Wiha 32-Pc GoBox TerminatorBlue Impact Bit Set w/ Mini Ratchet (76889) is a professional-grade fastening system built for both impact driver use and precision manual fastening in confined spaces. Designed around Wiha's TerminatorBlue torsion technology, this set helps manage the torque peaks created by high-impact tools by allowing each bit to flex under load. This reduces stress on the tip, lowers the risk of premature breakage, and greatly extends service life in demanding industrial, automotive, and construction environments. The set also includes a compact 72-tooth mini-ratchet, making it equally effective for hand-tool applications where standard drivers or drills cannot fit. Key Features and Benefits: TerminatorBlue torsion zone: Energy-absorbing bit design flexes under load to reduce tip breakage and improve impact performance. 72-tooth mini-ratchet: Compact 3.5-inch reversible ratchet provides smooth manual fastening with only a 5¡ arc swing. CVM premium tool steel: Chrome Vanadium Molybdenum steel construction delivers high strength and long-term wear resistance. Precision-machined tips: Exact-fit bit geometry reduces wobble and helps minimize cam-out and stripped fasteners. Dual-purpose system: Suitable for both high-torque power tool work and low-clearance manual fastening tasks. Rugged GoBox storage: Pocket-sized metal case with molded tray keeps all 32 pieces organized and protected. Universal 1/4-inch compatibility: Standard hex interface supports broad use across drills, impact drivers, bit holders, and manual ratchets. Specifications: SKU: 76889 UPC: 084705768892 Weight: 0.74 lb Width: 2.00" Length: 4.25" Height: 1.38" Material: Chrome Vanadium Molybdenum (CVM) Steel Drive Size: 1/4-Inch Hex Ratchet Teeth: 72 Arc Swing: 5¡ Hardness Tolerance: +/- 1 HRC Included in Set: 1/4-inch Hex to 1/4-inch Square Adapter, 1/4-inch Drive Locking Magnetic Bit Holder, 72-Tooth Reversible Mini-Ratchet, Phillips Bits (#1, #2, #3), Square Bits (#1, #2, #3), Pozidriv Bits (#1, #2, #3), Torx Bits (T10, T15, T20, T25, T27, T30, T40), Hex Metric Bits (3.0, 4.0, 5.0, 6.0mm), Hex Inch Bits (1/8, 9/64, 5/32, 3/16, 7/32, 1/4Ó), and pocket-sized metal storage case with molded tray How to Use: Select the bit: Identify the correct fastener type and size, then remove the matching bit from the molded tray. Use for manual fastening: Insert the bit directly into the 1/4-inch hex head of the mini-ratchet and set the direction with the thumb lever. Use with power tools: Insert the bit into the locking magnetic bit holder, then attach the holder to your impact driver or drill. Use with sockets if needed: Insert the hex-to-square adapter into the ratchet or bit holder before attaching a 1/4-inch drive socket. Seat the bit fully: Make sure the bit is fully engaged in the fastener head before applying torque. Store after use: Return all parts to their designated positions in the GoBox and close the case securely. Benefits of Using Wiha 32-Pc GoBox TerminatorBlue Impact Bit Set w/ Mini Ratchet (76889): Longer bit life: Torsion-zone construction helps the bits survive repeated shock loads far better than standard bits. Fewer work interruptions: Reduced bit breakage means less downtime spent replacing worn or snapped bits. Safer fastening: Exact-fit tips help reduce cam-out, protecting the user, the fastener, and the surrounding surface. More versatility: One compact set covers manual ratcheting, impact driving, and light socket applications. Better portability: Metal GoBox case keeps the full assortment organized in a compact format that fits easily into a pouch or pocket. Improved access: Mini-ratchet design makes fastening possible in spaces where larger tools cannot operate effectively. Features: Computer-controlled heat treatment: Ensures consistent hardness and predictable performance across the bit set. Fast-action thumb lever: Allows one-handed directional changes on the mini-ratchet during tight-access work. Locking magnetic bit holder: Uses a mechanical lock to keep bits securely retained during demanding tasks. Standard 1/4" hex drive: Compatible with most modern drills, impact drivers, and manual bit tools. High-contrast organization: Molded tray layout helps users identify, access, and return bits quickly. Impact-rated construction: Bits and holder are built to handle the torque and vibration of impact tools.
