Additions to brushless motor tool range
21 November 2014
Three new tools featuring ‘BL’ brushless-motor technology have been introduced by Makita. They have a reduced overall size, with the body length up to 20mm shorter, making them more compact and more manoeuvrable than previous models.
The Makita DHP481 LXT combi drill is powered by an 18v Lithium-ion battery and the brushless motor, which is said to enable up to twice the run-time of traditional motors, is rated at 640W power output. This two-speed drill will run up to 2100rpm in high gear and 550rpm in low. It will deliver 31,500 impacts/min in high gear and 8250 impacts/min in low gear.
The 13mm single sleeve keyless chuck enables 16mm capacity in masonry, 13mm in steel and 76mm in timber. Torque can be adjusted to 21 alternative settings and has a dedicated drilling mode. The DHP481 will generate 60Nm of fastening torque (soft joint) and 115Nm (hard joint), the highest torque yet from the Makita 18v range.
There are twin LED job lights with afterglow once the variable speed trigger is released and a new side handle configuration gives light tool control. Coupled with the soft grip ergonomic handle design positive drill-driver capability is assured. The brushless Combi weighs just 2.7kg, is available with two 5.0Ah or two 4.0Ah batteries, and is supplied in the Makita ‘Makpac’ connector case or as a body only unit (no case) where existing battery stocks are available.
The new Makita DDF481 LXT drill driver mirrors the main features of the DHP481, without the percussion function, and will run up to 2100rpm in high gear and 550rpm in low gear.
The new Makita DTW281 high torque impact wrench is rated at 280W and will generate up to 280Nm tightening torque. This 1/2inch square drive impact wrench has a three-stage power selection function that will produce 3500 impacts/min in high, 2600 impacts/min in medium and 1800 impacts/min in low setting. This enables torque flexibility for varying applications to prevent over-tightening which could damage a fixing.
The Makita DTW281 will drive home an M20 standard bolt and an M16 high tensile bolt. This new, powerful impact wrench weighs just 1.7kg and at 147mm overall length is 18mm shorter and more compact than the current DTW251 model. This model features the battery fuel gauge system which indicates with three lights showing that more than 50% battery capacity is available; with two lights showing there is 20 to 50% capacity available and with a single light showing less than 20% full battery capacity remains.
