Choosing the Best Drill Bits: Your Ultimate Buying Guide
Drilling holes is a common task for many projects, from hanging shelves to building furniture. But to get clean, accurate holes, you need the right drill bits. This guide will help you understand what makes a drill bit “rated” and how to pick the best ones for your needs.
What Makes a Drill Bit “Rated”?
When we talk about “rated” drill bits, it usually means they are made from good materials and are designed for specific tasks. They perform well and last a long time.
Key Features to Look For
When you’re shopping for drill bits, keep these important features in mind:
1. Shank Type
The shank is the part of the drill bit that goes into your drill.
- Round Shank: This is the most common type. It fits in most drill chucks.
- Hex Shank: This has a hexagonal shape. It grips the chuck better and stops the bit from slipping. It’s great for powerful drills.
2. Flute Design
Flutes are the spiral grooves on the drill bit.
- Straight Flutes: Good for softer materials like wood and plastic.
- Spiral Flutes: These help clear away debris as you drill. They are better for harder materials and deeper holes.
- Deep Flutes: These are extra long and help remove a lot of material quickly.
3. Point Type
The tip of the drill bit is important for starting the hole.
- Center Point: This sharp point helps you start drilling exactly where you want. It prevents the bit from “walking” or slipping.
- Spur Point: This type has small spurs that score the wood before the main cutting edges enter. It makes for very clean holes in wood.
- Self-Drilling Point: Some bits have a tip that acts like a screw. They can create their own pilot hole and even thread the hole in one step.
4. Coatings
Coatings can make drill bits stronger and last longer.
- Black Oxide: This common coating adds some rust resistance and helps bits run cooler.
- Titanium Nitride (TiN): This yellow coating is very hard. It makes bits last much longer and cut through tough materials faster.
- Cobalt: This is an alloy that is mixed with steel. It makes the bit very strong and heat-resistant, perfect for drilling metal.
Important Materials
The material a drill bit is made from greatly affects its performance.
- High-Speed Steel (HSS): This is a very common and affordable material. HSS bits are good for general-purpose drilling in wood, plastic, and some metals.
- Cobalt Steel: As mentioned, cobalt is added to HSS to make it much harder and more heat-resistant. Cobalt bits are excellent for drilling hard metals like stainless steel.
- Carbide: This is an extremely hard material. Carbide-tipped bits are used for drilling very hard materials like concrete, masonry, and tile.
Factors That Improve or Reduce Quality
- Good Quality: Bits made from high-quality steel, with precise manufacturing, and helpful coatings (like titanium or cobalt) are generally better. Sharp cutting edges and well-made flutes also improve quality.
- Poor Quality: Bits made from cheap metal can dull quickly. Poorly ground cutting edges make drilling difficult and messy. Bits that aren’t heat-treated properly can bend or break easily.
User Experience and Use Cases
The best drill bit for you depends on what you need to drill.
- Woodworking: For general wood drilling, HSS bits with a center point or spur point work well. For very clean holes in fine woodworking, brad-point bits are excellent.
- Metalworking: For softer metals like aluminum or mild steel, HSS bits are usually fine. For harder metals like stainless steel, you’ll need cobalt or titanium-coated bits.
- Masonry and Concrete: You need special masonry bits, often with carbide tips, for drilling into brick, concrete, and stone. These bits work with hammer drills for the best results.
- DIY Home Projects: For tasks like hanging pictures or assembling furniture, a good set of general-purpose HSS bits will serve you well. If you’re doing more involved projects, consider investing in specialized bits.
Frequently Asked Questions about Drill Bits
Q: What is the most common type of drill bit?
A: The most common type of drill bit is a general-purpose bit made from High-Speed Steel (HSS) with a round shank and spiral flutes.
Q: When should I use a titanium-coated drill bit?
A: You should use a titanium-coated drill bit when you need to drill faster and the bit needs to last longer, especially in harder materials like metal.
Q: How do I know if a drill bit is good for metal?
A: Drill bits made from cobalt steel or coated with titanium nitride are good for drilling metal, especially harder types of metal.
Q: What is a spur point drill bit used for?
A: A spur point drill bit is used for drilling clean holes in wood. The spurs score the wood before cutting.
Q: Can I use wood drill bits on metal?
A: You can sometimes use regular wood drill bits on very soft metals, but it’s not ideal. They will dull quickly and won’t make clean holes. Special metal drill bits are much better.
Q: How can I make my drill bits last longer?
A: You can make your drill bits last longer by not forcing them, using the correct speed for the material, and keeping them sharp. For metal, using a lubricant can also help.
Q: What is the difference between a round shank and a hex shank?
A: A round shank fits in most drill chucks. A hex shank has six sides and grips the chuck more securely, preventing slipping, especially in powerful drills.
Q: Are carbide drill bits only for concrete?
A: Carbide drill bits are most commonly used for very hard materials like concrete, masonry, and tile. They are much harder than steel bits.
Q: What does “self-drilling” mean for a drill bit?
A: A self-drilling bit has a tip that can create its own pilot hole and even thread the hole in one go, saving you a step.
Q: How do I choose the right size drill bit?
A: The size of the drill bit you need depends on the size of the hole you want to make. You can often find the desired size marked on screws or bolts, or measure the area where the hole needs to be.
