Bits PH2 25 mm: 851/1 BDC SB

The bit is suitable for anyone who regularly drives screws into, for example, wood, sheet material or assembly work. Below you can read what to look for when choosing a bit, so that you avoid unnecessary wear or damaged screw heads when screwing.

What does PH 2 mean?

PH stands for Phillips, the cross-head profile in which the tip of the bit fits into the cross-shaped recess of the screw. The number 2 indicates the size of the tip. A bit works best when its size matches the screw head exactly. A bit that is too small or too large fits loosely, which increases the risk of slipping and damaged heads. Also note the difference with Pozidriv (PZ), as that profile looks like Phillips but fits slightly differently.

Why a bit of 25 mm?

A length of 25 mm is the common standard length for bits that you place in a bit holder or directly in the machine. The short version is compact and handy for work in places with little space. If you need to drive screws that are deeply recessed or hard to reach, a longer bit or an extension is more practical.

How to make a bit last and work neatly

Place the bit straight on the screw and apply even pressure while turning. A bit placed at an angle slips more easily and therefore wears out sooner. With a cordless screwdriver, set the clutch to suit the job, so that you do not strip the screw head. Replace a bit as soon as the tip is visibly rounded or damaged, because a worn bit also damages the screws.

Frequently asked questions

Which screws is a PH 2 bit intended for?

For screws with a Phillips cross head in size 2. Check the screw head carefully, as Pozidriv screws require a PZ bit.

Does this bit fit my cordless screwdriver?

Bits of this type are placed in a standard bit holder or in the chuck of the machine. If in doubt, check the chuck of your own machine.

How do I know a bit is worn?

If the tip is rounded, the cross shape is visibly worn out or the bit keeps slipping out of the screw, it is time for a new one.
