Description
Overview:
This Helical Gear is a genuine Makita replacement part for the HR2811F and HR2811FT hammer drills (MPN: 226653-9). It is a precision‐machined steel gear designed to transfer motor power smoothly through the drill's gearbox, helping to maintain consistent hammering and rotation performance. The helical tooth profile reduces vibration and noise compared with straight-cut gears, supporting efficient operation under load. Built for the demands of site work and regular DIY use, it restores performance when the original gear shows signs of wear such as slipping, rough running, or loss of drive. As an OEM component, it matches factory tolerances for reliable fitment and long service life in Makita SDS-plus rotary hammer drills.
