Insert Bit c.k tools T4545 1, Chrome Vanadium, 6.3 mm, 2 pcs

Replaceable insert bit c.k tools T4545 1 is a pair of 6.3 mm screwdriver bits manufactured from chrome vanadium steel. Supplied as two pieces, these bits are intended for use with compatible bit holders and screwdrivers for general fastening and repair tasks. The chrome vanadium construction provides corrosion resistance and a durable cutting edge, making the set a practical spare for workshops, service vehicles and field use.

Advantages

These insert bits offer reliable mechanical strength and wear resistance due to the chrome vanadium material. The 6.3 mm diameter ensures compatibility with standard 1/4" bit holders and many handheld drivers, while the compact pack of two provides immediate replacement options. Their corrosion-resistant finish helps maintain performance in mixed indoor and outdoor conditions.

Suitable for

• General fastening and assembly tasks
• Maintenance and repair work in workshops and service vehicles
• On-site field repairs where quick bit replacement is required
• Use with standard 6.3 mm (1/4") bit holders and drivers

Key specifications

• Material: chrome vanadium steel
• Diameter: 6.3 mm (standard 1/4" size)
• Quantity: 2 pieces per pack
• Finish: corrosion-resistant surface treatment
• Type: replaceable insert bit for screwdriver/bit holder use

How to use

Insert the bit into a compatible 6.3 mm (1/4") bit holder or screwdriver chuck until it clicks or seats firmly. Use appropriate torque settings on powered drivers to avoid overloading the bit; for manual use, apply steady pressure and avoid excessive side loads that can deform the tip. Replace a worn or damaged bit with the spare included in the pack to maintain fastening accuracy and reduce the risk of fastener damage.

Usage recommendations

Store the bits in a dry place to preserve the corrosion-resistant finish. Match the bit type and size to the fastener head to ensure proper engagement and minimize wear. For high-torque powered applications, use impact-rated bits when required; these chrome vanadium bits are suited to general-purpose tasks but should be inspected regularly for signs of wear.
