MAKITA’S FIRST OIL PULSE ‘HYDRAULIC’ IMPACT DRIVER CUTS NOISE AND VIBRATION

•  Hydraulic transmission cuts impact noise by 50%
•  Oil pulse system reduces vibration to 7.0m/s²
•  3-stage impact power selection (hard/medium/soft)

The new Makita 18v DTS141 Oil Pulse impact driver introduces a new form of hydraulic transmission that delivers impact power whilst substantially reducing the machine’s operating vibration and noise levels. With existing impact drivers in the Makita range, the impact action is metal-to-metal with the high speed action damped by springs. In the Oil Pulse version hydraulic oil is compressed by a revolutionary rotary drive train and the hydraulic pressure promotes the impact action. The new Makita DTS141 gives two impacts per rotation of the ¼ hex driving shank.

Whilst maximum tightening torque is limited to 40Nm – adequate capacity for the majority of assembly and installation tasks – the impact noise generated by this driver is significantly less than those in the current range. The maximum sound pressure level is 77dB(A) against the 96dB(A) of the traditional products. Similarly, the Oil Pulse system dramatically slashes the vibration rating of the DTS141 down to 7.0m/s² against an established rating of 12.5m/s² for the Makita DTD148 driver. Both features, low noise and vibration, are particularly attractive in modern assembly areas such as white goods manufacturing and some automotive assembly positions where, if a number of impact drivers are being used at the same time, the ambient noise level could be unacceptably high.

The new Makita DTS141 brushless impact driver features the 3-stage impact power and shaft speed selection delivering up to 2,700 impact blows per minute and running up to 3,200rpm in max power selection.  This is suitable for M8 machine screws, M6 high tensile bolts and 125mm coarse thread screws. This body only model has the benefit of Extreme Protection Technology – XPT – protecting against weather and dust ingress for long life and rugged reliability. The compact DTS141 impact driver has a 136mm overall length, weighs just 1.5kg, has an LED job light and electric brake, and comes in a neat, high impact MacPac case.
