Difference Between Drill Bits, Center Drill Bits, and Reamer

Let’s understand three different kinds of drill bits

Center drill bits

It consists of drill point, cutting edge and chip flute

It is mainly use to enlarge the hole with a pre-cast hole or bottom hole and improve the cylindricality and volume, but the hole is still not at this time

Use

1. It is generally use for semi-finishing or final machining of holes
2. For pre-processing of hinges or grinding
3. For expansion of rough holes
4. It can be used as a pinhole

Center drill bits have 3 to 4 edge bands, no cutting edges, and front and back corner-cutting

Advantage

1. The change of the blade is small
2. The guiding effect is good during machining
3. Resistance is small
4. Drilling conditions are subdivided into drilling holes

More about the Center Drill Bit

The drill bit

1. Compose of drill point, cutting edge and chip flute
2. It mainly processes work piece holes without pre-cast holes
3. The processed holes are generally of poor cylindricality and volume
4. It is use widely in the drilling of metal or other materials

More about the Twist Drill Bits

The drill bit and the center drill bit are the same things, but they have different roles

They both use the cutting edge to drill

The drill bit drilling in the bottom hole and the center drill enlarge the bottom hole of the drill bit

Reamer

Use

1. The reamer uses side blades for cutting
2. The reamer is used for reaming to achieve the accuracy and finish of the hole
3. A reamer is a type of rotary cutting tool used in metalworking

Composition

1. It consists of cutting edge and chip flute
2. It is mainly used to improve the circularity and displacement of the bottom hole
