Rotary Hammer Bits: Choosing the Right Bit for Concrete Drilling


Rotary Hammer Bits are used in drilling concrete and other heavy duty construction projects. They have been around since the early 1900’s. Today, they are widely used in various industries such as mining, oil & gas exploration, road building, etc. Rotary hammers were invented by John Deere Company in 1879 and manufactured by them until 1986 when it was sold to a Japanese company called Kawada Industries Ltd.. These days, these tools are mainly used in the oil industry. Rotary hammers are usually made from cast iron or steel with a hardened steel head. Steel is considered stronger than cast iron because it cannot rust like iron does. However, both materials can be brittle if not properly cared for. For example, the metal may crack under pressure and cause damage to the tool or even break off completely during use. A typical rotary hammer weighs between 1 and 2 pounds (0.5 – 0.9 kg). The heads of these tools are made from hardened steel, but they can also be made out of other metals such as aluminum, brass, bronze or even plastic. Rotary hammers come in different sizes ranging from 3/4″ to 5″. Most rotary hammers have a handle attached at one end. Some models have two handles while others do not. There are many brands of rotary hammer available today including Stanley, Makita and Husky Tools among others.

Rotary hammer bits, also known as masonry bits and rock bits are tools used in drilling holes in masonry and concrete. Rotary hammer bits are typically made from steel or tungsten carbide. Tungsten carbide is a very hard material and can withstand extreme pressure. Rotary hammer bits are similar to wood boring bits, but they have a fluted tip that can help it carry the drill dust out of the hole.
