Screwdriver Bit Set Makita E-03327 2 pcs T10 1/4 50 mm

The Makita E-03327 screwdriver bit set contains two 50 mm bits designed for secure fastener engagement and reliable performance in maintenance, assembly, and repair tasks. The set includes a T10 Torx bit and a 1/4" security hex bit, both sized to fit standard 1/4" bit holders and quick-change chucks. Each bit is produced to provide precise fit, reduce cam-out, and withstand repeated use in hand and powered drivers.

Advantages

Both 50 mm bits are manufactured to offer consistent tip geometry for accurate torque transfer and minimal wear. The Torx and security hex profiles improve engagement with corresponding fasteners, lowering the risk of stripping. Compatibility with common 1/4" holders and the compact length make these bits practical for confined spaces and general-purpose toolkits.

Suitable for

• Precision assembly and electronics where T10 Torx fasteners are used
• Maintenance and repair tasks requiring security hex access
• Work with cordless and corded screwdrivers that accept 1/4" bits
• Accessing fasteners in tight or recessed locations

Key specifications

• Quantity: 2 pieces
• Bit types: T10 Torx and security hex (1/4")
• Shank size: 1/4" compatible
• Length: 50 mm each
• Intended use: manual and powered screwdrivers, quick-change chucks

How to use

Select the Torx or security hex bit according to the fastener head and insert the 1/4" shank into a compatible bit holder or chuck until it seats securely. Apply steady, aligned pressure while operating the driver to ensure correct engagement with the fastener tip. For powered drivers, start at low speed to confirm fit, then increase speed and torque as needed. After use, inspect the bit tip for wear and store in a bit holder to maintain tip geometry.

Usage recommendations

Use the T10 Torx bit for genuine Torx fasteners and the security hex bit where retention pins or tamper-resistant heads are present. Avoid excessive torque beyond the fastener or tool rating to prevent tip deformation. Regularly check tips for rounding and replace bits when wear affects fit.
