What type of drill bit should I use for drilling into metal?

For drilling into metal, high-speed steel (HSS) drill bits are generally recommended. Cobalt drill bits, offered by brands like Milwaukee Electric Tools, are even better for harder metals like stainless steel due to their increased heat resistance. Look for bits with a split point tip for easier starting and reduced walking.

How do I choose the right size drill bit for my project?

The correct drill bit size depends on the size of the hole you need to create. If you're drilling a pilot hole for a screw, match the drill bit size to the screw's shank diameter. For other applications, carefully measure the desired hole size and select a drill bit accordingly; it's always a good idea to test on scrap material first.

What's the difference between a jobber length and a screw machine length drill bit?

Jobber length drill bits are the most common type, offering a good balance of length and rigidity for general-purpose drilling. Screw machine length drill bits are shorter and more rigid, making them suitable for use in screw machines and other applications where space is limited and accuracy is crucial. Brands like Century Drill & Tool offer both types.

What materials are drill bits made of, and how does that affect their performance?

Drill bits are commonly made from high-speed steel (HSS), cobalt, or carbide. HSS bits are suitable for general-purpose drilling, while cobalt bits are more heat-resistant and ideal for harder metals. Carbide bits are the hardest and most durable, best for abrasive materials like concrete or tile. Consider the material you'll be drilling when selecting your drill bit.

What is a split point drill bit, and when should I use one?

A split point drill bit has a specially designed tip that helps prevent walking and allows for easier starting, especially on curved or smooth surfaces. This design is particularly useful when drilling into metal or other hard materials where a standard drill bit might tend to wander. Many brands, including Irwin, offer split point drill bits for improved accuracy and efficiency.

How do I properly care for and maintain my drill bits to extend their lifespan?

Proper care is essential for extending the life of your drill bits. Avoid overheating by using appropriate drilling speeds and applying cutting fluid when drilling metal. Regularly inspect your bits for damage and sharpen them as needed. Store your drill bits in a protective case or organizer to prevent damage and keep them organized.

What are some common applications for different types of drill bits?

Different drill bits are designed for specific applications. Twist drill bits are general-purpose, while spade bits are used for drilling large holes in wood. Masonry bits are designed for drilling into concrete or brick, and tile bits are specifically for drilling through ceramic or porcelain tile. Consider the material and the size of the hole you need to drill when choosing the right bit.
