Cle-line C62156 Spiral Point Tap 10-32 Unf 2 Flute Hss

Product Description

The CLE-LINE C62156 is a spiral point plug tap designed for through-hole threading in machine tapping applications. Built from high-speed steel with a bright uncoated finish, it cuts a 10-32 UNF right-hand thread and is rated to an H3 thread limit for consistent tolerance control. The two-flute spiral point geometry pushes chips ahead of the tap into the through hole, reducing chip packing and improving thread quality. With an overall length of 2.375 inches and a thread length of 0.875 inches, this tap suits standard toolholders and tapping heads used in production and maintenance environments. Machinists, tool and die workers, and maintenance technicians are the primary users.

The C62156 is suited for through-hole threading operations on cast iron, non-ferrous aluminum, and steel workpieces. Its plug chamfer provides a gradual lead-in that distributes cutting load across several threads, making it well-suited for both machine tapping and hand tapping in a drill press or CNC machining center setup. The H3 thread limit designation ensures the tapped hole stays within standard tolerance range for UNF fastener fitment.

Key Features

• 10-32 UNF thread form with right-hand cut
• 2-flute spiral point design pushes chips forward in through-hole applications
• Plug chamfer distributes cutting load for smooth entry
• H3 thread limit for consistent tolerance control
• High-speed steel construction for general-purpose metal cutting
• Bright uncoated finish suitable for use with cutting fluids

Compatibility

Designed for through-hole threading in cast iron, non-ferrous aluminum, and steel. Fits standard tap wrenches, tapping heads, and machine tool holders accepting a 0.194-inch shank diameter.

Installation Notes

A licensed machinist or maintenance technician should ensure the workpiece is securely fixtured before tapping. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Align the tap perpendicular to the workpiece surface before applying torque to avoid tap breakage. For machine tapping, verify spindle speed and feed rate are appropriate for the material and tap size before starting the cycle.
