Yato YT-44841 M4 HSS Drill-Tap with 1/4" HEX Shank

The Yato YT-44841 is a professional-grade M4 drill-tap manufactured from high-speed steel (HSS), engineered to streamline metalworking tasks by combining drilling and threading into one efficient process. Equipped with a standard 1/4" HEX shank, this tool offers seamless compatibility with most power drills, impact drivers, and bit holders, ensuring quick tool changes and reliable performance during demanding applications.

Advantages

This drill-tap significantly increases productivity by eliminating the need to switch between separate drill bits and taps, allowing for continuous operation in a single pass. The high-speed steel construction provides excellent heat resistance and durability, maintaining a sharp cutting edge even during repetitive use in various metal materials. Its precise geometry ensures accurate thread formation, reducing the risk of material damage and ensuring a secure fit for M4 fasteners.

Suitable for

• Creating M4 threads in metal sheets and profiles
• Fast assembly of threaded connections in DIY and professional workshops
• Repair and maintenance tasks requiring quick thread restoration
• Use with cordless drills and impact drivers featuring 1/4" hex chucks

When it may not be suitable

This tool is not intended for use on hardened steel or extremely thick metal plates where the length of the tap may be insufficient. It is also not recommended for use with manual hand tools that lack the necessary rotational speed and stability for effective drilling and tapping.

Key specifications

• Thread size: M4
• Material: High-speed steel (HSS)
• Shank type: 1/4" HEX
• Total length: 39 mm

How to use

To use the Yato drill-tap, secure it firmly into the 1/4" hex holder of your power tool. Ensure the workpiece is properly clamped to prevent movement. Align the tool perpendicular to the surface and apply steady, moderate pressure while maintaining a low to medium rotational speed. Allow the drill point to penetrate the material completely before the threading section engages. Once the thread is formed, reverse the rotation of the tool to back it out of the hole carefully.

What to consider before purchase

• Verify that your power tool supports 1/4" hex shank accessories
• Ensure the material thickness is compatible with the tool's reach
• Check that the required thread size is exactly M4

Usage recommendations

Always use a suitable cutting oil or lubricant during the drilling and tapping process to reduce friction, prevent overheating, and extend the lifespan of the tool. Wear appropriate eye protection during operation.
