Bosch 10x PRO Metal HSS-G Twist Drill Bit Standard Length (for Non-ferrous metals, Steel, Ø 4,00 mm, Professional Accessory Rotary Drill/Drivers)

Good value for the money

Sharp drill bits that retain their sharpness - so far. The larger sizes have particularly long helix tracks so are good at removing the drilled wood.

Very sharp, better than the cheaper bulk drill bits.Time will tell if these last plus 5mm is my main size so having 10 is good. Hopefully they don't start to snap ...So far so good...

Sharp and long lasting cutting edge

Hi. I cannot as yet comment on the quality of this drill set. But, for some reason my set is missing the 1mm drill. I notice others have reported this problem with the product. I wonder if this 1 mm drill falls out of it's holder, can anyone confirm this? Gave three stars because I suspect it's at least a 3 star product. EDIT: I contacted Bosch by email, but not got a response so I have sent back item and got a prompt refund by Amazon. Odd that quite a few buyers report the missing of the 1mm drill bit. Bosch's fault, not Amazon's.

I needed some drill bits to replace some that got broken by family members (who shall remain nameless) during a recent DIY project, so I purchased a box of these expecting them to get trashed in the same way and they haven't broken one yet. Good quality drills and a reasonable price, recommended.

Great drill bit that gave me the extra depth that was required.

I have quite a few Bosch drill-bits and generally they are o.k but these are absolutely terrible. Two snapped without much pressure and the rest just cannot go through anything thicker than a couple of mm. I have some old Piranha ones which I had lost but have since found. They have been used countless times and work. These are not fit for purpose. For those giving 5* reviews. What are you using them on?? I don't like leaving poor reviews but these are worthy of no stars......
