Product Information

Auger bits have a threaded tip that pulls the bit forward as it rotates in the wood. Its strong, full-fluted design also makes it easier to drill nice and straight. Step Bits

Hex shank - A hexagonal-shaped shank used in screw guns or electric screwdrivers with a hammer mode.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. 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?

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. Each year, we bring in and review more than 250 individual products. Our team will put our hands on hundreds of additional tools at media events and trade shows throughout the year. TiAIM: a titanium aluminium nitrate coating that increases resistance to abrasion and heat on drill bits designed to cut metal. 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.

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. We’ll provide more than 500 pieces of new content this year absolutely free for our readers—including objective evaluations of individual tools and products. Solid carbide: a drill bit as described above, but it’s made entirely from carbide. It’s suitable for drilling into tough materials.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. 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.

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.Kenny’s life around power tools started early. His grandfather was an airplane mechanic in WW2 and took up woodworking as a hobby after retiring from the power industry. Building everything from bookshelves to lazy Susans, he became extremely accomplished while his young grandson observed, fascinated at the way raw wood could turn into something both beautiful and functional. In fact, Kenny still uses several pieces that his grandfather made more than 30 years ago. 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. SDS plus shank - This is another type of slotted drive system. It’s used for most masonry drill bits.
