What is a concrete drill bit called?
Drill bits that can drill through concrete are called masonry bits. They are also good for drilling through brick and stone. Drill bits with a tungsten carbide tip are the strongest; when it comes to solid concrete, the sharper the better. Masonry bits cut holes through concrete in two steps.
What is a HS drill bit?
High-speed steel (HSS) drill bits can drill wood, fiberglass, polyvinyl chloride (PVC) and soft metals such as aluminum. Cobalt drill bits are extremely hard and dissipate heat quickly. They’re mostly used for boring in aluminum and tough metals such as stainless steel.
What is a step drill bit?
A step drill bit can be used to drill a range of different sized holes with a single bit. Since each bit size drill holes less than 1/4″ deep, a step bit is mainly used for drilling thin material such as sheet metal.
What is a step drill bit used for?
What are titanium drill bits?
Titanium drill bits are HSS bits that have been coated with titanium nitride (TiN) using a process similar to electroplating. TiN is a ceramic material that increases the surface hardness of the bit and provides a thermal barrier by reducing friction.
What is twist drill bits?
Twist drill bits are used for drilling through anything from wood to plastic to metal products, but not masonry and concrete products. However, their primary use is for drilling through metal.

The correct tool to start a traditionally drilled hole (a hole drilled by a high-speed steel (HSS) twist drill bit) is a spotting drill bit (or a spot drill bit, as they are referenced in the U.S.).
What kind of drill bit do you use for rivets?
HSS Rivet Bits. Especially designed for drilling holes for rivets, these drill bits commonly have flutes on both ends, so you can get twice as many holes out of one drill bit. These bits are only designed for shallow holes through thin metal, where the hole is no deeper than 1.25 x ‘the diameter of the hole’.
What does it mean to drill the right hole?
Choosing the right way not only means that you get the right hole in the right place, but that you get it with the least amount of trouble and without damaging the material, your tools, or yourself. Just about anything can be drilled, but what you’re drilling is the biggest question when picking a bit.
What do you need to know before drilling a hole?
Before you start drilling be sure to fully tighten the bit in the drill chuck and make sure it’s straight or you’ll quickly break the bit. The quickest way to check if it’s straight is to run the drill without drilling a hole.
