Technical Notes:

• Spiral point design pushes chips ahead of the tap, suitable for through-hole applications
• HSS-E construction provides heat resistance and durability
• TiCN coating option reduces friction and extends tool life
• 6HX hexagonal shank for secure tool holding
• Conforms to GB/ISO dimensional standards
• B chamfer (4-5-6-B) for general purpose threading

Applications:

Suitable for threading operations in steel, stainless steel, cast iron, and non-ferrous metals. Recommended for through-hole threading where forward chip evacuation is required.
