The Hilti is well worth the money! I didn't go for the larger hilti 36v, as I thought that the rotary stop just added extra weight and seeing as I do alot of chopping out thought it was best to find a lightweight corded sds so I didn't need to worry about the battery crashing at the wrong time. I found the TE-7 really well balanced and reasonably light for a 750w drill. In the year and a half i've had my gear only one thing went wrong one of the batteries, it got an electronics fault on it about 14 months in, told Hilti in the morning they sent UPS for it that afternoon from site. it was back with me in three working days with one new battery no questions asked and they serviced the drill at the same time, Brilliant service. I've also got their chasing machine, 4.5in angle grinder, 14.4v lith drill driver and vacuum cleaner all are great. I bought them all in my first year of trading got to claim back 40% worth of tax credit on them all, though my accountant has just told me last meeting that the rules have changed this year and now you get to claim back £55000 tax credit for start up costs. Sorry for long post and hijacking the thread and yes I am a tool nut, hope this helped Jack1307. cheers
