Description
The Yato SDS+ cordless rotary hammer set runs on 18 V direct current and delivers 2.8 J of impact energy. The device is powered by a brushless motor that turns the SDS+ chuck at 0–950 min⁻¹ and produces an impact rate of 0–4700 min⁻¹. The assembly uses electronic speed control, which optimises torque and impact force when drilling into hard materials.
The SDS-Plus chuck of the device allows quick mechanical fitting of bits and efficient transfer of impact energy without extra tools. The brushless motor design minimises rotor friction and heat load, which extends battery run time and the mechanical life of the device compared with traditional carbon brush motors. The rotary hammer body alone weighs 2.8 kg.
The system offers three mechanical operating modes: drilling, hammer drilling and chiselling. This allows holes of up to 26 mm to be drilled in concrete with spiral bits and 68 mm holes to be bored in sand-lime or ceramic brick with core bits. The maximum capacity of the device is 13 mm in steel and 30 mm in wood.
The cordless rotary hammer set is supplied with two 4.0 Ah Li-Ion batteries and a two-hour fast charger. The tool has an integrated battery charge indicator for real-time electrical power monitoring. The device has insulation class III and enclosure rating IPX0, and it reaches a sound power of 105.5 ± 3.0 dB(A) at maximum load.
Intended use and suitability:
The cordless rotary hammer is designed for serial installation work in the construction industry that demands efficiency and for heavy penetration work. The brushless motor and hammer mechanism of the device are calibrated for large-scale drilling and chiselling tasks.
- Penetrating concrete and masonry: The 2.8 J impact energy and 0-4700 min⁻¹ impact rate allow anchor holes and installation penetrations of up to 26 mm diameter to be drilled in concrete.
- Demolition of structural parts: The chiselling mode and SDS+ chisels support mechanical removal of hard stone materials, tiles and joints without rotary movement.
- Mobile installation work: The system of two 4.0 Ah (72 Wh) batteries allows a continuous power supply at sites without a fixed mains supply.

Yato YT-827724 instructions for use:
Mechanical steps for fitting and operating the device at industrial sites.
- 1. Connecting the power source: Use the supplied charger to make sure the 18V battery is fully charged. Push the battery into the slide rail at the bottom of the handle until the mechanical lock clicks into place.
- 2. Fitting the bit: Pull the locking collar of the SDS-Plus chuck back, insert a clean, lightly greased bit into the chuck and release the collar to make sure it locks.
- 3. Selecting the operating mode: Turn the mechanical selector on the side of the device to the drilling, hammer drilling or chiselling symbol according to the work step you want.
- 4. Adjusting the depth stop: Open the mechanical lock of the auxiliary handle, set the metal depth stop to the required measurement to ensure the drilling depth and tighten the handle back in place.
- 5. Drilling process: Place the device perpendicular to the surface. Press the trigger to adjust the speed in the range 0–950 min⁻¹. Avoid excessive physical pressure to support optimal operation of the pneumatic hammer mechanism.
Warnings:
Critical technical warnings to ensure electrical and occupational safety.
- Noise exposure: At maximum load the tool produces a sound power of 105.5 dB(A). Wearing ear defenders that meet the standards is mandatory to avoid permanent hearing damage.
- Vibration exposure: The device’s vibration level of 18.23 m/s² requires continuous monitoring of exposure time in long demolition work to prevent circulatory disorders.
- Electrical and moisture safety: Enclosure rating IPX0 offers no protection against water ingress. Exposing the device to moisture causes a risk of short circuit in the electrical components.
- Mechanical kickback: Sudden jamming of the drill bit, for example on reinforcing steel in concrete, can make the device twist violently and uncontrollably. Using the auxiliary handle and operating with both hands is essential.
Frequently asked questions (FAQ):
- Do SDS+ bits from other manufacturers fit the Yato YT-827724? Yes, the SDS-Plus quick-change chuck of the device is standardised and supports all SDS+ drill bits and chisels that meet the industry standard, whatever the manufacturer.
- Can the device drill without the hammer function? Yes, the mechanical selector switch can turn the pneumatic hammer mechanism off completely, so the device works with rotary movement only, for example when drilling wood or steel.
- How long does it take to charge the 4.0Ah battery from empty to full? The fast charger supplied with the device restores the 4.0Ah (72 Wh) lithium-ion battery to full charge in exactly two hours.
- What are the maximum capacities of the device in different materials? The device can drill 26 mm holes in concrete with a spiral bit, 68 mm holes in brick with a core bit, 13 mm holes in steel and 30 mm holes in wood.
Recycling instructions:
Recycling instructions by material in line with the regulations for professional use.
