Carry out the most people to like wearing beads, when worried, noisy, especially not adorn, to be free from arrogance and rashness,
And earnestly hope safety, long protect happiness happy, and beads outside religion implied meaning, more become the symbol of fashion culture.People
Often need beads to be through on rope to form string by the hole of bead, thus use as bangle or extension pearl.
Existing beads hole is relatively big with the friction of rope, can aggravate the abrasion of rope, and rope is easily broken off, thus
Cause the loss of beads, therefore need the two ends reconditioning chamfering in beads hole, to reduce beads hole to rope
Friction, slows down the abrasion of rope.
At present, during being processed beads, the chamfering for two ends, beads hole is the most artificial
Manual reconditioning is main, after being drilled beads hole by drill bit, then by artificial by frustrating the instrument reconditionings two such as cutter
The chamfering of end, it can increase the workload of workman, and the efficiency of chamfering reconditioning is low, of poor quality.
The information being disclosed in this background section is merely intended to increase general background of the present utility model
Understand, and be not construed as recognizing or imply in any form that this information structure is for the general skill in this area
Prior art well known to art personnel.
Utility model content
The purpose of this utility model is to provide a kind of beads hole machined subland drill, thus overcomes existing
Carry out by manually chamfering to two ends, beads hole that the efficiency of manual reconditioning is low and ropy shortcoming.
For achieving the above object, this utility model provides a kind of beads hole machined subland drill, wherein,
Including: drillstock；Drilling rod, it is arranged at the front end of described drillstock, the hole in the diameter of this drilling rod and beads hole
Footpath is identical；The front end of this drilling rod is provided with apex point, and described apex point is made up of two symmetrical cutting edges；
First chip area, on described drilling rod, helical ring is provided with two respectively these corresponding with described cutting edge first
Chip area；Second chip area, the front end helical ring of described drillstock is provided with two each and described first rows
This second chip area that bits groove is connected；And before chamfering blades, the rear end of described drilling rod and described drillstock
The junction of end is symmetrically provided with two these chamfering blades, and this chamfering blades tilts backwards from the inside to the outside.
Preferably, in technique scheme, a length of the 30 of described drillstock～50mm, and described drillstock
A diameter of 8～15mm.
Preferably, in technique scheme, a length of the 18 of described drilling rod～30mm, and described drilling rod
A diameter of 2～4mm.
Preferably, in technique scheme, described chamfering blades is arc-shaped.
Preferably, in technique scheme, the radius of described chamfering blades is 3～7mm.
Compared with prior art, this utility model has the advantages that
Drilling rod of the present utility model can process beads hole by apex point on beads, and can lead to simultaneously
Crossing chamfering blades and beads hole is carried out chamfer machining, its simple in construction, working (machining) efficiency is high, and process falls
Cutin amount is good, and it can be substantially reduced the labor intensity of the beads course of processing.

Fig. 1 shows a kind of beads hole machined subland drill according to this utility model preferred implementation
Structural representation, this beads hole machined subland drill includes drillstock 1, drilling rod 2, apex point the 3, first chip removal
Groove the 4, second chip area 5 and chamfering blades 6, with reference to Fig. 1, drillstock 1 is cylindrical, and it is for dynamic
Power head connects.Drilling rod 2 is arranged at the front end of drillstock 1, and drilling rod 2 is the most cylindrical, the diameter of drilling rod 2
Less than the diameter of drillstock 1, drill bit entirety is stepped.The diameter of drilling rod 2 is identical with the aperture in beads hole,
Beads can carried out the beads hole size that Drilling operation just obtains needing.The front end of drilling rod 2
Being provided with apex point 3, apex point 3 is made up of two symmetrical cutting edges 31, before two cutting edges 31
