Machine Tap DIN 374 Form C HSSE - FG 7.9 x 26

• Cut or restore internal threads in pre-drilled holes in maintenance work, prototyping, and controlled small batch production.
• Select the tool by the thread designation and standard stated in the product name and keep the tool square to the bore axis.
• Use cutting fluid matched to the material to reduce friction and support chip evacuation from the flutes.
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Verify the workpiece preparation before you start and stop if torque increases unexpectedly.

• Controlled internal thread cutting for workshop and maintenance tasks.
• Supports clean thread start when you keep the tap aligned and use suitable lubrication.
• Fits common tapping workflows for through holes and blind holes as stated in the product name.
• Useful for repair tapping when you need manual feel and torque feedback.

• Not suitable for very hard or highly abrasive materials where carbide tooling is required.
• Not suitable for high volume production tapping where cycle time is critical.

1. Confirm the thread designation in the product name and prepare a suitable core hole for that thread system.
2. Chamfer the hole edge and remove burrs so the tap starts cleanly.
3. Secure the tap in a suitable holder and align it square to the bore axis.
4. Apply cutting fluid matched to the material and start with steady torque.
5. Advance with controlled feed and briefly back off when torque rises to clear chips.
6. Continue until the required depth is reached, then reverse out fully.
7. Clean the thread and verify fit with a matching fastener or gauge.

How do you select the correct tool variant from the product name? Match the thread designation and standard stated in the product name to your drawing or the mating fastener. Confirm whether you need an internal or external thread tool and whether the thread is left hand or right hand. How do you reduce the risk of cross-threading at the start? Prepare a clean chamfer and keep the tool axis aligned with the hole or rod axis. Start with controlled torque and stop if the tool tilts or binds. Where can you find technical guidance for machine taps? Technical information machine taps as PDF What role does cutting fluid play during thread cutting? Cutting fluid reduces friction and heat at the cutting edges and it supports chip evacuation from the flutes. Choose a fluid matched to your workpiece material and process. What does HSSE mean in practice? HSSE indicates cobalt alloyed high speed steel, often selected for higher thermal loads. Where can you find more product and application information in a catalog?
