdenum and vanadium.
Cobalt: Cobalt is tremendously hard and is excellent for cutting tough surfaces. Drill bits made with cobalt are often stamped to show the percentage of cobalt in the bit, which also indicates how strong the bit I likely to be. Cobalt resists heat and performs well on the toughest surfaces. Additionally, drill bits with cobalt are favored by professionals as they are popular for their longer life and high-performance. If you’re wondering what kind of drill bit you need for stainless steel, a bit with cobalt is an excellent choice.
Other bits you can use to drill stainless steel include the following:
Black oxide-coated HSS: These materials have a finish on them that helps them to resist weathering and increases the life of the bit. Black oxide-coated HSS drill bits are more durable than many other materials. They work great when you need to cut holes in steel, hardwood, softwood, PVC, and fiberglass.
Titanium-coated HSS: These bits tend to produce less friction and offer high-performance drilling. They are sturdy and very sharp for drilling any kind of surface. They are basically used for boring wood, steel, fiberglass, and PVC. This kind of bit performs well in matrix drills.
Carbide-tipped: These kinds of bits stay sharper than most other materials. They work great for piercing surfaces like tile and masonry. They are one of the best kinds of drill bit for stainless steel and metal as well.
Different shapes are used for drilling different surfaces. You can’t use just any shape of bit to drill any kind of material. To get the top quality drill bits for stainless steel you need a drill bit with the right shape for the material you will be drilling.
Twist Bit: This is one of the most common shapes of drill bits. Twist bits are usually used for boring hardened steel surfaces, including stainless steel. But if you want this, you can use them on other kinds of materials as well. They are perfect for drilling in wood, plastic and light steel.
Split Point Bit: Like the twist bit, this shape is also for drilling steel. It features a split point, unlike twist bit, and this allows the bit to be self-centering even when boring through the toughest surfaces. Its various points and angles are sharper than many other kids of bits so it can cut precisely through surfaces.
Brad Point Bit: This bit is one of the most favorite bits used by woodworkers. It has a sharp tip that positions the bit precisely for an accurate hole and maintains the center while drilling. Its flute-groove is another great feature that wraps around the bit and gets rid of the wood chips.
Countersink Bit: You can also call it a screw pilot bit. This bit bore pilot, countersink and counter-bore holes. It helps to countersink a snap and set up a plug over the snap head. This shape of bit works well for drilling through wood surfaces.
Auger Bits: These bits are longer in shape, so they penetrate through long surfaces and produce rough holes. The long spirals help to pierce the material and remove the shavings. Auger bits have a screw tip that starts the hole and pulls the bit through the surface get a clean hole. They pierce quickly through wood, such as wooden framing studs.
Spade or Paddle Bits: Yes, the name describes the shape of the bit. If you’ve seen a garden spade, you know what these bits look like. They are used to pierce large-diameter holes in wood. These bits have flattened blade and a sharp point that helps to position and steady the bit.
Hole Saw Bits: Use hold saw bits to drill larger holes. They have two parts: a twist bit and a circular saw ring with serrated teeth. They produce smooth holes and are mainly used to drill holes in tile and masonry.
Step Bit: These are smaller bits that are used to drill up to 1/4-inch diameter. The step bit works great on wood. Its stepped design lets you use a single bit to bore holes of different diameters. You can use this bit to produce clean holes. The bit removes shavings or debris from the hole.
Masonry Bit: This type of bit pierces through stubborn, hard surfaces including concrete, brick, stone, glass bricks, and other masonry materials. You can use them in corded or cordless rotary drills to penetrate the masonry precisely. Masonry bits feature a carbide tip that helps to drive the bit into the material. Some masonry bits are deeply fluted to clean out the dust and dirt from drilling into concrete. Another kind of fluted bit called a “fast spiral” shape is usually used for drilling into brick.
Compatibility With Your Drill Machine
Most drill bits, regardless of the material they are made from, their shape and size, will fit into your drill comfortably. However, there may be times when the shank of the drill bit is too big to fit into your drill’s chuck.
We therefore always advise you to check the specifications of your drill before choosing any drill bit at all. Make sure that the thickness or diameter of the bit’s shank will fits perfectly into the drill’s chuck. We cannot even begin to stress how important this! However, there are a few bits available that are made with a smaller diameter shank than normal so you can use them in a smaller drill.
Here are a few common types of shanks you should know about:
- Round shanks fit instantly into the chuck and will be perfectly centered.
- Hex shank, or hexagonal shape shank, has six flat surfaces. This style of shank sits tightly in the chuck, which reduces the amount of wobble and walking of the bit.
- SDS shank, or a Slot Driven System shanks, sits on the spring-loaded chuck of a hammer drill and doesn’t need any manual adjustments.
What is the Best Kind of Bit for Drilling Stainless Steel?
There are different types of drill bits available in the market. What is the best kind of drill bit for drilling stainless steel? There are choices, and in the end, it depends on what you prefer. But there are two main kinds of bit you should consider, cobalt and the titanium bits. It also helps a lot if you have a powerful drill. But no matter how powerful the drill is, you need a bit that is designed to drill tough surfaces like stainless steel. Lets take a look at both cobalt and titanium bits.
The benefits you can get from Cobalt bits are: Cobalt drill bits are coated with—you guessed it–cobalt. It makes the drill bit hard enough to penetrate through tough metals such as stainless steel. Another benefit of cobalt is that it helps the drill bit to resist the heat caused by drilling. Also, cobalt bits stay sharp for a long time.
The benefits you can get from Titanium bits are: Titanium drill bits are manufactured from titanium applied over high-speed steel. They are sturdy and durable enough to pierce through the hardest materials. These bits are also very strong and powerful drill bits, like the cobalt bits. The titanium coating also helps the drill bit to resist heat, and drill bits cause a lot of heat when they drill into stainless steel. However, titanium bits are also suitable for use on wood and plastic, in addition to steel. Titanium bits tend to hold their sharpness for a long time, and these bits are harder and more durable harder than other materials like high-speed steel alone, or carbon-tipped drill bits.
