Panasonic EY6450GQKW Cordless Drill


PERFORMANCE RATINGS
Power 442 in-lbs - The EY6450GQKW generates about average power and torque when compared to other 18V-class cordless drills. The average cordless drill in this class can generate up to 468 in-lbs of maximum torque.  
Speed
Settings
2 Settings 70-430 / 240-1,500 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
1500 RPM - This Panasonic 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 15 Settings - The Panasonic EY6450GQKW 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
78 P/W - The Panasonic EY6450GQKW power-to-weight ratio is 22% lower than average and ranks in the bottom 40% of 18V-class drills. The P/W ratio is 22 lower 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 Panasonic EY6450GQKW 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 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 Nickel-Metal Hydride (NiMH) Battery - Older rechargeable technology with higher capacity than NiCd batteries, but shorter shelf life. Inferior to Lithium Ion due to heavier weight and shorter run-times.  
Capacity 3.5 Ah - This Nickel-Metal Hydride (NiMH) battery has a 60% higher than average run-time with an amp hour (Ah) rating that ranks in the top 20% of 18V-class drills. It has 1.3 Ah more capacity than the average 2.2 Ah battery in this class.
Charge
Time
65 min EY0110B Charger - Battery charge-time is longer than average for this class battery. If you are a serious DIYer or professional, it's important to have at least two batteries with one always charged for back-up.  
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 EY6450GQKW that's charged and ready to go. Makes it easy to swap-out batteries during the job with minimal down-time.


CONVENIENCE RATINGS
Weight 5.7 lbs Tool Plus Battery - It is 22% heavier than average and ranks in the bottom 40% of 18V-class drills for higher weight. It weighs 1 lbs more than the average 4.7 lb cordless drill in this class and may increase operator fatigue.  
Length 9-13/16 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 Panasonic EY6450GQKW 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.
