BEYOND HSS Dual Lathe Knurling Wheels Pair (30° & 45° Helix Angles, Pitch P0.3 - P3.0)
1. Product Overview
Which knurling wheels are best engineered for forming precise DIN 82 diamond and cross-hatch grip profiles on CNC turning centers and manual engine lathes?
The BEYOND Precision HSS Form Knurling Wheel Series is manufactured specifically for cold pressure displacement knurling operations on steel, stainless steel, brass, aluminum, and titanium workpieces. Each set is delivered as a perfectly matched pair (BL Left-Hand + BR Right-Hand spiral patterns) in either 30° or 45° helix angles to produce male diamond (RGE/RAA) surface textures with crisp tooth definition.
Constructed from premium vacuum heat-treated High-Speed Steel (HRC 63-65) with fully ground tooth profiles, BEYOND knurling rolls resist tooth chipping and galling under high pressure. Available in four outer diameter configurations—10x4x4mm (0.39"x0.16"x0.16"), 15x6x4mm (0.59"x0.24"x0.16"), 20x8x6mm (0.79"x0.31"x0.24"), and 20x10x6mm (0.79"x0.39"x0.24")—covering pitch ranges from fine P0.3mm to heavy-duty P3.0mm.
2. Key Features
- Precision Matched Pairs (BL + BR Set): Supplied as 1 Left-Hand and 1 Right-Hand wheel pair to automatically generate symmetrical DIN 82 RGE raised diamond patterns in a single pass.
- Optimum 30° and 45° Helix Angles: 30° helix wheels produce standard diamond knurls with smooth material displacement; 45° helix wheels feature sharp cross-cutting tooth geometry for quick initial penetration on tough steels.
- Premium Vacuum Hardened HSS (HRC 63-65): Full CNC tooth grinding delivers ultra-sharp ridge tips and polished gullets, preventing tooth deformation and extending tool life under heavy radial loads.
- Full Pitch Capability (P0.3 to P3.0): Covers micro-pitch knurling for optical/medical tools up to heavy industrial grips for machine handles and oil rig hardware.
- Standardized Bore Dimensions: Precision bore tolerances (+0.010 / +0.020mm) fit smoothly onto standard dual-wheel lathe knurling holder pivot pins without side wobble.

"Cleanest diamond knurls I've ever produced on 304 Stainless!"
Ordered the 20x8x6mm 30° pitch P1.0 pair for my Haas ST-10. Mounted them on my dual wheel holder, used sulfurized cutting oil, and got sharp, burr-free diamond knurls on stainless handles. Tooth tips are super crisp.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
