Bosch 18V Cordless Combo Kit GXL18V-233B25 Hammer Drill Freak Impact Driver (490 In-Lbs Torque 1/4 Hex 1/2 Square Anvil Two 4.0Ah Batteries Bag)

Bosch GXL18V-233B25 18V Brushless 2-Tool Cordless Combo Kit with Freak Impact Driver & Hammer Drill

The Bosch GXL18V-233B25 18V brushless 2-tool cordless combo kit drives structural fasteners, drills tough masonry foundations, sets mechanical anchors, and runs continuous lag screws across demanding residential and commercial jobsites. Featuring the GDX18V-1800 Freak two-in-one bit and socket impact driver delivering 1,800 inch-pounds of torque with an integrated 1/4-inch quick-change hex shank and 1/2-inch square drive anvil, paired alongside the GSB18V-490 1/2-inch hammer drill generating 490 inch-pounds of torque and 22,000 BPM, this versatile pairing handles heavy construction tasks without adapter swaps. Powered by two CORE18V 4.0 Ah high-power lithium-ion batteries with 21700 cell architecture, maintenance-free EC brushless motors, and all-metal chuck assemblies, it provides electrical contractors, commercial framers, and HVAC installers with maximum runtime, compact balance, and thermal overload protection during heavy daily fastening operations.

Best Used For:

• Structural Fastening and Socket Driving: Installing 1/2-inch impact sockets directly onto the Freak square anvil to drive heavy lag screws, ledger board fasteners, and timber structural bolts without socket adapters.
• Masonry and Concrete Anchor Drilling: Bores clean pilot holes in poured concrete slabs, cinder blocks, and brickwork up to 1/2-inch diameter utilizing the high-speed hammer action mode.
• Commercial MEP and Electrical Rough-Ins: Assembling heavy strut channel trapeze brackets, mounting electrical panels, and driving multi-material self-tapping metal framing screws.

Key Performance & Safety Features

• Freak 2-in-1 Dual Bit and Socket Anvil: Integrates a 1/4" quick-release hex shank receiver inside a 1/2" square drive anvil to eliminate fragile socket drive adapters.
• High-Efficiency EC Brushless Motors: Delivers increased motor efficiency, extended battery runtime, and eliminates carbon brush maintenance across both tools.
• Robust All-Metal Ratcheting Chuck: Heavy-duty 1/2" metal keyless chuck on the hammer drill provides superior bit retention and resists jaw slippage under high torque loads.
• 20+1 Position Mechanical Clutch: Precision adjustable clutch settings prevent screw head stripping, fastener snapping, and damage to sensitive finishing materials.
• Next-Generation CORE18V® Lithium-Ion Cells: Utilizes 21700 battery cell technology to deliver optimized power density and enhanced thermal dissipation for prolonged tool performance.
• Electronic Motor & Cell Protection (EMP/ECP): Protects motor stators and battery cells against severe overloads, dangerous overheating, and deep discharge conditions.

Technical Specifications

Pro-Tip: When shifting between driving heavy 1/2-inch structural lag bolts and standard 1/4-inch hex framing screws on the Freak driver, avoid using standard socket hex adapters; snap 1/2-inch impact sockets directly over the outer friction anvil to eliminate adapter breakage and maximize rotational torque transfer.
