The OSG Metric A-LT-Spiral Flute Threading Tap is built for precision internal threads in blind holes, offering reliable performance in demanding metalworking tasks. Crafted with a powder metal body and a TiCN coating, it delivers durability and smooth cutting in challenging materials.

• Metric threading: M3 × 0.5 thread form designed for accurate, consistent internal threads in blind holes.
• Flute type: LT (Long Taper) spiral flute for superior chip evacuation and reduced clogging in deep holes.
• Material: Powder metal construction combines strength with toughness to resist wear under demanding cuts.
• Coating: TiCN coating increases hardness and wear resistance, lowering friction and extending tool life in high-speed machining.
• Cutting direction: Right-hand threading for standard, widely used assembly applications.
• Application focus: Optimized for accurate threaded holes in metal components where access is limited and hole depth is substantial.

In practice, this tap helps machinists achieve clean, true threads in blind holes with fewer passes and less tool chatter. The TiCN coating and powder metal composition work together to resist wear during repetitive threading tasks, improving consistency across production runs. Whether you’re repairing an enclosure, assembling precision machinery, or fabricating automotive components, this tap offers dependable performance, reduced cycle times, and longer tool life compared with uncoated or lower-grade alternatives.
