Mastering Thread Milling at T&D Specialties
Welcome to the T&D Specialties blog! Today, on March 17, 2025, we’re excited to explore thread milling—a key skill we’ve perfected since 1996. If you’re wondering how T&D Specialties crafts precise threaded parts for aerospace and medical industries, let’s dive into the details!
Understanding Thread Milling Basics

Thread milling involves using a spinning tool guided by computers to cut threads into materials with great accuracy. Unlike older tapping methods, it works well for both inside and outside threads across different materials. At T&D Specialties, we excel at this process, delivering reliable results.
Our Expert Thread Milling Techniques
We adapt thread milling to fit each project’s needs. Here’s how we do it:
- Single-Point Thread Milling: This method creates smooth, large, or custom threads effortlessly.
- Multi-Tooth Thread Milling: It speeds up work for big orders, perfect for our 25–25,000+ piece runs.
- Helical Interpolation: Using indexers, we craft small accurate threads quickly on 3 sides of a small part in 1 setup, holding multi sided parts in our product tool like our Micro Vise.

Our advanced machines and skilled team adjust tools and speeds, handling materials like aluminum or titanium with ease.
Latest Trends in Thread Milling
Meanwhile, thread milling is evolving. A report predicts the market will grow to $28.67 billion by 2033, thanks to automation. Another study highlights thread milling improvements, boosting thread quality—check it out here. These trends guide our cutting-edge approach.
Real Success with Thread Milling
For example, we recently used thread milling to make flat bottom threaded holes, hitting micron-level precision and cutting production time by 20%. This shows our ability to meet tough demands.
