Bosch HSS-G Metal Drill Bit 10.5 x 133 mm

The Bosch HSS-G metal drill bit, with a diameter of 10.5 mm and a total length of 133 mm, is a high-performance tool engineered for precision drilling in various metal materials. Crafted from high-speed steel and precision-ground, this drill bit offers excellent durability and efficient material removal, making it a reliable choice for both professional metalworking tasks and demanding DIY projects.

Advantages

The primary advantage of this drill bit is its precision-ground HSS-G construction, which allows for faster drilling speeds and reduced friction during operation. This design ensures that the bit maintains its sharpness over extended periods, providing clean and accurate holes in steel, cast iron, and other metal alloys. Its robust build quality minimizes the risk of breakage and ensures consistent performance even under continuous use.

Suitable for

• Drilling holes in steel and steel alloys
• Working with cast iron
• General metalworking and fabrication tasks
• DIY home improvement projects requiring metal drilling

When it may not be suitable

This drill bit is specifically optimized for metal applications and may not be the most efficient choice for drilling into masonry, concrete, or extremely hard materials like hardened steel or ceramics. Using it on materials outside its intended scope may lead to premature dulling or damage to the cutting edges.

Key specifications

• Diameter: 10.5 mm
• Total length: 133 mm
• Material: High-speed steel (HSS-G)
• Application: Metal drilling

How to use

To achieve the best results, ensure the drill bit is securely fastened in the chuck of your power drill or drill press. Mark the center point of the hole to be drilled and use a center punch to create a small indentation, which helps prevent the bit from wandering. Apply steady, moderate pressure while maintaining a consistent drilling speed, and use a suitable cutting oil to lubricate the bit and dissipate heat, which will significantly extend the life of the tool.

What to consider before purchase

• Ensure the 10.5 mm diameter matches your specific project requirements
• Verify that your drill chuck is compatible with the shank size
• Consider the material thickness to ensure the 133 mm length is sufficient

Usage recommendations

Always wear appropriate eye protection when drilling metal to prevent injury from flying chips. Periodically check the bit for signs of wear and keep it clean to maintain optimal drilling performance.
