Torx 15 bit 50 mm (867/4 Z SB)

Which screws is a T15 bit intended for?

The designation T15 refers to the size of the Torx profile. Only a screw of the same size fits snugly. A bit that is too small or too large leaves play, which increases the risk of damage to the screw head and to the bit itself. Therefore always check the size on the packaging or in the specifications of the screws you are working with.

Why the length of 50 mm matters

With 50 millimetres you can reach screws that sit deeper or are harder to access, for example in a recess or behind an edge. A longer bit also helps if your bit holder or machine otherwise gets in the way. For regular screwing work in open space, a shorter bit is often more stable, as it is less likely to wander.

How to make a bit last longer

Push the bit straight into the screw head with even pressure and keep the machine in line with the screw. This way the profile wears down more slowly. Do not use the bit for screws that do not match its size, and replace it as soon as the profile becomes visibly rounded or damaged, because a worn bit also damages screws.
