Bosch SDS-plus® 1-1/8" Rotary Hammer

Bosch SDS-plus® 1-1/8" Rotary Hammer

The Bosch RH328VC SDS-plus® Rotary Hammer delivers professional drilling and chiseling performance in a compact, comfortable design. Built for concrete contractors, electricians, plumbers and general construction crews, it combines 2.4 ft.-lbs. of impact energy with vibration control for demanding day-to-day work.

Key Benefits

• Powerful 8.0-amp motor delivers up to 2.4 ft.-lbs. of impact energy for drilling and chiseling in concrete and masonry.

• Vibration Control in the hammer mechanism and grip helps reduce operator fatigue during extended use.

• Three operating modes provide the flexibility to drill, hammer-drill or chisel with one tool.

• Compact 12.5" body and 7.7 lb. weight provide an excellent power-to-size ratio for overhead and confined-space applications.

• Integral clutch helps protect the operator by disengaging torque transmission if the bit binds.

• Variable-speed trigger allows controlled starts and more accurate bit placement.

• Vario-Lock positioning lets the operator place a chisel in one of 12 positions for improved leverage and working angles.

• SDS-plus® tool holder provides quick bit changes and secure power transfer.

Detailed Description and Features

Professional Drilling and Chiseling Power

The Bosch RH328VC is powered by an 8.0-amp motor that produces up to 2.4 ft.-lbs. of impact energy and as many as 4,000 blows per minute. This combination provides the force needed for drilling anchor holes, creating penetrations and performing light-duty concrete and masonry removal.

Three Operating Modes

A multifunction selector allows the operator to match the tool’s operation to the job. Rotary hammer mode combines rotation and impact for concrete drilling, rotation-only mode supports standard drilling applications, and hammer-only mode allows the tool to be used with chisels and other demolition accessories.

Reduced Vibration for Longer Work Sessions

Bosch Vibration Control is built into both the hammer mechanism and grip area. This system helps limit the amount of vibration transferred to the operator, improving comfort during repetitive drilling, overhead work and extended chiseling applications.

Compact Power-to-Weight Design

At only 7.7 lbs. and 12.5" long, the RH328VC delivers strong impact performance without the bulk of a larger rotary hammer. Its compact size makes it easier to handle on ladders, overhead and in tight mechanical or utility spaces.

Improved Control and Bit Placement

The variable-speed trigger allows the operator to begin drilling slowly for accurate bit placement before increasing speed. A 360-degree auxiliary handle can be adjusted around the tool to provide a stable and comfortable grip from different working positions.

Vario-Lock Chisel Positioning

The Vario-Lock system allows a chisel to be positioned in one of 12 angles. This helps the operator maintain better leverage when removing tile, scaling concrete, cutting channels or working close to walls and other obstructions.

Integral Clutch Protection

An integral clutch disengages torque transmission when a drill bit becomes bound in the material. This helps reduce sudden tool rotation and provides greater control during demanding concrete drilling applications.

Technical Specifications

Compatibility and Recommended Use

The Bosch RH328VC is compatible with SDS-plus® drill bits, chisels and accessories. It accepts drill bits up to 1-1/8" in diameter and core bits up to 3-1/8" in diameter.
