An absolute highlight of the machine is the wonderfully ergonomic, hard as nails biting and absolutely perfectly finished chuck from Röhm: full metal, Radialverrieglung, carbide Spannfasen - "Extra RV," who wants to be more fully informed. Since no bit also dissolves the fast screws from the feed - an experience that I was able to make about all 20 Screw holes unfortunately with the current built-in feed BHP454 (Jacobs?).
Ergonomics - although always somewhat subjective - for me anyway one of the great strengths of the device. Although only the chuck has its weight, the gear is made of metal and influenced the Schlagbohrsatz both weight and length is negative, the unit at 2.2 kg still only marginally heavier than entry-level devices, ME perfectly balanced and is therefore perfectly in the hand , This is certainly an achievement of aufzuschiebenden batteries. Sliding batteries are controversial because often rickety and less durable in professional circles. For a plug-in battery requires a thicker handle, which would not please me at least, also rattles nothing in Makitaausführung the sliding battery how long the recording then stops will be seen, certainly depends also on the treatment.
Speaking of battery: 18V 3Ah with not only provide enough fodder for the engine available, but leave - because I can agree with the previous speaker only - make arm and wrist even stronger user rather limp. And then there's - if a battery you could just - still only about half an hour break, then he is definitely back brim. As fast as the wrist is not recovered. ;-)
So I would recommend this device without limitations, the quality is significantly better than that of the much more recent two-speed model BHP454 and insofar as the BHP451 would also possibly some extra money my unconditional recommendation. I bought it after I had returned the BHP454 quality reasons virtually on the spot, and am now reconciled.
