Today most industrial applications use drills and drill bits. Woodworking, construction, materials like plastic and metals, and special applications for crafts such as gemology and medical surgery. A collection of drill bits is included in drill bit sets, which normally come in a variety of sizes to ensure suitability for various applications. The right bit must be used while drilling any material in order to easily and quickly make holes. If you are new to this, here in this article, we’ll explain the difference between each size and how to choose the right drill bit for your application on various materials, including metal, masonry, plastics, wood, glass, and tiles.
Types of Drill Bits
Depending on the type of material to be drilled and the size of the hole needed, drill bits are available in a variety of forms and sizes. Below we’ve listed some of the most common types of drill bits;
● Drill Bit for Metals or Steel
The best drill bit types for metals include HSS, Titanium coated or cobalt steel, Metal hole saws, and Unibit (step bits). Iron, steel, and other metals like brass, copper, and alloys of aluminum can all be drilled using HSS bits.
● Best Drill Bits For Concrete
One of the most challenging tasks in construction is drilling concrete. A drill bit that can withstand wear, heat, and maintain speed is necessary for drilling into rebar. Hollow drill bits or Hollow concrete drill bits (SDS Plus and SDS Max) Filter are designed for almost dust-free drilling in concrete and reinforced concrete. SDS bits are a great option if you’re looking for extremely strong bits that work well with concrete and other tough materials.
● Best Drill Bits For Wood
The best drill bits for wood are spade or flat wood bits, Lip and spur (Brad Point) bits, Hole saws, Masonry bits, Step bits, and HSS bits if nothing else is available.
● Best Drill Bit for Plastic
The same pieces that are used for wood can be used. But drill slowly. Friction can quickly cause the plastic to melt if you drill quickly.
Drill Bit Sizes
There are four standard-size units in which drill bits can be offered. These include letter size, metric, wire gauge, and English or fractional. The base units for an English drill bit are inches or fractions of inches. Metric base units like millimeters and centimeters are used in the construction of metric drill bits. Standard wire gauge sizes 1 through 80 are used to define a wire gauge drill bit. Standard letter designation sizes from A to Z are used to designate a letter size drill bit. When selecting drill bits, the complete tool-cutting diameter is a crucial parameter.
Drill Bit Uses
Drill bits are commonly used to create circular holes in materials such as metal, masonry, wood, and drywall. They could make a hole for a fastener or anchor, or a path for wiring. Both single bits and multi-sized sets of bits, known as drill indexes, are available for purchase. Also, consider the material you’re drilling into, the drill bit’s physical shape, and its composition when choosing a drill bit.
The drill bits are produced in a variety of sizes and forms. It is preferable to select a drill bit that perfectly fits your requirements. There are a variety of types of drill bits available, so make sure you will always have to choose the type that you need.
