## Summary description

This set includes 3 extended HSS metal drill bits by GRAPHITE, manufactured according to the DIN 340 standard. With a diameter of 1 mm, these high-speed steel bits are designed for precise drilling in metal materials. The extended length provides better reach for deep holes, making them a reliable choice for professional and workshop applications requiring durability and accuracy.

## Long description

The GRAPHITE HSS metal drill bit set consists of three high-quality, extended drill bits designed for precision drilling in metal. Manufactured in accordance with the DIN 340 standard, these bits offer enhanced reach, allowing for deeper hole drilling than standard-length bits. Constructed from high-speed steel, they provide the necessary hardness and heat resistance required for consistent performance in demanding workshop environments.
Advantages
The primary advantage of these drill bits is their extended length, which facilitates access to hard-to-reach areas and enables the creation of deep holes with high accuracy. The high-speed steel composition ensures that the bits maintain their cutting edge even under significant thermal load, contributing to a longer service life. Their adherence to the DIN 340 standard guarantees compatibility and reliability for professional metalworking tasks.
Suitable for
Drilling deep holes in steel and non-ferrous metals
Precision metalworking in workshops
Professional assembly and repair tasks
Applications requiring extended reach for drilling
When it may not be suitable
These drill bits are specifically designed for metal applications and may not be optimal for drilling in masonry, concrete, or soft materials like wood where specialized geometry is required for chip removal. Due to their small 1 mm diameter, they are susceptible to breakage if subjected to excessive lateral pressure or improper feed rates.
Key specifications
Material: High-speed steel (HSS)
Standard: DIN 340
Diameter: 1 mm
Quantity: 3 pieces
Type: Extended length
How to use
To use these drill bits, ensure the workpiece is securely clamped to prevent vibration or movement during the drilling process. Insert the bit into a compatible drill chuck, ensuring it is centered and tightened firmly. Start the drilling process at a low speed to establish the hole position, then gradually increase the speed while applying steady, controlled pressure. It is recommended to use a suitable cutting oil to reduce friction and heat, which helps preserve the sharpness of the bit and improves the quality of the hole.
What to consider before purchase
Verify that your drill chuck is compatible with a 1 mm diameter shank
Ensure the extended length is appropriate for your specific drilling depth requirements
Consider the hardness of the material being drilled to ensure HSS is the correct choice
Usage recommendations
Always wear appropriate eye protection when drilling metal. Regularly clear metal chips from the hole during deep drilling to prevent the bit from binding or breaking.
