What drill bit is best for metal?
What drill bit is best for metal?
Regular drill bits can’t cut through steel, so you need a heavy-duty, hard drill bit to do the job. There are two types of drill bits that you can count on for metalworking projects: titanium and cobalt. Titanium drill bits are high-speed steel drill bits (HSS) that have a titanium oxide coating.
Are there drill bits for metal?
In fact, most drill bits for metal are manufactured to drill through a variety of materials, including wood and plastic. The least expensive twist bits are made of high-speed steel (HSS), and these basic bits are just fine for most metal-drilling tasks.
What is the toughest drill bit for metal?
Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades. Carbide (Carb) is the hardest and most brittle of the drill bit materials.
What are the 5 types of drill bits?
The 20 Types of Drill Bits
- Twist Drill Bits. Also known as high-speed bits, they resemble corkscrews and are some of the most popular bits.
- Brad Point Drill Bits.
- Masonry Drill Bits.
- Rivet Drill Bits.
- Spade Drill Bits.
- Installer Bits.
- Step Bits.
- Auger Bits.
Can a cordless drill go through metal?
Using a cordless drill, the right type of drill bits, and following the protocol, you can easily drill a clean hole through any metal.
Can I use wd40 for drilling metal?
Multi-Purpose Cutting Oil is designed to improve the performance and extend the life of your cutting and drilling equipment. You can use it on either stainless steel or titanium components. It prevents pitting and metal seizures, eases mechanical processing of metals, and reduces heat and damage caused by friction.
Why can’t I drill through metal?
Drilling into a hard surface requires the use of specialized drill bits. Regular drill bits are not designed to cut through metals. Therefore, they can easily wear away. So you need hard bits which can drill through metals without being damaged.

What are the Gold drill bits for?
For drilling into metal Metal bits are also known as high-speed steel (HSS) or twist bits. They are usually black but sometimes gold in colour (gold ones are usually specially coated for extra durability). Metal-drilling bits can be used for drilling plastic and wood, but you should never use wood bits to drill metal.
What are small drill bits called?
Screw Machine Length: Also called “stubby length”, these are the shortest common drill bits. Originally designed for screw machines, many people prefer these due to their high strength and added working clearance.
Which is better titanium or carbide drill bits?
Titanium-coated HSS drill bits produce less friction. They’re tougher than basic HSS bits and stay sharp longer. They work for drilling wood, metal, fiberglass and PVC. Carbide-tipped drill bits stay sharp much longer than steel, HSS or titanium bits.
Should you use cutting oil when drilling metal?
We recommend you always use a metal cutting fluid or lubricant when you are drilling. There are 3 main reasons you should use a cutting paste: Reduce friction. Assist cooling.
What is the best drill bit for cutting metal?
Titanium drill bits are high-speed steel drill bits (HSS) that have a titanium oxide coating. They are very hard, and corrosion-resistant. They last much longer than regular HSS drill bits, and they are good for cutting through any metal, including metal sheeting.
What is the strongest drill bit for metal?
The basis for many of the hardest drill bits is tungsten carbide. A metal that is five times stronger than steel, tungsten carbide by itself makes for a very hard drill that’s quite resistant to heat. However, it can be brittle, so only the tips of many bits are made of this metal, though it isn’t uncommon for entire drill bits to be made of it.
What are the best HSS drill bits for metal?
M1 HSS. It’s softer compared to the others and more resistant to shock.
What are the best drill bits for very hard steel?
Cobalt drill bits are made of cobalt steel, and they can be sharpened. They are also highly resistant to heat and are very hard and abrasive. They are especially good for drilling through stainless steel, cast iron and titanium .
