Best Drill Bits for Wood

Wood drilling has evolved with all the bit types, material options, and sizing considerations flying around. As someone who has drilled through every wood species, I taught myself the working side of choosing the right bits. Today, I will share it all with you.

Bit Types

Probably should have led in this case, candidly—different bits serve different purposes:

• Twist Bits: General purpose, available everywhere
• Brad Point: Clean entry, reduced wandering
• Spade Bits: Fast, larger holes, rougher finish
• Forstner Bits: Flat-bottomed, clean holes
• Auger Bits: Deep holes, excellent chip clearance

Selection Factors

• Hole size required
• Finish quality needed
• Drilling depth
• Wood hardness

Tips for Better Results

• Use backing board to prevent blowout
• Keep bits sharp
• Match speed to bit size
• Clear chips frequently in deep holes
