Abraboro HSS Metal Drill Bit, Cylindrical Shank, 12.5 mm, 5-Piece Set

The Abraboro HSS metal drill bit set is a professional-grade solution designed for precision drilling in various metal materials. Each bit features a 12.5 mm diameter and a standard cylindrical shank, ensuring compatibility with a wide range of drill chucks. Manufactured from high-speed steel, these bits are engineered to maintain their cutting edge integrity even when subjected to the heat and friction associated with drilling through steel and metal alloys.

Advantages

These drill bits offer exceptional durability and heat resistance, which are critical factors for consistent performance in metalworking environments. The high-speed steel construction allows for efficient chip removal and reduced wear over extended periods of use. By providing a set of five, the product ensures that users have reliable replacements on hand, maintaining productivity in both industrial settings and professional workshops.

Suitable for

• Drilling into structural steel and mild steel
• Working with various metal alloys
• Industrial manufacturing and maintenance tasks
• Professional workshop metalworking projects

When it may not be suitable

These drill bits are specifically optimized for metal applications and may experience premature wear if used extensively on abrasive materials like masonry, concrete, or hardened stone. They are also not intended for use on soft materials where specialized geometry is required to prevent clogging.

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 12.5 mm
• Shank type: Cylindrical
• Quantity: 5 pieces

How to use

To achieve the best results, ensure the drill bit is securely fastened in the chuck of your power tool. It is recommended to use a center punch to mark the drilling location to prevent the bit from wandering. Apply steady, moderate pressure while drilling and maintain a consistent speed appropriate for the material thickness. Using a suitable cutting oil can significantly improve the finish of the hole and extend the lifespan of the drill bit by reducing friction and heat buildup.

What to consider before purchase

• Verify that your drill chuck supports a 12.5 mm cylindrical shank diameter.
• Ensure your power tool has sufficient torque for drilling 12.5 mm holes in metal.
• Consider the hardness of the specific metal alloy you intend to drill.

Usage recommendations

Always wear appropriate eye protection and safety gear when operating power tools. Periodically inspect the drill bits for signs of dulling or damage to ensure continued precision and safety during operation.
