Guhring 9048830160000 Spiral Flute Tap M16x2 Cobalt

Product Description

The GUHRING 9048830160000 is a spiral flute tap designed for blind hole threading in a wide range of metallic workpiece materials. Built from cobalt high-speed steel and finished with GUHRING's proprietary Ignator coating, this tap is engineered for durability and performance in demanding production environments. It cuts an M16x2 metric right-hand thread to a 6H class of fit with a D7 thread limit. The 40-degree helix angle and fast flute style promote efficient chip evacuation in blind holes. Licensed machinists and tool-and-die professionals typically specify this tap for applications where thread quality and tool life under load are critical.

This tap is suited for blind hole threading operations across a broad range of workpiece materials including alloy steel, alloy tool steel, aluminum alloy, case-hardened steel, cast iron, ductile iron, free-cutting steel, heat-treated steel, malleable cast iron, stainless steel, structural steel, and tool steel. The modified bottoming chamfer makes it appropriate for threading close to the bottom of a blind hole where a standard taper or plug tap cannot reach full thread depth. It belongs to GUHRING Series 4883 and is a single-piece package intended for individual replacement or tooling buildout.

Key Features

Compatibility

Designed as an OEM-style production tap for blind hole threading in metallic workpieces classified under material codes P, M, K, and N, covering steel, stainless steel, cast iron, and aluminum and non-ferrous alloys.

Installation Notes

Machinists should mount this tap in a rigid or floating tap holder appropriate for the machine tool in use and verify spindle alignment before cutting. Ensure the workpiece is securely fixtured and that the pre-drilled hole diameter matches the recommended tap drill size for an M16x2 thread. Apply a cutting fluid or tapping compound appropriate for the workpiece material before and during operation. Do not reverse-drive the tap dry or exceed the manufacturer-recommended speed range for the material being threaded.
