Abstract

PURPOSE:To conduct hole making and planing off the corners at one time work, by providing at a drill a hole making drill edge portion, and in succession to this and on the same axis, a planing off corners drill edge portion whose diameter is larger than that of the hole making drill edge. CONSTITUTION:The diameter of a drill edge 1 is made to be the same with that of a hole to be opened, and a connection portion 2 is made to be the portion which is smaller in diameter than the drill edge 1 and has no edge, and a drill edge 3 is made to be larger in diameter than the drill edge 1. In the case of hole making being done at a print base plate, burs are generated as the drill edge 1 is used, but planing off the corners is conducted by means of the drill edge 3 and hole making and planing off the corners are completed at a time.

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.

〔従来の技術〕[Conventional technology]

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.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

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.
