Abstract
The utility model provides a hole saw, and particularly relates to a sand-grain hole saw. The sand-grain hole saw comprises a saw body, wherein the left side end of the saw body is provided with bosses distributed uniformly; hard sand grains are arranged on each of the bosses; the right side end of the saw body is a fixed end; a center fixing hole is formed in the fixed end; the outer side of the center fixing hole is provided with positioning holes; the outer wall of the saw body is provided with scrap discharge holes distributed uniformly; the height of the hard sand grains is 2.7mm; the thickness of the hard sand grains is 2.5mm; the wall thickness of the saw body is 1.27mm; the wall thickness of the saw body is smaller than that of the fixed end; a wearing layer is arranged in a connection part between every two adjacent bosses. The sand-grain hole saw is simple in structure, convenient to operate and high in use efficiency.
Description
Technical field
The utility model is a kind of hole saw, particularly a kind of sand grains hole saw.
Background technology
The result of use relative deficiency of hole saw of the prior art is required great effort while operating simultaneously relatively, cannot meet the demand of present stage.
Summary of the invention
Utility model is mainly to solve the deficiencies in the prior art, and a kind of structure relative compact is provided, and has stable result of use, improves adaptive scope, the sand grains hole saw of effectively enhancing productivity simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of sand grains hole saw, comprise saw body, the left-hand end of described saw body is provided with equally distributed boss, described boss is provided with hard sand grains, the right-hand end of described saw body is stiff end, in described stiff end, be provided with center fixing hole, the outside of described center fixing hole is provided with locating hole, the outer wall of described saw body is provided with equally distributed chip-removal hole, the height of described hard sand grains is 2.7mm, the thickness of described hard sand grains is 2.5mm, the wall thickness of described saw body is 1.27mm, the wall thickness of described saw body is less than the wall thickness of stiff end, between described boss, junction is provided with wearing layer.
Wearing layer is the speed that effectively slows down wearing and tearing, for conventional position, adds wearing layer, can effectively extend the service life of whole equipment.
As preferably, the aperture of described center fixing hole is greater than the aperture of locating hole, and described center fixing hole is screwed hole, and the pitch-row between phase next but two locating hole is 25.4mm, described chip-removal hole is strip hole, and described saw body and the total height of hard sand grains are 45 ~ 46mm.
As preferably, the outer wall of described saw body is provided with graphite linings.
The effect of graphite linings is in use, and more smooth outer wall can be provided, and reduces resistance, reaches better operating effect.
This structure can effectively improve the efficiency of use, and assembly performance is outstanding simultaneously, has preferably firm performance.
Therefore, the sand grains hole saw that the utility model provides, simple in structure, easy to operate, service efficiency is high.
