Meccion HSS Cobalt Jobber Drill Bit 10pcs 4.5mm Twist Drill Bit for Drilling Stainless Steel and Metal

Good quality, and straight! No wobbles, cut through ss nuts n bolts for lockwire, so im happy, highly recommended

Needed to drill holes into my window to fit some hooks but needed to get through the lintel. This made short work of it! Worked perfectly. Quality drill bits.

Work very well drilling in aluminium.Cannot fault.

I drilled through a rsj with this bit. It did the job okay

An excellent drill bit, good for drilling steel

Didnt drill into a cast iron road grate

I have a sheared off bolt to drill out, I've tried all my drills including sharpening bits after every try, and hardly touched it.So thought I would try these, but seeing how cheap they were and how many you got, I was not hopeful....HOW WRONG I WAS !! they are superb, I drilled into the end of a similar bolt and straight away it cut into the metal, with drilling and lubricating it drilled easily into the bolt. So I would easily recommend these drills, and at this price you cant go wrong.

Although we haven't used this drill bit others we've bought in this series have been absolutely perfect. Lasts well as good quality, drills without snapping and easy enough to change in the drill.
