Flat Bottom Drills - stock available, customs to order

We offer a proprietary design flat bottom drill with and without coolant through capability.   Solid carbide with and without coating. The bits are custom made from solid carbide and excellent chip evacuation as they drill, minimizing burring and leaving a smooth finish. This eliminates the need for a finishing pass after drilling.

These tools are great for spot facing, and drilling inclined, curved, and interrupted surfaces.

We will soon list stock drills in our webstore at www.ekstromcarlson.shop, but contact us for your needs as required.

Flat Bottom Drill Applications:

Flat bottom drills are the perfect solution when conventional drills or end mills cannot achieve the required accuracy. These tools excel in:

  • Drilling holes with flat bottoms for counterbores and spot facing

  • Working on curved or inclined surfaces where standard drills would walk or chatter

  • Creating shallow holes with minimal burr formation

  • High-precision work in aerospace, automotive, and mold & die industries

For detailed reference on drilling standards and machining practices, see the Machinery’s Handbook, a trusted resource for engineers worldwide.
