The DEWALT D25333KDH SDS Plus rotary hammer kit is a 1-1/8-inch corded rotary hammer designed for concrete and masonry drilling, with an onboard dust extractor that helps you meet OSHA Table 1 compliance. Its German-engineered hammering mechanism delivers 3.5 joules of impact energy for rapid drilling, and Active Vibration Control reduces handle vibration for less user fatigue. This kit suits professional contractors, concrete finishers, and serious DIYers who drill anchors, rebar, and through-holes on a regular basis.
DEWALT D25333KDH Rotary Hammer Features
The D25333KDH has a wide optimal drilling range between 3/16 in. and 7/8 in., so a single hammer can handle common anchor and conduit holes. The factory-set clutch reduces sudden, high-torque reactions if the bit jams, protecting you and the tool. Plus, the onboard dust extractor keeps particles contained, meaning less cleanup and fewer airborne particles.
What to Do If a Bit Gets Stuck in Your D25333KDH
A stuck SDS Plus bit is usually caused by a dirty chuck, a worn bit shank, or debris inside the retention system. To release it, first unplug the hammer, then press the SDS chuck collar back toward the tool and pull the bit straight out. If it won't budge, tap the bit with a rubber mallet while the collar is held open, and keep upward pressure on the bit. Avoid using excessive force or prying, which can damage the chuck. If the bit remains stuck, the chuck may need cleaning or servicing.
D25333KDH Chuck Maintenance and Lubrication
Regular maintenance prevents stuck bits and keeps the chuck working smoothly. After each job, blow dust out of the SDS chuck using compressed air, and wipe the bit shank clean before insertion. Apply a small amount of SDS chuck grease to the bit shank and the inside of the chuck every few weeks or after heavy use. Do not lubricate the chuck collar with penetrating oil—it can attract dust and make sticking worse. If the chuck feels stiff or bits stick often, disassemble the chuck nose per the service manual and clean the retaining balls and springs.
Included in the D25333KDH Kit
The D25333KDH kit couples the hammer with an onboard dust extractor and a rugged carrying case for portability. The hammer features an electric brake, variable speed trigger, and a service indicator light, making it a durable, professional-grade choice.
