The coating serves as a protective layer to prevent any damage or wear during storage and transportation. It may also indicate that the drill bit is new and has not been used before. Some manufacturers apply such coatings to maintain the quality and condition of the product until it reaches the end user.

• Diameter: 27/64 inches, which is approximately 10.72 mm, suitable for precise drilling requirements.
• Material: Often made from high-speed steel (HSS), cobalt, or carbide, depending on the specific Guhring model. The exact material impacts the bit’s durability and cutting capability.
• Coating: Guhring drill bits may feature various coatings like TiN (Titanium Nitride) or TiAlN (Titanium Aluminum Nitride) to enhance longevity and performance.
• Flute Design: Designed for efficient chip removal, reducing friction and heat buildup.

Applications

• Metalworking: Particularly suited for drilling into metals, the precise size allows for specific hole dimensions in metal fabrication.
• Woodworking: While it can be used for wood, it’s typically overkill unless precise, large-diameter holes are needed.
• Maintenance & Repair: Essential for machinery maintenance where specific hole sizes are crucial.

Pros

• Precision: Manufactured to high standards, ensuring precise diameter and hole specifications.
• Durability: High-quality materials and coatings enhance bit life, especially in demanding materials.
• Versatility: Can be used across a range of materials, though best suited for metals.

Cons

• Cost: Higher quality bits like Guhring’s can be more expensive than standard drill bits.
• Material Specificity: While versatile, optimal performance is material-dependent, requiring selection of the right bit type and coating for the job.

Industry Usage

• Manufacturing: In the manufacturing sector, precise drill bits are crucial for fabricating components with tight tolerances.
• Automotive: Used in automotive repair and manufacturing for creating or enlarging precise holes.
• Aerospace: Precision is key in aerospace applications, with specific drill bit sizes required for various tasks.
