Porter-Cable 9977 Cordless Drill


PERFORMANCE RATINGS
Power 420 in-lbs - The 9977 is 20% more powerful than average and ranks in the top 20% of 14.4V-class drills for torque and power. It generates 68 in-lbs more maximum torque than the average 352 in-lbs drill in its class.
Speed
Settings
2 Settings 0-450 / 0-1,400 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
1400 RPM - This Porter-Cable 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 20 Settings - The Porter-Cable 9977 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
75 P/W - The Porter-Cable 9977 is designed with an average power-to-weight ratio that is standard for mid-range 14.4V-class cordless drills. The average P/W ratio is about 77 for cordless drills in this voltage class.  
Hammer 0-18,850 IPM - Generates a hammer impact rate that's 31% lower than average and ranks in the bottom 20% of hammer drills for IPM. It delivers 8150 less impacts per minute (IPM) than the average 27000 IPM drill.  


DURABILITY RATINGS
Gear
Case
Non-Metal Parts - Some of the Porter-Cable 9977 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 All-Metal - Drills are commonly dropped-off ladders onto concrete and the chuck often bears the brunt of the impact. An all-metal chuck with metal sleeve helps prevent damage and costly repairs.
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 - Porter-Cable'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) 8723 - 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 2 Ah - This Nickel Cadmium (NiCd) battery ranks about average for capacity and run-time with an amp-hour (Ah) rating that is considered standard for 14.4V-class batteries. The average battery capacity for this class is rated at 2.1 Ah.  
Charge
Time
60 min Universal 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 Porter-Cable 9977 that's charged and ready to go. Makes it easy to swap-out batteries during the job with minimal down-time.


CONVENIENCE RATINGS
Weight 5.6 lbs Tool Plus Battery - It is 22% heavier than average and ranks in the bottom 40% of 14.4V-class drills for higher weight. It weighs 1 lbs more than the average 4.6 lb cordless drill in this class and may increase operator fatigue.  
Length 10-3/4 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 Porter-Cable 9977 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.
