KEY STRENGTHS & WEAKNESSES
POWER The D10VG is 25% more powerful than average and ranks in the top 20% of power drills for amperage. The motor carries 1.8 amps more electrical current load than the average 7.2 amp corded drill.
SPEED This Hitachi drill is 11% faster than average and ranks in the top 40% of power drills for maximum RPM. It can run at speeds that achieve 110 RPM more than the average 1090 RPM corded drill.
WEIGHT It is 9% lighter than average and ranks in the top 40% of power drills for lower weight. It weighs 0.4 lbs less than the average 4.6 lb corded drill and should decrease operator fatigue.
CAPACITY This power drill ranks about average for wood bit capacity with a hole diameter that is considered standard for corded drills. The average wood bit capacity for corded drills is about 1" to 1-1/4".  
WARRANTY Hitachi's 5-year limited tool warranty is significantly longer than most drill manufacturers and ranks in the top 30% of drills. Longer warranties can often indicate improved durability with fewer repairs.

Capacity
Wood
1.25" Hole - This power drill ranks about average for wood bit capacity with a hole diameter that is considered standard for corded drills. The average wood bit capacity for corded drills is about 1" to 1-1/4".  
Speed 0-1200 RPM - This Hitachi drill is 11% faster than average and ranks in the top 40% of power drills for maximum RPM. It can run at speeds that achieve 110 RPM more than the average 1090 RPM corded drill.
Capacity
Steel
0.375" Hole - This power drill ranks about average for bit capacity in steel with a hole diameter that is considered standard for corded drills. The average bit capacity in steel for corded drills is 3/8".  
Power
Ratio
2.1 P/W - The Hitachi D10VG has an 32% higher than average power-to-weight ratio and ranks in the top 20% of efficiently designed power drills. The P/W ratio is 0.5 higher than the 1.6 average ratio for corded drills.
Gear
Reduction
Double - Gear systems with double reduction generally provide more torque for a given amperage. They operate more efficiently at lower speeds than single gear systems, which extends the life of the drill.


DURABILITY RATINGS
Gear
Housing
All-Metal - The Hitachi D10VG is manufactured with an all-metal gear housing that protects the transmission and prevents the drill from cracking when dropped onto hard surfaces such as concrete.
Gears Non-Metal Parts - Some of the transmission components are made of non-metal materials that are more susceptible to failure. Gears spin at high RPMs and experience large rotational forces.  
Warranty 5-Year - Hitachi's 5-year limited tool warranty is significantly longer than most drill manufacturers and ranks in the top 30% of drills. Longer warranties can often indicate improved durability with fewer repairs.


CONVENIENCE RATINGS
Weight 4.2 lbs - It is 9% lighter than average and ranks in the top 40% of power drills for lower weight. It weighs 0.4 lbs less than the average 4.6 lb corded drill and should decrease operator fatigue.
Length 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
No Spindle Lock - This power drill has a keyed chuck with superior gripping ability. Spindle lock is only applicable to keyless chucks and allows the operator to change drill bits with just one hand.  
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.
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.
