The Tomax PH3x50 mm Phillips Bit is a medium-length bit designed for PH3 standard Phillips head screws, used in electric, cordless, and impact screwdrivers. Unlike the PH2, the PH3 bit is used for larger screw heads and thus thicker screws that require higher torque. The 50 mm length provides access to deeper areas and a better viewing angle.
User Information and Key Features
This bit is indispensable for high-power and large screw applications:
PH3 Type (Phillips No. 3): This bit type is the largest standard Phillips screw size. It is typically used for thick and long screws in structural applications requiring high torque and strong fastening.
50 mm Length: This medium length helps prevent the body of the screwdriver from hitting the surface while allowing for a balanced and controlled start during the installation of large and long screws.
Target Audience:
Heavy Construction Professionals: For installing large structural screws that secure the rough framing, framework, and roof truss.
Carpentry and Joinery: For strong joining of thick wood or laminated materials.
Metalwork: For screwing and assembling thick sheet metal or steel profiles.
Industrial Assembly: Installation of heavy-duty machinery and equipment.
Usage Area and Sectors Used In
The PH3x50 mm bit stands out in specific applications requiring power and depth:
Primary Use Cases:
Structural Wood Screws: Thick screws used in wood framing that require high torque.
Concrete and Masonry Screws: Typically large-headed screws used for fastening to walls or concrete floors.
Machine Connections: High-strength screws used in the assembly of large machines and industrial equipment.
Sectors Used In:
Heavy Construction and Rough Framing: Assembly of structural elements.
Metallurgy and Fabrication: Joining thick metal sheets and profiles.
Heavy-Duty Furniture Manufacturing: Assembly of industrial shelving and large storage systems.
Material Properties and Technical Details
Since a PH3 bit is naturally exposed to more torque than a PH2, material durability is critically important:
Material: High-performance, highly alloyed S2 Tool Steel is used, specifically durable against impact. This material provides superior resistance to bending, breaking, and wear under the extreme torque applied to the bit.
Hardness and Durability: The bit undergoes heat treatment to a high hardness (typically 58-62 HRC) to ensure a perfect fit with the PH3 screw geometry and prevent wear. The structure of S2 steel offers a high level of toughness (resistance to breakage) despite this hardness.
Bit Geometry: The precisely machined PH3 geometry provides a perfect fit for large screw heads, definitively preventing cam-out during screwdriving.
Shank Type: The machine-insertable part is an industrial standard 6.35 mm (1/4 inch) hexagonal shank. This universal design prevents the bit from slipping in the holder, especially during high torque transfer.
