Wiha 24-Piece TerminatorBlue Impact Driver Bit Set w/ Belt Clip (70289) is a professional-grade impact bit set built for high-torque fastening with impact drivers and other power tools. Designed to reduce bit breakage and improve fastener engagement, this set uses Wiha's TerminatorBlue technology with an energy-absorbing torsion zone that flexes under heavy impact instead of transferring all the stress directly to the tip. This helps extend bit life and improve consistency during repetitive fastening work. Made from Chrome Vanadium Molybdenum (CVM) tool steel and organized in a compact case with a belt clip, the set is suited for mechanical, electrical, and construction use. Key Features and Benefits: Tuned torsion zone: Engineered to flex under high-impact loads, reducing stress at the tip and helping prevent breakage. High hardness tolerance: Heat-treated to 61 HRC ±1 for dependable strength, wear resistance, and long-term durability. Reduced cam-out: Precision-machined tips provide a tighter fit in fastener heads, helping reduce slipping and stripped screws. Industrial-grade material: CVM tool steel construction provides the strength needed for demanding professional applications. Portable storage: Compact case with integrated belt clip keeps bits organized and easy to carry on the job. Universal compatibility: Standard 1/4-inch hex drive works with most common impact drivers and drills. Specifications: SKU: 70289 UPC: 084705702896 Weight: 0.53 lb Width: 3.88 in Length: 8.25 in Height: 1.25 in Hardness: 61 HRC ±1 Drive: Standard 1/4 in. Hex Drive Included in Set: 24 Pieces (Phillips, Torx, Square, and Slotted Impact Bits); 1/4" Magnetic Bit Holder; Storage Case with Belt Clip How to Use: Select the bit: Choose the correct bit profile and size for the fastener you need to drive. Install the bit holder: Insert the 1/4-inch magnetic bit holder into the chuck of your impact driver or drill. Seat the bit: Place the selected TerminatorBlue bit into the magnetic holder until it is fully seated. Engage the fastener: Align the bit with the screw head and apply light forward pressure to keep it fully engaged. Apply torque: Operate the power tool and allow the torsion zone to absorb impact energy during fastening. Store after use: Return the bit to its assigned slot in the case and use the belt clip for convenient carry.
