These precision collets provide secure clamping for 1.6mm tungsten electrodes in WP17/18 torches. The split design maintains consistent pressure throughout thermal cycles. Machined from high-quality brass for excellent conductivity and durability. The tapered design ensures proper seating in the collet body. Sold in 5-packs for cost-effective inventory management. Ideal for precision TIG welding on thin gauge materials. Each collet is individually inspected for dimensional accuracy. Compatible with all standard collet bodies and back caps. The precision machining prevents electrode slippage during welding for stable arc performance.
