Carbide Tap series for High hardened material

Product catalog summary

Introduction
The document provides an overview of the Epoch Super Hard Tap and Epoch Hard Tap series, which are designed for machining high-hardness materials. It addresses challenges such as tap breakage and chipping during reverse rotation and introduces solutions offered by these products.

Specifications
The Epoch Super Hard Tap is suitable for materials with hardness between 50-60 HRC, while the Epoch Hard Tap is for materials with hardness between 35-50 HRC. Both series are available in sizes M3 to M12 with various pitches and thread lengths. The Epoch Hard Tap features a reverse-rotation cutting tooth shape to reduce load and minimize tooth clogging.

Recommended Cutting Conditions
For the Epoch Super Hard Tap, recommended cutting speeds are 2-5 m/min for 50-55 HRC and 1-3 m/min for 55-60 HRC. The Epoch Hard Tap is recommended at 3-6 m/min for 35-45 HRC and 2-4 m/min for 45-50 HRC.

Features and Benefits
The Epoch Super Hard Tap includes a cross-section design to minimize torque and chip clogging, a TH coating for heat and wear resistance, and a larger shank diameter for durability. The Epoch Hard Tap's reverse-rotation teeth help prevent chip clogging and reduce breakage.

Performance Comparison
Tests indicate that both the Epoch Super Hard Tap and Epoch Hard Tap offer stable machining with fewer instances of breakage and chipping compared to competitor products.

Recommended Pilot-Hole Drills
The document provides specifications for pilot-hole drills compatible with the taps, detailing dimensions such as flute length, overall length, and shank diameter.

Product Range
The series includes the Epoch Super Hard Tap for 50-60 HRC and the Epoch Hard Tap for 35-50 HRC, available in sizes M3 to M12.

Safety and Specifications
Specifications may change without notice for improvements. The document is printed with soy ink.

Conclusion
The Epoch Super Hard Tap and Epoch Hard Tap series offer advanced features for machining high-hardness materials, providing enhanced stability and efficiency in cutting operations.

Carbide Tap series for High hardened material-6

Reverse-rotation cutting tooth shape The majority of tap breakage or chipping occurs when the tap is reversely rotated. During reverse rotation, not only is the direction of torque becomes reversed and loads placed on the tap, but also clogging of the teeth by chips is more likely, leading to breakage and chipping. Epoch Hard Taps are equipped with reverse-rotation cutting tooth shape to reduce the load during reverse rotation and minimize tooth clogging by chips, enabling stable tapping. No tooth clogging by chips during reverse rotation, enabling stable machining. Forward rotation During reverse...

1. Cautions regarding handling (1) When removing the tool from its case (packaging), be careful that the tool does not pop out or is dropped. Be particularly careful regarding contact with the tool flutes. (2) When handling tools with sharp cutting flutes, be careful not to touch the cutting flutes directly with your bare hands. 2. Cautions regarding mounting (1) Before use, check the outside appearance of the tool for scratches, cracks, etc. and that it is firmly mounted in the collet chuck, etc. (2) If abnormal chattering, etc. occurs during use, stop the machine Immediately and remove the...
