Osg 2807408 Spiral Point Tap 6-32 Unc Ticn Hss

Product Description

The OSG 2807408 is a spiral point tap designed for threading 6-32 UNC holes in a wide range of metallic materials. It features a 2-flute geometry with a plug chamfer, a TiCN (Titanium Carbonitride) coating over a Vanadium High Speed Steel (HSS-E) body, and an H2 thread limit for close tolerance control. The overall length is 2 inches with a thread length of 0.6875 inches (11/16 inches) and a shank diameter of 0.141 inches. Right-hand cut with a 3B class of fit, this tap is suited for production and precision tapping applications where dimensional accuracy and tool life are priorities.

The OSG 2807408 is commonly used in machine shops, maintenance environments, and manufacturing operations. It is well-suited for through-hole and blind-hole tapping in aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, cast iron, stainless steel, and hardened steel. The spiral point geometry pushes chips forward ahead of the tap, making it most effective in through-hole applications with consistent chip clearance.

Key Features

• TiCN coating improves surface hardness and reduces friction, extending tool life in abrasive and harder materials
• Vanadium High Speed Steel (HSS-E) body provides toughness and wear resistance beyond standard HSS
• H2 thread limit ensures consistent fit within 3B class of fit tolerance for precision threading
• Spiral point geometry pushes chips forward, reducing chip packing in through-hole applications
• Right-hand cut, 6-32 UNC thread form for standard unified coarse thread production
• Coolant-through design not required, compatible with flood or manual lubrication

Compatibility

Designed for tapping 6-32 UNC threads in aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, and cast iron. No interrupted thread or oversize configuration.

Installation Notes

Installation of threading taps should be performed by a machinist or qualified trade professional using a properly sized tap wrench, tapping head, or CNC spindle set to the correct RPM for the material and tap diameter. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct minor diameter for 6-32 UNC before tapping. Apply appropriate cutting fluid or tapping lubricant to extend tool life and improve thread quality. Inspect the tap for wear or chipping before each use to avoid thread damage or tap breakage.
