Ponta de chave de fendas Wera PH para furo profundo 89 mm 05 059795 001 1/4 polegadas – ponta Phillips para furo profundo, 89 mm, encaixe de 1/4 polegadas

The Wera PH Tiefloch 89 mm 1/4" screwdriver bit is a Phillips deep-reach bit engineered to access screws set deep inside housings, recessed panels or assemblies with limited clearance. With an 89 mm shaft length and a 1/4" hex drive interface, the bit is compatible with common bit holders, ratchets and power drivers that accept 1/4" bits. The tip profile is made to engage Phillips head screws securely while the extended length allows work in tight, hard-to-reach locations.

Advantages

The extended 89 mm length provides reliable reach into deep holes and recessed screw positions without the need for improvised extensions. The 1/4" hex drive ensures broad compatibility with manual and powered drivers. Precision-formed Phillips tip promotes consistent engagement with PH screw recesses, reducing cam-out and wear under normal use. The bit construction offers balanced stiffness for controlled torque transmission while maintaining sufficient flexibility for alignment in confined spaces.

Suitable for

• Fastening and unfastening Phillips screws recessed in metal or plastic housings
• Assembly and maintenance tasks in electronics, appliances and automotive trim
• Work in cabinets, enclosures or machinery where screw heads are set deep from the access point
• Use with 1/4" bit holders, quick-change chucks and compatible power drivers

Key specifications

• Tip type: Phillips (PH)
• Overall length: 89 mm
• Drive interface: 1/4" hex
• Material and hardness: engineered steel appropriate for hand and light power use
• Intended fit: standard PH screw recesses

How to use

Select the correct Phillips size to match the screw recess, insert the bit into a compatible 1/4" bit holder or driver, and align the tip with the screw head. Apply steady axial pressure and turn the driver slowly at first to ensure correct engagement before applying higher torque. When using power drivers, set torque limits appropriate to the screw and material to avoid stripping the head or overdriving. After use, store the bit in a holder or tool organizer to protect the tip geometry.

Recommendations

Use the bit with the correct Phillips size for each screw and avoid excessive sideways force; when using high-speed impact drivers or high torque settings, check compatibility with the driver and consider using a bit designed specifically for impact use if required.
