Screwdriver bits Bosch BITS R1 XH L:89mm set of 3 — Bosch 2608521117

Set of three Bosch screwdriver bits BITS R1 XH, each 89 mm long, designed to reach recessed and hard-to-access screw heads. These bits are intended for use with compatible power drivers and manual bit holders and provide extended length for construction, assembly and repair tasks that require deeper reach than standard bits. The set includes three identical long bits that maintain alignment and drive stability for cross-head fasteners.

Advantages

Long 89 mm length allows access to screws located in deep or narrow recesses without removing surrounding components. Precision-machined tips ensure consistent fit with compatible screw profiles, reducing cam-out and wear. Robust material construction provides resistance to twisting and deformation under typical torque loads, while the uniform length and shape make them convenient to use in power tools and manual holders.

Suitable for

• Driving and removing screws in recessed assemblies
• Construction and carpentry tasks requiring extended bit reach
• Electrical and plumbing installations with confined access
• Furniture assembly and repair where screws are set deep
• General maintenance and workshop use with power drivers

Key specifications

• Quantity: set of 3 bits
• Bit length: 89 mm
• Bit type: long screwdriver bits suitable for cross-head screw profiles
• Compatibility: designed for use with standard 1/4" hex bit holders and compatible power drivers
• Application areas: construction, assembly, repair, maintenance

How to use

Insert a bit into a compatible 1/4" hex bit holder or the quick-change chuck of a power driver until it seats securely. Select the appropriate rotational speed and torque setting on the driver for the screw material and size, then engage the screw head, keeping the tool aligned with the fastener to minimise slipping. For removal, run the driver in reverse at a controlled speed while maintaining axial pressure. After use, store the bits in a dry place to prevent corrosion and check tips for wear before reuse.

Usage recommendations

Use appropriate torque settings and steady alignment to prevent tip damage. Replace bits if the tip shows rounding or deformation. For best results in confined or recessed areas, pair these 89 mm bits with a bit holder extension or flexible adapter when additional reach or angular access is required.
