Melamine shelving is easy to cut badly. The particleboard core cuts quickly, but the thin decorative coating chips when a tooth lifts it away from the core. A jigsaw can produce a clean, usable edge, but the blade choice matters more than motor power. For the cleanest visible top edge, use a reverse-tooth jigsaw blade … Read more
What the arbor does A hole saw arbor connects the saw to a drill and, in most setups, holds the pilot bit that keeps the cut centered. The right arbor fits both the hole saw and the drill, but it also needs to suit the material, hole size, and amount of work. A poorly matched … Read more
For large holes in steel, an annular cutter usually produces the cleaner, faster result. A hole saw can still be the better buy for occasional work, thin sheet, and jobs where you already own a handheld drill. The right choice depends on steel thickness, hole diameter, machine stability, and how much cleanup you can tolerate. … Read more
Quick pick: a step bit is not always the right tool For enlarging a knockout in a thin steel electrical panel, a step bit is a good choice when the new hole is within its rated capacity and you can keep the bit centered. Buy a bit with clearly marked steps, a usable diameter range, … Read more
Stainless steel is not especially hard, but it is unforgiving. A drill bit that cuts ordinary mild steel can become dull within a few holes if it spins too fast, rubs instead of cutting, or lets the workpiece heat up. For most stainless-steel drilling, the best all-around choice is a quality cobalt high-speed-steel (HSS) set, … Read more
On paper, a brushless drill often promises longer runtime and more power. Under sustained high load, the difference is less about a dramatic speed increase and more about how efficiently each motor handles heat, how long it can keep working before the battery needs changing, and how well the tool tolerates repeated hard use. That … Read more
The Milwaukee M12 Fuel 3404 and DeWalt DCD703 are compact 12-volt drills suited to electrical work where a full-size drill is awkward. Both can handle pilot holes, device boxes and routine fastening. The difference is in how they get into tight spots: Milwaukee is a conventional compact drill, while DeWalt’s right-angle head and interchangeable attachments … Read more
The short version The DeWalt DCD800 and Makita XFD14 are 18V-class, brushless drills built for demanding work, but neither is a hole-saw specialist. Both can make repeated holes in wood or other suitable materials when paired with a sharp saw and the right technique. The better choice depends less on headline torque than on how … Read more
Large auger bits expose the difference between a strong hammer drill and a drill that only looks strong on its specification sheet. A 1-inch bit is easy work for both the Bosch GSR18V-1330C and Milwaukee 2903-20. A 2-inch self-feeding bit, a long ship auger, or a large spade bit in wet framing lumber is where … Read more
A keyed chuck generally holds a large bit more securely than a keyless chuck when the drill is under heavy torque, especially with smooth-shank bits or repeated starts and stops. The trade-off is slower bit changes and the need to keep track of the chuck key. For ordinary drilling, a good keyless chuck is often … Read more
