From the manufacturer

Bosch HDH181X-01 18-Volt 1/2-Inch Hammer Drill/Driver

The Bosch HDH181X-01 18-Volt Brute Tough 1/2-Inch Hammer Drill/Driver easily handles the toughest materials, from concrete to wood, with its Open-Frame Four-Pole motor and all-metal gearbox that provides 750 ft.-lbs. of torque. This hammer drill/driver provides remarkable operation in a tool that is simple and manageable. It features Active Response Technology, an industry first that diminishes the risk of dangerous kickback during high torque applications.

Includes

(1) 18-Volt 1/2-Inch Hammer Drill/Driver, (2) 18-Volt Lithium-Ion FatPack Batteries, (1) Charger, (1) Auxiliary Handle, (1) Double-Sided Philips Drive Bit, (1) Carrying Bag

Specifications

  • Chuck Design: Keyless
  • Chuck Size: 1/2-Inch
  • Clutch Settings: 25+1
  • Maximum Torque: 752 ft-lbs
  • No Load BPM: 0-27,500
  • No Load RPM: 0-440/0-1,850

Active Response Technology

The Bosch HDH181X-01 features Active Response Technology, which is an integrated acceleration sensor that limits the tool's rotation by detecting sudden movements and cutting off the motor. This mitigates the risk of kickback during high torque applications with little dropoff in performance. The reconfigured gearbox and clutch produces a maximum of 750 in.-lbs. of torque, with plenty of thrust provided by a Four-Pole Open-Frame motor. The 25+1 clutch settings and a variable-speed trigger help the operator supply the right amount of torque for the task. The tool has a two-speed system – one for screw driving (440 rpm) and one adjusted for drilling (1,850 rpm).

Better Control with Longer Side Handle

The side handle on the stalwart hammer drill/driver was redesigned with greater length, and the tongue-and-groove interface locks in to avoid slippage. The handle pivots to 23 positions without having to remove it from the drill/driver. The slim soft-grip handle provides user comfort and reduces fatigue. The tool comes with a single-sleeve, metal, keyless 1/2-inch auto-lock chuck for one-handed bit changes. LEDs provide illumination for darkened or enclosed areas.

Exclusive Durashield Housing

The Brute Tough drill/driver stands up to wear, tear and abuse on the jobsite because of the Durashield housing and an all metal gearbox. An ABS/nylon composite, Durashield gives the housing flexibility on impact; it was designed and tested to endure 25 drops from 12 feet high onto solid concrete, so it isn't standard-issue plastic housing found on other tools.

Built Smart

Bosch Cordless Tools bring you portable power backed by relentless innovation: Active Response Technology for torque safety, the industry's first 6.0 Ah battery, 2-in-1 Socket Ready impact drivers, pioneering wireless charging and industry-leading warranty and service, ProVantage. Outperform every day, every job.

Product Description

The Bosch HDH181X 18-Volt Brute Tough Hammer Drill/Driver now features Active Response Technology, an industry first that reduces the risk of dangerous kickback during high torque applications without compromising performance. Active Response Technology uses electronic motor control to reduce the risk of harmful torque reactions in bind-up situations. An integrated acceleration sensor limits the tool's rotation by detecting sudden movements and cutting off the motor to stop the tool. Feel more in control with the redesigned auxiliary handle. This handle is longer than previous versions and adjustable to 23 positions without having to remove it from the tool. A tongue-and-groove locking structure helps prevent slipping and increases control during use, while the 1/2-Inch metal chuck delivers a high clamping force. Tackle even the toughest drilling and driving applications with 750 in-lbs of torque from the 4-pole open frame motor. Select between 2 speeds and 25 clutch settings to optimize available torque for precise screw driving and improved drilling speed. Built to be Brute Tough, the HDH181X features exclusive Durashield housing and an all metal gearbox and is capable of surviving 25 drops from 12 feet high onto solid concrete. Bosch electronic motor and cell protection help prevent overheating and overloading - which extends tool life, runtime, and increases battery lifetime by more than 400%. For optimum results, pair this tool with Bosch's next generation BAT620 4.0 Ah or BAT612 2.0 Ah 18-Volt lithium-ion batteries, which combine greater cell energy density for up to 65 percent longer runtime and advanced CoolPack technology for up to 100 percent more recharge-life. The HDH181X-01 includes two 18-Volt 4.0Ah batteries, a belt clip and a charger.

5.0 out of 5 stars Superb drill
Reviewed in the United States on August 23, 2017
Verified Purchase
This is a superb drill. It is powerful, it toggles easily between regular and hammer-drill settings, and the battery lasts reasonably long. The high torque/low speed setting allows for slow, careful drilling, and the high speed setting is very fast. The battery charges quickly, and with two of them, you should always have power. No kickbacks yet, so that safety feature is working.

The battery is a bit heavy, but the equilibrium of it with the drill is good.

It is one of the more expensive drills in this class, but I would buy it again.

What can I say. Bosch just gets better and better. And they do withstand the fall test! Not an intentional event but it survived. Good battery life, great multi featured drill, works every bit as advertised and then some. Caution, a real wrist twister if you are not aware of or do not respect its power. With a 3.5" hole saw it will wrap you up!

4.0 out of 5 stars A lot of drill for an amateur, DOES NOT INCLUDE BITS
Reviewed in the United States on March 29, 2015
Vine Customer Review of Free Product( What's this? )
There are probably a few different kinds of drill customers out there. There is the professional driller, construction or contracting sort of person. Then there is the amateur handyman, the kind with a shed and various projects in the works. Then there are people like me - persons who live in a condo in a city, who don't do a lot of serious carpentry, who need a drill once or twice a year to put up a sliding lock or redo a door knob or attach fasteners to a picture frame.

So for me, my questions are: how easy is it to use, and how long do the batteries retain a charge (on a months scale, not a days or weeks scale).

I was satisfied on both counts. First, a caveat: THIS DRILL SET COMES WITH NO BITS. This is very important if you are in the third of the aforementioned categories. You'd better have your own bits, whether from a previous drill or some sort of stand-alone set. Luckily for me, I had my old drill and its bits. They slotted in just fine. But after that hiccup, I was pleased that the battery packs have a status indicator, retain a charge for a nice long time (mine still had juice out of the box), come in a pair with a nice charger, and are "vented" to encourage longer life.

In use, this drill generates a lot of torque. I can't imagine anything really that would provide insurmountable resistance for the motor. Your bit will break or your battery will drain before this drill will get stuck. I was able to power through a very tough picture frame that I could not hammer a guide nail into, it was so dense and hard. The drill made easy work of it. the trigger provides a very nice analog sensitivity, ramping up the speed very smoothly as you press harder.I also really like the LED "headlight" that activates when you pull the trigger. It made seeing where I was drilling an easy matter.

The drill comes with a very nice cloth case that zips up tight, though it is a bit lacking in terms of inserts to keep items stationary.

All in all, I think this is probably a heavier duty drill than most amateur once-a-year drillers might need, especially since it does not include bits in the box. For a dedicated handyman or a pro, this definitely seems like it would do the job, any job, and not quit long term.
