GRAZTAI 5.0 x 245 mm Metal Drill Bit

The GRAZTAI 5.0 x 245 mm metal drill bit is a precision-engineered tool designed for demanding drilling tasks in various metal surfaces. Featuring a 5.0 mm diameter and an extended 245 mm length, this drill bit is specifically crafted to reach deep areas that standard bits cannot access. Its robust construction ensures consistent performance and durability, making it a reliable choice for both professional metalworkers and home improvement enthusiasts who require accuracy and efficiency in their drilling operations.

Advantages

This drill bit offers exceptional stability during operation, which helps in maintaining precise hole alignment even when drilling at greater depths. The high-quality material composition provides excellent resistance to heat and wear, ensuring a longer service life compared to standard bits. Its extended length allows for versatile use in deep-hole applications, reducing the need for specialized extensions and ensuring a clean finish on every project.

Suitable for

• Drilling deep holes in steel and iron
• Metal fabrication and repair projects
• Automotive maintenance and customization
• General metalworking tasks requiring extended reach

When it may not be suitable

This drill bit is not intended for use on masonry, concrete, or extremely hard tempered alloys that require specialized carbide-tipped tooling. Due to its extended length, it may be prone to bending if excessive lateral pressure is applied, so it is not recommended for high-torque impact drilling applications.

Key specifications

• Diameter: 5.0 mm
• Total length: 245 mm
• Material: High-speed steel
• Application: Metal drilling

How to use

To achieve the best results, secure your workpiece firmly in a vice or clamp to prevent movement. Start the drilling process at a low speed to create a pilot mark, then gradually increase the speed while applying steady, consistent pressure. It is essential to use a suitable cutting oil or lubricant to reduce friction and heat buildup, which will protect the drill bit from overheating and extend its sharpness. Always ensure the drill bit is perfectly perpendicular to the surface to avoid snapping the bit during deep-hole drilling.

What to consider before purchase

• Verify the chuck capacity of your drill to ensure it accommodates a 5.0 mm shank
• Check the depth requirements of your project to confirm the 245 mm length is sufficient
• Ensure you have appropriate cooling lubricant available for metal drilling

Usage recommendations

Always wear appropriate eye protection and safety gear when operating power tools. Periodically retract the drill bit during deep drilling to clear metal shavings from the hole, which prevents clogging and overheating.
