Built for consistent effectiveness over the long term, the HM1111C is double insulated to protect against surges, features an integrated, grease packed lubrication system for reduced maintenance demands, & is fitted with Makita's Anti Vibration technology for decreased strain to tool & user when working with particularly resistant materials. Twelve different bit angles keep the tool easy to control when chipping, scaling & demolishing, while the HM1111C's wrap-around handle can be angle adjusted both vertically & horizontally for a comfortable hold in different working postures. Features & BenefitsConstant speed irrespective of the load: the motor automatically compensates for resistanceAnti Vibration technology: absorbs excess kinetic energy for reduced strain on the arms & shouldersDouble Insulated: protects the tool against surges & overload12 different bit angles: improved performance when chipping, scaling or demolishingSoft start feature: smooth starting safeguards
