For a long cable run through thick timber, the best auger bit is usually a ship auger in the length that actually reaches the far side—not the longest bit you can find. Ship augers cut quickly, clear chips well and are made for deep holes. But they can grab hard, and a long bit magnifies … Read more
Repeated pipe holes through floor joists are where a self-feed bit earns its keep. Compared with a spade bit, it starts more cleanly, pulls itself through the timber, and usually leaves a rounder hole with less pressure on the drill. The catch is that self-feed bits are not automatically the right choice for every joist, … Read more
For drilling holes through framing lumber, the choice between a ship auger and a standard auger bit comes down to hole size, drilling speed, chip removal, and the drill you have. Both are made for wood, but their cutting geometry and intended use differ. A ship auger is usually the better choice for repeated, deep … Read more
For deep holes in green timber, a long, self-feeding auger bit is usually the best starting point—but the bit is only half the decision. Hole depth, wood diameter, and the drill’s ability to handle sustained torque matter just as much. A large auger can grab hard enough to twist a drill out of your hands … Read more
Short answer: which one bores faster? For ordinary holes through framing lumber, both bits can make quick work of a stud when driven by a suitable drill. The Irwin Speedbor is the better pick for frequent, aggressive boring where speed and chip clearing matter. The Bosch Daredevil is often the better-value choice for typical electrical, … Read more
Installing a recessed fixture in plaster is harder than cutting drywall. Plaster can chip at the surface, crack around the opening, and hide wood lath or metal mesh behind it. The best adjustable hole cutter is one that makes a controlled, clean circle without forcing you to lean heavily on the ceiling. As an Amazon … Read more
Choosing a self-feed bit for rough plumbing starts with the hole the pipe or fitting needs—not the biggest cutter your drill can turn. Too small, and the pipe won’t pass through. Too large, and you weaken the framing, make a rougher repair, and put more strain on the tool. Measure the actual pipe and account … Read more
The short answer For occasional holes in ordinary softwood joists, a spade bit is usually the better buy. It costs less, cuts quickly, and is easy to find in the sizes used for common cable and pipe work. Choose an auger bit when you need a deeper, straighter hole, expect to drill many holes, or … Read more
The short answer For most holes in thin aluminum sheet, a bi-metal hole saw is the sensible buy. It costs less, cuts cleanly when sharp and properly lubricated, and is more forgiving if you occasionally use it on wood or plastic. A carbide-tipped hole saw is worth the extra cost when you make many holes, … Read more
Porcelain is hard, brittle, and unforgiving. A standard bi-metal hole saw will usually skate across the glaze, overheat, and dull before it makes useful progress. For faucet shanks, toilet-supply lines, shower valves, and other plumbing penetrations, the right choice is a diamond-grit hole saw used with controlled speed and steady water cooling. The best all-around … Read more
