Precision Threading for Tough Metals
Product Overview
The Metric Solid Carbide Single-Point Thread Mill is a high-precision cutting tool designed for thread milling in steel and other tough materials. Crafted from ultra-fine grain tungsten carbide, this tool offers superior hardness, heat resistance, and durability, making it ideal for threading 45# steel, stainless steel, P20 tool steel, and gray cast iron.
With its single-flute (single-point) design, this thread mill provides maximum control, reduced tool pressure, and the ability to produce internal or external threads with excellent surface finish. It is widely used in aerospace, automotive, mold making, and general machining, especially when thread accuracy and tool life are critical.
Key Features
Thread Type: Metric
Material: Premium solid tungsten carbide for extreme wear resistance
Design: Single-flute (single-point) for low cutting force and precision threading
Versatile Threading: Capable of internal and external thread milling
High Accuracy: Suitable for tight-tolerance, high-finish requirements
Applications
hread milling in medium to hard steels, including:
45# carbon steel
304 / 316 stainless steel
P20 mold steel
gray cast iron
Commonly used for:
Mold components
Machinery parts
Threaded holes in die casting or CNC milled parts
Compatible with CNC machining centers, tapping centers, and milling machines
Advantages
High-Precision Thread Profiles – Excellent pitch accuracy and finish
Low Cutting Pressure – Ideal for thin-walled or heat-sensitive parts
Flexible Threading – Use one tool for multiple thread diameters (via helical interpolation)
Improved Tool Life – Withstands high temperatures and tough materials
No Chip Jamming – Open single-flute design promotes clean evacuation
Usage Recommendations
Always match the thread profile to the proper G-code or thread milling cycle
Use appropriate coolant or MQL for stainless and heat-resistant materials
Adjust spindle speed and feed based on material hardness and thread pitch
Use climb milling for better surface finish in hardened steels
