Panasonic EY7440LN2L Cordless Drill


PERFORMANCE RATINGS
Power 390 in-lbs - The EY7440LN2L is 11% more powerful than average and ranks in the top 40% of 14.4V-class drills for torque and power. It generates 38 in-lbs more maximum torque than the average 352 in-lbs drill in its class.
Speed
Settings
2 Settings 60-400 / 200-1,350 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
1350 RPM - This Panasonic cordless drill has about average speed with a max RPM comparable with standard 14.4V-class drills. The average cordless drill in this class runs at speeds up to 1459 RPM.  
Clutch 18 Settings - The Panasonic EY7440LN2L 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 Panasonic EY7440LN2L has an 45% higher than average power-to-weight ratio and ranks in the top 20% of efficiently designed 14.4V-class drills. The P/W ratio is 34 higher than the 77 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 Panasonic EY7440LN2L 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 1-Year - Panasonic's 1-year limited tool warranty is shorter than the cordless drill industry standard but is typical for many manufacturers. Shorter warranties can sometimes be an indicator of lower quality and reliability.  


BATTERY RATINGS
Type Lithium Ion (Li-Ion) EY9L40B - 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 43% higher than average run-time with an amp hour (Ah) rating that ranks in the top 20% of 14.4V-class drills. It has 0.9 Ah more capacity than the average 2.1 Ah battery in this class.
Charge
Time
50 min EY0L80B 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 Panasonic EY7440LN2L 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 24% lighter than average and ranks in the top 20% of 14.4V-class drills for lower weight. It weighs 1.1 lbs less than the average 4.6 lb cordless drill in this class and should decrease operator fatigue.
Length 7-1/2 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 Panasonic EY7440LN2L 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
Integrated Belt Hook - Includes a belt hook or clip that allows you to temporarily hang the drill from your belt or a ladder while you're performing other job tasks. Helps prevent dropped and damaged drills.
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.
