Professional bit set with bit holder (32 pieces)

Professional Bit Set in a Practical Box - Always the Right Bit at Hand

High-quality tool steel ✓ With colour ring marking ✓ Incl. magnetic bit holder ✓

With the Bohrcraft professional bit set, the right bit is always within reach. The bit set consists of 30 bits made from durable S2 steel, a square adapter for socket wrenches and a bit holder with locking mechanism, and is suitable for all cordless screwdrivers and drills with a drill chuck. With increasingly powerful cordless screwdrivers (e.g. from Makita, Metabo or Bosch Professional), which are now affordable even for ambitious DIY users, it is advisable to use screwdriver bits that can withstand high torques. Our high-quality bit set fully meets this requirement and is therefore ideal for heavy-duty use by tradespeople in the construction industry, industry and DIY users with high quality standards.

The 32-piece set consists of 30 high-quality bits in the most common drives and sizes. In addition to simple slotted bits, it also includes cross-recess bits for PH screws and PZ screws in the most common sizes. The set also contains internal hexalobular bits and internal hexalobular bits with hole. For screws with a hex socket drive, the bits are available in the market-standard sizes. For easy and quick bit changes, the bit set also includes a magnetic bit holder with a practical locking mechanism so that the bits do not constantly fall out of the bit holder during screwdriving. A square adapter for socket wrenches with a ¼ inch drive completes the extensive set.

The practical box made from robust ABS plastic should not be missing from any cordless screwdriver and is used for easy storage of the bits, so that they do not fly around loose in the screwdriver case or get lost. The slots for the individual bits provide a good hold and allow the required bit to be removed easily. To have the right bit quickly at hand, all slots are marked with a graphic representation indicating the corresponding size. Thanks to the rotatable belt clip, the handy box can be easily attached to a belt. This means that all screwdriver bits are always at hand when screws with different drives are used for screwdriving or disassembly work.

Meaning of the Colour Coding of Screwdriver Bits

High-quality bits are marked with a colour ring by many manufacturers to make it easier to select the suitable bit attachment. However, the colours are not standardised and may vary depending on the manufacturer. For example, a bit for cross-recess screws with PH drive may be marked with a blue ring by one manufacturer, while the same colour ring is used by another manufacturer for cross-recess screws with PZ drive. Some manufacturers also use colour rings to indicate the bit size. In our bit set, bits for the same screw profiles are each coded with a uniform colour ring, regardless of size.

An orange colour ring marks bits for conventional slotted screws

The four slotted bits from the set are marked with an orange colour ring and are suitable for normal slotted screws. It does not matter whether they are machine screws or wood screws. The shape of the screw head is also of secondary importance when selecting the suitable slotted bit. Slotted screws are among the classic screw types and are still used in many areas today.

A red colour ring marks bits for cross-recess screws with PH drive

Cross-recess screws with PH drive are widely used and are driven with suitable PH bits. Compared to a slotted screw, the internal cross recess reduces the risk of the screwdriver slipping sideways out of the screw drive. The four PH bits included in the bit set are marked with a red colour ring. The common size PH2 is included twice in the set, as it is used particularly often for many screws with PH drive. A well-known example is black drywall screws, which are usually used with mains-powered drywall screwdrivers to fasten plasterboard panels.

A blue colour ring marks bits for cross-recess screws with PZ drive

Cross-recess screws with PZ drive are particularly common in woodworking. Compared to the PH drive, the profile has a different design and is intended for higher force transmission. The main difference lies in the geometry of the bit: On PH bits, the flanks taper towards the tip, while PZ bits run out more straightly. In addition, fine secondary ribs are present between the main flanks, improving the fit of the bit in the screw profile. PH and PZ bits are therefore only compatible with each other to a limited extent. An incorrectly selected bit can quickly damage the screw drive. PZ screws are easy to identify by the additional cross on the screw head, offset by 45 degrees. They are often used with countersunk screws, chipboard screws, screen printing boards or wooden profiles for substructures in wall and facade applications.

A yellow colour ring marks bits for internal hexalobular screws

For screws with an internal hexalobular drive, a correspondingly suitable hexalobular bit is required. The six-lobed round tooth profile of the drive enables good torque transmission during screwdriving. Compared to cross-recess drives, the risk of damaging the screw drive is lower when using a suitable bit. In addition, less axial pressure needs to be applied to the bit tip. Internal hexalobular drives are therefore well suited for applications where high force transmission is required, for example with longer or larger screws. In our bit set, the yellow-marked internal hexalobular bits are included in seven sizes from T10 to T40.

A dark blue colour ring marks bits for internal hexalobular screws with security pin

A special variant is internal hexalobular bits with hole. The dark blue coded bits have the same outer profile as normal internal hexalobular bits, but additionally feature a centred bore. This bore accommodates the security pin in the screw drive. Such screws are used when loosening with simple standard tools is to be made more difficult, for example in equipment and plant engineering. Internal hexalobular bits with hole can generally also be used for normal internal hexalobular screws. The reverse is not possible, as a solid bit cannot be inserted deeply enough into the screw profile because of the security pin. These security bits are also included in the bit set in seven sizes from T10 to T40.

A yellow-orange colour ring marks bits for screws with hex socket

Screws with hex socket are familiar to almost everyone from furniture assembly. The suitable drive is operated with hex keys or HEX bits. A key advantage of this screw type is that the screw head can be very compact in relation to the screw drive. Headless grub screws, such as those used for example with spacers or profile connectors, are also often designed with a hex socket drive. Screws with hex socket are also often used when frontal screwdriving is difficult for space reasons. Depending on the installation situation, either suitable HEX bits or classic hex keys are used for this. The widespread use of hex socket screws in areas such as furniture assembly, bicycle mechanics, vehicle construction and profile technology ensures that suitable HEX bits should not be missing from any bit set.

ATTENTION: Always use the correct bit suitable for the screw. Unsuitable bits can damage the screw drive and the bit and render them unusable. Which bit is suitable is usually stated in the item description of the screw manufacturer or, when purchasing by the box, on the box.
