Abstract
The utility model relates to a chamfering twist drill, and belongs to a machining tool. The chamfering twist drill comprises a drill handle and a drill body. The chamfering twist drill is characterized in that a tapered chamfering platform is fixed on the drill handle, and a chamfering blade is fixed on the chamfering platform. The chamfering twist drill is reasonable in structural design, chamfering operation can be carried out without the need of replacing a drill bit, and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of chamfering fluted drill, belongs to a kind of machine tools.
Background technology
Fluted drill be rotary cutting by its relative fixed axis with the instrument of the circular hole of drilling workpiece, gain the name because its chip area curl is similar to fried dough twist.Because the machining requirement needs to do chamfering to the hole of having bored, existing operation is after getting out a hole with fluted drill first, bit change or target moved on on another bench drill machine more again, the drill bit larger with diameter carries out the chamfering operation, wastes time and energy inefficiency.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and a kind of fluted drill is provided, and reasonable in design can be increased work efficiency.
The technical scheme in the invention for solving the above technical problem is: a kind of chamfering fluted drill, comprise drillstock and drill body, and be characterised in that: be fixed with the chamfering platform of taper at described drillstock, be fixed with chamfering blades at the chamfering platform.
Chamfering blades described in the utility model is obliquely installed.
The utility model compared with prior art has following advantage and effect: reasonable in design, need not more that bit change just can carry out the chamfering operation, and can increase work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Referring to Fig. 1, the utility model embodiment comprises drillstock 1 and drill body 2, and drillstock 1 and drill body 2 are as a whole, are made by carbide alloy.
The 1 chamfering platform 3 that is fixed with taper is fixed with chamfering blades 4 at chamfering platform 3 on drillstock, and chamfering blades 4 is obliquely installed.Chamfering platform 3, chamfering blades 4 and drillstock 1 are as a whole, are made by carbide alloy.
During work, get out a hole with drill body 2 first after, again toward moving down drill body 2, until chamfering blades 4 is run into the edge in hole, just can carry out the chamfering operation to the hole.Chamfering blades 4 is obliquely installed, so that chamfering efficiency is higher.
Claims (2)
1. a chamfering fluted drill comprises drillstock and drill body, is characterised in that: be fixed with the chamfering platform of taper at described drillstock, be fixed with chamfering blades at the chamfering platform.
2. chamfering fluted drill according to claim 1, it is characterized in that: described chamfering blades is obliquely installed.
