Boring bar and boring tool with same

The invention relates to the field of machining tools of machine tools, in particular to a boring bar and a boring tool with the same. The boring bar comprises a core bar. A carbon fiber sleeve layeris coated on the outer peripheral surface of the core bar, and a coating sleeve for fixedly compressing the carbon fiber sleeve layer sleeves the outer peripheral surface of the carbon fiber sleeve layer. The boring bar and the boring tool have the advantages that the carbon fiber sleeve layer and the metal sleeve are arranged on the outer peripheral surface of the boring bar, accordingly, the stiffness of the integral boring bar can be reinforced, and deep-hole machining requirements on the boring bar can be met. 本发明涉及机床加工刀具领域，尤其涉及种镗杆及使用该镗杆的镗刀。镗杆包括芯杆，芯杆的外周面包覆有碳纤维套层，碳纤维套层的外周面套设有用于将碳纤维套层进行压紧固定的包覆套。本发明中的芯杆通过在镗杆的外周面布置有碳纤维套层和金属套使得整个镗杆的刚度得到加强，满足了镗杆深孔加工的要求。
