Osg 1410101601 Thread Forming Tap M3x0.50 Metric Coarse

Product Description

The OSG 1410101601 is a thread forming tap in the HY-PRO NRT series, designed for producing M3x0.50 metric coarse internal threads without cutting chips. Made from cobalt high-speed steel with a steam oxide coating, this tap uses cold-forming action to displace material rather than remove it, resulting in stronger threads and longer tool life. The modified bottoming chamfer with 2 to 2.5 chamfered threads allows threading close to the bottom of a blind hole. It is sized for production and maintenance machining environments where consistent thread quality is required in tough materials.

This tap is suited for blind hole threading applications in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The cobalt construction handles the heat generated in harder ferrous materials, and the steam oxide finish improves lubricity and corrosion resistance during use. It is a right-hand tap intended for CNC machining centers, drill presses, and tapping heads in light manufacturing, toolroom, and general metalworking applications. Its compact overall length of 1.929 inches makes it a practical choice for confined setups.

Key Features

• Thread forming design displaces material rather than cutting chips, producing stronger threads with no chip evacuation required
• Cobalt high-speed steel construction provides heat and wear resistance in hardened and stainless steel applications
• Steam oxide coating improves lubricity and reduces galling during tapping
• Modified bottoming chamfer with 2 to 2.5 chamfered threads enables threading near the bottom of blind holes
• Class of fit 4H with D3 thread limit for consistent, precision thread production
• Compatible with alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces

Compatibility

Designed for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. Material application codes P and N confirm suitability across a range of ferrous and non-ferrous workpiece materials. Part of OSG HY-PRO NRT Series 14101.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with tapping speeds, feeds, and lubrication requirements for cold-form tapping. Ensure the spindle and workpiece are properly secured before operation, and use a compatible tapping fluid or cutting oil appropriate for the workpiece material. Power down and de-energize all machine tooling before changing or inspecting the tap. For blind hole applications, verify tapping depth does not exceed the rated tapping depth to avoid tool breakage or thread distortion.
