Abstract
The utility model relates to a hollow drilling bit for construction and decoration, which is composed of a drilling rod, a cutting head (or a grinding head) and a drilling handle, wherein, the drilling rod is a hollow cylinder body, a cylinder body wall is provided with more than one groove, the cutting head is fixed on one end of the drilling rod, and the other end of the drilling rod is connected with a connecting pin or a connecting screw to be connected with the drilling handle. The utility model uses an electric drill as rotating power, and hole drilling work is completed by rotating cut. Generated noises are lower than the noises generated by an impact drill or an electric hammer, no strong vibration is generated in work, the surrounding material of a drilled hole can not be damaged, and a drilled hole wall is smooth. The utility model is in a hollow annular shape. Compared with a solid drill bit, the utility model has the advantages that the cutting (or grinding) quantity is reduced, the hole drilling speed is rapid, the drill abrasion is little, the worker's labor strength is reduced and the hole drilling position is accurate.
Description
The utility model relates to the instrument of a kind of building and finishing usefulness, a kind of specifically building and finishing hollow drill bit.
Many local punching jewel holes that need are arranged in construction building and indoor and outdoor finishing, as: setscrew hole, pipe hole, air louver etc.All use at present the percussion drill or the electric hammer of dissimilar or model.Drill bit with this class instrument is solid, main dependence is back and forth impacted the material fragmentation of required punching is finished punching work, the noise that punching produces is big and hole that hit is of poor quality, and the material easy quilt in various degree around the hole shakes and splits, and has influenced the intensity of building and attractive in appearance to some extent; In addition, constructor's labour intensity is also very high.
The purpose of this utility model is to provide a kind of low noise, penetration rate fast, and the good and bore position of drilling quality is built accurately and fitted up and uses the hollow drill bit.
The purpose of this utility model is to realize in the following manner: a kind of building or finishing are used the hollow drill bit, are made up of drilling rod, cutting head (or grinding machine head) and drillstock, and drilling rod is the hollow cylindrical shell, and together above equally distributed groove is arranged on the barrel wall; Cutting head (or grinding machine head) is fixed on an end of drilling rod, and the other end of drilling rod is connected with drillstock by connecting pin or attachment screw.
Can adorn a locator in the hollow drilling rod of described hollow drill bit, this locator is made up of reference column and the carbide alloy center bit that is welded on the reference column, and the diameter of center bit is less than the diameter of reference column, and the external diameter of reference column is less than the hollow drill internal diameter; Have one on the reference column with its installation and be fixed in aperture in the hollow drilling rod; Center bit protrudes in cutting head or grinding machine head.As rotary power, rotary cutting is finished boring work to the utility model with electric drill, and the noise of generation is well below percussion drill or electric hammer; Also do not have judder during work, the material on every side of holing is damaged, institute's the wall of a borehole is smooth; And electric drill is cheap more than percussion drill and electric hammer, and the utility model is the hollow ring bit, significantly reduces than its cutting output with real core drill bit, and penetration rate is fast, bit wear is few, and constructor's labour intensity lowers.
Because the utility model is mainly used in the jewel hole (as: setscrew hole, pipe hole, air louver etc.) that punches on the concrete of building, because concrete is made up of cement, sandstone, the nonuniformity material, hardness is different everywhere, so drill bit is easy to displacement during boring, make the hole site that gets out often inaccurate, also can adorn a locator for addressing this problem in empty drilling rod, the center bit of locator at first contacts with concrete etc. during boring, and cutting head just began to cut an annular aperture after center bit pierced the concrete certain depth earlier.Cutting head to be cut (or during the grinding machine head incision 2-3mm degree of depth, stops boring, takes off locator, insert with this hollow drill bit and begin drilling deep hole in the ring-type locating hole of having accomplished fluently.This measure of employing can guarantee that the hole site that gets out is accurate.
The utility model content is described in detail in detail with reference to the accompanying drawings.
