What the job needs from a drill European concealed hinges usually need two kinds of holes: small pilot holes for the hinge’s mounting screws, and a larger, shallow cup bored into the door. Common cup…
Cedar is soft enough that almost any sharp drill bit can make a hole, but a clean pilot hole takes more care than simply matching the screw’s nominal diameter. Cedar splits readily near ends and…
What you need for hex-head construction screws Hex-head construction screws are driven with a socket-style bit, not a Phillips or square-drive bit. The right bit fits the screw head closely, stays engaged under impact, and…
Hard brick is where an ordinary cordless drill quickly shows its limits. The dense outer face can resist a standard masonry bit, polish the bit’s carbide tip, and overheat a compact motor before the hole…
Choosing a bit for tile, glass, or porcelain is less about buying the biggest set and more about matching the cutting edge to the material. A basic carbide masonry bit can work on some soft…
What plastic expansion anchors can hold Plastic expansion anchors—often called ribbed plastic anchors—are a low-cost option for light-duty attachments to drywall. A screw pushes the anchor’s sides outward against the hole as it goes in.…
A cordless drill clutch controls how much torque reaches the fastener before the chuck stops driving. Set it too low and the screw will sit proud or strip out. Set it too high and you…
Drill bits wander on smooth metal because the cutting edge has nothing to grip when you first squeeze the trigger. The bit skates across the surface, leaving a crescent-shaped scratch or starting the hole off-center.…
The right drill-bit size for a wall anchor is usually printed on the anchor package. If you no longer have the package, match the bit to the anchor body—not the screw—and check that the anchor…
Drilling ceramic tile is mostly a heat and pressure problem. A sharp bit, low drill speed and steady water cooling are more useful than a powerful drill. For occasional holes in ordinary glazed ceramic, a…
