How to use

Insert the Bosch 2607001660 bit into a compatible 1/4" hex bit holder or quick-change chuck until it locks. Align the T40 tip with the screw head and apply steady axial pressure while turning the driver. For impact driving, ensure the driver settings and screw type are appropriate for a T40 bit. Replace the bit when tip wear prevents secure engagement with screws.

Recommendations

Use the bit with properly sized T40 fasteners and avoid excessive side loading. For heavy-duty or continuous impact applications, check the bit regularly for wear and replace when signs of rounding or chipping appear to maintain safe and efficient operation.
