Hertel K090946AS Straight Flute Tap M6.3x1.00 Metric Coarse

Product Description

The HERTEL K090946AS is a straight flute tap designed for cutting M6.3x1.00 metric coarse internal threads in through-holes and blind holes where chip evacuation is managed manually or with cutting fluid. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread form in a range of workpiece materials. The plug chamfer style distributes cutting load across several leading threads, making it well suited for general-purpose tapping operations in production and maintenance environments. Overall length is 2.5 inches, and the D5 thread limit provides the tolerance class needed for standard metric fastener fits. This tap is installed and used by machinists, tool-and-die makers, and maintenance technicians.

This tap is used in machine shop, manufacturing, and field maintenance applications where M6.3x1.00 metric coarse threads are required. Straight flute geometry makes it appropriate for use in softer metals and materials where chips break short and do not need to be spiraled out of the hole. The plug chamfer entry is the standard choice for most through-hole and moderately deep blind-hole tapping tasks. Right-hand thread direction matches standard metric fastener convention. Suitable for use in hand tapping operations or with a tapping attachment on a drill press or CNC machine tool.

Compatibility

Designed as a standard replacement or production tap for applications requiring M6.3x1.00 metric coarse internal threads in ferrous and non-ferrous materials.

Installation Notes

Install and use this tap with appropriate cutting fluid or tapping compound for the workpiece material. Secure the workpiece and ensure the tap enters the hole square to the surface to avoid tap breakage or thread misalignment. Back the tap off periodically to break chips when hand tapping. Power down any machine tool and follow lockout procedures before changing or inspecting taps in a spindle.
