Makita 1-9/16" Rotary Hammer, Accepts Spline Bits - HR4041C

Makita 1-9/16" Rotary Hammer, Accepts Spline Bits - HR4041C 

The Makita HR4041C 1-9/16 in. Spline-Shank Rotary Hammer Drill features a powerful 11 Amp motor engineered with field-core interlocking steel laminations, a dual ball-bearing armature and a large-surface commutator for an efficient transfer of power. It delivers up to 230 - 460 RPM and 1,300 - 2,600 BPM and has 2 modes for hammering only and hammering with rotation. Soft-start functionality facilitates control and improved accuracy, while sequential impact timing promotes faster work. The Makita HR4041C 1-9/16-inch rotary hammer spline features a powerful 12 amp motor, 1,350-2,750 BPM, and anti-vibration technology for two times less vibration. A low noise level (106dB) and vibration (4.5 m/s2) reduces operator fatigue and increases productivity. The HR4041C also features precision-machined, all-metal gears with more surface contact for more power. Electronic speed control minimizes speed loss when working in heavy applications to ensure maximum productivity. Ideal for drilling through holes, setting anchors, core drilling, and many more applications.

Features

• Powerful 11 AMP motor delivers 6.8 ft. lbs. of impact energy to handle the most demanding applications
• Constant speed control automatically applies additional power to the motor to maintain speed under load to complete the most challenging jobs
• Soft start suppresses start-up reaction for increased accuracy
• Variable speed control dial enables user to match the speed to the application for greater versatility
• Torque limiting clutch engineered to prevent gear damage by automatically disengaging gears if the bit binds

What our Experts Think

• Heavy‑Duty Power for Demanding Jobs: Robust 11–12 amp motor delivers up to ~2,600 BPM with variable speed (230 – 460 RPM), giving strong impact energy for drilling large anchor holes and tough concrete work.

• Spline Shank Flexibility: Accepts spline‑type bits, which are ideal for heavy‑duty rotary hammer applications and offer reliable engagement and durability under load.

• Enhanced Durability & Lifespan: Constant speed control maintains performance under load and the “no hammering while idling” design reduces unnecessary wear — helping extend tool life in daily use.

• Smart Safety Features: Torque‑limiting clutch helps protect gears if the bit binds, while soft‑start improves control and accuracy during start‑up.

• Versatile 2‑Mode Operation: Switch between hammer‑only and hammer with rotation to match drilling vs chiseling requirements — useful on mixed concrete‑work tasks.

• Job‑Ready Kit: Comes with a D‑handle, side handle, depth gauge, and case — giving professionals ready‑to‑use convenience.

Maintenance Tips

• Clean Tool After Use: Wipe dust and concrete debris from the tool body, vents, and housing after every job to prevent buildup and help cooling and performance.

• Check Fasteners: Before operation, ensure the side handle and depth gauge are tight and properly positioned for stable, safe use.

• Inspect Bits & Shanks: Clean spline‑shank bits before and after use; remove debris from the bit retainer to maintain secure bit engagement and optimal drilling.

• Warm Up in Cold Conditions: If the tool hasn’t been used for a while or is cold, run it briefly without load to warm up lubrication before heavy drilling.

• Use Genuine Grease: Replace internal grease per manual guidance using Makita genuine hammer grease — overfilling or wrong grease can affect performance.

• Service by Authorized Centers: For brush wear, internal issues, or scheduled maintenance like brush replacement, use Makita authorized service with genuine parts.
