Abstract
【解決手段】ホールソーの下部外周には、刃先1aを除いて周溝となる凹溝2が円周方向に形成され、刃先1aと凹溝底下部にはポリエチレンワックス3がコートされ、ポリエチレン管穿孔時には刃先のみがポリエチレン管と接触して接触面積を少なくし、かつポリエチレンワックスのコートにより摩擦係数を小さくして摩擦抵抗を軽減する。
【選択図】図1
Description
この種ホールソーの一例が下記特許文献1に開示されている。
1a・・刃先
1b・・嵌合部
1e・・ネジ
2、8、10・・凹溝
3・・ポリエチレンワックス
Claims (1)
- サドル部と該サドル部より突設される主幹部を備えた継手をサドル部でプラスチック管に熱融着又は電気融着後、前記主幹部を通してプラスチック管に穿孔する際に用いるホールソーであって、プラスチック管への穿孔時にプラスチック管との接触面積を少なくするため刃先を除く外周面に凹溝を1ないし複数箇所設けたことを特徴とするホールソー。
