Knipex 9T 89931 Precision Screwdriver

The Knipex 9T 89931 is an insulated precision screwdriver with a slotted 1/16 inch tip. It features a round shank and an overall length of 4 1/4 inches. The handle uses high alloy chrome vanadium steel with a matte chrome finish and black oxide tips. This hand tool is built for precise fastening tasks where electrical insulation is required.

Suited for insulated slotted work only

Electricians and technicians performing live electrical work up to the rated voltage will find the insulation essential. The non-magnetic tip avoids interference with sensitive components. Buyers needing Phillips, Torx or hex profiles cannot use this driver. Workers requiring ESD-safe or non-sparking rated tools must select a different model.

1/16 inch slotted tip width

The 1/16 inch tip width is the single specification that determines fastener compatibility. It fits only slotted screw heads matching this exact dimension. Using it on wider or narrower slots risks damaging the fastener or the tool tip. Verify the screw slot size before purchase to ensure a correct fit.

Questions about this item

Should I choose the 1/16 in slotted tip or another size for precision work?

The 1/16 in slotted tip is suited for very small fasteners common in electronics and fine mechanical assemblies.

What does the 4 1/4 in overall length mean when I am working inside a tight enclosure?

The compact length keeps the handle close to the tip, giving better control and access in confined spaces.

How does the insulated shaft protect me when working near live circuits?

The insulation on the shank guards against accidental contact with energised parts up to the rated voltage.
