Tungsten carbide deep hole boring tool also called deep hole boring head, divided into split type and combined type. Tungsten carbide deep hole boring tool head is one kind of deep hole boring tool cutter, involving: deep hole drills, deep rolling head, deep hole boring head. First drill hole drilling and rolling, finally bore (it should be rough boring, fine boring, rolled, and finally rolling, surface finish can be achieved after rolling 0.4μm).
The new tungsten carbide deep hole boring tool head is a three-blade BTA deep hole boring head, upper body fixed set with two boring bars and three cutting edges, bars and cutting edge at the same cylindrical surface of the outer edge. Tungsten carbide deep hole boring tool head is provided with two out crumbs mouth, mouth cavity under the debris semicircle extending forward 2-5mm. As a result of the chip work, the oil is fed from the boring bar outside, after the bars and cutting edge, fold back carrying the chips from the boring bar cavity discharge backwards to achieve a boring head and guide the cutting edge of the full cooling lubrication, on this basis, further freely super-hard cutting tool materials using cutting edge and the guide bar, in order to achieve high speed and precision of tungsten carbide deep hole boring tool.
