Screwdriver Bit MILWAUKEE BIT SHOCKWAVE TX20 90mm, single piece (MIL 4932430878)

MILWAUKEE BIT SHOCKWAVE TX20 90mm is a single-piece Torx TX20 screwdriver bit engineered for use with impact drivers and power screwdrivers. At 90 mm length, this bit provides extended reach for recessed or hard-to-access fasteners while ensuring solid engagement with Torx TX20 screw heads. The single-piece construction improves strength and reduces the risk of breakage under high-torque conditions, making it suitable for repetitive fastening tasks in construction, assembly and maintenance work.

Advantages

The single-piece design offers improved durability and torsional strength compared with multi-piece or welded bits, reducing wobble and wear during high-torque driving. The 90 mm length gives additional reach to access recessed screws without compromising control. Engineered for compatibility with impact drivers, the bit maintains secure fitment in the screw head for precise engagement and reduced cam-out. The Torx TX20 profile distributes driving force evenly across the screw head to minimize stripping.

Suitable for

• Driving Torx TX20 screws in furniture assembly and cabinetry
• Construction and framing tasks requiring recessed fastener access
• Mechanical and electrical maintenance where longer reach is needed
• Repetitive fastening operations with impact drivers or power screwdrivers

Key specifications

• Drive type: Torx TX20
• Overall length: 90 mm
• Construction: single-piece bit
• Intended use: compatible with impact drivers and power screwdrivers
• Finish and hardness: engineered for high-torque driving and wear resistance

How to use

Insert the bit securely into the chuck or bit holder of an impact driver or power screwdriver. Align the Torx TX20 tip with the screw head and apply steady pressure while driving at an appropriate speed for the material and fastener. For recessed screws, use the 90 mm length to reach the fastener while keeping the tool stable. Inspect the bit tip before use for wear or damage and replace the bit if the profile shows rounding or deformation to maintain secure engagement.

Usage recommendations

Use the bit with compatible impact-rated drivers and avoid excessive side-load or bending. Replace the bit when signs of wear or rounding appear on the tip to prevent screw damage. Store the bit in a protective holder or case to preserve tip geometry and extend service life.
