Continuing our exploration on Drill Bits—because at Garrison Dales, we stock one of the most extensive ranges of drill bits around.
We’ve covered Step Drills and Cone Drills, now let’s head into the world of wood drilling. Visit all our wood drills here: Wood Drill Bits Collection ›.
Here’s how the three main types compare:
♠️ Flat Wood Drill Bits (Spade Bits)
- Ideal for: Fast through-holes in softwood, such as for cable routing or rough carpentry.
- Design: A paddle-shaped flat blade with a centre point and cutting spurs.
- Finish: Quick drilling—though not razor-sharp clean.
🪵 Wood Auger Drill Bits
- Ideal for: Deep, clean holes in thicker timber—great for carpentry, structural work, or utility holes.
- Design: Spiral fluted shape improves chip removal and reduces clogging.
- Finish: Smooth, accurate holes with minimal splintering.
🇯🇵 Japanese Wood Auger Drill Bits
- Ideal for: Precision drilling in finish carpentry or joinery.
- Design: Tapered point and razor-edge cutting—minimal effort, maximum accuracy.
- Finish: Extremely clean and refined—perfect for fine woodworking.
🧰 Which One Should You Use?
👉 Flat Wood Bits when you need speed and ease in softer materials.
👉 Wood Auger Bits for deeper drilling and better chip evacuation.
👉 Japanese Auger Bits when precision and surface finish matter.
