Bosch PRO Metal HSS-G Spiral Drill Bit 13 x 101 x 151 mm

The Bosch PRO Metal HSS-G spiral drill bit is a precision-engineered tool designed for high-performance drilling in metal. Featuring a 13 mm diameter, this drill bit is manufactured from high-speed steel with a ground-flute design, ensuring exceptional cutting efficiency and consistent results. It is built to withstand the rigors of professional metalworking, offering a balance of speed and durability for demanding tasks.

Advantages

This drill bit stands out due to its precision-ground geometry, which allows for fast material removal and reduced friction during operation. The robust HSS-G construction provides excellent heat resistance, extending the tool's service life even when working with harder materials. Its design minimizes walking on the surface, ensuring accurate hole placement and clean, burr-free finishes.

Suitable for

• Drilling in alloyed and non-alloyed steel
• Working with cast iron and cast steel
• Applications in non-ferrous metals
• General metal fabrication and repair tasks

When it may not be suitable

This drill bit is not intended for drilling into masonry, concrete, or stone, as the cutting edge will dull rapidly. It is also not recommended for use with extremely hard, hardened steels or specialized high-tensile materials that require carbide-tipped tooling.

Key specifications

• Diameter: 13 mm
• Working length: 101 mm
• Total length: 151 mm
• Material: High-speed steel (HSS-G)
• Design: Ground-flute spiral

How to use

To achieve the best results, secure your workpiece firmly to prevent vibration. Start the drill at a moderate speed and apply consistent, steady pressure. It is recommended to use a cutting oil or lubricant when drilling into metal to reduce heat buildup and prolong the life of the drill bit. Ensure the drill bit is properly seated in the chuck of your power drill before starting.

What to consider before purchase

• Verify the maximum chuck capacity of your drill to ensure it accommodates a 13 mm shank.
• Check the material hardness of your workpiece to ensure compatibility with HSS-G steel.
• Consider purchasing a set if you require multiple hole sizes for your project.

Usage recommendations

Always wear appropriate eye protection and safety gear when drilling. Periodically clear metal chips from the hole to prevent clogging and overheating.
