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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very pleased *by L***B on 17 August 2026* Very pleased did the job required ### ⭐⭐⭐⭐ It's for DIY Not for regular professionals use *by T***I on 17 June 2026* For this price I can't complain it can do 2 to 3 jobs perfect but after that you and yor luck. ### ⭐⭐⭐⭐⭐ Small bit *by M***N on 1 September 2026* Good ## Frequently Bought Together - HPMAISON True 5% Cobalt Drill Bit Set, 13Pcs M35 High Speed Steel Twist Drill Bits 1.5mm-6.5mm, 135° Split Point Extremely Heat Resistant for Stainless Steel, Cast Iron, Hard Metal, Plastic, Wood - Rennie Tools - Box of 10 x 1mm HSS Gold Cobalt Jobber Drill Bit Set For Stainless Steel, Hard Metals, Aluminium, Cast Iron, Copper.
