Power Tools — FAQ
What size cordless drill do I need for fence installation?
A 20V drill with 1/2-inch chuck and 300+ UWO handles most fence tasks. For wood fences, this powers through pressure-treated posts and drives lag bolts. For chain link, it runs wire twisters efficiently. Avoid 12V drills for professional fence work—they lack sustained power for all-day use.
Can I use a hammer drill for fence installation?
Hammer function helps when drilling into concrete for pool fence posts or metal post anchors. However, most wood fence work doesn't require hammer mode. A standard drill driver with high torque suffices for 90% of fence projects. Consider a hammer drill combo if installing pool fences or masonry anchors regularly.
How long should batteries last when building a fence?
Expect 150-200 holes or 300+ screws from a 2.0Ah battery in pressure-treated wood. Larger 5.0Ah batteries double that runtime. In our tests, the DEWALT 1.3Ah batteries managed 80-100 holes before needing swap. For professional fence builders, 4.0Ah minimum prevents workflow interruptions from frequent battery changes.
Are wire twisting accessories worth it for chain link fences?
Absolutely. Wire twisters cut installation time by 70% while delivering more consistent tension than hand twisting. A $20-30 accessory pays for itself on the first fence by eliminating hand fatigue and ensuring uniform tie strength. They attach to any standard drill and work flawlessly with quality cordless drills.
Do I need a drill guide for pool fence installation?
Yes. Pool fence posts require perfectly perpendicular holes in concrete or decking for safety compliance. Drill guides prevent angled holes that cause leaning posts and failed inspections. The ALLSAFE and YUEYIN guides we tested deliver professional results for under $50, saving hundreds in potential redo costs.
What's the difference between brushless and brushed motors for fencing?
Brushless motors deliver 50% longer runtime and generate less heat during continuous use—critical for drilling hundreds of holes. They also require less maintenance and last 3-5x longer. While brushed drills cost less, brushless models like upgraded DEWALT variants pay for themselves through battery savings and durability on large fence projects.
