Bosch DDH181-01 Cordless Drill


PERFORMANCE RATINGS
Power 700 in-lbs - The DDH181-01 is 50% more powerful than average and ranks in the top 20% of 18V-class drills for torque and power. It generates 232 in-lbs more maximum torque than the average 468 in-lbs drill in its class.
Speed
Settings
2 Settings 0-380 / 0-1,600 RPM - Fitted with both Low and High speed settings that come standard on most cordless drills. Speed selection is an important feature to match drilling or driving RPM to each unique job.
Max
Speed
1600 RPM - This Bosch cordless drill has about average speed with a max RPM comparable with standard 18V-class drills. The average cordless drill in this class runs at speeds up to 1584 RPM.  
Clutch 26 Settings - The Bosch DDH181-01 has an above average number of clutch settings that provide a wide range of protection for almost any job. The clutch acts like a brake and helps prevent stripping screws.
Power
Ratio
115 P/W - The Bosch DDH181-01 has an 15% higher than average power-to-weight ratio and ranks in the top 40% of efficiently designed 18V-class drills. The P/W ratio is 15 higher than the 100 average ratio for this class drill.
Hammer This cordless drill is not equipped with a hammer function that can deliver several thousand impacts per minute. Hammer drill drivers are usually a little heavier and costlier, but they are effective on tougher jobs such as drilling into concrete.  


DURABILITY RATINGS
Gear
Case
All-Metal - The Bosch DDH181-01 transmission has all-metal gears that provide superior durability compared to nylon gears found in many drills. Gears spin at high RPMs and are susceptible to material break-down.
Chuck All-Metal - Drills are commonly dropped-off ladders onto concrete and the chuck often bears the brunt of the impact. An all-metal chuck with metal sleeve helps prevent damage and costly repairs.
Motor No Brush Access - The entire drill usually has to be taken apart in order to access the motor brushes. Motor brushes wear-out and must be replaced periodically, but repair costs can sometimes be prohibitive.  
Warranty 3-Year - Bosch's 3-year limited tool warranty is a little longer than average for the cordless drill industry where the standard is about 2-3 years. Longer warranties can often indicate improved durability with fewer repairs.


BATTERY RATINGS
Type Lithium Ion (Li-Ion) HC FatPack BAT619G - Newer technology rechargeable battery that provides higher capacity and longer run-time with less weight, but are more expensive than the older NiCd and NiMH batteries.
Capacity 3 Ah - This Lithium Ion (Li-Ion) battery has a 37% higher than average run-time with an amp hour (Ah) rating that ranks in the top 20% of 18V-class drills. It has 0.8 Ah more capacity than the average 2.2 Ah battery in this class.
Charge
Time
30 min Bosch Charger - Battery charge-time is quicker than average. Nice feature for those times when you don't have a charged replacement battery ready to go and you're in the middle of a job.
Fuel
Gauge
Battery Fuel Gauge - Equipped with an on-board battery charge indicator that keeps you aware of the remaining battery life. Great feature that prevents frustration - no more dead battery surprises.
Backup 2 Batteries Included - It's important to have a second back-up battery for the Bosch DDH181-01 that's charged and ready to go. Makes it easy to swap-out batteries during the job with minimal down-time.


CONVENIENCE RATINGS
Weight 6.1 lbs Tool Plus Battery - It is 30% heavier than average and ranks in the bottom 20% of 18V-class drills for higher weight. It weighs 1.4 lbs more than the average 4.7 lb cordless drill in this class and may increase operator fatigue.  
Length 8.3 in - Cordless drill length is a personal preference, but shorter is generally better to help you in close quarters such as under a sink, or drilling in-between studs. Torque is harder to handle if the drill is too short though.  
Spindle
Lock
One-Hand Bit Change - This single-sleeve chuck has auto spindle lock. The drill bit can be changed with only one hand by simply spinning the chuck open to release the bit, and counter-spinning it to tighten.
LED
Light
Integrated LED Light - The Bosch DDH181-01 illuminates your work area and allows you to clearly see your bit position and depth while you're drilling or driving. Great feature that's now available on many cordless drills.
Belt
Hook
No Belt Hook - There is no provision to hang the drill on your belt and free-up both hands to perform other tasks. You may be able to purchase a separate belt clip that can be attached to the drill.  
Side
Handle
Side Handle Included - Higher torque levels can cause injury if a bit suddenly binds or the drill slips. A side handle is essential to handle more powerful drills and provides additional stability and control.
Bubble
Level
No Bubble Level - This feature is only available on a few drills and can be helpful in situations where precision holes are critical for alignment. Most projects can be performed with just visual sighting.  
Keyless Keyless Chuck - Nearly all cordless drills are now equipped with keyless chucks that can be tightened with both hands (double-sleeve) or just one hand (single-sleeve) without the use of a key.
VSR VSR - Most cordless drills are equipped with variable speed capability that can be controlled with simple trigger pressure. Reverse is usually performed with the push of a side-to-side button.
