Key benefits Faster, cleaner threading: Onepiece design performs internal and external threading at the same time, reducing tool changes and cutting job time. Works with standard drills: Compatible with both electric and manual drills so you can use existing or portable tools. No adapter needed for 19 mm hoses: Specifically sized for common 19 mm hose fittings, eliminating the need to switch or adapt tools. Reliable, repeatable results: Hardalloy cutting edge produces smooth cuts with low cutting force and creates uniform grooves for consistent threads. Built to last and safe to use: Heavyduty forged body plus an ergonomic, nonslip grip improves stability and prevents slipping during tapping. What it does and why you need it Simultaneous internal and external threading speeds up repairs and installations by combining two steps into one tool. This reduces downtime and the number of tools you must carry. The hardalloy cutting edge minimizes the force required to cut, which lowers operator fatigue and helps maintain precise thread profiles. The heavy forged construction resists deformation under load, so the tool stays accurate and dependable over repeated use. The ergonomic nonslip grip increases control when using power or hand drills, improving safety and finish quality. Compatibility and materials Size: Designed for common 19 mm hose fittings (no adapter required). Material: Hardalloy cutting edge for smooth, durable cutting; heavyduty forged body for structural strength. Tool type: Onepiece threading/tapping tool compatible with standard electric and manual drills. Typical applications Onsite hose : Quickly rethread damaged 19 mm garden or utility hoses with a cordless drill, avoiding lengthy replacement. Automotive and equipment maintenance: Recondition external and internal hose fittings on coolant, vacuum, or ancillary lines in the or roadside. Workshop production or maintenance: Efficiently produce or restore threads on batches of 19 mm hoses or fittings with consistent results. Practical features Onepiece construction reduces losing parts and simplifies setup. Low cutting force and uniform grooves mean fewer reworks and cleaner assemblies. Ergonomic nonslip grip gives better control when using power tools or hand drills. Use this tool when you need a fast, durable, and straightforward solution to thread 19 mm hoses without adapters, while keeping compatibility with standard electric and manual drills.
