Drill bits come in a wide variety of shapes and sizes and are made in various materials and coatings made to suit specific projects, such as high-speed steel (HSS) which is a more economical choice made for boring into soft steels, wood, and plastic.

Cobalt (HsCO) is an upgrade that includes a 5-8% cobalt blend with the base material, ideal for drilling into stainless steel and harder steel, and Carbide (Carb), the hardest bit, used mainly for production and should not be used in hand drills or in a professional drill press for the most accurate cylindrical hole. This review covers the top ten drill bits for everyday use, based on quality and durability.

Buyers Guide Questions

How to use Drill Bits?

Drill bits are tools that are used with a drill to create holes in various materials, such as metal, plastic, or wood. These come in many shapes and sizes, depending on the type of project and what material is being drilled. To use a bit, insert the bit shank, the end that’s opposite of the cutting end, into your chuck–which is the cylinder-like clamp. Turn the clamp to tighten the bit into the chuck, and make sure the bit is tight and secure before drilling.

All bits are designed to spin clockwise to drill, and counter-clockwise to reverse, so make sure your drill is going in the right direction. Allow the tool to do most of the work while you continue to apply steady pressure that is directly parallel to the bit. the bit should stay straight as it spins and not wobble.

What are brad Point Drill bits used For?

Not everyone knows this – but brad-point bits are made specifically for drilling into wood. These are special with a pointed end that is self-centering, allowing the bit to make the initial hole and bite right into the wood, rather than skitting all around the surface like others would do. If you are looking for something to saw Wood instead, please head over to our guide here.

This pointed end, or brad point, acts like an awl and helps improve the accuracy of the drill, placing the bit exactly where you need it to be. There are also a set of cutting spurs on either side of the point which will slice the wood fibers upon contact, allowing for a smoother, cleaner hole.

How to Drill a hole in a Metal Door?

First, you would need to pencil in where you want the hole to be. Then, with a hammer (if you are looking for a drill to do the work for you, we’ve got the best hammer for drilling with less effort reviewed here), use a center punch, or a nail, to tap a small indentation at the mark. This step is important, because if you do not tap a center mark, your drill will skate right across the surface and leave a mark. Then, insert the correct twist drill bit and drive into the hole, applying some pressure as you drill, staying in line with the bit.

What Are Black Oxide Drill Bits Used For?

These are HSS bits that are heated up to 950 degrees Fahrenheit that creates a black oxide finish, resisting rust and corrosion, and reduces friction that helps speed up drilling. They are well suited for steel, copper, aluminum, brass, oak, maple, pine, PVC, polycarbonate, acrylic, nylon and composites.

What are the best Drill bits for Drilling Steel?

HSS (High-speed steel) bits work well for drilling into soft steels. Cobalt (HSCO) bits are an upgrade from HSS with 5-8% colbalt blended into the base material, making these suitable for boring into harder steels. Carbide (Carb) bits are the hardest of all, and are primarily used in production with higher equipment, not to be used in hand drills or presses.

Best Quality Drill bits for Stainless Steel?

Cobalt bits with a 5-8% cobalt blend are the most durable and suitable for all your stainless steel projects. We recommend the DEWALT DW1361 Titanium Pilot Point Drill Bit Set or the Irwin Tools 3018002 Cobalt Metal Drill Bit Set. You’d do well to match this up for a saw specifically used for cutting stainless steel.

Are Drill bits Interchangeable?

Most all drills and standard drill bits are interchangeable, so as long as your drill has a chuck size that will fit your drill bit, you should be fine.
