Machine Tap DIN 376 Form C 35° Spiral Flute HSSE - M 24 x 3.0

This tap is specifically designed for the challenges of cutting threads in blind holes. The key features that set it apart are:

• DIN 376: A standardized design for machine taps with a long shank, which ensures precise manufacturing and high stability for larger dimensions.
• Form C (2-3 thread chamfer): This short chamfer form is optimal for quickly cutting a full thread and facilitating chip evacuation.
• 35° Spiral Flute: The right-hand spiral geometry efficiently pushes chips up and out of the hole, preventing clogging and minimizing the risk of tool breakage.
• HSSE Material: High-Speed Steel with Cobalt (HSSE) offers superior hardness and hot hardness compared to conventional HSS, extending the tool's service life in demanding materials.

To achieve optimal results, follow this simple guide:

1. Step 1: Drill the correct pilot hole. Choose the correct pilot drill for your thread. For M 24 x 3.0, the suitable pilot hole diameter is 21.0 mm. Drill the hole to the desired depth.
2. Step 2: Clamp the tool. Securely and centrally clamp the machine tap in your machine's chuck.
3. Step 3: Prepare lubrication. The use of a suitable cutting fluid or lubricant is crucial to reduce friction and heat and to extend the tap's service life.
4. Step 4: Cut the thread. Begin the cutting process at a low to medium speed. Feed the tap slowly and without excessive pressure into the pilot hole. The right-hand spiral geometry ensures that chips are automatically evacuated from the hole.
5. Step 5: Retreat and clean. Once the desired thread depth is reached, carefully and straightly retract the tool from the hole. Clean any remaining chips from the finished thread.

Q: What is the difference between DIN 371 and DIN 376 standards?

A: The DIN 371 standard is used for machine taps with a reinforced shank up to a diameter of M10. The DIN 376 standard is for taps with a longer shank and is typically used for larger threads like M24 to ensure stability in deeper holes.

Q: What pilot hole do I need for the M 24 x 3.0 thread?

A: For an optimal M 24 x 3.0 thread, a pilot hole with a diameter of 21.0 mm is required. This is calculated using the formula Nominal Diameter minus Pitch (24 mm - 3.0 mm = 21.0 mm).

Q: What does "HSS-E" mean?

A: HSS-E stands for High-Speed Steel with Cobalt. The cobalt content increases the material's hot hardness, which makes the tool more resistant to high temperatures and use in tougher materials.

Q: Is this tap also suitable for use in stainless steel?

A: This tap is designed for machinable materials up to 900 N/mm², such as unalloyed and low-alloyed steels. For machining stainless steel, we recommend using specialized taps that are optimized for these materials.

Q: Why is the 35° spiral flute important for blind holes?

A: The 35° right-hand spiral ensures that chips are effectively transported upwards and out of the hole during the cutting process. This prevents chips from accumulating at the bottom of the hole, which could lead to blockages or breakage of the tap.
