Screwdriver Bit Wiha 00639

The Wiha 00639 screwdriver bit is a professional-grade hex bit engineered for precision and durability in demanding fastening tasks. Crafted from high-quality chrome-vanadium-molybdenum (CVM) steel, this bit undergoes a rigorous through-hardening process to ensure exceptional strength and resistance to wear. Measuring 150 mm in length with a 6 mm hex tip, it provides the reach and stability required for accurate screw driving in various mechanical and assembly applications.

Advantages

This screwdriver bit stands out due to its robust construction and specialized design features. The titanium silver finish not only provides a professional appearance but also enhances corrosion resistance. A significant advantage is the integrated ball end, which allows the user to drive screws at angles of up to 25 degrees. This flexibility is essential when working in confined spaces where a straight-on approach is not possible, ensuring that the tool remains versatile and efficient for complex tasks.

Suitable for

• Precision mechanical assembly
• Automotive repair and maintenance
• Working in restricted or hard-to-reach areas
• Tasks requiring angled screw driving

This bit may not be suitable for high-torque industrial impact drivers, as it is designed primarily for manual or controlled power tool use. It is also not intended for use with fasteners that do not match the 6 mm hex drive profile.

Key specifications

• Material: Through-hardened CVM steel
• Tip type: Hex (6 mm)
• Length: 150 mm
• Weight: 35 g
• Special feature: Ball end for up to 25° working angle
• Finish: Titanium silver

To use the Wiha 00639, insert the hex end into a compatible screwdriver handle or power tool chuck. Ensure the bit is fully seated before applying torque. When utilizing the ball end feature, align the bit carefully with the screw head to maintain contact while operating at an angle. Always apply steady pressure to prevent cam-out and ensure the longevity of both the bit and the fastener.

What to consider before purchase

• Verify that your tool holder is compatible with standard 6 mm hex bits.
• Ensure the 6 mm size matches your specific fastener requirements.
• Consider the 150 mm length to ensure it provides sufficient clearance for your intended workspace.

Always inspect the bit for signs of wear or damage before use to maintain safety and precision. Store in a dry environment to prevent oxidation.
