Threading tap YATO YT-44845 HSS, length 51 mm, shank Ø 6.3 mm, 1 pc

YATO YT-44845 is a single-piece threading tap manufactured from High-Speed Steel (HSS) with a total length of 51 mm and a shank diameter of 6.3 mm. Designed for cutting internal threads in a variety of metal workpieces, this tap provides a compact tool profile suitable for confined spaces and fits standard 6.3 mm tool holders or collets. It is supplied as a single unit and is intended for use in manual tapping or machine tapping operations where HSS wear resistance and cutting precision are required.

Advantages

The HSS construction delivers a balance of hardness and toughness that supports repeated use on mild and medium-hard metals. The short overall length reduces deflection and improves control during manual tapping and in short-reach machine applications. A 6.3 mm shank enables compatibility with common tool holders and quick-change systems. Supplied as one piece, the tap is ready for immediate use without additional assembly.

Suitable for

• Cutting internal metric threads in steel, stainless steel, aluminum and non-ferrous alloys
• Manual tapping with tap wrenches and T-handles
• Machine tapping in drill presses, milling machines or tapping heads with appropriate holders
• Repairing or finishing existing threaded holes in assemblies and prototypes

Key specifications

• Material: High-Speed Steel (HSS)
• Total length: 51 mm
• Shank diameter: 6.3 mm
• Package quantity: 1 piece
• Tool type: single-piece (solid) threading tap for internal threads

How to use

Select the correct drill size for the target thread and secure the workpiece to prevent movement. Clamp the tap by its shank in a suitable holder or tap wrench. For machine tapping, ensure the holder and spindle are aligned and the machine speed is appropriate for the material. Apply cutting fluid suitable for the workpiece material, advance the tap with steady, even pressure and use intermittent backing-off to clear chips. After cutting, retract the tap, clean the threads and remove any remaining chips or cutting fluid from the hole.

Usage recommendations

Use appropriate cutting oil for ferrous materials and moderate speeds to extend tool life. Avoid excessive side loading and ensure proper alignment to prevent tap breakage. For hardened materials or high-volume production, consider coatings or taps made from more wear-resistant grades.
