Milwaukee M18 Compact Brushless 2-Tool Kit vs Milwaukee M18 3-Tool Combo Kit

Both kits are Milwaukee M18 brushless, so the real choice is scope versus size. The 3692-22CT is the compact two-tool kit: a 5.7-inch drill and a 4.4-inch impact driver that fit overhead and tight work, with 2.0Ah batteries and a 5-year tool warranty. The 3-tool kit adds a hammer drill and a one-handed Hackzall saw, runs on larger 5.0Ah batteries, and carries a 4.7-out-of-5 rating from 326 owners, but it is heavier and bulkier. Buy the two-tool kit for tight-space drilling and driving; step up to the three-tool kit if you cut pipe, conduit or lumber and need hammer drilling in masonry.

• Choose the M18 Compact 2-Tool kit if you mostly drill and drive in tight or overhead spaces and want the lightest, most compact kit.
• Choose the M18 3-Tool kit if you also cut material and drill masonry, and want bigger batteries and a hammer drill in one case.
