Abstract

本实用新型公开了一种螺旋刀具,包括刀杆和刀头,刀头为螺旋状,刀头上设置有排屑槽,所述排屑槽的槽底设有条形突起,该条形突起从排屑槽前端顺着排屑槽走向一直延伸至该排屑槽的后端,所述刀杆上还设有容屑槽,所述容屑槽与排屑槽相连通。本实用新型结构简单,成本低,利用断屑口与容屑槽的设置防止切屑在刀具上缠绕以及在开孔进口处累积。

Description

一种螺旋刀具
技术领域
本实用新型涉及一种刀具,特别是一种螺旋刀具。
背景技术
钻头是一种钻孔的工具,它可与多种机械配合使用,十分方便。但现有技术钻头的不足是:在钻孔的过程中其钻头的排屑槽容易被屑末挤堵,使其排屑缓慢而降低了钻孔的速度,增大了钻头的扭力,使钻头容易被折断。
实用新型内容
本实用新型的目的在于针对背景技术中所述的现有的螺旋刀具存在的切屑不易排出的问题,提供一种螺旋刀具。 
能够实现本实用新型的发明目的的技术方案如下: 
一种螺旋刀具,包括刀杆和刀头,刀头为螺旋状,刀头上设置有排屑槽,所述排屑槽的槽底设有条形突起,该条形突起从排屑槽前端顺着排屑槽走向一直延伸至该排屑槽的后端,所述刀杆上还设有容屑槽,所述容屑槽与排屑槽相连通。
本实用新型的有益效果为:由于在排屑槽的槽底设有从该排屑槽的前端延伸至排屑槽后端的条形突起,当钻头在钻孔排屑时,其条形突起可起到疏通屑末的作用,使钻头的排屑槽不易被屑末挤堵,提高了钻孔的速度,钻头也不会因扭力过大而容易被折断;同时在刀杆上设置容屑槽,允许让排屑槽内的小段刀屑进入容屑槽中,避免小段刀屑无法排出从而积在开孔进口处,卡死刀具。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
 如图1所示,本实用新型螺旋刀具,包括刀杆1和刀头2,刀头2为螺旋状,刀头2上设置有排屑槽3,所述排屑槽3的槽底设有条形突起4,该条形突起4从排屑槽3前端顺着排屑槽3走向一直延伸至该排屑槽3的后端,所述刀杆1上还设有容屑槽5,所述容屑槽5与排屑槽3相连通。
以上所述的仅是本实用新型的优选实施方式,应当指出,对于本领域的技术人员来说,在不脱离本实用新型结构的前提下,还可以作出若干变形和改进,这些也应该视为本实用新型的保护范围,这些都不会影响本实用新型实施的效果和专利的实用性。
