Knurling Tool Accessories for Lathe Operations
Knurling tool accessories — primarily replacement knurling wheels and associated wheel holders — allow knurling tools to be maintained, reconfigured, and adapted for a range of workpiece materials and knurl patterns. Knurling wheels wear with use and must be replaced to maintain consistent pattern quality and avoid rough or incomplete impressions on workpieces. Having replacement wheels for each pattern type and pitch used in the workshop prevents production delays when a worn wheel needs changing mid-batch. AIMS stocks knurling wheels and holders compatible with common knurling tool systems used on CNC and manual lathes.
Knurling Wheel Patterns
Knurling wheels are available in three standard pattern types. Straight wheels produce parallel lines running axially along the workpiece — used for grip surfaces on round components and for creating mechanical interference fits. Diagonal wheels produce lines running at a helical angle, available in left-hand (L) and right-hand (R) helix variants. Diamond patterns are produced by combining left-hand and right-hand diagonal wheels in a straddle or bump knurling configuration. The pitch of the knurl — the spacing between adjacent lines or diamond peaks — is selected based on workpiece diameter, required grip texture, and functional requirements. Finer pitches suit precision instruments and adjustment knobs; coarser pitches provide more aggressive grip for heavy hand-operated components.
Wheel Materials and Bore Sizes
Standard knurling wheels for steel and aluminium workpieces are made from hardened high-speed steel or alloy tool steel. Carbide knurling wheels are specified for harder workpiece materials including stainless steel, hardened steel, and titanium alloys, where standard HSS wheels wear rapidly and produce poor pattern definition. Wheel bore diameter must match the pin or axle in the knurling tool holder — common bore sizes are 6mm, 8mm, and 12mm, though some brands use proprietary dimensions. Always confirm the bore size required for your specific tool before ordering replacement wheels to avoid returning incorrect stock.
Maintaining Knurling Wheels
Knurling wheels should be kept clean of chips and swarf between uses — built-up material in the pattern causes tracking errors on subsequent operations. A stiff brush cleans wheels effectively between cuts. Apply cutting fluid to the wheel and workpiece during knurling to reduce friction, improve pattern formation, and extend wheel life. Inspect wheels regularly for chipped or cracked teeth — a damaged wheel produces inconsistent pattern depth and should be replaced before it damages the workpiece surface or causes the pattern to track incorrectly.
