Threading Solutions Overview
This document provides detailed specifications and recommendations for threading solutions, particularly focusing on internal threads as small as M2 x 0.4 (1-64 UN). These solutions are ideal for machining difficult materials where taps typically break. The tools feature 3 flutes with 3 teeth each, allowing for thread depths up to 3 times the diameter (3 x D) and offer short machining times due to high cutting speeds. They are economical for short threads.

Specifications

• Minimum Thread Size: M2 x 0.4
• Thread Depth: Up to 3 x D
• Flutes: 3 with 3 teeth each
• Materials: Suitable for difficult-to-machine materials

Metric and American Thread Dimensions
The document lists various thread sizes, pitches, and recommended drill sizes with hole tolerances for both metric and American UNC/UNF standards. For example, the metric sizes range from M2.5x0.45 to M12x1.75, while American sizes include No.6-40 to 7/16”-20.

Recommended Cutting Speeds and Feeds
Cutting speeds and feeds are recommended for different materials such as unalloyed steel, stainless steel, austenitic, and aluminum alloys. The document specifies the hardness in Brinell (HB) and provides coated feed rates for various materials.

Software and Tools
The TM Gen software is highlighted as a tool for automatically selecting the right tool for applications and generating thread milling programs (G-code) for CNC machinery. The latest version includes the entire MilliPro line.
