Large holes are where ordinary twist bits start to struggle. A hole saw, Forstner bit, spade bit, or auger can cut a clean opening, but each behaves differently—and any of them can tear out the… 

Hardwood makes small differences in a countersink bit easy to see. A dull cutter can burn the hole, a coarse cutter can leave torn fibers around the rim, and a countersink that is too deep… 

Quick answer For most cordless-drill owners, a keyless chuck is easier to use. You can loosen and tighten it by hand, so changing from a pilot bit to a driver bit takes seconds and does… 

A hammer drill can make quick work of brick and concrete, but leaning on it harder is not the way to keep the bit cool. Friction builds when the cutting edges stop clearing dust, the… 

Choosing an impact driver for sheet-metal screws Self-tapping screws can be quick to install with an impact driver, but sheet metal is easy to strip or deform. The right tool is less about maximum torque… 

The right wall anchor depends on the wall, the load, and how often the fastener may be disturbed. Plastic expansion anchors are inexpensive and useful for light loads. Metal expansion anchors generally grip more firmly… 

A standard drill bit and a hole saw can both make holes, but they solve different problems. Drill bits cut a relatively small opening with their tip and cutting edges. A hole saw cuts around… 

Flat wood bits, also called spade bits, are a quick, inexpensive way to bore utility holes through studs for cable, pipe and other services. They cut faster than many general-purpose bits, but they are not… 

Removing deck screws is one of the jobs where an impact driver usually earns its place. It delivers short bursts of rotational force that help break loose rusted, overdriven, or partially seized screws without requiring… 

Fiberglass tubs are thin, flexible, and easy to chip or crack if a bit grabs the surface. For most clean holes, a sharp, ordinary twist bit is enough; the bigger risks are using hammer mode,…
