## Summary description

Set of two professional GRAPHITE HSS metal drill bits, model 54T925. These extended drill bits comply with the DIN 340 standard, ensuring precision and durability when drilling deep holes in steel and other metals. Designed for high-performance industrial and workshop use, they provide excellent heat resistance and efficient chip removal for clean, accurate results in demanding drilling applications.

## Long description

The GRAPHITE HSS metal drill bit is a professional-grade tool designed for precision drilling in metal surfaces. Measuring 2.5 mm in diameter and featuring an extended length according to the DIN 340 standard, this drill bit is engineered to reach deeper areas that standard bits cannot access. Constructed from high-speed steel, it offers the durability and heat resistance required for consistent performance in industrial and workshop environments.
Advantages
The primary benefit of this drill bit is its extended geometry, which allows for deep-hole drilling without compromising structural integrity. The high-speed steel composition ensures that the cutting edge remains sharp even during prolonged use, while the design facilitates efficient chip removal to prevent overheating and clogging. This results in cleaner, more accurate holes and increased productivity during metalworking tasks.
Suitable for
Drilling deep holes in steel and non-ferrous metals
Industrial metalworking and fabrication
Precision workshop applications
Tasks requiring extended reach for drilling through thick materials
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 soft wood, where different tip geometries are required. Additionally, due to its thin 2.5 mm diameter, it is susceptible to bending or breaking if subjected to excessive lateral pressure or used with unstable power tools.
Key specifications
Diameter: 2.5 mm
Standard: DIN 340
Material: High-speed steel (HSS)
Type: Extended length
Quantity: 2 pieces
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 of the hole to be drilled using a center punch to prevent the bit from wandering. Apply steady, moderate pressure while maintaining a consistent speed suitable for the material being drilled. It is recommended to use a cutting oil or lubricant to reduce friction and heat, which will significantly extend the lifespan of the drill bit.
What to consider before purchase
Verify that your drill chuck is compatible with a 2.5 mm shank diameter.
Ensure the extended length is appropriate for the depth of your specific project.
Consider the hardness of the material to ensure HSS is the correct material choice.
Usage recommendations
Always wear appropriate eye protection when drilling metal. Periodically clear metal chips from the hole during deep drilling to prevent the bit from binding or breaking.
