To provide a twist drill perforating a material with hardness of a degree of structural steel or a pre-hardened material by a drill with superior chip discharge ability enhancing cutting speed, feed rate, and efficiency, reducing burrs generated in the perforating, and eliminating deburring after the perforating.例文帳に追加

構造用鋼、プレハードン材程度の硬さの被削材を、より切り屑排出性に優れたドリルで、切削速度、送り速度も高く、能率を高め、更に、穴あけ加工におけるバリの発生を減少させ、穴あけ後のバリ取り等を行わずにするツイストドリルを提供する。 - 特許庁

To provide steel by which the formation of burrs, occurring in the case where a deep hole with a depth of ≥10 D is bored using a small-diameter drill of ≤10 mm drill diameter D made of cemented carbide or coated with cemented carbide, can be suppressed and which can be suitably used as a material for machine structural parts requiring high dimensional accuracy.例文帳に追加

ドリル径Ｄが１０ｍｍ以下の超硬合金製あるいは超硬合金をコーティングした細径ドリルを用いて、深さ１０Ｄ以上の深穴を加工する際のバリ形成を抑制することができ、高い寸法精度が要求される機械構造部品の素材として好適な鋼材の提供。 - 特許庁

To provide a tubular joint in which a plurality of structural parts are jointly integrated with each other by friction welding while weld beads are not regulated, or protruded inside, and to reliably feed cutting solution in a drill tool having the tubular joint.例文帳に追加

溶接ビードが規制されずに内部に突出することなく複数の構造部分が摩擦溶接により一体的に結合された管状継手を実現すると共に、そのような管状継手を具えるドリル工具において切削液の確実な供給を保証することにある。 - 特許庁
