Fast and Reliable Threading in Tough Metals
Product Overview
The Metric Solid Carbide Triple-Flute Thread Mill is a robust, high-efficiency threading solution engineered for cutting internal and external threads in difficult-to-machine materials. Designed specifically for steel applications, this tool performs exceptionally well on 45# carbon steel, stainless steel (304/316), P20 mold steel, and cast iron, delivering both speed and precision.
Constructed from premium tungsten carbide, this thread mill features a three-flute cutting geometry that provides balanced cutting forces, superior chip evacuation, and higher feed rates compared to single-flute tools. It’s ideal for production threading, precision molds, and high-strength components, where consistency and tool life are critical.
Key Features
Thread Standard: Metric threads (M-series)
Material: Ultra-hard solid tungsten carbide for maximum durability
Flute Design: Triple-flute geometry for enhanced cutting speed and tool stability
Thread Types: Internal & external threads via helical interpolation
Excellent Chip Control: Suitable for long, blind, and deep-hole threading
Applications
hread milling in medium to hard steels, including:
45# medium carbon steel
304 & 316 stainless steels
P20 pre-hardened mold steel
Gray cast iron and ductile iron
Other alloyed and structural steels
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-speed threading with excellent dimensional consistency
Clean thread finishes even in tough or abrasive steels
Strong and stable tool body resists deflection in high-feed operations
Reduced cycle time compared to single-flute alternatives
Ideal for mass production and precision applications alike
Usage Recommendations
Use helical interpolation G-code for thread paths (G02/G03)
Apply proper coolant or mist lubrication for longer tool life
Match RPM and feed rate to material type and thread pitch
For blind holes, ensure proper clearance for tool overrun
