Abstract

本实用新型公开了一种木工钻,包括依次连接为一体的钻体和钻柄,在钻体前端设有锥形钻尖、主切削刃和副切削刃,在锥形螺尖上设有螺旋凸起,所述的钻柄为三角形柄,在钻柄上还设有定位沟槽。本实用新型具有钻孔方便且能加工高精度孔的优点。

Description

一种木工钻
技术领域
本实用新型属于木工领域,更具体地说,是涉及一种木工钻。 
背景技术
    现有的木工钻,钻孔速度慢,钻孔产生的木屑不能及时排出,容易阻塞钻孔路径,只能用于加工精度不高的孔。 
实用新型内容
本实用新型的目的是提供一种钻孔方便且加工精度高的木工钻。 
本实用新型采用的技术方案为:一种木工钻,包括依次连接为一体的钻体、和钻柄,其中,在钻体前端设有锥形钻尖、主切削刃和副切削刃,在锥形螺上设有螺旋凸起,所述的钻柄为三角形柄,在钻柄上还设有定位沟槽。 
本实用新型采用上述的结构,通过在钻体前端设有锥形钻尖、主切削刃和副切削刃,在锥形螺尖的周边均布设有螺旋凸起,钻柄为三角形柄,在钻柄上还设有定位沟槽,便于装夹,结构简单,容易操作,省时省力,可以用来加工精度要求较高的孔。 
附图说明
图1是本实用新型的主视图。 
图中:1为钻体 ,2为钻柄 ,21为定位沟槽 ,3为锥形钻尖 ,31为螺旋凸起 ,4为主切削刃 ,5为副切削刃 。 
具体实施方式
如图1所示,一种木工钻,包括依次连接为一体的钻体1和钻柄2,在钻体1前端设有锥形钻尖3、主切削刃4和副切削刃5,在锥形螺尖3上设有螺旋凸起31,钻柄2为三角形柄,在钻柄2上还设有定位沟槽21。 
本实用新型在具体钻孔时,设置在锥形螺尖3上的螺旋凸起31能使钻孔能不需要其它的推进力就能靠自身旋转力自动进退,钻孔速度快,增加了工作效率。 

Claims (1)
