Screwdriver bit Bosch Screwdriver bit extra hard T27 152mm

The Bosch Screwdriver bit extra hard T27 152mm is designed for durability and precise fastening in professional and DIY applications. The 152 mm length and 1/4" (6.35 mm) hex shank provide compatibility with a wide range of screwdriver drivers and holders, while the Torx T27 tip ensures a secure engagement with matching fasteners.

Advantages

The extra hard steel construction and tapered torsion zone resist wear and absorb torque peaks, reducing the risk of tip breakage and cam-out. Its extended length allows better access in recessed or hard-to-reach fastening points and provides improved control when driving screws.

Suitable for

• Torx T27 screws in wood, metal and plastic
• Assembly and disassembly tasks requiring extended reach
• Professional tradespeople and home DIY projects

Key specifications

• Tip type: Torx T27
• Length: 152 mm
• Shank: 1/4" hex (6.35 mm)
• Material/hardness: extra hard steel with tapered torsion zone

How to use

Insert the 1/4" hex shank into a compatible bit holder or screwdriver chuck until it locks. Align the Torx T27 tip with the screw head and apply steady axial pressure while driving at an appropriate speed and torque setting. For best results, ensure the bit and screw are clean and undamaged before use.

Recommendations

Use the extra hard bit for tasks with frequent torque peaks and when extended reach is required. Avoid excessive lateral force to prevent premature wear; replace the bit when tip deformation or rounding is visible.
