Screwdriver bit holder Makita B-57750, length 150 mm, 1 pc

Makita B-57750 is a 150 mm screwdriver bit holder supplied as a single piece. It accepts standard 1/4" hex screwdriver bits and increases reach for working in recessed or hard-to-access fasteners. The design provides a secure magnetic retention for bits and is intended to be used with manual and powered drivers to facilitate general assembly, maintenance and repair tasks where extra length and reliable bit holding are required.

Advantages

This 150 mm bit holder extends the working reach without compromising control, allowing access to fasteners located deep inside assemblies or behind obstacles. Its magnetic tip helps keep bits firmly in place during insertion and removal, reducing the chance of dropped bits. Being a single-piece accessory, it is lightweight and easy to store in toolboxes or on bit holders.

Suitable for

• Assembly work where screws are recessed or hard to reach
• Maintenance and repair tasks on appliances, furniture, and equipment
• Use with cordless and corded drivers for extended reach

When it may not be suitable

This bit holder is a straight 150 mm extension and may not be suitable where flexible or angled access is required. It is designed for standard 1/4" hex bits and will not interface with proprietary or non-standard bit shanks. For heavy-duty torque applications, a shorter or specially rated holder may be preferable to avoid bending or stress.

Key specifications

• Length: 150 mm
• Bit interface: 1/4" hex
• Retention: magnetic tip
• Quantity: 1 piece
• Compatible with manual and powered screwdriver/drill drivers

How to use

Insert a compatible 1/4" hex screwdriver bit into the magnetic tip until it seats securely. Fit the opposite end of the holder into the chuck or bit holder of your driver. When driving screws, maintain steady, axial pressure to keep the bit engaged and avoid side loads that may cause slippage or bending. Remove the bit by pulling it straight out from the magnetic tip when finished.

What to consider before purchase

• Ensure your screwdriver bits are 1/4" hex compatible
• Consider if a fixed 150 mm length meets the access needs of your tasks
• Verify compatibility with your driver’s chuck or quick-change adapter

Usage recommendations

Use the Makita 150 mm bit holder for tasks with recessed screws and moderate torque. Avoid excessive lateral force and high-torque impacts; for impact-driving or very high torque, use holders rated for those conditions or consider shortening the extension to minimize bending stress.
