Makita Genuine 310345-1 Piston Cylinder For HR2300/26/261 SDS Drills

The Makita 310345-1 Piston Cylinder is a genuine OEM replacement component for the percussion mechanism in compatible Makita SDS-Plus rotary hammer drills, including the HR2300, HR2610, HR2611 and DHR243 series. This precision-machined metal alloy sleeve sits at the heart of the hammering action, guiding the piston and striker to compress air and deliver consistent, controlled impact blows. When the original cylinder becomes worn or scored through extended use, impact performance drops noticeably — this direct-fit replacement restores that efficiency without the need for modification or specialist tooling. As a genuine Makita part, the 310345-1 is manufactured to the correct tolerances, ensuring proper alignment of internal moving parts and accurate sealing when used alongside the tool's serviceable O-rings and grease. This is particularly important for maintaining compression and preventing energy loss during repetitive drilling and chiselling into concrete, masonry and stone. The cylinder is suited to both reactive repairs and planned preventative maintenance during scheduled overhauls. For contractors and tradespeople who rely on their rotary hammers day-to-day, fitting a genuine part rather than a generic alternative helps protect the wider tool investment and supports a longer service life.
