The specialized Spiral Point geometry at the cutting face continuously pushes chips

1. Introduction: The High-Hardness Specialist Our DIN 371/376 HSS-E M35 TiCN Coated Spiral Flute Taps are engineered for the most demanding blind-hole tapping environments. By combining a 5% Cobalt (M35) substrate with an advanced Titanium Carbo-Nitride (TiCN) physical vapor deposition (PVD) coating, these taps achieve a superior balance of toughness and extreme surface hardness. The 35° spiral flute geometry is optimized to mechanically lift chips out of blind holes, while

1. Introduction: The Ultimate Through-Hole Solution Our DIN 371/376 Nitrided Spiral Point Machine Taps, commonly referred to as Gun Taps, are the industry standard for high-speed, high-efficiency through-hole threading. This tap features a straight flute designed to be stronger than a spiral flute tap, while the specialised spiral point geometry at the cutting face continuously pushes chips forward and out through the bottom of the hole. This eliminates chip evacuation issues

1. Introduction: The Professional Blind Hole Solution The DIN 371/376 HSS-E M35 Spiral Flute Machine Taps are the definitive solution for high-speed, automated blind hole tapping. Featuring a precision-engineered 35° helix angle, these taps lift chips upward and out of the hole, preventing the catastrophic "chip-packing" that leads to tool breakage. Forged from premium M35 Cobalt Steel (5% Co), this series offers the thermal stability required for machining work-hardening

1. Introduction: The Blind Hole Specialist The DIN 371/376 HSS-E M35 Spiral Flute Machine Taps are engineered for high-efficiency threading in blind holes (holes that do not go all the way through). Featuring a 35° right-hand helix (spiral), these taps act like a drill bit for chips, lifting them upward and out of the hole to prevent clogging and tap breakage. Forged from premium M35 High-Speed Steel with 5% Cobalt (HSSE), these tools provide superior heat resistance and edge

1. Introduction: The Industrial Workhorse The M10 x 1.5 is the standard coarse thread size for medium-duty fasteners found in heavy machinery, automotive frames, and structural steel. Our DIN 352 Hand Tap Set is the preferred choice for manual threading where precision and tool longevity are paramount. By employing the classic 3-piece system—Taper, Plug, and Bottoming—users can manage the significant torque required to cut M10 threads in tough materials, ensuring a clean,

1. Introduction: The Universal M6 Standard The M6 x 1.0 is the most widely utilized metric fastener size globally, essential for automotive assembly, furniture manufacturing, and general machinery. Our DIN 352 M6 Hand Tap Set provides a professional-grade solution for creating high-precision internal threads in manual operations. By employing the traditional 3-piece sequence (Taper, Plug, and Bottoming), this set allows for gradual material removal. This is critical for

1. Introduction: The M4 Industrial Standard The M4 (M4 x 0.7) is a critical fastener size used extensively in automotive sensors, electrical enclosures, and light machinery. Our DIN 352 M4 Hand Tap Set is engineered to produce high-precision internal threads in manual operations. By utilizing the traditional 3-piece sequence (Taper, Plug, and Bottoming), this set allows users to form threads gradually. This is especially important for the M4 size, where the tool's core

1. Introduction In manual threading, the greatest cost is not the tool, but a broken tap inside an expensive workpiece. Our DIN 352 3-Piece Set is specifically engineered to mitigate this risk through a systematic material removal process: No.1 Taper Tap: Features a long lead-in chamfer that acts as a self-aligning guide, ensuring the thread starts perfectly vertical even in field repairs. No.2 Plug Tap: Refines the thread profile, distributing the cutting torque to prevent
