## Questions & Answers

**Q: Would these be ok for a lintel above a window**
A: They will but you have to remember all lintels have reinforcing bars through then . If modern these bars will be 50mm from top and bottom so you need to drill to avoid them . Masonry drills  will not drill steel.

**Q: Are these suitable for drilling holes into ceramic plant pots?**
A: Yes without a doubt. 
I found these the most versatile bits I've ever owned. 
I used them to drill through ceramic wall tiles and then straight on through a concrete wall that is notorious for killing drill bits several holes later it still looks good. 
In my opinion you will not buy anything else after using these.

**Q: Are these definitely cobalt? Suitable for drilling stainless Steel as the back of blue packet they are packed in  says wood & plastic**
A: I have used the drills on stainless steel 1.5mm thick at a medium speed and plenty of coolant and found the result very good they seem to be very good quality for the price, i have used them most on plate steel up to 12mm thick with excellent results, as for them being cobalt i don't know !

**Q: Is it a makita dgd800z 18v li-ion lxt die grinder that is compatible**
A: Yes

A nice little set at a reasonable price. Just be warned some of these are tiny ... so tiny I can't see when you'd ever use them, so check what size you'd need first as I can only see me using maybe 1 or poss 2 sizes.
