Tvardy impact bit PH3 50mm S2 (pack quantities: 1/10/50/500)

Impact Phillips screwdriver bit PH3 by Tvardy, 50 mm length, made from S2 steel. This bit is designed for use with impact drivers and impact-rated screwdrivers to drive PH3 cross-head fasteners. The 50 mm length provides a balance between reach and control, while the S2 tool steel construction offers enhanced toughness and resistance to wear during high-torque fastening tasks. Packs are available in multiple quantities to suit single repairs or larger professional inventories.

Advantages

The S2 steel composition delivers increased durability and improved resistance to chipping and deformation under repeated impact loads. The PH3 geometry is precision-formed for consistent engagement with PH3 screws, reducing cam-out and improving torque transfer. The 50 mm length allows stable handling in power tools while giving enough reach for recessed fasteners. Multiple pack size options make it simple to replace worn bits or to equip crews and workstations with identical, reliable bits.

Suitable for

• Driving PH3 Phillips screws in wood, metal and composite materials
• Use with impact drivers and impact-rated cordless screwdrivers
• High-torque fastening tasks in construction, carpentry and mechanical assembly
• Workshop, service van inventory and professional toolkits

Key specifications

• Tip profile: PH3 (Phillips size 3)
• Length: 50 mm overall
• Material: S2 tool steel for impact applications
• Intended tool interface: 1/4" hex shank (compatible with standard bit holders and chucks)
• Designed use: impact drivers and impact-rated screwdrivers

How to use

Insert the 1/4" hex shank of the bit into the driver or bit holder until it locks or seats firmly. Align the PH3 tip with the screw head and apply steady axial pressure while operating the impact driver at appropriate speed and torque settings for the material and fastener size. Replace the bit when tip wear or deformation causes reduced engagement with the screw head to avoid damaging fasteners or driver.

Usage recommendations

For best results, use the Tvardy PH3 50 mm S2 impact bit with impact-rated drivers and select torque settings suitable for the screw and base material. Store bits in a dry, organized holder to prevent loss and inspect tips regularly for wear before use.
