Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、穴あけ用ドリル刃の構造に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to the structure of a drill bit for drilling holes.
従来、穴あけ用ドリル刃としては、任意の一定の径の刃
のみを有する構造となっていた。Conventionally, drill blades for drilling holes have been constructed to have only a blade having an arbitrary fixed diameter.
上述した従来のドリル刃は、径が一定であるので、例え
ば第2図(a)、 (b)のように従来のドリル刃6に
よりプリント板4に穴あける時、バリ5が発生する。バ
リ5は通常、別に何らかの方法で除去する必要がある。Since the conventional drill blade described above has a constant diameter, burrs 5 are generated when drilling a hole in the printed board 4 with the conventional drill blade 6, as shown in FIGS. 2(a) and 2(b), for example. The burr 5 usually needs to be removed by some other method.
このように従来のドリル刃は、穴をあける時、穴あけ作
業とバリの除去作業の2作業が必要であるという欠点が
ある。As described above, the conventional drill blade has the drawback that when drilling a hole, two operations are required: drilling and removing burrs.
本発明の面取り刃付ドリル刃は、穴あけ用ドリル刃部分
とそれにつづいて同一軸上に穴あけ用ドリル刃により径
の太い面取り用ドリル刃部分を有している。The drill blade with a chamfering edge according to the present invention has a drill bit part for drilling and a drill bit part for chamfering having a larger diameter on the same axis.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

よび面取りは完了している。FIG. 1(a) is a front view of an embodiment of the present invention. The drill blade 1 is a drill blade with the diameter of the hole to be drilled, the connection part 2 is a connection part that does not have a blade smaller in diameter than the drill blade 1, and the drill blade 3 is a drill blade with a larger diameter than the drill blade 1. be. 1st
Figures (b) to (e) are schematic diagrams showing the state in which the drill blade shown in Figure 1 (a) is drilling a hole in the printed circuit board 4. Figure 1(b) is a diagram showing the state before drilling,
Figure (c) is a diagram showing a state in which a hole is drilled with the drill blade 1, and burrs 5 are generated. Figure 1(d) shows the drill blade 3.
Fig. 1(e) is a diagram showing a state where chamfering is performed at
This is a diagram showing a state in which the drill is pulled up, and drilling and chamfering have been completed.

果がある。As explained above, the present invention has the effect that drilling and chamfering can be performed in one operation by equipping the same drill with a drill bit for drilling and a drill bit for chamfering.
