Hexagonal Thread Drill Rod 25mm Carbon Steel Quenching Tempering
Extension rods, also known as extension drill steel, extension drill rod, extension steel, and M/F rod (Speedrod), feature either hexagonal or round cross-sections. Hexagonal rods offer superior weight and rigidity for efficient energy transfer and improved flushing, while round rods are lighter and typically used for extension drilling applications.
- Carburization heat treatment enhances strength and durability for high-speed percussion drill components
- Complete surface hardening (internal and external) extends component lifespan
- Process involves heating above steel transformation temperature for carbon penetration
- Forms durable compounds that significantly increase overall strength
