AI Technical Summary
Technical Problem
Existing cutting tools generate a lot of heat during machining, leading to premature damage, and the existing coolant channels are complex and costly to manufacture.
Method used
Design a cutting tool with multiple spaced-apart helical grooves and helical coolant channels extending from the shank to the tip. The coolant orifice outlet is adjacent to the chip groove path and spaced from the tip. The coolant channels rotate in the same or opposite directions, and the coolant orifice outlet directionally guides the coolant to the high-wear area.
Benefits of technology
It effectively reduces heat and stress in cutting tools, extends tool life, simplifies manufacturing processes, and reduces costs.

Abstract
切削刀具的主体可包括柄部和具有间隔开的螺旋沟槽的尖端。每个间隔开的螺旋沟槽可包括螺旋切削刃，所述螺旋切削刃从尖端底部邻近于柄部顶部延伸到尖端顶部。所述尖端可包括切屑槽路径。每个切屑槽路径可以凹入于所述间隔开的螺旋沟槽中的两个之间，并且从所述尖端底部延伸到尖端顶部部分。所述主体可包括螺旋冷却剂通道，所述螺旋冷却剂通道从柄部底部处的入口延伸到柄部内部内、到尖端内部内、到尖端冷却剂孔口出口。所述冷却剂孔口出口可以邻近于所述切屑槽路径安置在所述间隔开的螺旋沟槽中，或安置在从所述尖端顶部向下延伸到所述切屑槽路径的释放表面中。所述冷却剂孔口出口可以与所述尖端顶部间隔开。
