The Ultimate Buying Guide for Drill Bits for Wood
Picking the right drill bit makes woodworking easier and safer. This guide helps you choose the perfect bit for your next project. We cover what to look for and how to use them well.
Key Features to Look For
Good drill bits have specific designs that help them cut wood cleanly. Pay attention to these parts when you shop:
1. Tip Type
The tip does the hard work. Different tips suit different jobs:
- Spur or Brad-Point Tips: These are the best for general woodworking. They have a sharp center point that stops the bit from wandering. They create clean entry and exit holes.
- Auger Bits: These have deep, screw-like threads. They pull the bit through the wood quickly. They are great for drilling deep, wide holes.
- Forstner Bits: These bits make very flat-bottomed holes, perfect for cabinet hinges or plug cutting. They cut a clean outer rim first.
2. Flute Design
Flutes are the spiral grooves along the bit’s body. They clear wood chips (swarf) out of the hole. Longer, deeper flutes remove more material faster. Shorter flutes work better in harder woods where you drill slower.
3. Shank Type
The shank is the smooth part that goes into the drill chuck. Most wood bits use a standard round shank. Ensure the shank fits your drill tightly to prevent slipping.
Important Materials for Durability
The metal the bit is made from affects how long it lasts and how fast it cuts.
- High-Speed Steel (HSS): This is common and affordable. HSS bits work well for softwoods like pine. They can dull faster than harder materials.
- Cobalt or Carbide-Tipped: These bits are much harder. They handle tough, knotty woods or abrasive materials better. They cost more but last much longer.
- Black Oxide Coating: This coating reduces friction. It keeps the bit cooler during drilling, which helps the bit stay sharp longer.
Factors That Improve or Reduce Quality
Quality matters for a smooth finish. Several factors influence a bit’s performance:
Factors Improving Quality:
- Sharpness: Very sharp cutting edges reduce the force needed to drill. This prevents tear-out (splintering) on the wood surface.
- Precision Grinding: Bits ground precisely run true (don’t wobble). Wobbling creates oversized or uneven holes.
- Heat Treatment: Proper heat treatment hardens the steel correctly. This keeps the tip sharp after many uses.
Factors Reducing Quality:
- Soft Steel: Bits made from very soft steel dull quickly. You must stop often to sharpen them.
- Burrs on Edges: Rough spots or burrs left from manufacturing cause the bit to tear the wood instead of cutting it cleanly.
- Incorrect Sharpening: If a bit is resharpened poorly, the geometry changes. The bit will then cut poorly or drill crooked holes.
User Experience and Use Cases
Different jobs require different bits. Using the right bit improves your experience greatly.
Softwoods vs. Hardwoods:
When drilling softwoods (like pine or cedar), almost any sharp bit works well. For hardwoods (like oak or maple), you need a tougher bit, like one tipped with carbide. Hardwoods require slower speeds to prevent overheating the bit.
Pilot Holes:
Always drill a small pilot hole before using large screws or large bits. Pilot holes guide the main bit and prevent the wood from splitting. Spur-point bits are excellent for starting these small guide holes.
Depth Control:
If you need a hole of an exact depth, look for bits with depth stops. These collars slide onto the bit. They stop the bit from drilling deeper than you set. This is crucial for consistent furniture making.
10 Frequently Asked Questions (FAQ) About Wood Drill Bits
Q: What is the best type of bit for general-purpose drilling in wood?
A: The brad-point or spur-tip bit is usually the best choice. It keeps the hole straight and clean.
Q: Should I use high speed or low speed when drilling wood?
A: Generally, use lower speeds for harder woods and larger bits. Higher speeds are okay for softwoods with small bits, but too much speed creates heat and burns the wood.
Q: How do I prevent the wood from splitting when the bit comes out the back?
A: Drill slowly as you near the exit point, or clamp a piece of scrap wood underneath (a backing board). The scrap wood supports the fibers as the bit breaks through.
Q: What does “flutes” mean on a drill bit?
A: Flutes are the spiral channels on the bit. They act like scoops to carry wood shavings out of the hole as you drill.
Q: Are expensive drill bits worth the extra money?
A: Yes, often they are. Higher-quality bits use better steel and are ground more precisely. This means they stay sharp longer and cut cleaner holes.
Q: Can I use metal drill bits on wood?
A: You can, but they won’t work as well as wood bits. Metal bits tend to wander and leave rougher exit holes because they lack the center spur of a wood bit.
Q: How deep should I lubricate a drill bit when drilling wood?
A: You usually do not need lubrication (like oil) for standard wood drilling. Lubrication is mostly for drilling metal to reduce heat.
Q: What is a Forstner bit used for?
A: Forstner bits create flat-bottomed holes. They are perfect when you need a clean seat for a hinge or a hidden screw head.
Q: How often should I clean my wood drill bits?
A: You should clean off wood chips after every few holes. Inspect the cutting edges regularly for dullness or damage.
Q: What is the shank size, and why does it matter?
A: The shank is the part that grips the drill. You must make sure the shank size matches what your drill chuck can hold securely. A loose fit causes slipping and damages the bit.
