Bosch Extension for spade bits Bosch 2608595422 Length 152 mm Size 1 inch

The Bosch Extension for spade bits is a purpose-built accessory that increases reach for spade-bit drilling tasks. With an overall length of 152 mm and a 1-inch socket size, the extension fits standard spade bits to enable deeper holes without requiring longer drill bodies. The tool is intended to maintain reliable connection between the drive and the spade bit while allowing access into confined or recessed work areas.

Advantages

The extension offers additional working length that helps reach deeper positions and recessed fixture points. Its standardized 1-inch size ensures compatibility with common spade bits and quick interchangeability. The compact 152 mm length balances extended reach with manageable control and reduced wobble compared to overly long adaptors. The design supports stable torque transfer from the drill to the bit, preserving cutting efficiency.

Suitable for

• Drilling deeper holes in wood and timber framing
• Accessing recessed or hard-to-reach screw and bolt locations where a longer bit is needed
• Electrical and plumbing installations that require precise hole placement through joists or studs
• Carpentry and joinery tasks where standard spade bits alone cannot reach

Key specifications

• Overall length: 152 mm
• Socket/size: 1 inch
• Compatibility: designed for use with standard spade bits
• Function: extension for deeper drilling and improved reach

How to use

Insert the shank of a compatible spade bit into the 1-inch socket of the extension and secure it according to the drill and bit manufacturer's instructions. Mount the extension into the drill chuck until firmly seated. Start drilling at low speed to establish the hole, then increase speed as needed while maintaining steady pressure. Withdraw the bit periodically to clear chips and reduce heat build-up. Ensure the drill is suitable for use with spade bits and extensions before applying high torque.

Usage recommendations

Use the extension with appropriately sized spade bits and avoid excessive side loading or twisting motions. For longer continuous drilling, pause periodically to remove debris and allow cooling. Wear eye protection and follow standard safety precautions for power drilling.
