Tungsten Carbide Flat Bottom Drills 180° Countersunk Head CNC Machining

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.
