What is impact?
On standard driver bits, the tip absorbs all the concentrated torque. High impact loading leads to distorting, rapid tip failure and breakage. Thunder Zone impact driver bits, with an engineered spiral torsion zone distribute the applied impact evenly throughout the torsion zone, allowing higher impact loads and greatly extended bit life.

Features:

• All bits are magnetized - helping the bit grip the screw and prevent cam-out
• Compression forged tip - for an ideal fit and to reduce breakage
• Patented spiral impact zone - to distribute torque evenly
• Full body hardness - for a longer service life
• Premium quality S2 raw material
• SQ3 X 25mm
