Product Description

Featuring Durashield housing to guard against wear and tear, the 36618-02 utilizes an 18-volt Litheon battery, which provides 35% more runtime and two times the recharge cycles of its competitors.

The 36618-02 Litheon Drill/Driver offers:
  • 18-volt Litheon batteries for long-lasting performance.
  • Up to 1,600 RPM and 500 in./lbs. of torque.
  • 20 clutch settings and a variable-speed trigger for versatility.
  • One-handed bit changes.

Even though this tool comes with 2 Slim Packs, you can purchase a Fat Pack separately and get more run time--2.6 Ah vs. 1.3 Ah with the Slim Pack. No other company provides this option.

18-Volt Litheon Batteries for Maximum Runtime and Manageability
The 36618-02 utilizes state-of-art lithium-ion battery technology and Bosch's proprietary ECP (Electronic Cell Protection) system to provide maximum cycle life, minimum self-discharge, and no memory-effect. Best of all, Litheon batteries will fully charge in 30 minutes and will be at 85% capacity in just 15 minutes.

Handle grip with finger support provides maximum control. View larger.
Up to one pound lighter than comparable 18-volt NiCad drills/drivers, the 36618-02 won't weigh you down. It's ideal for a wide range of drilling and fastening jobs, from hanging curtains to building a deck; from making automotive repairs to installing cabinetry.

Unique, Flexible Power System
Like all tools in Bosch's 18-Volt line, this drill/driver can be used with either a 1.3-Ah BAT609 Slim Pack battery (two included) or a 2.6-Ah BAT318 Fat Pack. If you're looking for a lighter-weight option, the Slim Pack is the perfect choice. If longer runtime is what you need, the Fat Pack will do the job. Bosch is the only power tool manufacturer that provides this option.

Fast Speeds, High Torque, and Durable Construction for Reliable Results
The 36618-02 works at speeds up to 1,600 RPM and provides 500 in./lbs. of torque. Durashield housing, unibody construction, and a steel-reinforced collar help you withstand real-world conditions, like temperature extremes, rain, dirt, debris, and drops.

The 36618-02's Durashield Housing is constructed with ABS/Nylon composite, which makes the housing flexible and impenetrable. Unlike competitive tools, which use a conventional plastic housing, Durashield will not crack and can easily withstand 10-foot drops.

This tool also features unique unibody construction with three steel straps that keep the motor, gears, and clutch together. This ensures that the gears never separate from the motor, and it keeps the drill functioning even after drops.

Additionally, the 36618-02 boasts an exclusive steel-reinforced collar that protects the nose of the drill. It provides extra reinforcement in the event of drops on the chuck and prevents the chuck from bending or breaking off.

Easy Bit Changes and Balanced Design for Utmost Control
The 36618-02 comes complete with a single-sleeve 1/2-inch chuck for one-handed bit changes, as well as increased drill-bit capacity for versatility. And for maximum control, comfort, and balance, the tool boasts a newly designed handle-grip with finger support.

Smart Features for Easy Use
20 clutch settings and a variable-speed trigger help you match the best speed to the job, so you can achieve precise results. At the same time, the 36618-02's ergonomic design provides optimum comfort and control. And for even greater convenience, LEDs provide illumination when you are working in dark or enclosed areas.

ProVantage Guarantee
The 36618-02 comes with the ProVantage three-year protection plan, which guarantees two years of battery protection and one year of tool protection. Under this plan, you can receive two years of free battery replacements, tool replacement for one year, and a free tool repair package for the second and third years.

By D. Hansen on January 17, 2009
I purchased this drill along with a Makita BDF452 and gave both a workout in my garage. My test used 2"x6" pressure treated lumber. My goal was to test power, battery endurance and comfort of use. With both drills, I drilled qty (10) 1" spade bit holes, qty (20) 3/8" bit holes and sunk qty (75) 2" drywall screws. My hand and arm were tired so I quit, but suffice it to say, neither drill quit, so I called battery endurance test a tie. I believe the Bosch had slightly more power and speed, but the Makita had plenty of both for my needs. Both drills gave your arm a good twist when the spade bit would catch and hold. In a close race, I declared the Bosch the winner in power category. The Makita was clearly a more comfortable drill to use. It fit my hand well and the trigger was easy to use. The Bosch handle is configured at a bit of an angle and while using the spade bit the back of the drill seemed to press into my hand. Also, during use my finger naturally moved to the bottom of the trigger and it became a bit uncomfortable. Both drills are very well built and neither got hot during my tests. At the end of the day I preferred the Makita because it was slightly smaller (about 3/4" shorter) and clearly had a more comfortable grip position during use.

Great drill! I am Contractor and currently own the 36v Bosch litheon drill (Dewalt XRP before that), but I got tired of using it for smaller projects like hanging doors and installing cabinets due to it's bulky size and weight. I now find myself using this drill for everything. It has an excellent power to weight ratio and is very smooth/refined. I have the slim pack batteries and they hold a good charge. I will still keep the 36V around but it may end up collecting dust. I have only owned the 18v for two weeks now so I can't comment on it's long term reliability, but I have used it for sinking numerous 3" deckmates into framing lumber, speedbores, small holesaws, backerboard screws, and other fasteners. I can't comment on it's mixing ability (mortar and other cement mixtures), but that's what electric corded drills are for. As an every day user, I am very happy with this purchase.

Used it to build 4 picnic tables from Rockler plans in a college class. Four work crews, 3 days, hundred of screws in green treated lumber, one charge. Amazing torque, did not need to recharge. Students are Construction management majors and future shop teachers. They were impressed, as was I. Preschoolers came and helped assemble the tables (donated to their preschool) and the clutch worked well to allow the screw to be driven to the correct depth. I love this drill. Oh, and the light is sweet when working in dim areas.

Super tool! I usually don't brand-buy, but my garage seems to be collecting a lot of blue-green and red tools. I have a Bosch RO sander and jigsaw now, and I think they are both top notch. This cordless drill fits right in with the other quality tools. Background: I use this tool for light to heavy work (fine woodworking, drywall, rough carpentry, make holes in 4x4 joists with spade bits to run electrical cable).

The drill is very slender compared to my old (got it three years ago) cordless Craftsman. I can drill in tighter spaces now without having to use my 90 degree attachment. The size reduction also means a lighter tool, which is very deceptive; this drill has some serious power. Nothing like a corded drill but still... The power of the 18 volt is impressive to say the least. I love the 30-minute charge time for the baterries. I fully anticipate solely using this drill thoughout an entire day-long project.

The ratcheting lock it GREAT! I put in a bit and tighten it down with a ratchet lock. This feature has given me the utmost confidence that a bit will never again slip again.

The price is kind of up there compared to competitors, but you get a whole lot of quality with this purchase. Highly recommend!

I purchased the Bosch to replace another 18v that stopped working. I was impressed with the balance, lightweight (compaired to a NiCa) and the exceptional sensitivity of the variable speed contol. I also like the led light under the A good quality product. Negative features are a poorly designed bit holder (it doesn't work!) and no belt hook. Other than that a great quality tool

I bought this to replace a 5 year old Makita with Nimh batteries. I liked the Makita, but I needed new batteries and at $90 each, this whole new Bosch setup was cheaper. I really like it. With the new lithium ion battery technology, it is much lighter than my old Makita. Plus this one has a single collar auto-locking chuck, making one handed bit changes easier. It has good power and torque, but also enough finesse to drive small screws slowly. I like it so much that I ordered the matching Bosch impact driver. The only knock on it, and the reason it gets 4 stars, is that it comes with two slim batteries that don't have the greatest run time. Fat 2.6 amp hour batteries are available separately. I plan to pick up the larger battery pack for the impact driver.

Bought this drill after returning the 14.4V Black and Decker. My first thought was to spend about $70-$80 for a drill. I quickly learned while constructing a wooden swing set that the Black and Deck was not a very good tool and went back and spent an extra $60 bucks to get this tool. The difference was amazing, this drill just feels stronger and better made (the BD felt like it was made of plastic and this one felt like it was made of metal). Grat power and torque, nice size, quick bit changes--plus the chuck locks with a "click" so you know its locked (the BD chuck couldn't even keep the drill bits in place). All in all I was very happy with this purchase, its the type of tool you just hold and know its a quality tool. BUY this drill!!
