Makita D-09684 HSS-G Metal Drill Bit 3.0 x 61 mm

The Makita D-09684 HSS-G metal drill bit is a precision-engineered tool designed for high-performance drilling in various metal surfaces. With a diameter of 3.0 mm and a total length of 61 mm, this drill bit is manufactured from high-speed steel, ensuring excellent durability and resistance to heat during intensive use. Its ground flute design facilitates efficient chip removal, which helps maintain a consistent drilling speed and prevents overheating, resulting in clean and accurate holes every time.

Advantages

This drill bit offers exceptional stability and accuracy, making it a reliable choice for demanding metalworking tasks. The HSS-G construction provides superior hardness and wear resistance compared to standard bits, allowing for a longer service life even when working with tough materials. Its geometry is optimized for quick penetration, reducing the physical effort required during operation and minimizing the risk of bit wandering on the workpiece surface.

Suitable for

• Drilling holes in mild steel and carbon steel
• Working with non-ferrous metals such as aluminum and copper
• Precision metal fabrication and repair projects
• General DIY metalworking tasks

When it may not be suitable

This drill bit is not intended for drilling into hardened steel, stainless steel, or masonry materials, as these require specialized cobalt or carbide-tipped bits. Using this tool on materials harder than its design specifications may lead to rapid dulling or breakage of the cutting edge.

Key specifications

• Diameter: 3.0 mm
• Total length: 61 mm
• Material: High-speed steel (HSS-G)
• Application: Metal drilling

How to use

To achieve the best results, secure your workpiece firmly in a vice or clamp to prevent movement. Mark the center point of the hole clearly before starting. Begin drilling at a low to moderate speed, applying steady and consistent pressure. It is recommended to use a cutting oil or lubricant to reduce friction and heat, which will significantly extend the life of the drill bit and improve the quality of the finish.

What to consider before purchase

• Ensure the drill bit diameter matches your specific project requirements
• Verify that your power drill chuck is compatible with a 3.0 mm shank
• Check if your material hardness is suitable for standard HSS-G bits

Usage recommendations

Always wear appropriate eye protection when drilling metal to prevent injury from flying chips. Periodically clear the drill bit of debris and allow it to cool down if it becomes excessively hot during prolonged use.
