Drill bits are designed to drill holes in a variety of different common materials. These include different types of wood, metal, plastic, ceramic tile, porcelain, and concrete. Drill bits made for steel, aluminum, copper, cast iron, sheet metal, fiberglass, brick, vinyl flooring, and more are also available.
Sized for their diameter, drill bits are constructed in a range of styles to help with specific tasks. Not sure which drill bit you need or what you need in your toolbox? Keep reading for a rundown of the different types of drill bits you're likely to come across.
When it comes to drills, there are two easily identifiable parts you need to know about - the shank and the chuck. Here's a little information to help you understand more about how drills and drill bits work:
Drill Bit Construction
The shank is the end of the drill bit that fits into the drill and is secured by the chuck. A round shank helps to center a bit in the chuck more accurately. The flat surfaces on a hex shank allow the chuck to grip the drill bit more securely.
Quarter-inch hex shank bits are intended to be used on 1/4-inch impact drivers and can be quickly changed. SDS (slotted drive system) shanks are used for concrete drills and demolition bits and work specifically with SDS-Plus and SDS-Max rotary hammer drills.
The chuck is the part of the drill that attaches the drill bit. Most power drills for home use have a 3/8-inch or 1/2-inch chuck. Larger chucks come in 5/8-inch and 3/4-inch sizes but are usually fitted on heavy-duty and industrial power drills and drill presses.
Twist Drill Bit
1. Twist drill bits can be used on light metal, wood, plastic, metal, ceramic, and masonry.
2. Useful for home repairs, maintenance, and building projects with metal, wood, or ceramics.
3. General-purpose rotary drilling; most common drill bits for home use.
