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.

How do you soften steel for drilling?
Rebuild: The Skill That Helps You Drill Through Steel
Why can’t I drill through metal?
Drilling through metals create a lot of friction. This friction generates heat. The heat generated in the process not only damages your drill bits, but can also damage the metal you are drilling into.
Do you need special drill bits for metal?
Cobalt drill bits are used for drilling hard metal and steel. They dissipate heat quickly and are highly resistant to abrasions, making them better for drilling into hard metals than black oxide- or titanium-coated drill bits.
Why is my drill not making a hole?
The most common reason a drill won’t penetrate a wall at all is because the drill is spinning in the wrong direction. If the drill bit enters the wall and then hits resistance, the typical cause is a metal plate or masonry obstruction.
How can you tell if a drill bit is for steel?
Bits designed to drill metal have flutes that taper to a point at either a 118- or 135-degree angle. Bits with a 118-degree point are general-purpose bits, while those with a 135-degree point are self-cleaning, which means they shed shards of metal instead of allowing them to accumulate around the shank.
What is the hardest 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 can I use to drill through hardened steel?
Go to a hardware or home improvement store for a cobalt bit that is designed specifically for drilling through steel. You want a cobalt bit, as it’s a type of high-speed steel (HSS) that has more cobalt in it and is strong enough to cut through hardened steel.

What temp does steel soften?
Steel can be soft at 538°C (1,000°F) well below the burning temperature of jet fuel.
Can you soften hard steel?
Place the steel in a heat treat oven or forge and slowly raise the temperature of the steel to its particular austenite region. The austenite temperature region is different for each grade of steel and can usually be found from the foundry that produced the sample of steel.

Can you drill metal with a wood bit?
It does matter – wood drill bits won’t work on metal (destroying the bit in the process, unless used on thin and soft metals) and metal drill bits will increase splintering and tear-out when used on wood (but this depends also on the wood type and the diameter of the bit, and for smaller diameters there is little …

What are black drill bits used for?
Black Oxide Drill Bits – Basic and Inexpensive
This reduces friction between bit and workpiece, thereby speeding up the drilling process. Bits made with a black oxide coating are suitable for work on steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon, and composite materials.
Which is better cobalt or titanium drill bits?
Cobalt drill bits are more expensive, but offer longer life, and are more resistant to heat than titanium drill bits. Cobalt drill bits are also tougher and can drill holes in the hardest metals.
Are titanium drill bits good for metal?
Choosing the right one is essential for doing any project correctly and efficiently. For most more challenging projects, you’re going to be choosing between cobalt and titanium drill bits. Both of these bits are designed to drill through metal, making them durable and tougher than most drill bits.
How do you stop a drill bit from slipping on metal?
To keep a drill bit from wandering when drilling in metal, put the point of a center punch or nail set on the spot you want the hole, then tap it with a hammer to make a small dent in the metal. Chuck the drill bit in the drill, place the bit on the dent, and drill the hole.
How do you drill for the first time?
To use a drill for inserting a screw into a pilot hole, follow these steps:
- Power up the drill.
- Adjust the torque so it’s low.
- Fit the screw into the slot on the drill bit.
- Line up the screw with the hole.
- Make sure the drill is vertical.
- Pull the trigger on the drill and press gently into the screw.
How do you stop a drill bit from falling off?
Insert the drill bit into the drill chuck. Tighten the drill chuck only by hand until it clicks several times. Rotate the chuck back the opposite way, until you hear and feel one, single click. Once you hear and feel the last click, the drill bit is locked securely into place.
What are the gold drill bits for?
Bosch Gold Oxide Drill Bits offer added speed and durability for general-purpose drilling applications in wood, metal and plastic. The gold oxide coating helps to provide longer life than ordinary high-speed steel drill bits by resisting heat buildup.
What is cobalt drill bit?
What are cobalt drill bits? Cobalt bits are a combination of steel (or another alloy) mixed with a small percentage of cobalt, typically between 5 – 7%. Cobalt has a melting point of 1495°C and a boiling point of 2927°C, which makes it perfect for use at high temperatures.
