Osg 1006101400 Straight Flute Tap M5x0.80 Metric Coarse

Product Description

The OSG 1006101400 is a solid carbide straight flute tap designed for cutting M5x0.80 metric coarse internal threads in machine tapping applications. With a bottoming chamfer, this tap produces threads to the full depth of a blind hole, making it the right choice when thread engagement must extend close to the bottom. The 6H class of fit and D4 thread limit ensure accurate, tolerance-controlled threads. At 2.5 inches overall length with a 1-inch thread length, this tap is sized for precision work in compact part geometries. A licensed machinist or tooling specialist typically selects and installs this tool in CNC machining centers or tapping machines.

This tap is suited for production and maintenance machining environments where metric threaded holes are required in a range of materials. The Series 10061 solid carbide construction gives it rigidity and wear resistance compared to high-speed steel alternatives. Listed material applications include aluminum, cast aluminum, cast iron, cobalt chrome, and copper alloy. The straight flute geometry works well in through-hole and short blind-hole configurations where chip evacuation is managed by the cutting action. This tool is sold individually.

Key Features

• M5x0.80 metric coarse thread form, 6H class of fit with D4 thread limit for consistent tolerance control
• Bottoming chamfer for threading to the full depth of blind holes
• Solid carbide construction for rigidity and extended tool life in abrasive materials
• 4 straight flutes suitable for aluminum, cast iron, cobalt chrome, and copper alloy
• Bright/uncoated finish — no coating buildup that could affect thread tolerance in close-fit applications
• Right-hand thread direction, no coolant-through requirement

Compatibility

Designed for machine tapping applications requiring M5x0.80 metric coarse internal threads. Rated for use in aluminum, cast aluminum, cast iron, cobalt chrome, and copper alloy workpiece materials per OSG Series 10061 specifications.

Installation Notes

This tap is intended for use by machinists in CNC machining centers, drill presses, or dedicated tapping machines — not for hand tapping. Secure the tap in an appropriate tap holder or collet sized for the 0.2550-inch shank diameter before operation. Ensure the spindle is stopped and the machine is in a safe state before loading or changing tooling. Follow shop speeds and feeds data for the specific workpiece material; bottoming taps require the pre-drilled hole to be at the correct depth before the chamfer reaches full thread engagement.
