Product Information

A HSS drill bit is made from high-speed steel, as described in the materials section above. It’s often used in multi-purpose drill bits as it can be used on wood, plastic and metal. HSS drill bits are also the best drill bits for soft metals. Milwaukee updated these bits with Enhanced Tapered Web. This new core design strengthens it with better flute durability.

Flutes: a spiral channel that runs from the cutting lip to the shank. It helps to remove the material as it’s cut from the hole.

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. 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: SDS-Plus and SDS-Max rotary hammers do best for drilling on concrete and masonry materials. Hammer drills, however, more than suffice for drilling smaller diameter holes. When you start looking for the best concrete drill bits and the best masonry drill bits, the need for handling multiple materials arises. For that, our Pros consistently turn to Bosch Daredevil Multi-Purpose Drill Bits. Most brown wall plugs are 7mm in diameter, so to drill a hole for a brown plug, you will need a 7mm drill bit.

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: Tungsten carbide: made from a mix of tungsten metal and carbon. It's even more hard-wearing than the standard carbide above. It is suitable for drilling into extremely tough materials such as masonry. 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 Bits Grey wall plugs can vary in diameter (6-14mm). So, to drill a hole for a grey wall plug, you will need a drill bit that’s the same diameter as the plug you choose.High-speed steel: made from carbon steel with chromium and vanadium additives. It’s suitable for drilling wood, plastic and soft metals. We know we didn’t cover every category of hole-making accessories like hole saws and didn’t touch driver bits, either.
