## Long description

The Bosch HSS PointTeQ twist drill bit is a high-performance tool engineered for efficient and precise drilling in metal. Featuring a 7.5 mm diameter, these drill bits utilize advanced PointTeQ tip technology to ensure rapid drilling speeds and exceptional durability. This 10-piece set provides a reliable solution for both professional metalworking projects and demanding DIY tasks, offering consistent performance and high resistance to wear.
Advantages
The primary advantage of the PointTeQ design is its ability to start drilling immediately without the need for center punching, which significantly increases the drilling rate while reducing heat generation and overall tool wear. The highly elastic body of the drill bit minimizes the risk of breakage during operation, while the black-oxide coated flute facilitates rapid chip removal, ensuring a cleaner and more efficient drilling process. These bits are built to maintain their sharpness over extended periods, providing long-lasting reliability for various metal applications.
Suitable for
Drilling in alloyed and non-alloyed steel
Metalworking projects requiring high precision
Professional construction and maintenance tasks
DIY metal drilling applications
When it may not be suitable
These drill bits are specifically optimized for metalworking and may not provide optimal results when used on masonry, concrete, or extremely hard materials like hardened steel or ceramics. Using them on materials outside their intended scope may lead to premature dulling of the tip or damage to the drill bit.

How to use
To use the Bosch HSS PointTeQ drill bit, ensure it is securely fastened into the chuck of your drill driver or drill stand. Align the tip precisely with the intended drilling point. Apply steady, moderate pressure while maintaining a consistent speed suitable for the metal being drilled. The self-centering PointTeQ tip eliminates the need for pre-punching, allowing for a smooth start. Always ensure the drill is set to the correct rotation speed to prevent overheating and to maximize the lifespan of the bit.
What to consider before purchase
Verify that your drill chuck is compatible with the 7.5 mm cylindrical shank.
Ensure the drill bit diameter matches your specific project requirements.
Confirm that your power tool is suitable for metal drilling applications.
Usage recommendations: For best results, use a cutting oil or lubricant when drilling into metal to reduce friction, dissipate heat, and extend the life of the drill bit. Always wear appropriate eye protection during operation.
