Bits PH3 x 25 mm: 851/1 BDC SB

To drive screws properly, the tip of the bit must fit the screw head exactly. The right size prevents the bit from slipping out of the screw or damaging the cross head. Below you can read what to look out for.

What does PH 3 mean on a bit?

PH stands for Phillips, the well-known cross profile that is widely used for screws in wood, sheet material and metal. The number that follows is the size of the tip. The higher the number, the larger the tip and the larger the matching screw head. PH 3 is therefore intended for larger Phillips screws than PH 1 or PH 2. Always check the size of the screw head before you choose a bit.

Bits ph3 25 mm and the length of 25 mm

The length of 25 mm is the common standard length for loose bits. Such a short bit is sturdy and often also fits in places with little space. If you need to drive screws in a hard-to-reach place or a recessed opening, a longer bit or an extension is more convenient. For screwing on open surfaces, 25 mm is usually sufficient.

Proper use and maintenance

Only use a bit for the profile it is intended for, and press the bit straight into the screw head while turning. A worn or rounded tip increases the risk of slipping and damaged screw heads. Replace a bit in good time. It can be useful to keep several on hand if you often work with the same screw size.
