Hitachi DS18DMRPS Cordless Drill


PERFORMANCE RATINGS
Power 550 in-lbs - The DS18DMRPS is 18% more powerful than average and ranks in the top 40% of 18V-class drills for torque and power. It generates 82 in-lbs more maximum torque than the average 468 in-lbs drill in its class.
Speed
Settings
2 Settings 0-400 / 0-1,600 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
1600 RPM - This Hitachi 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 22 Settings - The Hitachi DS18DMRPS 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
100 P/W - The Hitachi DS18DMRPS is designed with an average power-to-weight ratio that is standard for mid-range 18V-class cordless drills. The average P/W ratio is about 100 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.  


DURABILITY RATINGS
Gear
Case
Non-Metal Parts - Some of the Hitachi DS18DMRPS 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 External Access Brushes - Motor brushes must be replaced periodically and external access makes the job a much easier DIY task. No need to take your drill into the repair shop for complete disassembly.
Warranty 5-Year - Hitachi'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) 322881 - 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 18V-class batteries. The average battery capacity for this class is rated at 2.2 amp-hours.  
Charge
Time
30 min Hitachi Charger - Battery charge-time is quicker than average. Nice feature for those times when you don't have a charged replacement battery ready to go and you're in the middle of a job.
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 Hitachi DS18DMRPS that's charged and ready to go. Makes it easy to swap-out batteries during the job with minimal down-time.


CONVENIENCE RATINGS
Weight 5.5 lbs Tool Plus Battery - It is 18% heavier than average and ranks in the bottom 40% of 18V-class drills for higher weight. It weighs 0.8 lbs more than the average 4.7 lb cordless drill in this class and may increase operator fatigue.  
Length 9.33 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 Hitachi DS18DMRPS 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
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.
