Machine taps FANAR CZP-8 HSSE for metric threads M3–M12

Machine taps FANAR CZP-8 HSSE for metric threads M3–M12 are engineered for reliable production of internal metric threads in a range from M3 to M12. Manufactured from high-speed steel with added cobalt (HSSE), these machine taps provide improved wear resistance and better performance at elevated cutting temperatures. The design suits machine tapping operations, repetitive production runs and workshop repair tasks on a variety of engineering materials including general steel and stainless steel.

Advantages

These FANAR CZP-8 HSSE taps combine the toughness of high-speed steel with cobalt alloying to increase hardness and thermal stability during cutting. The geometry of the cutting edges and flutes supports consistent chip evacuation and reduces the risk of tap breakage in through-holes and blind holes. The taps are appropriate for use in automated tapping spindles and tapping heads, providing dimensional accuracy and repeatability for metric threads from M3 through M12.

Suitable for

• Machine tapping operations in production environments
• Workshop repairs and maintenance on metal components
• Cutting metric internal threads M3, M4, M5, M6, M8, M10 and M12
• Materials such as mild steel, alloy steel and many stainless steels

Key specifications

• Thread standard: metric threads from M3 to M12
• Material: high-speed steel with cobalt for enhanced wear resistance
• Design: machine tap geometry optimized for chip evacuation and tapping accuracy
• Application: suitable for both through-holes and blind-hole tapping depending on process setup
• Use environment: intended for machine tapping spindles, tapping heads and production equipment

How to use

Select the correct tap size for the desired metric thread and ensure the workpiece has the appropriate pilot hole prepared to the recommended drill diameter for the thread size. Secure the workpiece and mount the tap in a machine tapping spindle or tapping head with proper clamping. Use cutting fluid suitable for the workpiece material to improve lubrication and cooling. Run the machine at recommended spindle speed and feed for the material and thread size, reverse the tap to break chips where necessary, and remove the tap carefully after cutting to avoid thread damage.

Usage recommendations

Use appropriate cutting fluid and monitor spindle speed and feed to extend tool life. For stainless steels and tougher alloys, reduce cutting speed and increase lubrication. Inspect finished threads for dimensional conformity and replace taps when wear or chipping affects thread quality.
