IRIS OHYAMA RD110-W: Is 3.5 N·m Enough for Your Tasks?

## Bottom line: a light-duty screwdriver, not a drill The IRIS OHYAMA RD110-W is a 3.6V cordless electric screwdriver listed with a maximum tightening torque of 3.5 N·m and 200 rpm [S1]. It weighs 0.38 kg and measures 14.5 × 4.5 × 12 cm, so the case for it rests on light work: assembling flat-pack furniture, tightening screws in pre-drilled wood or plastic, and small household fixes [S1]. The listing price at the time of writing was ¥3,284 against a ¥4,999 list price; prices change, so re-check before ordering. ## Who it fits - People who want hand-screwdriver work made easier, but do not need a heavy drill or impact driver. - First-time tool buyers who find a full-size drill excessive for furniture and fittings. - Anyone prioritising low weight (0.38 kg) and a compact body [S1]. ## Who should skip it - Anyone planning to drill into concrete, mortar, steel or hard hardwood. The supplied source does not state a drilling capacity, and 3.5 N·m should not be read as one [S1]. - Frequent or continuous use: runtime is stated as about 60 minutes per charge, with a 3–5 hour charge time [S1]. - Outdoor use in winter or in hot locations: the stated operating temperature range is about 10–40°C [S1]. ## Limitations, and what is unverified - The ~60-minute runtime, ~250-cycle battery life and 3–5 hour charge time are figures given in the supplied product data, not results of independent testing [S1]. Real runtime depends on screw size, material and load. - The charger is listed as AC100–240V, 50/60Hz input, DC5V 0.5A 2.5W max output [S1]. - Not established by the source: included accessories (bits, case), clutch settings, LED light, forward/reverse switching, warranty length, Japanese-language manual or app support, and whether replacement batteries are sold separately. Check the product page and the Japanese warranty terms before buying, especially whether a bit is included. - It is sold as an electric screwdriver; drilling performance is not documented in the source.
