TR24 TRAPEZOIDAL MACHINE TAPS
Professional Lead Screw Threading | HSS-Co Cobalt Series
High-Precision TR24 Trapezoidal Threading
The BEYOND TR24 series is specifically engineered for cutting high-torque trapezoidal threads (ISO 2901/2903 standard). Often used for lead screws, transmission shafts, and heavy-duty vice equipment, these TR24 machine taps provide the durability required for deep-thread engagement in tough materials. Whether you are machining Right-Hand (RH) or Left-Hand (LH) threads, BEYOND ensures a smooth, vibration-free tapping experience.
Available Models & Specs
| Model Number | Thread Type | Pitch (mm) | Direction |
|---|---|---|---|
| TR24 X 2 / TR24 X 3 | Trapezoidal | 2mm / 3mm | Right Hand |
| TR24 X 4 / TR24 X 5 | Trapezoidal | 4mm / 5mm | Right Hand |
| TR24 X 2L / 3L / 4L / 5L | Trapezoidal | 2-5mm | Left Hand (LH) |
Decoding the Model: TR 24 X 3 L
- TR: Trapezoidal Thread (30° thread angle, ISO standard).
- 24: Nominal Diameter (24mm).
- X 3: Thread Pitch (3mm distance between threads).
- L: Denotes Left-Hand rotation (omit for Right-Hand).
Industrial Grade Material & Slot Design
HSS-Co (M35 Cobalt Steel): Our TR24 taps are manufactured from High-Speed Steel with 5% Cobalt. This significantly increases red-hardness and wear resistance, allowing for tapping in stainless steel, alloy steel, and cast iron without losing the cutting edge.
Straight Flute vs. Spiral Flute: The straight flute design provides maximum strength for through-hole applications, while the wide chip space ensures that large trapezoidal metal chips are broken and cleared efficiently to prevent tool breakage.
Recommended Cutting Parameters
For optimal tool life in Medium Carbon Steel:
- Cutting Speed (Vc): 5 - 10 m/min (Due to high friction of Trapezoidal profiles)
- Rotation Speed (RPM): Calculate using $N = \frac{Vc \times 1000}{\pi \times 24}$
- Lubrication: High-sulfur tapping oil or heavy-duty paste is mandatory.
Metric vs. Imperial (ACME) Comparison
Note: TR (Metric Trapezoidal) and ACME (Imperial) are not interchangeable due to different thread angles (30° vs 29°).
| Feature | Metric TR24 (This Product) | Imperial ACME Approx. |
|---|---|---|
| Diameter | 24.0 mm | 0.945" (~15/16") |
| Thread Angle | 30° | 29° |
Global Machinist Reviews
"Excellent for Lead Screws"
"Used the TR24x5 LH for a custom lift mechanism. The thread is clean and the Cobalt steel holds up well."
- Robert T. (UK)
"Top quality from China. The TR24x3 Right Hand tap cut through 4140 steel like butter with proper oil."
- Marco S. (Italy)
"Hard to find TR24 LH taps at this price. BEYOND is now my main supplier for trapezoidal tools."
- Alan F. (Australia)
Frequently Asked Questions
Q: Can I use this tap by hand?
A: While possible with a large tap wrench, TR24 has high cutting resistance. We recommend use on a lathe or CNC with low RPM and high torque.
Q: What is the pre-drill size for TR24x5?
A: For TR24x5, the recommended drill diameter is 19.5mm. (Diameter - Pitch = Hole Size).
Q: Is this suitable for Stainless Steel?
A: Yes, the HSS-Co (Cobalt) material is designed for stainless and other tough alloys.
Quick Tip: Choosing the Right Material
HSS (Standard): Best for aluminum, copper, and low-carbon steel. Cost-effective but wears faster on hard metals.
HSS-Co (This Series): 5% Cobalt added. Superior heat resistance. Necessary for Stainless Steel, High-Tensile Steels, and continuous production runs.
