Makita D-09737 HSS-G Metal Drill Bit 5.5 x 93 mm

The Makita D-09737 HSS-G metal drill bit is a precision-engineered tool designed for high-performance drilling in various metal materials. With a diameter of 5.5 mm and a total length of 93 mm, this drill bit is manufactured from high-speed steel, ensuring excellent heat resistance and durability during intensive use. The bit features a specialized chisel edge design that promotes accurate centering and reduces walking on the workpiece surface, allowing for clean and professional results in every application.

Advantages

This drill bit offers superior cutting efficiency due to its high-quality HSS-G construction, which maintains sharpness over extended periods of operation. The cylindrical shank design ensures compatibility with a wide range of standard drill chucks, providing a secure grip and stable rotation. Its robust build quality minimizes the risk of breakage, making it a reliable choice for both demanding professional metalworking environments and precise DIY tasks.

Suitable for

• Drilling holes in steel and iron
• General metal fabrication tasks
• Precision drilling for mechanical assembly
• DIY metal repair and maintenance projects

When it may not be suitable

This drill bit is specifically optimized for metal applications and may experience premature wear if used on abrasive materials like masonry, concrete, or hardened ceramics. It is not intended for use with hammer drill functions, as the impact force can damage the cutting edge.

Key specifications

• Diameter: 5.5 mm
• Total length: 93 mm
• Material: High-Speed Steel (HSS-G)
• Shank type: Cylindrical
• Tip geometry: Chisel edge

How to use

To achieve the best results, secure your workpiece firmly in a vice or clamp to prevent movement during the drilling process. Insert the drill bit into the chuck of your power drill and tighten it securely. It is recommended to use a center punch to mark the exact location of the hole before starting, which helps prevent the bit from sliding. Apply steady, moderate pressure while drilling and maintain a consistent speed, using cutting oil if necessary to reduce friction and heat buildup, which will extend the life of the bit.

What to consider before purchase

• Verify the chuck capacity of your drill to ensure it accommodates the cylindrical shank.
• Ensure the 5.5 mm diameter meets the specific requirements of your project or fastener size.
• Consider purchasing multiple bits if working with thick or hardened metal plates to account for potential wear.

Usage recommendations

Always wear appropriate eye protection when drilling metal to guard against flying chips. Periodically clear the drill hole of metal shavings to prevent clogging and overheating of the bit.
