A) How to drill through metal – step by step guide
1 Identify the metal you want to drill through.
Before you can decide the best drill bit for steel you must first of all know what steel you intend to drill.
2 Decide what type of drill bit to use.
Because there are many drill bits that drill through metal it is important to choose the best one for the item you are drilling. Metal drill bits vary in cost, durability and ability to drill different metals. The ultimate guide to drill bits will certainly help you decide what drill bit to use.
3 Choose a suitable drill.
If you are using a hand drill it is best to use one with variable speed control. This is because different metals drill best at different drilling speeds. You can refer to one of our our metal drilling speed chart. Imperial drill bit speed and feed chart.
4 You should use a suitable metal lubricant.
A drilling paste or lubricant oil will reduce friction whilst drilling which will help reduce heat build up.
5 Use appropriate pressure.
Avoid using too much pressure as this will cause excessive heat build up.
6 Wear suitable protection.
Finally you should always wear eye protection when drilling. Also depending on how long you will be working for you may want to wear ear protectors also.

B) Customer reviews
If you are drilling through steel you want the the best metal drill bit chances are you will buy a cobalt drill bit.
Cobalt drill bits are the best drill bits for hard metals including stainless steel. If you are using a hand drill then a 5% (M35) drill bit will be most suitable and it will be less brittle than other drill bits. TTP HARD drill bits are 5% cobalt and are a high quality drill bit.
Below are just some of the reviews from customers who have used TTP HARD cobalt drill bits for drilling through metal.
“HAPPY TO RECOMMEND”
“Great buy. Have used drills from well known manufacturers, but these are better. Would recommend them and will be using again”
“1/2” PLATE STEEL”
“The drill has drilled several holes through 0.25 inch plate steel and is still going strong!”
Steven Eugene Raiguel
“RUSTED SCREW HEADS”
“Good for drilling out rusted screw heads for lifting hardwood decking – very effective indeed”
“LIKE A HOT KNIFE THROUGH BUTTER”
“Just to let eveyone know these drill bits are BRILLIANT, it is the first time I have ever worked with metal and was using titanium bits, managed 3 holes with 3 drill bits. Then I ordered TTP bits and they were like a hot knife through butter. I was drilling 1cm hard steel and the job was so easy. Highly recommended. Don’t buy expensive immitations”
“BEST HAVE EVER USED”
“These are by far the best metal drill bits I have ever used hands down. I hesitated to purchase these bits for a while because of the price but finally pulled the trigger and I can say I was stupid for not buying them right away. If you are thinking of buying these but are hesitant because of the price do yourself a favour and get them, you will save time and money in the long run.”
“CUTTING PASTE HELPS DRILLING”
“Upon testing this products with various drill sizes into hardened angle iron steel. It worked GREAT – keep in mind when drilling metal – DRILL SPEED can be your enemy. Fast will burn the bit out even with cutting lubricant. Slow and Constant will get a clean and nice hole each and every time without blowing a bit for no reason. This is a nice find and addition to my tool bench.”
We have included a few videos of TTP HARD drill bits in action. The important tips which can be seen in all videos are:-
You will notice that the speed is always low or moderate so the drill bit can do the work
You should always use lubricant when drilling because it will aid drilling and prevent overheating
When you take a break you allow the drill bit to cool down
