Abstract

　加工穴径（Ｄ）に対する加工穴深さ（Ｌ）が１５倍以上の加工において、切屑の噛み込みを抑制し、加工穴の真直度が得られるドリル径が１ｍｍ以下の深穴加工用小径ドリルを提供する。 　小径ドリル１は、ドリル径２が１ｍｍ以下でドリル部５に切刃３と溝４を有している。溝４の溝長１１はドリル径２の５倍以上１０倍以下となっている。ドリル部５は、切刃３からドリル部５の後方に向かって縮径した後、溝４の終端での外径がドリル径２の０．９倍以上０．９８倍以下となるように拡径し、シャンク７につながる首部６との間に、溝４の終端９での外径よりドリル径２の１倍以下まで拡径した拡径部１０を備えている。首部６の直径はドリル径２より小さく、かつ、首部６の長さ１２はドリル径２の１０倍以上となっている。
