Extension Tap: 3/8-24, 3 Flutes, H3, Bright/Uncoated, High Speed Steel, Spiral Point MPN:G859443

The extension tap's spiral point design provides accurate thread creation on hard or challenging materials, making it valuable to machinists working with aluminum, stainless steel or hardened alloys that require specialized tools like HSS (High-Speed Steel) to prevent damage. Its high class H3 specification offers precision tolerances for high volume automotive manufacturing industries, while its bright/uncoated surface increases lubrication effectiveness during cutting minimizing slippage while creating threads across production lines saving time and material expenses ensuring accurate component fits reducing defects in assembly or end-user quality issues.
