Regal Cutting Tools 015004AS Acme Thread Tap 3/4-6 4 Flute

Product Description

The REGAL CUTTING TOOLS 015004AS is a straight-flute Acme thread tap engineered for cutting 3/4-6 Acme threads in a right-hand direction. Built from high speed steel with a bright finish, this tap delivers consistent thread form in moderate-to-hard ferrous and non-ferrous materials. It features a plug chamfer with 4 flutes and a 29-degree thread angle, matching standard Acme thread geometry. At 7-15/16 inches overall length, it is sized for use in a standard tap wrench, drill press, or CNC tapping setup. Machinists and maintenance technicians use this tap for producing lead screws, power transmission threads, and other Acme-form applications.

The 015004AS is suited for both production and repair threading work in shop and field environments. The plug chamfer style makes it appropriate for through-hole applications and for entering partially threaded blind holes where some lead-in length is acceptable. Class of fit 2G provides a standard commercial tolerance suitable for most Acme thread assemblies requiring moderate clearance and reliable engagement. The tandem-compatible design supports use in tandem tap sets for deep or difficult threading operations.

Compatibility

Designed for cutting standard 3/4-6 Acme right-hand threads to a 2G class of fit in through-hole and appropriate blind-hole applications across general machining and power transmission repair work.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Power down and secure the workpiece before beginning any tapping operation. Use appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Inspect the tap for wear or chipping before each use and never force a tap that has stopped advancing, as breakage may result.
