Metal Drill Bits

Whether you're a professional contractor or a home DIY enthusiast, using the proper tools can make a world of difference. This is especially true when working with metal materials. Using proper drill bits for metal will prevent unnecessary damage to both your equipment and the metal itself and will reduce the possibility of injury. Bosch Professional offers a wide range of metal cutting drill bits that are designed to provide superior performance.

Drill bits come in various shapes and sizes, each designed for a specific purpose. When it comes to a drill bit that goes through metal, it should be high-speed steel (HSS) and feature a coating that helps reduce heat and friction when drilling. You can usually tell which bits have a coating by the colour of the metal drill bit.

The Bosch range of HSS drill bits for metal includes twist bit, step bit, slanting hole, countersink, stub, and double-ended drill bits that are available in different types of shank interfaces: 3-flats, cylindrical, double-ended, and hex shank drill bits. These are all compatible for rotary drills and drivers as well as impact drills and drivers.

The type of the accessory you need will depend on the type of metal you're drilling and the size of the hole you need to drill. Bosch metal drill bits are capable to drilling through different types of metal. Our range of metal drilling accessories contains steel drill bits, as well as drill bits for stainless steel, aluminium, cast iron, metal pipes and metal sandwich.

It's important to consider the size of the drill bit needed to drill through the metal in relation to the thickness of the metal you’re working with. Bosch Impact Control HSS twist drill bits are ideal for drilling holes in thick steel or cast iron, while a step drill bit that goes through sheet metal easily will eliminate the need for pre-punching thin sheets of the material.

Make sure to keep the following in mind before using a metal bit for grinding and drilling:

• Use a lower speed setting. Metal is a lot harder than other materials like wood or plastic, so you'll need to use a slower speed to avoid damaging the bit.
• Apply pressure evenly as you drill. This will help prevent the bit from slipping and potentially breaking.
• Start with a smaller drill bit and work your way up to the size you need. This will make it easier to get through tougher metals without damaging the material or the bit.
