This is a very small drill! But for a 3/8" tool, it fits the hand perfectly. Although it doesn't have a speed control, it doesn't spin as fast as it would when the trigger is fully pulled due to less finger pressure on the trigger. Since it spins at high RPM, it's a relief this drill works on metal or wood.I also like how the keyless chuck works.It clamps the bit and releases easily when the cartridge is turned counterclockwise.It seems very well made out of polished aluminum and not cheap plastic so it should last a very long time.Be sure to use a few drops of air tool oil before use if you don't have an automatic oiler.
