Advantages
The primary benefit of this double-end drill bit is its enhanced durability and cost-effectiveness. By offering two cutting ends in a single tool, it reduces the frequency of replacements and minimizes downtime during projects.

Automotive repair and bodywork
General metal fabrication and assembly
Maintenance tasks in professional workshops
When it may not be suitable
This drill bit is not intended for drilling into masonry, concrete, or extremely hard hardened steel alloys, as these materials may cause premature dulling or breakage. It is also not recommended for use in high-impact hammer drill modes.
Key specifications
Diameter: 4.2 mm
Total length: 55 mm
Design: Double-ended
Material compatibility: Metal and general alloys
How to use
To use the GRAZTAI drill bit, securely insert one end into the chuck of your power drill or drill press, ensuring it is tightened properly to prevent slippage. Mark the center of the hole to be drilled to ensure accuracy. Apply steady, moderate pressure while maintaining a consistent speed suitable for the material being drilled. If the cutting edge becomes dull, simply remove the bit, reverse it, and insert the unused end into the chuck to continue working immediately.
What to consider before purchase
Verify that the 4.2 mm diameter matches your specific fastener or hole requirements.
Ensure your drill chuck is compatible with standard cylindrical shank bits.
Consider purchasing multiple units if you are working on large-scale projects to maintain continuous workflow.
Usage recommendations
Always wear appropriate eye protection when drilling metal. Use a cutting fluid or lubricant to reduce friction and heat, which will significantly prolong the lifespan of the drill bit and improve the quality of the hole finish.
