9+ Best Drill Bits | Unrivaled Guide 2022

Types Of Drill Bits

• Flat Tip Drill: This fluted bit is designed for use on wood. It features a sharp spur on the tip and spiral grooves (grooves) on both sides. The sharp trick helps to position the piece in the ideal place and the grooves are meant to catch the wood chips and deflect them out of the hole as it pierces, causing a new hole. Brad-point pieces make quick work of tasks that require a high amount of detail.
• Twist Bit: This regular piece also has a pointed cutting tip, like the brad point piece, it features fluted sides to eliminate waste because the hole has been drilled. The spin piece is a generic piece for home use and can be used on wood, thin metal, and vinyl.
• Tip for countersink : considered a special piece, the piece for countersink has been realized to create a pilot hole by using a larger opening on the top for countersinking the screw heads. Used primarily on wood, the countersink drill bit allows you to insert the fastener deep enough so that the mind does not float above the surface of the material.
• Forstner Tip: For use on wood, the Forstner tip, named in honor of its 19th century inventor, Benjamin Forstner, features the same tip spur as a brad point piece for precise drilling, but drill a flat bottom hole . Forstner bits are used to make holes to hold anchors (not screws) and are usually found in furniture and luxury furniture construction.
• Fork Drill Bit : Also referred to as a drill bit, a drill bit includes a top layer of the bit for precision along with a horizontal blade made to cut large holes up to 4cm round. Forked bits are generally used to drill holes through wooden pins to run cables and water supply lines.
• Hole Saw Bit : Used for making huge holes in wood, thin vinyl, ceramic tile and other sheet metal products, hole saw pieces normally come in two drills – the small one itself, a sharp-toothed cylinder shaped of saw and a mandrel (shaft) that attaches to the workpiece and fits into the drill.
• Measure the drill bit: This pyramid-shaped piece is widely used for expanding current holes and can be used with scattered materials usually sheet metal, but can also be used on vinyl sheets. The manufacturer frequently labels each step on the part with the correspondingly sized distance it moves. A stepped drill bit can also assume the position of a countersunk bit by extending the surface of a hole just enough to recess the head of the fastener.

Material Topics

While most drill bits are made from metal, some types of metal are far better than other people for drilling holes in various types of material.

• The carbon steel parts are developed for drilling into wood; they should not be used for drilling as they have a tendency to heat up too quickly and could break.
• High Speed ​​Steel (HSS) drill bits are created by combining metallic metals with tungsten or molybdenum to create a drill that withstands higher temperatures than carbon steel parts. HHS pieces are acceptable for use on wood, soft metals and fiberglass.
• HHS titanium pieces feature a thin titanium coating that reduces friction and allows tips to stay sharper, for longer. Titanium-coated HHS can be used on ceramics, wood, hard plastics, and soft metals, such as aluminum and lead.
• HHS black oxide pieces feature a thin chrome coating that helps reduce rust and corrosion, making them a fantastic option for use in humid or wet conditions. They are acceptable for use with most surfaces, such as wood, thin alloys (e.g. aluminum foil) and fiberglass.
• Cobalt Drill Bits are made by mixing steel metal with cobalt to make a super strong drill bit. Cobalt pieces are made for drilling into metals, such as aluminum and stainless steel.
• Tungsten carbide drills are more expensive than HHS pieces and are used almost exclusively for drilling ceramic tiles and masonry, although the fragility of the pieces makes them more vulnerable to breakage.
