Description

Tungsten steel drill bit for tapping

Technical Field

The utility model relates to a cutting tool field especially relates to a tungsten steel drill bit for trompil.

Background

Tungsten steel, also known as cemented carbide, refers to a sintered composite material comprising at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide and tantalum carbide are common components of tungsten steel. The main application of tungsten resources is also cemented carbide, i.e. tungsten steel. Cemented carbide, known as modern industrial teeth, tungsten steel products are used to a very wide extent. The tungsten steel drill bit that is used for the trompil at present is functional than more single, all is used for drilling usefulness, and has neglected to combine the function of drilling and trompil together, brings bigger usefulness for the tungsten steel drill bit, and prior art does not have dustproof function moreover, and dust splashes in the drilling, increases later stage cleaning work.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a tungsten steel drill bit for trompil, includes drill stem end, drill bit end and drill point, drill stem end links to each other with drill bit end together, the drill bit is served and is equipped with a plurality of helicla flutes, forms the chip groove of falling between helicla flute and the helicla flute, the drill point is inlayed at the end of drill bit, the anterior segment of drill stem end is close to helicla flute department cover and is equipped with the trompil head, the one end of trompil head is equipped with the installation hole site, the trompil head other end is the cutting edge, encircles and is equipped with the brill tooth that is used for opening the round hole on the cutting edge, and this trompil head is fixed at the drill stem.

It is worth explaining, the utility model discloses a tungsten steel drill bit and trompil head can be dismantled separately exclusive use separately, and the installation hole site of trompil head can adapt to the installation of emery wheel polisher, has realized the multi-purpose function of a thing.

Furthermore, an inner threaded hole A is formed in the drill handle end, an inner threaded hole B which is installed in a matched mode with the inner threaded hole A is formed in the side wall of the installation hole of the tapping head, and the tapping head is sleeved on the drill handle end through the installation hole and is locked and fixed through an inner hexagonal screw.

Furthermore, the dust blocking plate is fixed at the end of the drill handle through an inner hexagon screw, and detachable dust absorption cotton is arranged in the dust blocking plate.

Further, the dust blocking plate is made of transparent materials.

The utility model discloses following beneficial effect has: compared with the prior art, the utility model discloses a practicality is strong, except having the basic function of drilling, still has the function of trompil, and its drill bit can be dismantled separately exclusive use separately with the trompil head, has realized the multi-purpose function of a thing, has dustproof function simultaneously, and the in-process dust-retaining disc of trompil or drilling can block the dust, avoids splashing and brings more cleaning work for the user.

Drawings

Fig. 1 is a schematic view of the overall structure of the tungsten steel drill for drilling according to the present invention.

In the figure: 1. a drill shank end; 2. drilling a head end; 3. drilling a tip; 4. chip grooves are chamfered; 5. opening a hole head; 6. mounting hole sites; 7. drilling teeth; 8. a dust-blocking disc; 9. a hexagon socket head cap screw; 10. a socket head cap screw; 11. dust-absorbing cotton.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1, in the embodiment of the tungsten steel drill bit for drilling, the tungsten steel drill bit for drilling includes a drill handle end 1, a drill bit end 2 and a drill tip 3, the drill handle end 1 is connected with the drill bit end 2, a plurality of spiral grooves are arranged on the drill bit end 2, chip-falling grooves 4 are formed between the spiral grooves, the drill tip 3 is embedded at the tail end of the drill bit, a drilling head 5 is sleeved at a position, close to the spiral grooves, of the front section of the drill handle end 1, a mounting hole site 6 is arranged at one end of the drilling head 5, the other end of the drilling head 5 is a cutting edge, drill teeth 7 for drilling round holes are arranged on the surrounding cutting edge, the drilling head 5 is fixed at the drill handle end 1 through the mounting hole site 6, and a dust-blocking disc 8 is arranged at the rear.

In order to facilitate the respective disassembly and use, an inner threaded hole A is formed in the drill handle end 1, an inner threaded hole B which is installed in a matched mode with the inner threaded hole A is formed in the side wall of an installation hole position 6 of the tapping head 5, and the tapping head 5 is sleeved on the drill handle end 1 through the installation hole position 6 and is locked and fixed through an inner hexagonal screw 9.
