右ねじれのフルート溝２を有するツイストドリルに対して、該フルート溝２よりねじれ角の弱い副溝４を先端より延伸させ、その後端を前記フルート溝２に連通させる。 - 特許庁

When the outer peripheral cutting edge 38 is a helical flute inclined at a helix angle λ ranging from 3° to 17° in the opposite direction (counterclockwise helix direction) to the tool rotating direction, seen from the shank 32 side, the sharpness is improved to obtain a favorable machined surface (a finished surface), and a slant of a christmas tree formed groove is restrained.例文帳に追加

外周切れ刃３８をシャンク３２側から見た工具回転方向と反対方向（左ねじれ方向）へ３°〜１７°の範囲内のねじれ角λで傾斜したねじれ刃とすると、切れ味が向上して良好な加工面（仕上面）が得られるとともにツリー形溝のタオレが抑制される。 - 特許庁

The chip discharge flute 17 of the super-high pressure sintered drill 11 is formed so that the helix angle at the tip 21 that is a specific length away from the tip 23 becomes 0 degrees.例文帳に追加

超高圧焼結体ドリル１１の切り粉排出溝１７は、その先端２３から所定の長さの先端部２１においては、ねじれ角が０度になるように形成されている。 - 特許庁
