Flat-bottom drills are nifty tools. Those that have true 180-degree flat cutting edges can create holes on inclined or curved surfaces without a preliminary center drilling operation to create a start hole. And unlike conventional drills, flat-bottom drills tend to shear material as it exists the back side of a workpiece instead of pushing through, leaving behind a minimal burr.
The video above demonstrates this. Produced by , it shows a slow-motion comparison of a conventional drill and the company’s Aqua Drill Ex Flat completing a through-hole. You can see the tip of the conventional drill pushing through the material, whereas the flat-bottom drill performs more of a shearing operation. The video also shows the flat-bottom drill creating holes in inclined and contoured surfaces without requiring a starter hole.
