Cordless 4 Mode Impact Driver
PRODUCT P 1/ 18 L
CONCEPT AND MAIN APPLICATIONS
Model BTP131 Cordless 4 mode Impact Driver is an advanced version of model BTP130. While maintaining the same high versatility as Model BTP130, BTP131 additionally features more compact design achieved by using BLDC motor (BrushLess DC motor) and Makita’s first electronic clutch mechanism. This product is powered by 14.4V-1.3Ah Li-ion battery BL1415 and 14.4V-3.0Ah Li-ion battery BL1430. This product is available in the following variations. Model No.
