{"product_id":"yato-akkupuukkosahasarja-18v-4-0-ah-li-ion-akku","title":"Yato Cordless Reciprocating Saw Kit 18V 4.0 Ah Li-Ion Battery","description":"\u003cp\u003eThe\u003cb\u003e Yato 18V cordless reciprocating saw\u003c\/b\u003e is powered by an\u003cb\u003e 18V DC \u003c\/b\u003e(direct current) source and a standard \u003cb\u003e4000 mAh Li-Ion battery\u003c\/b\u003e. The saw's key performance metrics are a \u003cb\u003estroke rate of 0–3000 min⁻¹\u003c\/b\u003e combined with a \u003cb\u003e22 mm stroke length\u003c\/b\u003e, which enables efficient material removal. The standard \u003cb\u003e1\/2″ (12.7 mm) chuck\u003c\/b\u003e ensures mechanical compatibility with the most common reciprocating saw blades on the market, regardless of manufacturer. The total weight of the tool has been optimized to be minimal, with the saw body itself weighing only \u003cb\u003e1.5 kg\u003c\/b\u003e.\u003c\/p\u003e\n\u003cp\u003eIn terms of powertrain and motor, the device utilizes \u003cstrong\u003ebrushless motor technology\u003c\/strong\u003e. The brushless design eliminates physical friction between the rotor and stator, which reduces the device's heat load and improves the efficiency of the \u003cb\u003e18V battery\u003c\/b\u003e compared to a traditional brushed motor, extending operating time. The tool's control electronics support mechanical stroke rate adjustment via the switch response without a separate electronic speed pre-selection. The device also features an integrated \u003cb\u003ebattery charge indicator\u003c\/b\u003e to enable accurate electrical power monitoring.\u003c\/p\u003e\n\u003cp\u003eThe cutting capacity is mechanically calibrated according to material densities; the device's certified \u003cb\u003emaximum cutting depth for wood is 150 mm\u003c\/b\u003e, and the corresponding maximum depth for \u003cb\u003emetal is 6 mm\u003c\/b\u003e. Structural electrical safety meets the requirements of \u003cb\u003einsulation class III\u003c\/b\u003e. The system's acoustic emission during operation produces a \u003cb\u003esound pressure level (LpA) of 87.3 ± 5.0 dB(A)\u003c\/b\u003e and a \u003cb\u003esound power level (LwA) of 95.3 ± 5.0 dB(A)\u003c\/b\u003e, necessitating the use of professional protective equipment.\u003c\/p\u003e\n\u003cp\u003eThe mechanical enclosure rating of the tool body is \u003cb\u003eIPX0\u003c\/b\u003e, meaning it is unprotected against water ingress. Mechanical vibration exposure in the control handles varies at levels of \u003cb\u003e7.2 ± 1.5 \/ 9.4 ± 1.5 m\/s²\u003c\/b\u003e depending on the material being cut and the blade used. The assembly includes a fast charger, which allows the included \u003cb\u003e4.0 Ah capacity\u003c\/b\u003e battery to reach maximum electrical charge in exactly \u003cb\u003e2 hours\u003c\/b\u003e.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eIntended use and suitability:\u003c\/h3\u003e\n\u003cp\u003eThe device's 18V voltage and brushless motor design are suitable for mobile installation work and mechanical dismantling.
