Milwaukee Rotary Hammer 5321-21, 1-1/2" Spline Drive Rotary Hammer
Milwaukee 5321-21 patented vibration isolation system greatly reduces operator fatigue by absorbing the hammering
action with floating handles.

Milwaukee Rotary Hammer 5321-21, 1-1/2" Spline Drive Rotary Hammer
The new Milwaukee 5321-21 1-1/2 in. rotary hammers deliver outstanding drilling performance in a lightweight
package. Milwaukee's patented vibration isolation system greatly reduces operator fatigue by absorbing the
hammering action with floating handles. A soft-shift stop rotation knob permits the operator to smoothly change from
hammer-with-rotation mode to the hammer-only mode. The Milwaukee 5321-21 offers a 11.0 amp motor combined with
an electronic feedback control circuit allows a full 6 inch thin wall Core Bit to be driven through 5000 PSI concrete
without bogging down. The on-off switch is coupled with a speed dial so that the speed and blow energy can be
correctly matched to the application or accessory. The bit locking system features one-handed click-in bit insertion.
The Quik-Lok® cord allows for fast twist-off, twist-on cord replacement. A pre-set clutch protects against sudden motor
overloads. The service reminder light indicates when the carbon brushes will soon need to be replaced. This versatile
tool can be used for drilling up to 1-1/2 inch holes in concrete with Spline Drive Bits, larger holes in concrete with Core
Bits or the LHS system, or used for chipping, chiseling and demolition.
