Hello, - As soon controlled usual with Amazon (May 27) and quickly received (2 June)! This small drill series 6000, I have two that still work very well, will lead to a lapidary disk remains 180 m / m Wolfcraft. With a speed between 1500/3000 laps under 500 Watts ... great! Cost of my set (45 + 35) 80 for a result sanding almost semi-prof. - In addition, this (block) engine could also climb on my "mobile drilling Guide" and 2 "drilling Media" Wolfcraft. I assert here that the machines and made under (collar of 43 m / m) are more than adequate to good quality DIY! We will proceed with care course! PM: This small drill must actually penetrate all materials with minimal effort ... whatever: I express serious doubts for drilling shuttered concrete, vibrated kind 350 kg and / or prestressed concrete. But certainly not all ways with the 3 forests supplied with this drill ... I twist the 5 m / m "hands-free"! QED Cordially Daniel BINTHER
