This AB Tools 11.0mm Rethreading Tap Extension Sleeve is designed for professional mechanics and DIY enthusiasts who need to work with taps in confined or hard-to-reach spaces. Its primary benefit is providing the necessary reach to engage taps in deep-set areas, preventing the need to dismantle surrounding components. A key consideration is that it requires a tap with an 11.0mm square drive end for proper fitment. Key features include its durable DIN 377 steel construction, a 150mm total length, and compatibility with square drive hand and machine taps.

This extension is designed for taps with an 11.0mm square drive end, typically corresponding to taps for approximately M18 threads.
The total length of the tap extension sleeve is 150mm.
It is manufactured from DIN 377 steel and is fully hardened for maximum strength and durability.
It requires a tap wrench that fits the square drive end of the extension. The extension itself has a square drive for this purpose.
It is suitable for use with both square drive hand and machine taps, as well as other threading tools.
This tap extension is made in Germany.
The tap's square end should be firmly inserted into the sleeve. The design relies on a precise fit between the tap's square drive and the internal dimensions of the sleeve.
Ensure the tap has an 11.0mm square drive end. Verify that the tap's square end is not damaged or excessively worn. Clean both the tap's square end and the inside of the sleeve.
Confirm that the tap's square drive is fully seated within the sleeve. Check for any debris preventing a flush fit. The sleeve is designed for a precise fit; significant looseness may indicate wear on either the tap or the sleeve.
Ensure adequate lubrication is applied to the tap and workpiece. Check that the tap is aligned correctly with the hole and not cross-threading. Verify the tap wrench is securely attached to the extension.
Discontinue use immediately. Continued use of damaged tools can lead to further damage to the workpiece or cause injury. Replace the extension if any cracks, significant deformation, or excessive wear on the drive surfaces are observed.
