Fanar D2-511101-0245 M24x1.5 DIN-374C R40 HSSE 800 Machine Tap

The Fanar M24x1.5 machine tap is a high-precision industrial tool engineered for creating accurate internal threads in through-holes. Manufactured from HSSE 800 cobalt-alloyed high-speed steel, this tap offers exceptional wear resistance and thermal stability, ensuring consistent performance during demanding metalworking operations. Its design adheres to the DIN-374C standard, featuring an R40 spiral point geometry that effectively pushes chips forward, preventing clogging and ensuring a smooth threading process.

Advantages

The primary advantage of this machine tap lies in its high-quality cobalt-alloyed steel composition, which significantly extends tool life even when machining tougher materials. The R40 spiral point geometry is specifically optimized for through-hole applications, facilitating efficient chip evacuation and reducing the risk of thread damage. By maintaining strict DIN-374C tolerances, this tool provides reliable thread accuracy and repeatability, which is essential for industrial manufacturing environments where precision is paramount.

Suitable for

• Threading through-holes in various steel grades
• Industrial metalworking and machining centers
• Production environments requiring high thread precision
• Applications where efficient chip evacuation is necessary

When it may not be suitable

This machine tap is not designed for blind-hole threading, as the spiral point geometry pushes chips forward rather than pulling them out of the hole. It may also show reduced performance when used on extremely hardened materials or exotic alloys that exceed the recommended hardness range for standard HSSE 800 tools.

Key specifications

• Thread size: M24x1.5
• Material: HSSE 800 cobalt-alloyed high-speed steel
• Standard: DIN-374C
• Geometry: R40 spiral point
• Tolerance class: 6H

How to use

Before beginning the threading process, ensure the workpiece is securely clamped to prevent vibration. Select the appropriate drill size for the M24x1.5 thread and ensure the hole is clean. Apply a high-quality cutting oil or coolant to the tap and the hole to reduce friction and heat buildup. Align the tap perfectly with the axis of the hole to avoid misalignment or thread damage. Use a rigid machine setup and maintain a consistent feed rate to achieve the best results.

What to consider before purchase

• Verify that the application involves through-holes rather than blind holes
• Ensure the machine spindle is compatible with the tap shank size
• Check that the material hardness is suitable for HSSE 800 steel
• Confirm the required thread tolerance class for your specific assembly

Usage recommendations: Always use appropriate cutting fluids to maximize the lifespan of the tool and ensure a superior surface finish on the threads. Regularly inspect the tap for signs of wear or chipping to maintain consistent production quality.
