Tungsten steel shank — available in 12.7 mm (1/2') and 6.35 mm (1/4') diameters, total length 40–70 mm. Key benefits Durable material: made from tungsten steel for wear resistance and long service life under repeated use. Precision fit: two standard shank sizes (12.7 mm / 1/2' and 6.35 mm / 1/4') for reliable clamping in compatible chucks and collets. Flexible length options: available in total lengths from 40 to 70 mm to suit different reach and clearance requirements. Stable performance: solid construction reduces play and vibration, improving control and consistency during use. How this solves common problems Eliminates frequent shank wear and replacement by using a tougher material than standard steels. Provides a secure, consistent mount in standard 1/2' and 1/4' tool holders to reduce runout and improve accuracy. Length options let you choose the right reach without compromising rigidity or access. Typical applications Workshop and production drilling: use in drill presses or hand drills that accept 1/2' or 1/4' shanks for metal and wood tasks. Rotary tooling and routing: fits collets on routers and rotary tools for precise operations where a stable shank is required. and maintenance: ideal for swapping into existing tool setups during field repairs or equipment maintenance where durability matters. Specifications Shank diameter: 12.7 mm (1/2') and 6.35 mm (1/4') Total length: 40–70 mm Material: Tungsten steel guidance Choose the shank diameter that matches your tool's chuck or collet (12.7 mm / 1/2' or 6.35 mm / 1/4'). Select the total length (40–70 mm) based on the reach and clearance needed for your application. Reliable, hardwearing shanks designed for standard tool holders and demanding use.
