Yato YT-28955 Hand Reamer 135 mm 7.5 mm High-Speed Steel

The Yato YT-28955 hand reamer is a precision-engineered tool designed for the accurate enlarging and finishing of pre-drilled holes. With a diameter of 7.5 mm and a total length of 135 mm, this tool provides the necessary stability and reach for professional metalworking tasks. Constructed from high-speed steel (HSS), it offers excellent hardness and heat resistance, ensuring that the tool maintains its cutting edge even during demanding operations. This reamer is an essential component for achieving precise tolerances and smooth internal surface finishes in various engineering and fabrication projects.

Advantages

The primary advantage of the Yato hand reamer lies in its robust high-speed steel construction, which significantly extends the tool's lifespan and maintains sharpness over repeated use. Its design allows for controlled material removal, which is critical for achieving exact hole dimensions that standard drill bits cannot provide. The tool is engineered to minimize vibration and chatter, resulting in a high-quality surface finish that meets professional standards. Furthermore, its compact size and manual operation capability make it highly versatile for both workshop environments and on-site adjustments where power tools may not be practical or safe.

Suitable for

• Enlarging existing holes to precise diameters
• Finishing holes in metal components
• Engineering and mechanical repair tasks
• Precision metal fabrication

This tool is not intended for use with high-speed power drills or automated CNC machinery, as it is specifically designed for manual operation. It may not be suitable for extremely hardened steels or non-metallic materials where specialized cutting geometries are required to prevent clogging or material damage.

Key specifications

• Diameter: 7.5 mm
• Total length: 135 mm
• Material: High-Speed Steel (HSS)
• Operation type: Manual

To use the Yato hand reamer, ensure the workpiece is securely clamped in a vice to prevent movement. Apply a suitable cutting fluid to the hole and the reamer to reduce friction and heat buildup. Insert the reamer into the hole and rotate it slowly and steadily in a clockwise direction while applying light, consistent downward pressure. Do not rotate the tool in reverse, as this can damage the cutting edges. Once the desired depth or diameter is achieved, carefully withdraw the tool while continuing to rotate it clockwise.

What to consider before purchase

• Verify the required hole diameter for your specific application
• Ensure the material being worked on is compatible with HSS tools
• Confirm that manual reaming is appropriate for your project requirements

For optimal results and to prolong the life of the reamer, always use a high-quality cutting oil during the reaming process. Regularly clean the flutes of the tool to remove metal shavings and inspect the cutting edges for signs of wear before each use.
