DeWalt Combination Rotary Hammer Drill D25481K 1 9 by 16 Inch SDS MAX 10.5 Amp 6 Joules (Concrete Drilling Chipping Coring Shocks Control)

DeWalt D25481K 1-9/16-Inch SDS-MAX 10.5 Amp Corded Combination Rotary Hammer Drill with SHOCKS

The DeWalt D25481K 1-9/16-Inch SDS-MAX Combination Rotary Hammer is an industrial corded concrete drilling and demolition tool engineered to produce 6 Joules (4.5 ft-lbs) of impact energy for heavy-duty masonry contractors. Powered by a 10.5-amp electric motor operating at 540 RPM and 3,150 BPM, this German-engineered hammer features an integrated mechanical clutch and SHOCKS Active Vibration Control technology to absorb internal mechanism recoil. Designed for horizontal rebar doweling, core drilling, and concrete chipping applications, this 21.22-pound rotary hammer utilizes standard SDS-MAX chuck shank accessories to penetrate reinforced concrete walls and slabs.

Best Used For:

• Concrete Rebar Doweling & Anchor Drilling: Drilling horizontal serial holes for number 4 through number 8 steel rebar dowels in foundation walls and highway slabs.
• Structural Masonry Chipping & Channeling: Raking out mortar, removing excess concrete flash, and cutting utility chases in brick, block, and concrete walls.
• Core Bit Masonry Penetration: Driving wide-diameter thin-wall carbide core bits through aggregate concrete and brick for pipe and conduit installations.

Key Performance & Safety Features

• 6 Joules (4.5 ft-lbs) Impact Energy: Heavy-duty electropneumatic hammer mechanism generates high impact force for rapid concrete penetration.
• SHOCKS Active Vibration Control: Internal mechanical dampening system isolates handles from motor oscillation to reduce operator fatigue.
• 10.5-Amp High-Output Motor: Heavy-duty motor produces 3,150 BPM and 540 RPM for sustained concrete drilling speeds.
• Integral Safety Mechanical Clutch: Internal slip clutch disengages drive gears instantly during bit binding to protect operators from sudden rotational torque reaction.
• SDS-MAX Industrial Chuck System: Quick-change SDS-MAX bit holder secures large shank chisels and concrete drill bits against severe impact vibration.
• Ergonomic Overhead & Wall Balance: Lightweight 21.22 lb weight distribution provides optimal leverage for horizontal wall doweling and overhead work.

Technical Specifications

Pro-Tip: Lightly coat your SDS-MAX bit shanks with high-temperature grease before inserting them into the hammer holder to prevent dust ingress and reduce wear on the locking drive splines.
