When selecting a grease for a rotary hammer, consider the type of bits you use (SDS-Plus vs SDS-Max), the volume you need for regular maintenance, and whether the product is compatible with your specific hammer model. The following sections review five relevant products with key features to help you decide which one fits your workflow and tool maintenance routine.
Makita Hammer Bit Grease
Makita’s grease vessel is designed specifically for rotary and hammer bits. It provides a dedicated reservoir for tool grease, helping to lubricate internal bit interfaces and reduce wear. The package dimensions indicate a compact setup suitable for shop benches or job sites with limited space. This grease is intended to support smoother operation of rotary and hammer bits by maintaining a protective film and reducing friction where the bit meets the chuck and bit journals.
Bosch Professional 100 ml Grease Tube
Bosch offers a 100 ml grease tube designed for SDS-Max and SDS-Plus drill bits and chisels. The grease aims to lower friction to prolong the life of the bit and accessory tools, while enabling easy application with one hand. Bosch emphasizes durability improvements and a broad range of uses, with grease volumes aligned to typical maintenance cycles for mid- to heavy-duty rotary hammers.
Makita A90582 Hammer Grease
Makita’s A90582 grease is a compact option that fits a small reservoir and is designed to lubricate the grease system of the hammer. A 1 oz size is typically suitable for periodic maintenance and topping off the reservoir, defending against damage and prolonging overall tool life. It targets lubrication needs within the tool’s moving parts, helping maintain consistent operation in demanding drilling tasks.
Berserker 1.76 Oz Lubricant Grease
Berserker’s grease is marketed for broad compatibility with Berserker electric hammers and many rotary hammers on the market. It’s positioned to increase machine efficiency, extend tool life, and prevent damage. The product suggests typical fill quantities around 20–30 g per fill and recommends monitoring tool performance to determine when reapplication is needed, making it suitable for ongoing maintenance by professional operators and DIY users alike.
Makita Hammer Grease 30 g
Makita’s 30 g hammer grease is suitable for both SDS-Plus and SDS-Max hammer drills. The compact size makes it convenient for on-site maintenance and top-off applications to prolong tool service life. It is designed to work with the hammer grease reservoir and internal components, contributing to smoother operation and reduced wear during extended drilling sessions.
Buying Guide
Key considerations when purchasing grease for rotary hammers include compatibility, application method, and volume. First, verify whether your drill uses SDS-Plus or SDS-Max bits, as some greases are formulated specifically for one system or another. Second, assess the ease of application—some products come in syringes or self-sealing cartridges that allow one-handed use on a busy job site. Third, consider the required maintenance cadence: heavier-duty hammers may need larger volumes or more frequent top-offs. Finally, look at brand reputation and whether the grease is designed to protect the grease reservoir, bit interface, and internal collars from wear. Comparing options helps balance cost, performance, and tool longevity across different hammer models.
For a balanced approach, pair a reliable grease with a compatible set of bits and routine maintenance checks. Regularly inspecting bit wear, reservoir levels, and the lubrication film can prevent grinding noises, overheating, and premature failure. If you operate multiple hammer models, maintaining a small stock of both SDS-Plus and SDS-Max compatible greases ensures readiness for diverse jobs without interrupting workflow.
