Makita D-09715 HSS-G Metal Drill Bit 4.5 x 80 mm

The Makita D-09715 HSS-G metal drill bit is a precision-engineered tool designed for high-performance drilling in various metal materials. With a diameter of 4.5 mm and a total length of 80 mm, this drill bit is crafted from high-speed steel, ensuring excellent heat resistance and durability during intensive use. Its robust construction allows for consistent hole quality and efficient material removal, making it a reliable choice for both professional metalworkers and home improvement enthusiasts.

Advantages

This drill bit features a specialized chisel edge design that facilitates quick centering and reduces walking on the workpiece surface, leading to more accurate hole placement. The high-speed steel composition provides superior hardness and wear resistance, extending the tool's lifespan even when working with tough metals. Its cylindrical shank design ensures compatibility with a wide range of standard power drills and drill presses, offering versatility and ease of use in various workshop environments.

Suitable for

• Drilling holes in steel and iron
• General metal fabrication tasks
• Precision DIY metalworking projects
• Maintenance and repair work

This drill bit may not be suitable for drilling through hardened steel, stainless steel alloys, or masonry, as these materials require specialized cobalt or carbide-tipped bits to prevent premature wear or breakage. It is also not intended for use in impact drivers or hammer drills, which can damage the bit's geometry.

Key specifications

• Material: High-Speed Steel (HSS-G)
• Diameter: 4.5 mm
• Total length: 80 mm
• Shank type: Cylindrical
• Application: Metal drilling

To use the Makita HSS-G drill bit, ensure that your power drill is set to the appropriate speed for the material being drilled. Secure the workpiece firmly with a clamp or vice to prevent movement. Align the drill bit tip with the desired center point and apply steady, moderate pressure while maintaining a perpendicular angle to the surface. Allow the bit to cut through the material without forcing it, and periodically clear metal shavings to prevent overheating.

What to consider before purchase

• Verify the required hole diameter for your specific project
• Ensure your drill chuck is compatible with a cylindrical shank
• Check if the material hardness is appropriate for standard HSS-G bits

For optimal performance and longevity, use a suitable cutting oil or lubricant when drilling metal to reduce friction and heat buildup. Always wear appropriate eye protection during operation.
