Threading tap set YATO YT-44849, HSS, 5 pcs

YATO YT-44849 is a 5-piece threading tap set made from high-speed steel (HSS) designed for cutting internal threads in metals and other machinable materials. The set includes a selection of taps suitable for standard workshop and maintenance tasks, offering wear resistance and dimensional stability for conventional tapping operations. Intended for use in both manual and machine tapping, this HSS tap set is sized and surfaced to deliver consistent thread profiles when used according to material and size recommendations.

Advantages

The HSS construction provides improved hardness and resistance to wear compared with carbon steel taps, extending service life under normal workshop conditions. Precision-ground flutes and cutting edges promote accurate thread form and reliable engagement with dies and bolts. The 5-piece configuration supplies a range of commonly used tap sizes, reducing the need to change tools frequently and enabling efficient workflow in maintenance and fabrication tasks.

Suitable for

• Cutting internal threads in steel, aluminium and other machinable metals
• Workshop repairs and maintenance operations
• Manual tapping with tap wrenches and machine tapping in drill presses or milling machines
• Prototyping and small-batch production where standard thread sizes are required

Key specifications

• Material: high-speed steel (HSS)
• Set size: 5 pieces (assorted common tap sizes)
• Application: internal thread cutting (tapping)
• Suitable for manual and machine tapping
• Finish: ground cutting edges and flutes for chip evacuation

How to use

Select the correct tap size for the required thread and prepare the hole with the recommended drill size for the thread pitch. Secure the workpiece and align the tap square to the hole axis. Apply appropriate cutting fluid for the base material to reduce friction and improve chip removal. For manual tapping, use a tap wrench and turn steadily, reversing periodically to break chips. For machine tapping, set the correct spindle speed and feed, and ensure rigid clamping to prevent wobble or breakage. After completing the thread, back the tap out while cleaning chips from the flutes.

Usage recommendations

Use cutting fluid for steel and harder alloys, moderate speeds for machine tapping, and avoid excessive side loads. Replace taps that show wear or chipped cutting edges to maintain thread quality and reduce the risk of tap breakage.
