Regal Cutting Tools 008192AS Straight Flute Tap 8-32 Unc

Product Description

The REGAL CUTTING TOOLS 008192AS is a straight flute tap designed to cut 8-32 UNC internal threads in a wide range of materials. Built from high-speed steel with a bright, uncoated finish, this plug-chamfer tap features four flutes and a right-hand thread direction. It carries a 2B class of fit and an H3 thread limit, making it suitable for standard tolerance threading applications. With an overall length of 2.125 inches and a thread length of 0.75 inches, it is sized for typical machine screw thread work encountered in production and maintenance environments. Licensed machinists and tool-and-die professionals are the primary users.

This tap is used in both production shop and maintenance repair settings where 8-32 UNC threads are required. The plug chamfer - with a moderate lead-in - makes it appropriate for through-hole threading as well as blind holes with adequate clearance at the bottom. It is commonly used in light-duty metalworking, fixture building, and general machine assembly where 8-32 fasteners are standard. The bright, uncoated finish suits use in ferrous and non-ferrous materials with proper cutting fluid applied.

Installation Notes

This tap is installed by machinists and toolroom professionals using a tap wrench, tapping head, or CNC rigid tapping setup. Power down and de-energize any machine tool before loading or changing cutting tools. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Inspect the tap for chips or damage between uses and discard any tool showing signs of fracture or excessive wear.
