BEYOND TR20 Trapezoidal Thread Taps
High-Precision HSS Lead Screw Tapping Solutions | Pitches 2.0mm to 6.0mm
What makes BEYOND TR20 taps ideal for heavy-duty lead screws?
The BEYOND TR20 series comprises professional-grade Trapezoidal Metric Thread Taps designed specifically for creating high-torque transmission threads. Unlike standard triangular threads, the TR profile is engineered for power screws and lead screw applications where high axial force and smooth motion are required. Manufactured from premium High-Speed Steel (HSS), these taps provide exceptional wear resistance and precision in carbon steel, alloy steel, and stainless steel workpieces.

Why should I choose HSS Trapezoidal taps for industrial machining?
- ✅ Straight Flute Design: Optimized for through-hole tapping with maximum tool rigidity to prevent breakage during high-torque cycles.
- ✅ Premium HSS Material: Our taps use advanced metallurgy to maintain cutting edge sharpness under high thermal loads.
- ✅ Precision Ground Geometry: Ensures accurate 30° flank angles for smooth lead screw engagement and low friction.
- ✅ Wide Pitch Availability: From TR20x2 for fine adjustment to TR20x6 for rapid travel power screws.
What are the technical specs for the TR20 series?
| Model | Metric Pitch | Imperial Equiv. | Drill Size (mm) |
|---|---|---|---|
| TR20x2 | 2.0 mm | ~12.7 TPI | 18.1 mm |
| TR20x3 | 3.0 mm | ~8.46 TPI | 17.2 mm |
| TR20x4 | 4.0 mm | ~6.35 TPI | 16.3 mm |
| TR20x6 | 6.0 mm | ~4.23 TPI | 14.5 mm |
Recommended Cutting Parameters
For TR20 threads, slower speeds are essential for accuracy:
- Rotation Speed: 3 - 10 m/min (depending on material hardness).
- Coolant/Lubrication: High-pressure sulfur-based cutting oil is strongly recommended.
- Tapping Method: Rigid tapping on CNC or high-torque radial drills.
Product Applications
Ideal for machining components for industrial valves, 3D printer Z-axis rods, CNC lathe lead screws, and heavy-duty mechanical jacks where power transmission is required.
Machine Compatibility
Fully compatible with standard square-drive tapping chucks, Morse taper adapters, and professional CNC machining centers (VMC/HMC).

Why buy BEYOND Trapezoidal Taps?
We combine state-of-the-art Chinese manufacturing with rigorous ISO quality standards to deliver industrial tooling that rivals global brands at a fraction of the cost. Our TR series is trusted by technicians worldwide for power transmission projects.
Frequently Asked Questions
A: TR threads are Metric Trapezoidal (30° angle). ACME is Imperial (29° angle). While similar, they are not interchangeable. Check your design requirements first.
A: For large TR20 pitches (like 5.0 or 6.0), using a set or pre-boring the diameter accurately is necessary to reduce tool load.
A: Our standard HSS series is bright finish for maximum sharpness. TiN or TiAlN coatings are available for high-volume abrasive material machining.
HSS-E (Cobalt) offers higher heat resistance than standard HSS. Always ensure high-torque lubricant is used to prevent "welding" of chips to the trapezoidal profile.
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.
