Bosch8X PRO Impact Set with Standard Bitholder and Pick and Click Index (170 x 120 mm, Professional Accessory Screwdriver, Screwdriver)

Well, being a brand that I like I thought I'd test the bits out so I did... I drove a cheap workzone 8cm screw into a block of pine full of knots and the screw want all the way in and went a further 35mm before actually spinning out. So I chiselled the screw out and it turns out the screw had actually bent 5° 32mm from the tip due to one of the larger knots so from that the pz2 tip looks like it had suffered a little but it's just the paint that has come off. No rounding or actual damage.

Poor quality, lasted about 100 screws at best, and those were only 5mm screws into softwood. Used in Dewalt impact driver.

Hasn’t broken yet

As a self employed carpenter for more than 30 years I've learnt a bit about 'bits' and these are well worth the money ,,quality.

Great
