Product Description
Conquer your most challenging deep-hole threading applications with our Extra Long (100L) Solid Carbide 3-Teeth Thread Mill. Designed for precision CNC machining, this tool bridges the gap between reach and stability, making it the perfect choice for Hardened Steel (45-65 HRC) components.
Why Choose the "3-Teeth" Design for Deep Holes?
When machining deep threads with a long tool (100mm+), tool deflection (vibration) is the biggest enemy.
Vs. Single Point: The 3-Teeth design is 3x faster, reducing cycle time significantly.
Vs. Full Profile: It generates significantly less cutting force than a full-length thread mill. This reduction in pressure is vital when using an extra-long shank, ensuring the tool doesn't chatter or break inside the workpiece.
Engineered for Performance:
Extended Reach (100L): The 100mm total length allows for threading in deep pockets, mold cavities, and engine blocks where standard length tools cannot reach.
ATNIS / AlCrN Coating: Our advanced multi-layer coating withstands the extreme temperatures generated when milling hardened steel, preventing thermal cracking and extending tool life.
Versatile 60° Profile: Suitable for creating both ISO Metric and UN Unified threads with a standard 60-degree angle.
Chip Evacuation: The 3 or 4 flute design (depending on diameter) ensures efficient chip removal, preventing chip recutting in deep holes.
Application Scenarios:
Deep mold cavities (Plastic injection molds, Die casting).
Automotive engine parts (Quenched steel components).
Aerospace components requiring deep thread reach in hard alloys.
FAQ
Q: Why use a 3-Teeth thread mill instead of a full profile one for deep holes?
A: For deep holes (100mm length), a full profile cutter creates too much side pressure, causing vibration and tool breakage. The 3-Teeth design reduces cutting forces, ensuring stability and precision even with the long overhang.
Q: Can this tool machine 60 HRC steel?
A: Yes, thanks to the ATNIS/AlCrN coating and premium solid carbide substrate, this tool is specifically designed for quenched steels ranging from 45 to 65 HRC.
Q: What is the advantage of the 100L length?
A: The 100mm total length allows the tool to clear clamps, fixtures, or reach the bottom of deep mold cavities that standard 50mm or 75mm tools cannot reach.
