Best analysis： How many types of drills are there
Everyone knows that drill bits are the most consumed consumable among all tools, but how many people know how many types of drill bits are there??
A high-speed steel drill bit is a tool that rotates and has the cutting ability at the tip. It is generally made of carbon steel SK or high-speed steel SKH2, SKH3, etc., which is milled or rolled and then quenched and heat treated. Drilling on other materials.It has a very wide range of applications, and can be used on drilling machines, lathes, milling machines, hand drills and other machine tools..According to different types, drill bits can be divided into the following types:
A. Classified by structure
1. Integral drill bit: drill top, drill body and drill shank are integrally manufactured from the same material.
2. End-welded drill: the top of the drill is welded by carbide.
B. Classification by drill
1. Straight shank drill: the drill diameter is less than 13.Straight shank is used below 0mm.
2. Taper shank drill bit: the bit shank is tapered, and the taper is generally Morse taper.
C. Classification by purpose
1. Center bit: generally used for centering before drilling, the front end cone has 60, 75, 90, etc..
2. Twist drill: the most widely used high-speed steel drill in industrial manufacturing.
3. Super hard drill bit: the front end of the drill body or all of it is made of super hard alloy tool material, which is used for drilling of processing materials.
4. Oil hole drill: The drill body has two small holes, through which the cutting agent reaches the cutting edge part to take away heat and chips. Use this drill to rotate the work while the drill is stationary.
5. Deep hole drill: It was first used for the drilling of barrels and stone-clad tubes, also known as barrel drills..The deep-hole high-speed steel drill bit is a straight groove type, which cuts a quarter of the strong part in the round pipe to produce cutting edge chip removal .
6. Drill bit reamer: the front end is a drill bit, the back end is a reamer.The diameter of the drill bit and the diameter of the reamer only differ from the allowance for reaming. There are also drill bits that are used in combination with screw tapping, so they are also called hybrid drill.
7. Taper drill bits: Taper drill bits can be used when processing the mold inlet.
8. Cylindrical hole drill: We call it a countersunk milling cutter. The part with a smaller diameter at the front end of this high-speed steel drill is called a ball.
9. Tapered hole drill: for drilling tapered holes, the front end angles are 90, 60, etc..The chamfering knife we use is one of the tapered high-speed steel drills.
10. Triangular drill: A drill used for electric drills. The shank of the drill is made into a triangular face so that the chuck can secure the drill..
