Osg 1410106908 Thread Forming Tap M3x0.50 Metric Coarse

Product Description

The OSG 1410106908 is a thread forming tap designed for M3x0.50 Metric Coarse applications, featuring a modified bottoming chamfer with 2 to 2.5 chamfered threads. Built from cobalt high-speed steel and finished with a TiCN coating, this tap generates internal threads by displacing material rather than cutting it, producing stronger thread forms with no chips. It carries a D4 thread limit and is suited for blind hole threading operations. The overall length is 1.9291 inches with a thread length of 0.2441 inches and a tapping depth of 0.6299 inches. This tap is part of the OSG HY-PRO NRT Series 14101 and is intended for use by machinists and toolroom professionals in production or maintenance environments.

This tap is suited for blind hole threading in a range of materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. Its modified bottoming chamfer allows threading close to the bottom of a blind hole, making it a practical choice for tight-tolerance work where full thread depth is required near the hole base. The right-hand thread direction is standard for most threading applications across both production and repair work.

Key Features

• Thread forming design displaces material for stronger threads and eliminates chip evacuation concerns in blind holes
• Cobalt high-speed steel construction provides heat and wear resistance in demanding materials including hardened steel and stainless steel
• TiCN coating reduces friction and extends tool life across a broad range of workpiece materials
• Modified bottoming chamfer with 2 to 2.5 chamfered threads allows threading close to the bottom of blind holes
• D4 thread limit ensures consistent thread fit and tolerance control
• Right-hand thread direction compatible with standard tapping equipment and tap handles

Compatibility

Designed as an OEM-style replacement thread forming tap for M3x0.50 Metric Coarse blind hole threading applications in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Installation Notes

Thread forming taps are typically installed by machinists or tool and die professionals using a tapping machine, CNC machining center, or manual tap handle rated for the torque required by the workpiece material. Ensure the spindle speed and feed rate are appropriate for the tap diameter and material before engaging the tap. Secure the workpiece fully before tapping to prevent movement that could break the tap or damage the thread. Coolant or tapping fluid is recommended to maintain tool life, even though this tap does not feature through-coolant capability.
