Flat Bottom Drill Bit

A flat bottom drill bit is a tool used for drilling holes, characterized by a flat bottom, which provides better positioning and stability during drilling. Flat bottom drill bits are commonly used in metalworking, woodworking, and plastic processing industries, and are suitable for applications that require high-precision hole locations.

Material

Flat bottom drill bits are typically made from carbide materials , to ensure the hardness and wear resistance of the drill bit.

Shape

The cutting edge of the flat bottom drill bit is designed with sharp cutting edges, with a sharp point at the center for centering.

Use

Flat bottom drill bits are suitable for drilling various materials, especially in metalworking where precise hole locations are required. They are often used for creating hinge holes, screw holes, etc.

Usage Method

When using a flat bottom drill bit, it is usually necessary to pre-drill a pilot hole with a center drill to ensure the drill bit can be accurately positioned when starting to drill. The rotational speed and feed rate of the drill bit need to be adjusted according to the material type and drill bit size.

Flat bottom drill bits are commonly used tools in manufacturing and handicraft industries. Correct selection and use of flat bottom drill bits can improve work efficiency and processing precision.
