Technical Data

A Knurling Tool Holder Quick Acting – 2 Knurl is an essential device used in metalworking and machining operations for producing textured or patterned surfaces on cylindrical workpieces. The process of knurling involves impressing a series of uniform diamond or straight patterns onto the surface of a rotating workpiece, typically on a lathe. These patterns not only enhance the aesthetic appeal of the component but also improve grip and functionality, making knurled surfaces common in tool handles, knobs, and mechanical parts that require manual adjustment.

This particular model, a quick-acting 2-knurl holder, is designed for efficiency, precision, and durability. It features two opposed knurling wheels (or rollers) mounted on a rigid steel body. These two wheels simultaneously press against the rotating workpiece from opposite sides, forming an even and balanced knurled pattern. The double-wheel configuration eliminates lateral pressure on the lathe spindle and prevents deflection of the workpiece, resulting in a cleaner, more accurate knurl pattern. The body of the Knurling Tool Holder is typically made from high-grade alloy steel or hardened tool steel, providing exceptional strength, wear resistance, and rigidity.

The holder is precision-machined to ensure perfect alignment of the knurling wheels and smooth operation. The two knurling wheels are mounted on hardened pins or axles with high-quality bearings that allow free and smooth rotation under heavy load. The quick-acting mechanism is one of the defining features of this tool. It allows the operator to quickly engage or disengage the knurling wheels with a simple lever or screw adjustment. This saves significant setup time compared to conventional fixed knurling tools, especially in production environments where multiple parts are being knurled consecutively.

The quick-acting feature also ensures consistent pressure application, reducing operator fatigue and ensuring repeatable results. In operation, the tool holder is clamped securely into the lathe’s tool post or turret. Once the workpiece begins rotating, the operator engages the knurling wheels by turning the quick-acting lever or adjusting screw, pressing both wheels simultaneously against the workpiece surface. The cross-feed of the lathe then moves the tool along the workpiece, forming a precise and uniform knurling pattern. The dual-wheel design ensures that forces are balanced, eliminating the side thrust common with single-wheel knurling tools, thus protecting both the tool and the machine spindle.

The 2-knurl setup is versatile, as it can accommodate different types of knurl patterns — such as straight, diagonal, or diamond — depending on the knurl wheels installed. The wheels themselves are replaceable, allowing the user to switch between coarse, medium, and fine pitch patterns as needed. Common materials for the knurl wheels include high-speed steel (HSS) and carbide, chosen for their ability to withstand the high pressures and frictional heat generated during the knurling process.
