Balax 30074-000 Spiral Point Tap 10-32 Unf 3 Flute

Product Description

The BALAX 30074-000 is a spiral point plug tap designed for threading 10-32 UNF holes in a wide range of metals. Built from M42 grade powdered metal high-speed steel, it delivers consistent thread quality and extended tool life compared to standard HSS taps. The 3-flute spiral point geometry pushes chips ahead of the cutting action, making it well suited for through-hole tapping operations. With a thread limit of H4 and a bright uncoated finish, this tap is appropriate for general-purpose threading in both manual and machine tapping applications. It carries a right-hand thread direction and does not require coolant-through capability.

This tap is used for cutting 10-32 UNF threads in through-hole applications across a broad spectrum of materials including aluminum, brass, bronze, copper, magnesium, zinc, wrought aluminum alloy, carbon steel, and stainless steel. The plug chamfer style makes it a standard production and repair choice in machining, fabrication, and maintenance environments. It fits within the BALAX BX100 series and is sized for use with standard 10-32 tap holders and chucks in both hand and machine tapping setups.

Key Features

• 3-flute spiral point geometry pushes chips forward for clean through-hole threading
• Plug chamfer for general-purpose production tapping
• H4 thread limit for consistent oversize tolerance control
• Right-hand thread direction, compatible with standard tapping equipment
• Bright uncoated finish suitable for use across aluminum, steel, brass, copper, and stainless steel

Compatibility

Designed for through-hole tapping of 10-32 UNF threads in aluminum, brass, bronze, carbon steel, copper, magnesium, stainless steel, wrought aluminum alloy, and zinc. Part of the BALAX BX100 series.

Installation Notes

This tap is installed by machinists and maintenance technicians using standard tap wrenches, tapping heads, or CNC machine tool holders. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for 10-32 UNF threads before tapping. Apply appropriate cutting fluid for the material being threaded to promote chip evacuation and reduce tool wear. Do not reverse the tap under power to break chips, as this can cause tool breakage.
