Abstract
The invention relates to a drilling reamer. The drilling reamer comprises a working part and a handle part which is integrally connected with the working part, wherein the working part comprises a twist drill part arranged on the front end of the working part, and a reamer part connected behind the twist drill bit; the twist drill and the reamer part are connected by a shoulder part. Rough machining and fine machining for bores can be carried out in sequence by only one drilling reamer provided in the invention; during the period, a cutter is not exchanged, thereby greatly shortening machining time, improving production efficiency and saving production cost.
Description
Technical field
The present invention relates to a kind of cutter that is used to hole with hole processing, particularly a kind of fluted drill and reamer are set to the drilling reamer of one.
Background technology
Usually, when carrying out the hole operations, general roughing operation such as use that fluted drill is holed earlier; Re-use reamer fine finishining is carried out in the hole, so, need use two cutters at least; And need the calibration of tool setting again when changing cutter; Operating efficiency is lower, is unfavorable for saving production cost, and wastes time and energy.
Summary of the invention
To the problems referred to above, the purpose of this invention is to provide a kind of roughing and accurately machined cutter that can carry out the hole simultaneously, to increase work efficiency.
Technical scheme of the present invention is:
. a kind of drilling reamer, comprise working portion and the shank that connects as one with working portion, said working portion comprises the fluted drill portion that places the working portion front end, be connected in the reamer portion behind the spiral bit, is connected by shoulder between said fluted drill and the reamer portion;
Said fluted drill drift angle be set to 140
;
Tool cutting edge angle
scope of said reamer portion be 3
--- 4
The number of teeth of reamer is 4.
Beneficial effect of the present invention is:
Only use this drilling reamer of the present invention, successively carry out the roughing and the fine finishining in hole, during need not change cutter, shortened the time of hole processing greatly, improved production efficiency, practiced thrift production cost.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is an A-A cutaway view of the present invention.
The specific embodiment
Like Fig. 1, shown in Figure 2,
Drilling reamer of the present invention comprises working portion and shank 4, and said working portion and shank are connected as a single entity, and working portion is by the fluted drill portion 1 that places front end, and reamer portion 3 is connected in shoulder 2 compositions between fluted drill portion 1 and the reamer portion 3.The drift angle angle of fluted drill be 140
; The tool cutting edge angle of reamer portion
scope be 3
-4
, the number of teeth of reamer is 4.
