[Q] What is the difference between a twist drill, an end mill, and a slot milling cutter?

[A] A twist drill is a tool that drills a circular hole in a workpiece by rotating it relative to a fixed axis. It is named because its chip groove is spiral and resembles a twist. The main cutting edge 

of the end mill is on the cylindrical surface, and the cutting edge on the end face is the secondary cutting edge. An end mill without a center edge cannot feed along the axial direction of the 

milling cutter when working. According to national standards: the diameter of the end mill is 2-50 mm, and it can be divided into coarse teeth and fine teeth. The diameter of 2-20 is the 

straight shank range, and the diameter of 14-50 is the taper shank range. The slot milling cutter has a shorter cutting edge than the drill bit and has sufficient rigidity. In the case of a blind 

hole, it can be cut downward or moved horizontally. It usually has two teeth, and the slot milled out under normal circumstances is reduced.

[Q] How to process dovetail slot milling cutter

[A] 1. Make a dovetail template 2. Mark the workpiece and punch the sample 3. Use a planer to plan, or use a tower milling cutter on a vertical milling machine 4. Use a template to test the 

accuracy of the finished product

[Q] Does the 65-degree dovetail slot milling cutter belong to the national standard milling cutter?

[A] Does the 65-degree dovetail slot milling cutter belong to the national standard milling cutter? I searched for a long time, but there were only 45 to 60 degrees. But the master in our 

factory said that 65 degrees and 70 degrees are both national standards. Is that right?

[Q] What is a screw slot milling cutter and what is it used for? What is the difference between it and a saw blade milling cutter?

[A] If the tungsten steel milling cutter is worn, it can be sharpened with a tungsten steel milling cutter grinder. Our company uses the milling cutter grinder of Tuoer Machinery, and the effect 

of grinding the milling cutter is very good.

[Q] Is there a 2 cm high 45 degree dovetail milling cutter?

[A] Tungsten steel cutters are made up of many tungsten carbide particles. The larger the particles, the lower the hardness; the smaller the particles, the higher the hardness; the most essential 

difference between 45 degree and 55 degree cutters lies in the size of the material particles. The 45 degree cutter has a large particle size and low hardness; the 55 degree cutter has a small 

particle size and high hardness. A milling cutter is a rotating cutter with one or more teeth used for milling. When working.
