DeWalt DW920K-2 Cordless Drill


PERFORMANCE RATINGS
Power 80 in-lbs - The DW920K-2 is 111% more powerful than average and ranks in the top 20% of Screwdriver-class drills for torque and power. It generates 42 in-lbs more maximum torque than the average 38 in-lbs drill in its class.
Speed
Settings
1 Setting 0-500 RPM - Does not include the standard low and high speed range settings that are available on most drills. Having just one setting will limit your ability to match the appropriate speed setting to a wide variety of tasks.  
Max
Speed
500 RPM - This DeWalt cordless drill has about average speed with a max RPM comparable with standard Screwdriver-class drills. The average cordless drill in this class runs at speeds up to 550 RPM.  
Clutch 21 Settings - The DeWalt DW920K-2 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
23 P/W - The DeWalt DW920K-2 power-to-weight ratio is 31% lower than average and ranks in the bottom 40% of Screwdriver-class drills. The P/W ratio is 10 lower than the 33 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.  
Electric
Brake
Electric Brake Capability - The drill stops immediately if the rotational forces surpass the clutch setting. Electric brakes help prevent the stripping or over-tightening of screws in precision work.


DURABILITY RATINGS
Gear
Case
Non-Metal Parts - Some of the DeWalt DW920K-2 transmission components are made of non-metal materials that are more susceptible to failure. Gears spin at high RPMs and experience large rotational forces.  
Chuck Plastic Sleeve - Chuck sleeves made of tough plastic materials save on weight, but they are more prone to cracking than metal sleeves. It generally won't withstand repeated drops onto hard surfaces.  
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 Nickel Cadmium (NiCd) DW9057 - The oldest and original cordless drill battery that is still found on many drills, but is significantly larger and heavier than the newer high-capacity Lithium-Ion batteries.  
Capacity 1.7 Ah - This Nickel Cadmium (NiCd) battery has a 31% higher than average run-time with an amp hour (Ah) rating that ranks in the top 40% of Screwdriver-class drills. It has 0.4 Ah more capacity than the average 1.3 Ah battery in this class.
Charge
Time
60 min 1 Hour 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 DW920K-2 that's charged and ready to go. Makes it easy to swap-out batteries during the job with minimal down-time.


CONVENIENCE RATINGS
Weight 3.5 lbs Tool Plus Battery - It is 150% heavier than average and ranks in the bottom 40% of Screwdriver-class drills for higher weight. It weighs 2.1 lbs more than the average 1.4 lb cordless drill in this class and may increase operator fatigue.  
Length 10.6 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
No LED Light - The DeWalt DW920K-2 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
No Side Handle - Side handles are a great safety feature and should be considered if you plan to drive at higher torque levels. They can help prevent injury by providing increased 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.
