I have a HR2470 Makita SDS+ drill from ITSL
http://www.its.co.uk/pd/HR2470-Maki...l-Chiselling-Action-Cap-inside-_MAKHR2470.htm
It came with a free Makita 17 Piece SDS+ Accessory Set
Whilst using one of the accessory bits (the 8mm * 120mm drill) to drill into a brick wall.
The first few holes went in fine, no issues. I then noticed the bit was jumping a lot inside, and not going in cleanly. So pointed the drill at myself and spun the drill and sure enough it had bent.
I then went to screwfix and bought this bit http://www.screwfix.com/p/erbauer-sds-plus-masonry-drill-bits-8-x-260mm/80791
Again same issue , 1st few fine then starts going crazy and upon checking it too has twisted.
So question, is the makita accessory set crap as well at the bit from screwfix....or has the sds drill somehow managed to screw up the bits?
