Our JIS Straight Flute Taps are the workhorse of the precision tool industry.
Substrate Options: * HSS-M2 (AISI M2): The industry standard for general engineering, offering a perfect balance of toughness and wear resistance.
HSS-E M35 (5% Cobalt): Enhanced with Cobalt to handle higher heat and tougher materials like stainless steel or alloy steels.
Bright Finish (Uncoated): The precision-ground, polished surface provides the sharpest cutting edge possible. This prevents "tearing" of threads in softer materials and ensures high-precision fit according to JIS 6H standards.
JIS B 4430 Standard: Specifically designed with Japanese shank and square dimensions to fit seamlessly into Japanese-made tap wrenches and CNC collets (e.g., NT, BT, and HSK holders).
Multi-Purpose Design: The straight flute design is suitable for both Through-Holes and Blind Holes. It is especially effective in materials that produce short chips, such as Cast Iron, Brass, and Bronze.
| Size | Pitch (P) | JIS Standard | Overall Length (L) | Thread Length (ℓ) | Shank Ø (ds) | Square (K) |
| M2 | 0.40 | JIS | 40 mm | 9 mm | 3.0 mm | 2.5 mm |
| M3 | 0.50 | JIS | 46 mm | 18 mm | 4.0 mm | 3.2 mm |
| M4 | 0.70 | JIS | 52 mm | 20 mm | 5.0 mm | 4.0 mm |
| M5 | 0.80 | JIS | 60 mm | 22 mm | 5.5 mm | 4.5 mm |
| M6 | 1.00 | JIS | 62 mm | 24 mm | 6.0 mm | 4.5 mm |
| M8 | 1.25 | JIS | 70 mm | 30 mm | 6.2 mm | 5.0 mm |
| M10 | 1.50 | JIS | 75 mm | 32 mm | 7.0 mm | 5.5 mm |
| M12 | 1.75 | JIS | 82 mm | 38 mm | 8.5 mm | 6.5 mm |
| M16 | 2.00 | JIS | 95 mm | 45 mm | 12.5 mm | 10.0 mm |
| M20 | 2.50 | JIS | 105 mm | 50 mm | 15.0 mm | 12.0 mm |
| M30 | 3.50 | JIS | 135 mm | 56 mm | 23.0 mm | 17.0 mm |
Cast Iron & Brass: The straight flute is the best choice for these "short-chip" materials, preventing the clogging that often happens with spiral flutes.
General Maintenance: Essential for repair shops working on Japanese automotive (Toyota, Honda, Nissan) or heavy machinery components.
Mild Steel & Non-Alloy Steel: Optimized for materials with tensile strengths up to 800 N/mm².
Flexible Usage: Can be used in sets (Taper, Plug, Bottoming) for manual tapping or as a single tap in automated drilling machines.
Shockproof Retail Tubes: Every tap is vacuum-sealed and housed in a durable Rose-Box plastic tube, ensuring the cutting edges remain factory-sharp.
Corrosion Protection: Treated with industrial-grade anti-rust oil for a 36-month shelf life, protecting your inventory during sea freight to any global port.
OEM Customization: Since 1997, we have provided High-Definition Laser Marking (Logo + Size + Material + JIS) for international distributors.
Q: Is the JIS shank the same as the DIN shank?
A: No. JIS taps usually have a larger shank diameter for smaller sizes compared to DIN. For example, a JIS M6 tap has a 6.0mm shank, while a DIN 371 M6 also has 6.0mm, but the square (K) and total length differ. Always check the holder compatibility.
Q: Why choose "Bright Finish" instead of a coating?
A: Coatings can sometimes slightly round the very tip of a cutting edge. For manual tapping or precision threading in non-ferrous metals (like Aluminum or Brass), the "Bright Finish" offers a sharper cut and a cleaner thread profile.
Q: Can I buy these in 3-piece sets?
A: Yes. We offer them as individual taps or as full 3-piece sets (Taper, Plug, Bottoming) to distribute the cutting load during manual operations.
