What tools do I need for basic home repairs?
The essential 5: cordless drill (for hanging shelves, assembling furniture), digital multimeter (for electrical diagnosis), quality screwdriver set with Torx and Pentalobe bits, a tape measure, and a 4-in-1 adjustable wrench. These cover 80% of household repairs for under $100 total.
What voltage cordless drill is best for home use?
For most home tasks (drilling wood, driving screws, light masonry with concrete bits), a 18–20V drill is ideal. 12V drills are lighter but lack torque for 3+ mm steel. 20V drills from DEKO, Black+Decker, and Ryobi all deliver adequate power for DIY without contractor-grade price.
Is a temperature-controlled soldering iron necessary?
Yes, if you work on PCBs, laptops, or smartphones. Uncontrolled irons (typically 450°C+) burn solder pads, lift traces, and damage components. A temperature-controlled iron set to 320–350°C makes clean joints in 1–2 seconds. The $22–38 investment pays off on the first repair.
Can a digital multimeter test car batteries?
Yes. A healthy 12V car battery reads 12.6–12.8V at rest. Below 12.2V indicates sulfation. Most DMMs including the Tacklife DM11 handle automotive 12–24V DC measurement. Load testing requires a dedicated battery tester, but a DMM gives you a fast first diagnosis.
What is a Pentalobe screwdriver and do I need one?
Pentalobe is Apple's proprietary 5-lobe screw format used on all iPhones, most MacBooks, and AirPods. No standard Phillips or Torx driver fits it. A Pentalobe P2 (iPhone) and P5 (MacBook) are essential for any Apple repair. WORKPRO's 130-piece set includes both.
How far can an inspection camera reach?
Standard inspection cameras come in 1 m, 3.5 m, and 5 m cable lengths. For behind-drywall inspections and car cavities, 3.5 m is usually sufficient. For plumbing snaking or long cable conduits, use 5–10 m cameras. The DS350's 5 m semi-rigid cable handles most DIY scenarios.
