DeWalt DC901KL Cordless Drill


PERFORMANCE RATINGS
Power 750 UWO - The DC901KL is 30% more powerful than average and ranks in the top 20% of 28V-36V-class drills for torque and power. It generates 170 UWO more maximum power than the average 580 UWO drill in its class.
Speed
Settings
3 Settings 0-400 / 0-1,200 / 0-1,600 RPM - Above average number of no-load speed settings that provides greater versatility in matching the correct speed range to the task. The standard for most drills is a 2-speed High and Low.
Max
Speed
1600 RPM - This DeWalt cordless drill is 7% faster than average and ranks in the top 40% of 28V-36V-class drills for maximum RPM. It can run at speeds that achieve 100 RPM more than the average 1500 RPM drill in its class.
Clutch 0 Settings - The DeWalt DC901KL has a below average number of clutch settings, but is probably still adequate for many DIY jobs. The clutch helps you to avoid stripping a screw with too much torque.  
Power
Ratio
111 P/W - The DeWalt DC901KL has an 19% higher than average power-to-weight ratio and ranks in the top 20% of efficiently designed 28V-36V-class drills. The P/W ratio is 17 higher than the 94 average ratio for this class drill.
Hammer 0-6,800 / 0-20,400 / 0-27,200 IPM - Designed with an average hammer impact rate that should provide standard performance for a mid-range hammer drill. The average hammer drill can deliver about 27000 impacts per minute (IPM).  


DURABILITY RATINGS
Gear
Case
All-Metal - The DeWalt DC901KL 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 - DeWalt'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) DC9360 - 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 2.4 Ah - This Lithium Ion (Li-Ion) battery has a 15% higher than average run-time with an amp hour (Ah) rating that ranks in the top 40% of 28V-36V-class drills. It has 0.3 Ah more capacity than the average 2.1 Ah battery in this class.
Charge
Time
60 min DeWalt Charger - Battery charge-time is about average for this class battery. If you only have one battery, or you go through multiple batteries on the job-site, charge-time is an important consideration.  
Fuel
Gauge
No Battery Fuel Gauge - Not equipped with a battery charge indicator that alerts you to remaining battery life or if the batteries are running low. Sudden battery failure during the job is a common frustration.  
Backup 2 Batteries Included - It's important to have a second back-up battery for the DeWalt DC901KL that's charged and ready to go. Makes it easy to swap-out batteries during the job with minimal down-time.


CONVENIENCE RATINGS
Weight 6.75 lbs Tool Plus Battery - It weighs about average and would be considered standard weight when compared to other 28V-36V-class drills. The average cordless drill in this voltage class weighs about 6.6 lbs.  
Length 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
No LED Light - The DeWalt DC901KL does not have an integrated LED light that Illuminates your work area. This feature is extremely useful, but is obviously not essential if you have secondary lighting available.  
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.
