    • A tubing connector for synthetic or composite tubing includes an integral crimp ring. The crimp ring permitting the tubing connector to be rotated in the tubing after the crimp ring is crimped. The integral crimp ring simplifies and facilitates installation of the tubing connector and ensures accurate crimping for more consistent results and fewer leaky connections. A reaming tool enlarges and bevels the open end of the tubing to facilitate the insertion of the tubing connector into the tubing. The reaming tool has a guide screw so that the open end of the tubing is automatically drawn towards cutters on the tool when the guide screw is rotated in the tubing. The advantage is a perfect bevel and an accurate expansion with very little effort.
    • 用于合成或复合管材的管接头包括整体式压接环。 在压接环压接之后,压接环允许管连接器在管道中旋转。 整体式压接环简化并便于管道连接器的安装,并确保精确的压接以获得更一致的结果和更少的泄漏连接。 扩孔工具可扩大并斜切管道的开口端,以便将管道连接器插入管道。 铰孔工具具有导向螺钉,使得当导向螺杆在管道中旋转时,管道的开口端自动地被拉向工具上的切割器。 优点是完美的斜面和精确的扩展,很少的努力。

    • A reamer is provided with substantially helical extending carbide-bladed teeth by forming a reamer body having roughly shaped helical teeth thereon along the front face of each tooth a groove extending rectilinearly lengthwise and obliquely to the reamer axis, inserting into each such groove a small straight carbide strip shaped to fit snugly within the groove, the height of the strip being such that its upper end projects radially, over its whole length, above the tooth end and also beyond the extended diameter of the reamer, such strip also extending obliquely of the reamer axis, and subjecting each such strip to a grinding operation in which its upper end projecting beyond the reamer diameter is first rounded off to conform to the reamer diameter and a first cutting edge is formed at the leading edge thereof, and then the end portion of the strip is separately ground to produce a main cutting edge inclined at an angle to said first cutting edge in the direction of said reamer axis.
    • 通过在每个齿的前表面上形成具有大致呈螺旋形的螺旋齿的扩孔器主体,该铰刀主体沿纵向和纵向延伸至扩孔器轴线,该凹槽沿纵向和纵向延伸到每个这样的凹槽中, 硬质合金条被成形为紧密地配合在槽内,该条带的高度使得其上端在其整个长度上径向突出,在齿端之上并且也超过扩孔器的延伸直径,这样的条也倾斜地延伸 扩孔器轴线,并且对每个这样的带材进行磨削操作,其中其上端突出超过扩孔铣刀直径的研磨操作首先被倒圆以符合扩孔器直径,并且在其前缘处形成第一切削刃,然后端部 分开地研磨以产生沿所述铰刀轴线的方向与所述第一切削刃成一角度倾斜的主切削刃。
