Impact screwdriver bit T20 25 mm S2 by Tvardy — box of 10

Impact screwdriver bit T20, 25 mm length, made from S2 tool steel by Tvardy, supplied in a box of 10 pieces. This bit is designed for use with impact drivers and heavy-duty screwdriving applications, compatible with screws that require a Pozidriv/PH T20 profile. Its S2 tool steel construction provides increased hardness and torsional strength for repetitive fastening tasks in construction, assembly, and repair work.

Advantages

The S2 tool steel composition ensures greater wear resistance and elevated strength compared with standard bits, reducing the likelihood of chipping or deformation under high torque. At 25 mm length the bit balances reach and control for use in confined spaces while fitting standard 1/4" hex chucks. Supplied in a box of 10, the set offers convenient storage and quick bit replacement on job sites or in workshops.

Suitable for

• Driving Pozidriv/PH T20 screws with impact drivers and cordless screwdrivers
• Construction and carpentry fastening tasks
• Machine assembly and industrial maintenance
• Repair and renovation work where repeated high-torque fastening is required

Key specifications

• Bit type: Impact screwdriver bit with Pozidriv/PH T20 profile
• Length: 25 mm working length
• Material: S2 tool steel for increased hardness and torsional strength
• Quantity: 10 pieces per box
• Shank: Standard 1/4" hex shank for compatibility with impact driver chucks and bit holders

How to use

Insert the 1/4" hex shank of the T20 bit into the impact driver or bit holder until it locks securely. Select the appropriate torque and speed settings on your tool based on the screw type and work material. Position the bit firmly in the screw head, apply steady pressure, and operate the impact driver in short bursts to control penetration and avoid cam-out. Replace bits from the box when wear or rounding of the profile is observed.

Usage recommendations

For best results use with impact drivers rated for high torque and choose torque settings suitable for the screw and substrate. Regularly inspect bits for wear and replace damaged bits to maintain fastening accuracy and avoid screw head damage.
