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 improves adaptive scope, the change tooth bimetal 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 change tooth bimetal hole saw, comprise saw body, the left-hand end of described saw body is the stiff end fixing with saw body, the right-hand end of described saw body is and the integrated sawtooth of saw body, described sawtooth comprises full-height tooth section and becomes tooth section, in described full-height tooth section, be provided with and the integrated change tooth of full-height tooth section section, in described stiff end, be provided with fastener hole, the outside of described fastener hole is provided with locating hole, in the outer wall of described saw body, be provided with equally distributed chip-removal hole, the surface of the described external wall of saw is provided with graphite linings.
Graphite linings plays smooth effect, more laborsaving in use, reduces and the friction of sawing surface simultaneously, extends the service life of product.
As preferably, described change tooth section is by the first change tooth, second becomes tooth, the 3rd becomes tooth, the 4th becomes tooth, the 5th change tooth and the 6th change tooth successively continuous distributed form, the first described spacing becoming between the crown of tooth and the crown of the second change tooth is 4.9mm, the second described crown and the 3rd spacing that becomes the crown of tooth that becomes tooth is 4.65mm, the 3rd described crown and the 4th spacing that becomes the crown of tooth that becomes tooth is 5.2mm, the 4th described crown and the 5th spacing that becomes the crown of tooth that becomes tooth is 5.75mm, the 5th described crown and the 6th spacing that becomes the crown of tooth that becomes tooth is 5.45mm, the first described tooth depth that becomes tooth is 2.32mm, the second described tooth depth that becomes tooth is 2.22mm, the 3rd described tooth depth that becomes tooth is 2.45mm, the 4th described tooth depth that becomes tooth is 2.7mm, the 5th described tooth depth that becomes tooth is 2.55mm.
Become tooth section and full-height tooth section student's federation and close use, make result of use more outstanding.
As preferably, the wall thickness of described saw body is 1.27mm, and described locating hole is 4, and described fastener hole is screwed hole, and the inwall of described locating hole is provided with wearing layer.
Wearing layer effectively slows down the speed of wearing and tearing.
This structure can effectively improve the efficiency of use, and assembly performance is outstanding simultaneously, has preferably firm performance.
Therefore, the change tooth bimetal hole saw that the utility model provides, simple in structure, easy to operate, service efficiency is high.
