Tapered tools, 11° taper

A taper 11 degree tool refers to a tool with a taper of 11 degrees at the front end of the tool. This type of drill rod is mainly used in equipment such as rock drills and coal mining machines to feed and extract brazing material. Due to its large taper at the front end, it is easier to feed the brazing material into the hole, and at the same time, it is also easier to remove the brazing material during rock drilling or coal mining processes.

taper

Taper refers to the distance from the vertex of one geometric shape to the vertex of another geometric shape, which can be expressed by the formula d=k/l. Among them, d represents taper, k represents taper coefficient, and l represents the length of the straight line segment.

The degree of taper can be adjusted as needed, commonly including 1 degree, 2 degree, 3 degree, and 5 degree. The larger the taper, the smaller the axial distance, and the greater the radial distance. The front end taper of this type of drill rod is 11 degrees, which is larger than ordinary drill rods, making it easier to feed the solder into the hole.

Drill rod material

Drill rods are usually made of materials such as high-speed steel or hard alloy. High speed steel is a high-performance cutting tool material with good wear resistance and toughness, suitable for manufacturing cutting tools such as drill rods. Hard alloy has high hardness and wear resistance, and is also one of the commonly used drill rod materials.

Usage occasion

Drill rods are mainly used in equipment such as rock drills and coal mining machines to feed and extract brazing material. During rock drilling or coal mining, the drill rod will come into contact with the hole wall, so it needs to have high wear resistance and corrosion resistance. When feeding and extracting brazing material, it is necessary to have good feeding and extracting performance.

In summary, the taper 11 degree drill rod is a commonly used drill rod in equipment such as rock drills and coal mining machines. Its front end taper is 11 degrees, which has good wear resistance and corrosion resistance, and is suitable for use in harsh environments.
