Osg 1754708 Spiral Flute Tap 8-32 Unc Powdered Metal

Product Description

The OSG 1754708 is a spiral flute tap designed for cutting 8-32 UNC internal threads in demanding materials. Built from powdered metal and finished with a TICN (Titanium Carbon Nitride) coating, this tap handles alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloys. The modified bottoming chamfer allows threading closer to the bottom of a blind hole. With a right-hand thread direction, a 15-degree helix angle, and an H4 thread limit, this tap suits precision threading work performed by machinists and maintenance technicians in production and repair environments.

This tap is suited for moderate- to high-difficulty threading applications in blind holes where a standard bottoming or plug tap may not provide enough thread depth control. The 2-flute spiral design efficiently evacuates chips upward during the cut, reducing the risk of chip packing in blind-hole applications. It is well matched to CNC tapping operations and hand-tapping setups in shops working with aerospace, automotive, and industrial alloys.

Key Features

• 8-32 UNC thread form with right-hand thread direction
• 2-flute spiral design promotes upward chip evacuation in blind holes
• Modified bottoming chamfer for threading close to hole bottom
• Powdered metal construction with TICN coating for extended tool life in hard and abrasive materials
• H4 thread limit for consistent tolerance control
• 15-degree helix angle suited to a range of workpiece materials including titanium and high-nickel alloys

Compatibility

Designed for threading 8-32 UNC blind holes in alloy steel, stainless steel, hardened steel, titanium, and high-nickel alloy workpieces. Part of the OSG EXOTAP 313 series.

Installation Notes

This tap should be installed and operated by qualified machinists or maintenance technicians familiar with tapping procedures and feeds and speeds for the target material. Power down or disengage any machine before mounting the tap in the chuck or holder. Use a tapping fluid or cutting oil appropriate for the workpiece material, particularly when working with stainless steel, titanium, or high-nickel alloys. Inspect the tap for wear or chipping between uses, as TICN-coated powdered metal tools in hard materials can show edge wear that is not always visible without magnification.
