Screwdriver bit Impact
HERMAN Torx 25mm
For impact wrench

The flexible TorZon™ torsion zone on the shank reduces the pressure on the tip:
the bit behaves like a strong spring when screwed in, minimising the possibility of breakage even at very high torque impacts generated by impact drivers

Increased bit hardness:
resulting in very low wear and high strength, but a more brittle design despite optimised heat treatment. However, when combined with the flexible TorZon™ torsion zone, the susceptibility to bit breakage is largely eliminated

Precisely machined bit tip:
fits well into the screw head, minimising the possibility of damage to the screw during screwdriving

Hardened from tip to shank:
same bit properties throughout its length

Primary material - S2 material (chromium-silicon-manganese-molybdenum-vanadium steel):
ideal for extremely durable, high quality bits

With ¼" hexagonal shank (form C 6.3 according to DIN ISO 1173):
for 1/4" impact hexagonal bit holders (form D 6.3 according to DIN ISO 1173)

Surface finish / hardness:
black phosphated /HRC 59~60
