Bosch | Concrete - Rotary Hammers | RH1255VC | SDS-Max 2 In. Combination Hammer GWG311721

The Bosch RH1255VC rotary hammer delivers 14.1 ft.-lb. of impact energy with an excellent power-to-weight ratio in a 2 in. hammer. The RH1255VC easily switches between hammer-only and rotary hammer modes, with an easily adjustable speed dial to suit any application. This rotary hammer uses Bosch’s impact system to maximize impact and vibration control in the handle to reduce strain on the operator. The SDS-Max bit system also ensures maximum energy transfer, with tool-free bit changes and automatic locking for convenience.

How The Bosch RH1255VC Combination Hammer Compares To Other Drilling And Chipping Options

Contractors evaluating how to handle both drilling and light chipping work usually face this question: should I stick with a smaller SDS-plus rotary hammer, step up to this SDS-max combination hammer for drilling and chiseling in one tool, or invest in a dedicated demolition/breaker hammer for heavier chipping work?

Here's the honest comparison:

Why The Bosch RH1255VC Combination Hammer Is Worth The Investment

This isn't just a bigger rotary hammer, it's a true combination tool that handles both precision drilling and light chiseling, giving contractors the flexibility to switch tasks without switching tools.

The RH1255VC specifically addresses the needs of contractors who need SDS-max drilling power and chipping capability in a single lightweight tool rather than carrying separate dedicated machines.

Turns Drilling And Chiseling Into A Single-Tool Job. Turbo Power delivers a torque and speed boost in hammer mode, while Vario-Lock positioning lets the chisel be rotated and locked with precision, so the same tool handles both drilling holes and light chipping work without a tool change.

Built For Comfort On All-Day Applications

• Vibration Control mitigates shock in both the hammer mechanism and the handle for better operator control
• Constant Response circuitry delivers smooth starts, precise hole placement, and constant speed even under load
• At under 27 lbs., the tool keeps an outstanding performance-to-weight ratio for extended use

Engineered For Precision And Versatility

• The SDS-max bit system allows for toolless bit changes, keeping the tool moving between tasks quickly
• Vario-Lock positioning permits rotating and locking the chisel with precision for chipping work
• A 2 in. chuck supports drilling up to 6 in. hole diameter with the right core bit

Real Savings

• One combination tool covers both drilling and light chiseling, avoiding the cost of two separate dedicated machines
• Toolless bit changes reduce downtime spent swapping accessories on the job
• The included auxiliary handle, grease tube, and carrying case mean no separate purchases are needed to get started
• Free shipping and no sales tax through Summit Forge Supply keeps the total cost down compared to buying elsewhere and paying tax and freight separately

The Bottom Line Contractors who need both precision drilling and light chipping can't rely on a single-purpose rotary hammer or a heavy dedicated breaker alone. The Bosch RH1255VC is built with Turbo Power, Vario-Lock chisel positioning, and a toolless SDS-max bit system, so it delivers real versatility in a lightweight, all-day tool. For anyone who needs to drill and chip without switching machines, this is the combination hammer built to handle it.
