The knurling process displaces metal at the workpiece surface rather than cutting it away, which means the workpiece diameter increases slightly after knurling — this must be accounted for when turning to pre-knurl diameter on close-tolerance components. AIMS stocks knurling tools for manual and CNC lathe applications from professional tooling brands.\u003c\/p\u003e\n\u003ch3\u003eStraddle Knurling Tools\u003c\/h3\u003e\n\u003cp\u003eStraddle (scissor) knurling tools position two wheels above and below the workpiece simultaneously, applying equal and opposing radial forces. This balanced force application eliminates the side-loading on lathe spindle bearings that is a concern with single-side bump knurling — making straddle knurlers the preferred type for lighter lathes, longer or slender workpieces that could deflect under one-sided load, and CNC turning operations where maintaining spindle load within machine specifications is important. The opposing wheels are set to matching pitch and pattern to produce a consistent diamond or straight pattern across the full knurl width. Quick-change straddle knurling holders for standard quick-change toolposts allow fast wheel changes without removing the holder from the machine.\u003c\/p\u003e\n\u003ch3\u003eBump Knurling Tools\u003c\/h3\u003e\n\u003cp\u003eBump knurling tools apply a single pair of wheels to the workpiece from one side, requiring machine rigidity to handle the significant side-loading forces generated. Bump knurling is the traditional method on manual engine lathes and is appropriate for short, rigid workpieces on robust machines with well-supported spindle bearings. The tool is advanced radially into the workpiece while traversing along the axis to produce a full-length knurl. Multiple passes are often needed to achieve full pattern depth, particularly on harder materials. The mechanical simplicity of bump knurling tools makes them cost-effective and easy to set up for occasional knurling operations on existing manual lathes without dedicated toolpost accessories.\u003c\/p\u003e\n\u003ch3\u003eCut Knurling\u003c\/h3\u003e\n\u003cp\u003eCut knurling tools use a sharp-edged wheel to cut the pattern into the workpiece surface rather than displacing material. This produces a consistent, accurate pattern without diameter growth and is preferred for harder materials where displacement knurling is difficult, for close-tolerance workpieces where diameter increase cannot be accommodated in the drawing, and for applications requiring very fine, precise pattern geometry. Cut knurling is commonly used in CNC turning operations for production components requiring controlled, repeatable pattern depth and geometry across a batch.\u003c\/p\u003e\n\u003cp\u003eFor knurling tool selection, pattern specifications, or replacement wheels, \u003ca href=\"\/en-nz\/pages\/contact-us\"\u003econtact our team\u003c\/a\u003e.\u003c\/p\u003e","products":[{"product_id":"maxigear-3-4-x-3-8-pivot-head-knurling-tool","title":"Maxigear 3\/4\" x 3\/8\" Pivot Head Knurling Tool","description":"\u003cdiv style=\"max-width:680px;width:100%;padding:12px 0;font-family:Arial,sans-serif;\"\u003e\n\u003cdiv style=\"display:flex;align-items:flex-start;justify-content:space-between;border-top:1px solid #e0e0e0;border-bottom:1px solid #e0e0e0;padding:16px 0;margin-bottom:24px;\"\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e◆\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003e3\/4\"\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e●\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003eMaxigear\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex:1;padding:0 12px;text-align:center;\"\u003e\n\u003cdiv style=\"font-size:24px;color:#333;margin-bottom:6px;line-height:1;\"\u003e▲\u003c\/div\u003e\n\u003cdiv style=\"font-size:14px;font-weight:500;color:#333;line-height:1.4;\"\u003eTrade workshop pick\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size:14px;line-height:1.6;color:#444;margin:0;\"\u003eThe Maxigear 3\/4\" x 3\/8\" Pivot Head Knurling Tool gives trades and workshops a dependable, fit-for-purpose hand tool.
