Tool extension DIN 377 (4-sided, 3.4 mm, zinc-plated) by TECWERK — for hand taps and reamers The tool extension DIN 377 is a compact accessory designed to extend hand taps and hand reamers, zinc-plated for corrosion resistance and finished to DIN 10 / ISO square-shank dimensions for consistent manual torque transfer. Zinc-plated for corrosion protection Compatible with hand taps and hand reamers Square shank to DIN 10 and ISO Overall length 95 mm, standard DIN 377 Secure manual tapping with standards-based compatibility The extension is made to the DIN 377 standard and features a square shank produced to DIN 10 and ISO tolerances, which ensures a positive drive and repeatable torque when used with manual taps and reamers. By aligning with recognised standards, the accessory reduces slippage and wear on both tap and holder interfaces, supporting consistent thread quality in everyday workshop tasks. The measured geometry contributes directly to process reliability, making the accessory suitable for maintenance benches, small-series machining and repair work where predictable results matter. Durable finish for long service life in workshop environments Finished zinc-plated and constructed from material: zinc, the accessory offers basic corrosion resistance while remaining economical to replace should severe wear occur. The protective coating delays surface oxidation in typical workshop atmospheres and simplifies maintenance compared with untreated steel. For tasks that do not demand specialised coatings, the zinc finish provides a sensible balance between longevity and cost-effectiveness, supporting frequent manual operations without compromising handling or fit in standard holders. Compact length that improves access and handling With an overall length of 95 mm, the extension provides a practical reach for confined spaces while remaining easy to control by hand. The modest length reduces leverage and the risk of unexpected torque on delicate workpieces, assisting in accurate start-up of threads and controlled reaming. Compliance with DIN 377 means the accessory integrates smoothly into existing setups and storage systems, helping to streamline workflows and reduce setup time for manual threading and finishing operations.
