Osg 1006100400 Straight Flute Tap M5x0.80 Metric Coarse

Product Description

The OSG 1006100400 is a straight flute machine tap designed for cutting internal M5x0.80 metric coarse threads in a range of metals. Built from solid carbide with a bright uncoated finish, it delivers the rigidity and edge retention required for precision tapping in production and repair environments. The plug chamfer provides a gradual thread lead-in, making it well suited for through-hole applications. With 4 flutes and a 6H class of fit tolerance, this tap produces threads to metric standard specifications. Overall length is 2.375 inches with a thread length of 0.875 inches. It is used by machinists and toolroom technicians working with CNC machining centers, drill presses, or tapping heads.

The 1006100400 is rated for use in aluminum, cast aluminum, cast iron, cobalt chrome, and copper alloy workpieces. Its solid carbide construction handles the abrasive properties of cast materials and the gummy characteristics of aluminum without the flex associated with high-speed steel tooling. The D4 thread limit designation ensures the tapped hole stays within the upper range of 6H tolerance, accounting for slight material springback. This tap is part of OSG Series 10061 and is packaged as a single unit.

Key Features

• Solid carbide construction for superior rigidity and wear resistance versus HSS
• Plug chamfer for gradual thread engagement in through-hole tapping
• 6H class of fit with D4 thread limit for precise metric thread tolerance
• 4 straight flutes with no coolant-through requirement
• Right-hand thread direction, M5x0.80 metric coarse pitch
• Bright uncoated finish compatible with a wide range of cutting fluids

Compatibility

Rated for use in aluminum, cast aluminum, cast iron, cobalt chrome, and copper alloy. Suitable for machine tapping operations in CNC and manual tapping setups requiring M5x0.80 metric coarse threads to 6H tolerance.

Installation Notes

This tap is installed by machinists and toolroom technicians. Before use, secure the workpiece and verify the pilot hole diameter matches the M5x0.80 tap drill specification. Use an appropriate cutting fluid or tapping compound for the workpiece material to reduce heat and extend tool life. Solid carbide taps are brittle — avoid side loading, misalignment, or hand-feeding without a guide; use a rigid tapping setup or floating tap holder wherever possible.
