Bosch HSS-G Metal Drill Bit 5.5 mm

The Bosch HSS-G metal drill bit with a 5.5 mm diameter is a precision-engineered tool designed for high-performance drilling in various materials. Crafted from high-speed steel and ground from solid metal, this drill bit ensures excellent drilling rates and long-lasting durability. Its robust construction makes it a reliable choice for both professional metalworking and demanding DIY projects where accuracy and efficiency are paramount.

Advantages

This drill bit features a precision-ground design that allows for clean and accurate hole creation. The high-speed steel material provides superior heat resistance and structural integrity, ensuring the bit maintains its sharpness even during intensive use. Its right-hand cutting geometry is optimized for smooth material removal, reducing the risk of binding and improving overall productivity in metalworking tasks.

Suitable for

• Drilling in alloyed and non-alloyed steel
• Working with cast iron and cast steel
• Processing non-ferrous metals
• Creating holes in hard plastics

When it may not be suitable

This drill bit is not intended for use on masonry, concrete, or extremely hardened materials that require specialized carbide-tipped bits. Using it on materials outside its recommended scope may lead to premature wear or damage to the cutting edge.

Key specifications

• Diameter: 5.5 mm
• Total length: 93 mm
• Working length: 57 mm
• Material: High-speed steel (HSS-G)
• Cutting direction: Right-hand

How to use

To achieve the best results, secure your workpiece firmly to prevent vibration or movement during the drilling process. Start by using a center punch to mark the exact location of the hole, which helps guide the drill bit and prevents it from wandering. Apply steady, moderate pressure and maintain a consistent speed appropriate for the material being drilled. It is important to keep the drill bit aligned perpendicular to the surface to ensure a straight and accurate hole.

What to consider before purchase

• Verify the chuck capacity of your drill to ensure it accommodates a 5.5 mm shank.
• Ensure the drill bit material is compatible with the hardness of your target surface.
• Consider purchasing a cutting fluid to extend the life of the bit.

Usage recommendations

For optimal performance and to prevent overheating, it is highly recommended to use a suitable coolant or cutting oil during the drilling process, especially when working with metals.
