Screwdriver bit Impact
HERMAN SB-40 PH
For impact wrench

The flexible TorZon™ torsion zone on the shank reduces pressure on the tip:
the bit behaves like a strong spring when screwed in, minimising the possibility of breakage even under very high torque impacts from 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 almost eliminated

Precision-machined bit tip:
fits snugly into the head of the screw, minimising the possibility of damage to the head during screwing

Hardened from tip to shank:
the same properties over the entire length of the bit

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

Manufactured to DIN 3126, with ¼" (6.3 mm) hexagonal shank:
suitable for use with three-jaw chucks and compatible with all standard hexagonal bit holders (DIN ISO 1173-D 6.3)

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