Carbide Flat Bottom Drills  for Flat-bottom Hole

Flat bottom drill for metalworking is a type of drill bit that has a flat bottom instead of a pointed or rounded one. 

This design allows for more accurate and precise drilling, especially in applications where a flat bottom hole is required, such as for countersinking or creating a flat surface for a bolt head or washer. 

Flat bottom drills are commonly used in metalworking, particularly for drilling holes in steel, aluminum, and other metals. 

They are available in a range of sizes and materials, including high-speed steel (HSS) and carbide, and can be used with both hand-held and machine drills.
