Bosch GXL12V-220B22 12V Combo Kit vs Bosch 18V Hammer Drill & Freak Impact Combo Kit

Buy the GXL12V-220B22 if you want a light, compact 12V kit for cabinet work, assembly and overhead driving; the 1.6 lb drill and 5.4 in impact head are easy to hold all day. Buy the restored L18V233B25RT if you need real hammer-drill masonry capability, a 1/2 in chuck and the Freak's socket-and-bit impact, and you accept a heavier tool and a refurbished unit. The Bosch 12V line is widely praised for size and smooth triggers; the 18V Freak is liked for its two-in-one drive but owners note its bulk.

• Choose the Bosch 12V Max kit if your work is light-to-medium fastening, tight-space driving and drilling in wood and metal, and you want the smallest, lightest two-tool setup.
• Choose the restored Bosch 18V kit if you drill masonry, turn large bits and sockets, and want one impact driver that takes both hex bits and 1/2 in sockets.
