Best Cordless Drill NZ: Which to Buy
Drill specs get thrown around like they all matter equally. For most home use, voltage and torque numbers matter less than which battery platform you're buying into.
Voltage and torque: what actually matters at home
Cordless drills are commonly sold at 12V, 18V/20V and higher for heavier trade tools. For general home DIY — flat-pack furniture, hanging shelves, deck screws, the occasional masonry hole — an 18V drill with a two-speed gearbox and reasonable torque settings (measured in Nm, usually adjustable via a clutch collar) is more than enough. Higher voltage mainly buys you more sustained power for repeated heavy-duty tasks — trade users drilling into concrete or driving long screws all day genuinely need it, but most homeowners are paying for headroom they'll rarely use.
Torque settings (the clutch) matter more day-to-day than raw power — a good clutch lets you drive screws into soft materials like plasterboard without stripping the screw head or punching through, which is the single most common frustration first-time drill users run into.
Battery ecosystem lock-in: the decision that outlasts the drill
This is the part people underestimate. Once you buy into a brand's battery platform (Makita's 18V LXT, DeWalt's 20V MAX, Ryobi's One+, Bosch's 18V system), every future tool you buy in that range — impact driver, circular saw, angle grinder, even leaf blowers and vacuums for some brands — can share the same batteries and charger. That means your second and third cordless tool purchase gets meaningfully cheaper (bare tool only, no battery/charger needed) if you stick with the same brand.
Picking a platform, not just a drill
Before buying your first cordless drill, think about what other tools you're likely to want in the next few years. Ryobi's One+ platform (widely stocked at Bunnings and Mitre 10, and PB Tech carries some models) is popular for home DIYers because it covers an enormous range of garden and home tools at accessible prices. Makita and DeWalt lean more trade-oriented with higher build quality and higher prices, but their batteries and tools hold value and durability better under heavy repeated use. Once you're a few tools deep into a platform, switching brands means starting your battery collection from scratch — a real cost, not just inconvenience.
DIY vs trade-grade: an honest line
Trade-grade drills (brushless motors, higher-capacity batteries, metal gear housings) cost noticeably more but survive years of daily commercial use — dropped on concrete, used all day, every day. For occasional home use, a brushed motor and a smaller battery is genuinely fine and will likely outlast your patience for DIY projects. Brushless motors are worth the extra cost if you'll use the drill weekly or for longer sessions — they run cooler, more efficiently, and the battery lasts longer per charge.
- Occasional home DIY: an 18V brushed drill with 2 batteries and a case, from any major brand, is enough.
- Regular DIY or small trade jobs: step up to brushless, higher torque, and consider the platform you'll build on.
- Battery platform: pick based on which other tools you'll likely buy — not just the drill itself.
- Clutch settings: more settings = finer control, genuinely useful for delicate materials.
- Hammer function: only needed if you're regularly drilling into brick or concrete.
