Precision threading for through-hole applications. The OSG Metric Fine A-OIL-Spiral Point Tap delivers exact, durable threads for demanding materials, built for machinists and engineers who rely on consistent performance.

• Size & Thread: M18 x 1.5, metric fine-thread for precise engagement
• Through-Hole DIN374: optimized for through-hole work in line with the DIN374 standard
• Spiral Point A-OIL: spiral point geometry with OIL lubrication to push chips forward and improve cutting action
• Material: powder metal body for high strength and durability in tough use
• Coating: TiCN coating delivers exceptional wear and heat resistance, extending tool life
• Drive: right-hand thread for standard threading in most assemblies
• Chip Evacuation: optimized flute geometry enhances chip removal in through-holes
• Lubrication: OIL-Spiral design improves lubrication across threads, reducing friction and heat buildup

These taps enable clean, accurate threads with fewer passes and reliable performance in demanding materials. The TiCN coating minimizes wear and heat generation, while the powder-metal body stands up to repeated use. With the combination of spiral-point geometry and enhanced lubrication, you’ll benefit from smoother cuts, better chip control, and longer tool life—ideal for fine-thread work in aluminum, stainless steel, and alloy steels, as well as other through-hole applications defined by DIN374.
