Construction screws put more strain on a driver bit than ordinary wood screws. Long structural screws, dense lumber and repeated fastening can round a tip or twist a thin bit, especially in an impact driver.…
Best drill bits for galvanized steel For most holes in galvanized sheet or light-gauge steel, a sharp cobalt-alloy twist bit is a dependable choice. A standard high-speed steel (HSS) bit can also work well for…
Impact-rated hex shank bits are made for the repeated twisting loads of an impact driver. They are not simply ordinary bits with a different label: the better ones use tougher steel and a torsion zone…
The right lubricant keeps a drill bit cooler, reduces friction and helps it cut cleanly. For occasional holes in mild steel, a small bottle of cutting oil is usually enough. Stainless steel, thick stock and…
For expansion anchors, the bit has one critical job: make a straight, round hole at the diameter and depth specified for the anchor. A bit that is dull, undersized, or allowed to wander can leave…
A medicine cabinet is a poor place to guess about wall anchors. A loaded cabinet can weigh several dozen pounds, and opening its door puts repeated outward force on the fasteners. The safest option is…
