Milwaukee 6547-22 Cordless Drill


PERFORMANCE RATINGS
Power 26 in-lbs - The 6547-22 generates about average power and torque when compared to other Screwdriver-class cordless drills. The average cordless drill in this class can generate up to 38 in-lbs of maximum torque.  
Speed
Settings
2 Settings 0-200 / 0-400 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
400 RPM - This Milwaukee 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 6 Settings - The Milwaukee 6547-22 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
29 P/W - The Milwaukee 6547-22 is designed with an average power-to-weight ratio that is standard for mid-range Screwdriver-class cordless drills. The average P/W ratio is about 33 for cordless drills in this voltage class.  
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
No Electric Brake - This power screwdriver has a clutch that will help prevent the stripping or over-tightening of screws, but it will not stop immediately without the aid of an electric brake.  


DURABILITY RATINGS
Gear
Case
Non-Metal Parts - Some of the Milwaukee 6547-22 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 5-Year - Milwaukee's 5-year limited tool warranty is significantly longer than most cordless drill manufacturers and ranks in the top 30% of cordless drills. Longer warranties can often indicate improved durability with fewer repairs.


BATTERY RATINGS
Type Nickel Cadmium (NiCd) 48-11-0100 - 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 1.5 Ah - This Nickel Cadmium (NiCd) battery has a 16% higher than average run-time with an amp hour (Ah) rating that ranks in the top 40% of Screwdriver-class drills. It has 0.2 Ah more capacity than the average 1.3 Ah battery in this class.
Charge
Time
60 min Milwaukee 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 Milwaukee 6547-22 that's charged and ready to go. Makes it easy to swap-out batteries during the job with minimal down-time.


CONVENIENCE RATINGS
Weight 0.9 lbs Tool Plus Battery - It is 36% lighter than average and ranks in the top 20% of Screwdriver-class drills for lower weight. It weighs 0.5 lbs less than the average 1.4 lb cordless drill in this class and should decrease operator fatigue.
Length 9-3/8 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
Hex Chuck - This power screwdriver is fitted with a standard 1/4" hex chuck. The spindle is locked in position and the drill bits can easily be inserted and removed with one hand.
LED
Light
No LED Light - The Milwaukee 6547-22 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.
