What the AI looks for in Power Rotary Hammers
- Bit system
- SDS-plus for anchoring and holes up to about 1 inch; SDS-MAX for larger holes and heavy chiseling. The shank system determines bit compatibility and the tool's capacity.
- Impact energy
- Compare in joules or foot-pounds within the same class from reputable brands. Impact energy, not motor watts, drives drilling speed in concrete.
- Modes
- Three modes: rotary hammer, drill only, and hammer only. The hammer-only mode lets one tool also chip tile and mortar.
- Kickback protection
- Prefer an electronic anti-rotation clutch (for example Bosch KickBack Control, Milwaukee AUTOSTOP, DeWalt E-Clutch). A bound bit can spin the tool violently and injure the user's wrist.
- Dust extraction
- Use an on-tool shroud or HEPA extractor when drilling concrete. Silica dust exposure is the main health hazard.
Brands that matter
- Hilti: Professional reference for SDS rotary hammers.
- Bosch: Inventor of SDS; strong corded and cordless range.
- Makita: Durable corded models and LXT cordless options.
- DeWalt: Popular cordless SDS-plus with an anti-rotation clutch.
- Milwaukee: M18 FUEL rotary hammers with dust extractor accessories.
- Metabo HPT: Value professional rotary hammers.
What to avoid
- Unbranded SDS-plus kits advertising high joule figures with no service network.
- Rotary hammers without a clutch or anti-rotation protection.
- Using SDS-plus tools for routine large-diameter holes that need SDS-MAX.
Questions
Do SDS-plus and SDS-MAX bits interchange?
No. They are different shank sizes and need matching tools.
