Dorian Tool 73310121486 Scissor Straddle Knurler

Product Description

The DORIAN TOOL 73310121486 is a scissor and straddle type knurler designed for right-hand cut applications on a lathe. It measures 6-13/16 inches overall length by 2-1/2 inches overall width and handles a capacity range of 1/8 inch to 2-1/2 inch diameter workpieces. The tool mounts via a rectangle shank measuring 1 inch wide by 1 inch tall with a 5-inch shank length, making it compatible with standard lathe tool posts. Part of the SW4 Series, this knurler requires two knurl wheels and ships with both left-hand diagonal and right-hand diagonal knurl wheels included. It is the appropriate tool for machinists and toolmakers who need reliable, repeatable knurl patterns on turned parts.

This knurler is suited for use in machine shops, production turning operations, and maintenance environments where knurled grips, fastener textures, or press-fit surfaces are required. The scissor and straddle design applies balanced pressure to the workpiece, reducing part deflection compared to single-wheel bump knurlers. The 1/8-inch to 2-1/2-inch capacity range covers a wide variety of shaft and rod diameters common in general machining and custom part fabrication. Machinists working on manual or CNC lathes will find the rectangle shank straightforward to set up in a standard quick-change or lantern-style tool post.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with lathe tooling and safe machine operation. Power down and lock out the lathe before mounting or removing the knurler from the tool post. Ensure the shank is clamped securely and the knurl wheels are properly seated before engaging the workpiece. Follow the lathe manufacturer guidelines and applicable shop safety standards during setup and operation.
