Osg 1410103200 Thread Forming Tap M5x0.80 Cobalt

Product Description

The OSG 1410103200 is a thread forming tap designed for cold-forming internal threads without cutting chips, reducing the risk of chip contamination in blind holes. Built from cobalt high-speed steel with a bright finish, this tap handles M5x0.80 metric coarse threads with a modified bottoming chamfer of 2 to 2.5 chamfered threads. The overall length is 2.374 inches (60.30 mm) with a tapping depth of 0.874 inches (22.20 mm). It carries a Class of Fit 4H with a D4 thread limit, making it suitable for precision threading applications across a range of metalworking environments. Licensed machinists and tool-and-die professionals are the primary users of this tap.

This tap is intended for blind hole threading in a variety of metal substrates including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The thread forming process work-hardens the thread walls, producing stronger threads compared to cut tapping in many materials. Its modified bottoming chamfer allows threading close to the bottom of a blind hole while maintaining thread quality. It is well suited for CNC machining centers and manual tapping operations where chip evacuation is a concern.

Key Features

• M5x0.80 metric coarse thread profile with right-hand thread direction
• Modified bottoming chamfer (2 to 2.5 chamfered threads) for threading near the base of blind holes
• Cobalt construction for improved heat and wear resistance in tough alloys and hardened steel
• Bright finish suitable for use with standard tapping fluids and coolants
• Class of Fit 4H with D4 thread limit for consistent dimensional accuracy
• No coolant-through design; compatible with external flood or brush-applied cutting fluid

Compatibility

Rated for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces. Material application codes P and N apply. Part of the OSG HY-PRO NRT Series 14101.

Installation Notes

Thread forming taps require adequate lubrication at the tap-workpiece interface; use a tapping fluid rated for the specific workpiece material. Ensure the pilot hole diameter is correct for form tapping, as it differs from cut tap drill charts. Secure the workpiece firmly and align the tap perpendicular to the hole surface before engaging. Always de-energize and lock out any CNC or power tapping equipment before changing or inspecting taps.
