DeWALT DT71563-QZ Combination Drill Bit Set - 100 Pieces - Black Durable Case Included

Product Information

A drill bit's suitability for drilling into certain materials usually depends on what the drill bit is made from and coated with. The drill bit guide below describes the main options: The best drill bits for metal, and particularly for carbon steels, goes to Milwaukee for their excellent cobalt bits. Just like their titanium bits, they have the Red Helix variable flute design. They also have a 135° QuadEdge Tip that helps it drill much faster than other cobalt bits we tested and still keep the walking to a minimum. Auger bits closely mirror spade bits but work better for deeper holes that require lots of chip removal at the point of entry. The full-fluted design makes this possible. You typically need a stronger drill when using these bits. This becomes very apparent when drilling deep holes or holes that exceed 3/4-inches in diameter.

Most red wall plugs are 6mm in diameter, so to drill a hole for a red plug, you will need a 6mm drill bit. They’re great for moving beyond your standard twist bit sizes and eliminating the need for a punch for holes up to 1-1/4″ or a little more. They also feature a flat flute with a slight taper at each step. This gives you the ability to drill in sheet metal and other thin metals that might deform if you cut through at an angle. In addition to making new holes, they also excel at enlarging existing ones. Carbide-tipped: one of the hardest materials on the planet, this drill bit only uses carbide on the tip. It’s suitable for drilling masonry, tiles and concrete. Milwaukee updated these bits with Enhanced Tapered Web. This new core design strengthens it with better flute durability.

White wall plugs can vary in diameter (6-10mm). So, to drill a hole for a white wall plug, you will need a drill bit that’s the same diameter as the plug you choose. Most brown wall plugs are 7mm in diameter, so to drill a hole for a brown plug, you will need a 7mm drill bit.

We consult with innovators in the technology and design of tools to gain a broader grasp of where these products fit and how they work.

SDS plus shank - This is another type of slotted drive system. It’s used for most masonry drill bits. Solid carbide: a drill bit as described above, but it’s made entirely from carbide. It’s suitable for drilling into tough materials.

One of the most cost-effective is a spade bit. Sometimes called a paddle bit thanks to its shape, spade bits throw chips out as they cut rather than sending it up through the flutes. It makes for a much cooler slow-motion video but generally leaves a larger mess. Unlike your standard twist bits, spade bits are really only good for making holes in wood. Auger BitsHex shank - A hexagonal-shaped shank used in screw guns or electric screwdrivers with a hammer mode. Cobalt: an incredibly strong alloy metal used to drill through tough materials. It can withstand heat and resistance and is the best drill bit for stainless steel. Twist bits work best for drilling in a myriad of materials when the target is a hole diameter of 1/2-inch or less. As you move beyond a 1/2″ hole diameter, you move away from traditional twist bits into some different options. Spade Bits

A drill bit is a cutting tool that’s fitted into a power drill and used to cut holes in materials. They come in a wide variety of shapes and sizes, but they all have similar parts as follows: We know we didn’t cover every category of hole-making accessories like hole saws and didn’t touch driver bits, either. While we chose to draw the line where we did, keep your eyes open for more buying guides to cover those accessories down the road! Disagree With Our Choices?
