Abstract

The utility model relates to a drill reamer, which comprises an operating portion and a handle. The handle is integrally connected with the operating portion, the operating portion consists of a twist drill and a reamer, the twist drill is arranged at the front end of the operating portion, the reamer is connected to the rear of a drill bit of the twist drill, the twist drill is connected with the reamer by a shoulder. Rough machining and fine machining of a hole can be successively carried out only by the drill reamer, the drill reamer does not need to be replaced during operation, hole machining time is greatly shortened, production efficiency is improved, and production cost is saved.

Description

A kind of drilling reamer
Technical field
The utility model relates to a kind of cutter that is used to hole with hole processing, and 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.
The utility model content
To the problems referred to above, the purpose of the utility model provides a kind of roughing and accurately machined cutter that can carry out the hole simultaneously, to increase work efficiency.
The technical scheme of the utility model is:
. a kind of drilling reamer; Comprise working portion and the shank that connects as one with working portion; It is characterized in that 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, be connected by shoulder between said fluted drill and the reamer portion;
Said fluted drill drift angle be set to 140 ;
The tool cutting edge angle k scope of said reamer portion be 3 - 4
The number of teeth of reamer is 4.
The beneficial effect of the utility model is:
Only use this drilling reamer of the utility model, 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.
