6. The most intuitive difference is whether there is an apex angle at the tip. The drill bit is to make holes, so there must be an apex angle to help orientate, while the milling cutter is to mill the plane, mainly relying on the edge, with no apex angle.

For tungsten carbide end mill bits, it is a kind of equipment used in drilling engineering. And its main function is drilling, which is through holes and blind holes, respectively referring to the original holes for reprocessing, and the original holes without holes to drill. The general processing size is 2~40mm. Most are twist drill, flat drill, center drill, deep hole drill, and sleeve drill. Although reamers and countersinks cannot drill holes in solid materials, they are traditionally classified as drill bits.

8. The cutter is a rotary cutter with one or more teeth for milling. When working, each cutter tooth intermittently cuts the residual of the workpiece.

As you know, the carbide end mill is the most general use milling cutter tool on CNC machines. They can be cut simultaneously or separately, which is mainly used for plane milling, groove milling, step face milling, and profiling milling. There is a flat-bottomed end mill, ball nose end mill, corner radius end mill, forming cutters, chamfering cutters, T-shaped cutters, and roughing end mills for your choice.

1. First, different processing requirements: end mills are for milling, while drill bits are for drilling and reaming. Although in some cases, the milling cutter can also drill, it is not mainstream.

Have you ever noticed that the shape of end mill bits is similar to the drill bits? And do you know their difference? Both end mill and drill bit are CNC cutting tools, while they differ greatly in structure, usage, and price. Here is an article about their details for your reference.

7. The side edge of the milling cutter has a relief angle, so it can be cut sideways. The side edge of the drill has no relief angle, so it cannot be cut laterally.

3. Third, various categories, the former is sharp and shovel tooth milling, and the later is a diamond drill bit, roller cone bit, and scraper drill bit.

The drill bit has four basic types: solid carbide drills, cemented carbide indexable insert drills, welded cemented carbide drills, and replaceable cemented carbide crown drills. And each drill bit has its benefits and specific processing conditions.

5. The drill bit is relatively long, and the two blades of the outer circle have no clearance angle, which only reduces friction. The two blades do not intersect at one point, and there is a chisel edge, which has many dimensions every 0.1 mm.

4. The milling cutter is very short. The two cutting edges of the outer circle have clearance angles, which can play a cutting role. They intersect at a point and there is almost no chisel edge. It has only integer dimensions.
