Detailed Review
The GBH2-28L SDS-plus Bulldog Xtreme Max rotary hammer is a dedicated 1-1/8-inch concrete and masonry tool built for heavy drilling and chiseling tasks. Powered by an 8.5-amp motor that produces 2.4 Ft.-Lbs. of impact energy, it gives contractors and serious DIYers the force needed to power through dense materials efficiently.
Operation is centered around a multi-function selector that offers three distinct modes: drilling only, hammer drilling, and chiseling. Bit management is handled via a tool-free SDS-plus system with automatic locking, while Vario-Lock lets you adjust and fix chisel angles to suit your working posture. For added accuracy when starting holes, the variable-speed trigger includes a reversing feature.
Handling and safety are reinforced by two key systems. Counter-balanced Vibration Control cushions the tool during operation to keep you comfortable during extended work sessions, while KickBack Control uses an internal sensor to halt rotation immediately if a bit binds. The D-handle shape provides a secure grip, especially for downward and overhead tasks, and an integrated HammerHook offers a quick way to hang the tool between uses.
Because this tool uses a dedicated SDS-plus chuck, standard smooth-shank drill bits will not fit without an adapter. The corded 8.5-amp design also means you must work near an outlet or extension cord, and the D-handle body adds length that might be noticeable in confined workspaces.
Verdict: The GBH2-28L is an ideal choice for users needing reliable hammer drilling and chiseling capability with built-in bind-up protection. It delivers strong impact energy and versatile mode selection for heavy-duty masonry projects.
