Guhring 9041220030000 Spiral Point Tap M3 X 0.5

Product Description

The GUHRING 9041220030000 is a spiral point tap designed for right-hand, through-hole threading in metric coarse applications. Built from powdered metal and coated with a titanium nitride (TiN) finish, this tap delivers hardness and wear resistance suited for threading high-tensile steel. It cuts an M3 x 0.5 thread to a 6H class of fit with a D3 thread limit, offering tight dimensional control for precision assemblies. The plug chamfer eases entry into pre-drilled through holes. Overall length is 2.205 inches, and shank diameter is 0.141 inches. Machinists and toolroom technicians in metalworking and manufacturing environments rely on this tap for consistent, repeatable thread quality in production and maintenance settings.

This tap is rated for through-hole threading applications in high-tensile steel. Its 3-flute spiral point geometry pushes chips forward ahead of the cutting action, keeping flutes clear and reducing the risk of chip packing during the threading cycle. The Series 4122 designation places it within a Guhring product family engineered for general-purpose metric threading. It is well suited for CNC machining centers, drill presses, and tapping heads where coolant-through tooling is not required. The TiN coating extends tool life compared to uncoated high-speed steel in abrasive and harder workpiece materials.

Key Features

• M3 x 0.5 metric coarse thread, 6H class of fit with D3 thread limit
• Powdered metal construction with TiN coating for improved wear resistance
• 3-flute spiral point geometry designed for through-hole threading and forward chip evacuation
• Plug chamfer for standard entry into pre-drilled through holes
• Right-hand thread direction, no coolant-through requirement
• Overall length of 2.205 inches and shank diameter of 0.141 inches for compatibility with standard tap holders

Compatibility

Designed for through-hole threading in high-tensile steel workpieces using standard M3 x 0.5 metric coarse tap holders and collet-style tapping heads. Confirm holder bore accommodates a 0.141-inch shank diameter before installation.

Installation Notes

Installation and use should be performed by qualified machinists familiar with tapping operations and cutting tool safety. Power down or de-energize the machine spindle completely before loading or changing the tap. Secure the tap firmly in an appropriate holder to prevent slippage during the threading cycle. Follow shop-floor speed and feed guidelines for the specific workpiece material and ensure the workpiece is properly fixtured before initiating the cut.
