DeWalt DC742KA Cordless Drill


PERFORMANCE RATINGS
Power 200 UWO - The DC742KA generates about average power and torque when compared to other 12V-class cordless drills. The average cordless drill in this class can generate up to 239 UWO.  
Speed
Settings
2 Settings 0-400 / 0-1450 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
1450 RPM - This DeWalt cordless drill is 16% faster than average and ranks in the top 20% of 12V-class drills for maximum RPM. It can run at speeds that achieve 197 RPM more than the average 1253 RPM drill in its class.
Clutch 17 Settings - The DeWalt DC742KA 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
53 P/W - The DeWalt DC742KA power-to-weight ratio is 29% lower than average and ranks in the bottom 40% of 12V-class drills. The P/W ratio is 21 lower than the 74 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
Non-Metal Parts - Some of the DeWalt DC742KA 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) Battery - 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 1.2 Ah - This Nickel Cadmium (NiCd) battery has a 8% lower than average run-time with an amp-hour (Ah) rating that ranks in the bottom 40% of 12V-class drills. It has 0.1 Ah less capacity than the average 1.3 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 DC742KA that's charged and ready to go. Makes it easy to swap-out batteries during the job with minimal down-time.


CONVENIENCE RATINGS
Weight 3.8 lbs Tool Plus Battery - It weighs about average and would be considered standard weight when compared to other 12V-class drills. The average cordless drill in this voltage class weighs about 3.4 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
Integrated LED Light - The DeWalt DC742KA 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
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.
