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

Here you may wonder what’s the difference between endmill and drill bit? Can an endmill can be used as drill bits? What’s the difference between reamers and end mills?

Secondly, it has 1 cutting edge, 2 cutting edges, 3 cutting edges and 4 cutting edges. Some finishing requires 6 flutes.

Besides, the common milling cutter diameter is 1~25mm, if less than 1mm, it is often called the micro-end mill cutter. Most of them will use the “arbor + cutter blade”, disk milling and other methods to mill.

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.

In addition, according to the shape, 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.

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.

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.

For tungsten carbide end mill bits, it is a kind of equipment used in drilling engineering. And its main function is drilling, which are 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.

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 drilling, but it is not the mainstream.

In a word, above are the main points for their difference. Hope this file can give you a better understanding of these two products.

On the contrary, for cemented carbide drills, it 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.
