Abstract

本实用新型公开了一种双刃双翼三尖钻。旨在提供一种结构简单、钻孔阻力小的双刃双翼三尖钻。它包括由刀体和刀柄,在刀体前端的中心制有钻尖、刀体上制有两条主切削刃、副切削刃、螺旋沟槽,在每条副切削刃的前端制有高出主切削刃的圆周切削刃,其特征是在副切削刃的表面制有顺副切削刃旋转的排屑槽。该实用新型的优点是:由于副切削刃的表面制有排屑槽,在钻孔时,附着在副切削刃表面的木屑经排屑槽排出,排屑通畅,钻出的孔壁光滑。

Description

双刃双翼三尖钻
技术领域
本实用新型属于木材加工工具,特别涉及木工钻孔用的双刃双翼三尖钻。
背景技术
目前所用的木工钻,大多是由螺尖、两条主、副切削刃、刀体及双头螺旋沟槽组成。但由于木工钻切削量大、进给速度快,排屑量大,在副切削刃的表面会存在许多木屑,造成钻削阻力大、钻体发热,工作效率低的现象。
实用新型内容
本实用新型的目的是提供一种结构简单、钻孔阻力小的双刃双翼三尖钻。
为了达到上述要求,本实用新型是通过以下技术方案实现的:它包括由刀体和刀柄,在刀体前端的中心制有钻尖、刀体上制有两条主切削刃、副切削刃、螺旋沟槽,在每条副切削刃的前端制有高出主切削刃的圆周切削刃,其特征是在副切削刃的表面制有顺副切削刃旋转的排屑槽。
该双刃双翼三尖钻的优点是:由于副切削刃的表面制有排屑槽,在钻孔时,附着在副切削刃表面的木屑经排屑槽排出,排屑通畅,钻出的孔壁光滑。
附图说明
图1是双刃双翼三尖钻的主视图;图2是图1的放大左视图。
图中:1、刀体;2、刀柄;3、钻尖;4、主切削刃;5、副切削刃;6、螺旋沟槽;7、圆周切削刃;8、排屑槽;9、圆弧定位沟槽。
具体实施方式
下面结合附图和具体实施例对本实用新型作进一步的描述。
它包括由刀体1和刀柄2,在刀体1前端的中心制有为四棱锥的钻尖3、刀体1上制有两条主切削刃4、副切削刃5、螺旋沟槽6,在每条副切削刃5的前端制有高出主切削刃4的圆周切削刃7,在副切削刃5的表面制有顺副切削刃5旋转的排屑槽8。刀柄2正六棱柱,在刀柄2上制有周向的圆弧定位沟槽9。
