Description
Yato cordless drill 55 Nm 2×4 Ah set (YT-827821) includes an 18 V drill/driver with a brushless motor and a hammer drilling function, two 4 Ah Li-Ion batteries, a charger, an auxiliary handle and a case. With two batteries, one battery can charge while you work with the other. The maximum torque is 55 Nm, and the tool drills, hammer drills, and drives and removes screws and bolts.
The two-speed gearbox gives speeds of 0–450 and 0–1800 min⁻¹. The lower speed is intended for screwing and the higher one for drilling and hammer drilling. The speed is also adjusted steplessly by pressing the trigger, and the spindle brake stops the chuck when the trigger is released.
The self-centring 13 mm drill chuck is tightened by hand while holding the chuck ring. The torque selector has numbered clutch settings for screwing and drill and hammer symbols for drilling and hammer drilling; in the drilling and impact positions, the clutch does not limit the torque.
The weight of the tool without the battery is 1.0 kg. The charger (200–240 V~, output 21.5 V DC / 2.2 A) charges a 4 Ah battery in about 2 hours. The body has an LED work light and a metal belt hook. The sound power level is 93.8 dB(A), so hearing protection is used when hammer drilling.
Uses and suitability:
The drill/driver is designed for drilling holes in wood, wood-based panels and metals and for driving and removing screws and bolts. Hammer drilling makes drilling easier in certain masonry materials; impact is not used for wood, metal or plastic.
- Installation and finishing work: Fixing furniture, mouldings, rails and brackets with adjustable torque.
- Woodwork: Holes in wood and boards and driving wood screws into pilot holes.
- Metalwork: Holes in thin sheet and profiles with a metal drill bit.
- Plug fixings: Holes in brick and masonry by hammer drilling with a masonry bit; first a short pilot hole without impact.
The set batteries fit other Yato 18 V tools, such as the Yato cordless jigsaw 18V, body only, and a suitable extra battery is the Yato 18V Li-Ion battery. A higher-torque alternative from the same system is the Yato cordless impact drill 18V 120Nm, brushless motor, body only.

Yato cordless drill 55 Nm 2×4 Ah user instructions:
Charging and battery: The batteries are supplied uncharged. Place the battery in the charger and plug the charger into a socket; the indicator light shows the charging status. Charge only in a closed, dry room under supervision. Slide the charged battery into the battery slot until the latches lock.
Fitting the bit: Hold the chuck ring and turn the drill chuck to open the jaws. Push the bit in all the way and close the jaws. Screwdriver bits are fitted with a bit holder. Check that the bit is held firmly without play.
Screwdriving: Select the lower speed and the screw symbol, and set the clutch number according to the size of the fastener and the material. Start with the lowest setting and test on scrap material. When the clutch slips, stop tightening. Drill a pilot hole for wood screws.
Drilling and hammer drilling: Check that there are no electrical cables at the drilling point. Set the selector to the drill symbol and select the higher speed. Hold the tool perpendicular to the surface and press in line with the bit. In masonry, first drill a short pilot hole without impact and then switch to the hammer symbol.
Maintenance and storage: Remove the battery and clean the housing, ventilation openings and switches with compressed air (max. 0.3 MPa), a brush or a dry cloth; the housing can be wiped with a cloth moistened with soapy water. Store in a dry, ventilated place below 40 °C.
Warnings:
- Read the user manual before use. Wear safety glasses, hearing protection and protective gloves, especially when hammer drilling.
- Remove the battery before changing accessories, making adjustments and maintenance. Do not change settings while the tool is running.
- Hold the tool firmly and use the auxiliary handle: if the bit jams, the reaction torque can twist the tool.
- Hold the drill by its insulated gripping surfaces if the bit may hit hidden electrical wiring.
- Do not drill with the screw symbol selected: if the clutch slips during drilling, it can damage the bit and reduce control.
- Start drilling at low speed; do not exceed the maximum permitted speed of the bit. The temperature of the outer surfaces must not exceed 60 °C.
- Charge the batteries only with a Yato charger; do not short-circuit the battery terminals or expose the battery to temperatures above 130 °C. Not for use by children. Do not expose the tool to rain or moisture.
