Makita D-06339 Metal Drill Bit HSS-G 4.0 x 75mm - Pack of 10

According to the product description, it’s suitable for drilling in wood, metal, plastic, and other soft materials. Its HSS-G construction is optimized for durability and smooth cutting across these materials.

Key specs: 4 mm diameter, 75 mm flute/overall length, straight shank for secure chuck fitting, HSS-G material with a rust-resistant coating, designed for quick drilling action, and sold as a pack of 10.

Yes. The straight shank design is compatible with most standard drill chucks, making it easy to use in common hand drills and drill presses.

Steps: (1) Secure the workpiece with a clamp. (2) Open the drill chuck and insert the 4 mm straight shank. (3) Tighten the chuck firmly. (4) Use a suitable drill speed for the material (start slower to establish a pilot hole). (5) Apply light pressure and back off frequently to clear chips. (6) For metal, consider using a cutting fluid or lubricant to reduce heat and extend bit life.

Wear safety glasses to protect your eyes, use gloves if appropriate, clamp the workpiece, ensure the drill is secured, avoid excessive force which can cause bit breakage, and monitor for heat buildup. Use lubrication when drilling metal to minimize heat and wear.

Keep the bit clean and dry after use, wipe away debris, store it in a dry place to prevent rust, and avoid overheating by using proper speeds and lubrication when drilling metal.

It's well-suited for creating small pilot holes and thin metal workpieces, as well as general-purpose drilling in lightweight metals, plastics, and soft woods where a precise 4 mm hole is needed.

Differences typically include overall length, flute design, coating quality, and pack size. The D-06339 emphasizes a 4.0 mm diameter, 75 mm length, straight shank, rust-resistant coating, and a pack of 10. When comparing with other Makita 4 mm bits, check the length, shank style, and coating in the product specs.

HSS-G stands for high-speed steel grade G. It offers good heat resistance and durability for general-purpose drilling, which helps maintain sharpness and extend life during metal and plastic drilling.

The Makita D-06339 is listed as a pack of 10 drill bits, which provides multiple bits for longer projects and reduces the need for frequent replacements, offering better value for ongoing use.

While the product description indicates versatility for wood, metal, and plastic, performance and hole quality can vary by material. For metal, use light lubrication and appropriate speeds; for wood or plastic, a slower feed and appropriate speed will typically yield clean holes.
