The 11 AMP motor has 6.8 ft.lbs. of impact energy and can handle even the most difficult jobs.
Control of the speed at the same tim. automatically increases the motor’s power to keep it going when it’s under a lot of stress to do the most difficult jobs.
Soft start slows down the start-up reaction for better accuracy.
Changing the speed with a dial makes it easier for people to use the machine in a variety of ways.
A torque limiting clutch is designed to keep gears safe by disengaging gears if the bit gets stuck.
An overview of what this item is abou.
When you buy the Makita HR4041C 1-9/16 in. Spline-Shank Rotary Hammer Drill, it comes with a powerful 11 Amp motor that is made of field-core interlocking steel laminations. It also has a dual ball bearing armature, which helps transfer power more efficiently, and a large-surface switch. It can go from 230 to 460 RPM and 1,300 to 2,600 BPM. It has two modes for hammering alone and hammering with rotation. Soft start allows for better control and better accuracy, while sequential impact timing speeds up work.
There is a Manufacturer.
A powerful 12 amp motor, 1,350-2,750 BPM, and anti-vibration technology help make the Makita HR4041C 1-9/16-inch rotary hammer spline two times less noisy. A low level of noise (106dB) and vibration (4.5 m/s2) reduces fatigue and increases productivity for the people who use the machine. Besides precision-machined, all-metal gears that provide more power, the HR4041C also has gears that have more surface area to provide more power. Electronic speed control reduces speed loss when working in heavy applications to keep productivity at its highest level. They are great for drilling through holes and setting anchors, as well as core drilling, and many other things.
My old Makita Rotary Hammer HR3851 broke down after seven years of hard use, so I bought the HR4041C, which is the next generation. I used it a lot when I should have used a demolition hammer, but I used it instead. It can be hard to get a tool fixed or rebuilt because it can cost as much as a new tool to get it fixed. People sometimes have to look on Ebay for “new-old” stock. Time to buy something new.
After I bought the new Rotary Hammer, I took the HR3851 apart and was amazed at how well it was in general. To fix it, I need to buy a few parts that aren’t too pricey, so I’m doing it. Techs at Ereplacementparts.com can answer questions almost as soon as you ask them. They have parts for most things and can help you almost as soon as you ask them.
I bought the HR4041C and I’m happy with it. Instead of 10 Amps, 12 Amps. Until I switched from a 1/2″ bit to a 1-1/4″ bit, I didn’t know what variable speed was all about. I thought I should slow down because the diameter of the 1-1/4″ bit was bigger, so I did. The lower speed made the large drill bit work better at hammering, but it didn’t slow down the work.
It doesn’t have the switch for drill/hammer and hammer-only functions like the predecessor HR3851. The chisels and other tools that hammer only have a hex shank and no spline on the round end that goes in the drill chuck. They don’t move the drill chuck. So they didn’t need the switch after all. I couldn’t think of a reason not to go. The HR4041C is a few pounds lighter and, I think, a little shorter than the one before it. When you have to hold it at shoulder height and such, it’s nice.
The “blow-out bulb” should have come with Makita. It’s used to get the powder out of the holes that have been drilled in. I got it with the old drill. Even a little plastic tube and a lot of lung power can work for this task. If you don’t spend a lot of time putting the cord in the spaces around the drill, the case won’t close. And there’s no room for bits, chisels, and other hammer-drilling tools, so just throw yet another case in the trash and put everything in an old suitcase or duffle bag.
The HR4041C is a great tool.
