Why buyers pick this one

Upward Chip Evacuation: The engineered spiral flute acts as a lifting auger, continuously pulling curled chips out of the workpiece. This makes it the only safe and reliable choice for tapping blind holes where chips cannot fall through.
Optimized for Machine Tapping: Designed to withstand the continuous torque and speed of CNC machines and automated tapping arms, reducing cycle times and minimizing tool changeovers.
Premium HSS Integrity: Crafted from top-tier High-Speed Steel to maintain sharp cutting edges under high friction, providing long-lasting durability in both ferrous and non-ferrous metals.
Precision Ground Threads: Each tap is CNC-ground to exact international thread tolerances, guaranteeing that your finished fasteners will assemble perfectly without cross-threading or binding.
Complete OEM Customization: Build your cutting tool brand with us. We offer specialized surface coatings (such as Titanium Nitride for extra wear resistance), custom laser marking on the shank, and secure plastic tube packaging for retail display.

Overview

Maximize your production efficiency and eliminate tap breakage with the premium Spiral Flute Machine Taps from Shanghai Daoge Xiaoman Tools Co., Ltd. Engineered specifically for continuous use in CNC machining centers, drill presses, and automated tapping equipment, these cutting tools are the ultimate solution for blind hole threading. Manufactured from high-grade High-Speed Steel (HSS), the precisely ground spiral flutes effectively draw metal chips upward and out of the hole, preventing the dangerous chip packing that destroys standard straight-flute taps. Whether you are cutting standard Metric or Imperial (UNC/UNF) threads in carbon steel, aluminum, or stainless steel alloys, our machine taps deliver exact tolerances and exceptionally smooth thread profiles.
