Order Makita BHP454 18-Volt LXT 1/2-Inch Lithium-Ion Cordless Hammer Drill Kit

I've owned many hammer drills for my general contractor business.

The Makita BHP454 Hammer Drill is very good quality but has one major failure same as but worse than my Hitachi Hammer Drills: The key-less chuck spits out the drill bits and screw driver bits when you release the trigger.

The electric brake stops the motor quickly and the inertia of the chuck loosens the jaws and the tool drops out !!!!!!!!!!! This is a major annoyance.

I've called Makita and they do not have a keyed-Jacobs chuck as a replacement.
