Hardened steel is resistant to wear and high-impact pressure, making it a choice material for applications that require hard-wearing materials. These characteristics can also make it challenging to machine hardened steel. Read on to discover the best drill bits for drilling into hardened steel.

If you’re looking for a tool to cut through hardened steel, check out the cobalt drill bit sets at Drill Bit Warehouse. Our premium M42 drill bits come in various lengths to suit your project needs. Shop with us today for high-performance drill bits.

Carbide is a compound composed of carbon and a metal. Carbide drill bits are tungsten carbide and can contain cobalt for enhanced durability. Carbide drill bits can handle higher temperatures than cobalt drill bits.

A balance between cutting speed and feed rate is necessary to achieve optimal chip evacuation and prevent chip recutting. The feed rate for aluminum milling is ...

Cobalt drill bits contain an alloy of five to eight percent cobalt. M35 bits contain approximately five percent cobalt, and M42 bits contain about eight percent cobalt.

Cobalt drill bits are often the best for drilling into hardened steel. Whereas titanium drill bits only have titanium in the coating, cobalt bits have cobalt throughout. After cobalt drill bits get worn out over time, you can resharpen them.

Hardened steel is medium- or high-carbon steel that has been given heat treatment, rapidly cooled and tempered. The high amount of carbon in the steel makes it possible to harden the metal.

To reduce the risk of injury, read the instruction manual and follow the safety regulations of the power tool you will be using with your Spyder accessory. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, protective apparel and hearing protection should be used in appropriate conditions to reduce the risk of personal injury. WARNING: Operating the tool without wearing proper protection may result in serious injury. To reduce the risk of explosion, electric shock, and property damage, always check the work area for hidden gas pipes, electrical wires, and water pipes when making blind and/or plunge cuts. Before each use, check that the hole saw is free from damage and excessive wear. Discard hole saw if damage is noticed or suspected as this can cause excessive friction, saw binding, kickback, create dangerous flying debris and/or create other unsafe situations that may cause injury. Hex-based pilot bits are intended to be used with hex-based arbor adapters and hole saws. Use a pilot bit which is correctly sized for the hole saw being used. Always be sure that the pilot bit extends beyond the cutting edge of the saw by at least ¼”; for deep cut hole saws, the pilot bit should extend at least 1” beyond the cutting edge of the saw. Follow the recommended operating speed for the saw size and the material being cut. Use the proper pilot bit and hole saw for your material. Only drill materials that are listed on the product label. Use a drill motor that is equipped with a support handle. Start cutting with a light forward pressure. For cuts that are square to the surface, start the cutting process with the saw square to the material being cut so all teeth begin to cut at the same time. This will help prevent premature wear and damage to the saw. Feeding the saw in and out or using a slight circular rocking motion may assist in clearing material shavings from the hole being cut. When sawing in wood, finish the hole from the opposite side to prevent splintering. Once the pilot bit has broken through the other side, you can use this hole to guarantee you are in line with where you have already started cutting.

The more cobalt the bit contains, the harder the metal it can drill through. But the tradeoff is that increasing the cobalt increases the drill bit’s brittleness. Be sure to use the appropriate drilling techniques to preserve your cutting tools.

For TCT saws recommended for use on concrete products, brick, or tile materials – make sure to check the Mohs hardness of the material being drilled. Materials like poured concrete, some brick/block, floor tile, ceramic tile, porcelain, etc. may have a Mohs hardness of higher than 6, and the TCT hole saw is not recommend for use in these drilling applications.

Titanium drill bits are one option for drilling hardened steel. These drill bits are high-speed steel bits coated with titanium nitride. High-speed steel bits that consist of vanadium and tungsten can drill through soft steel, but they won’t cut through hardened steel.

These drill bits can be tungsten carbide tipped or full body. Carbide-tipped bits can drill through hard, non-metallic materials like masonry. If you want to drill hardened steel with tungsten carbide, use a full-body bit.

A UNF thread size chart will offer a perfect guide to choose the most suitable thread needed for your specific requirements.

The titanium nitride coating has a dark gold appearance, improves wear resistance, and reduces friction. Since the titanium nitride is just a coating, once your drill bit wears down, you cannot resharpen it and maintain its performance level. The titanium layer will no longer be on the drill bit except in the fluting and perhaps on the sides.
