Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is designed for through-hole threading in production environments. Its spiral-point geometry pushes chips forward, preventing chip congestion and enabling faster, cleaner threading in materials like steel, aluminum, and cast iron across machining, automotive, and general manufacturing applications.

What are the specifications of the OSG 2812508 tap?

The OSG 2812508 is a #6-32 UNC spiral point tap with an H4 / 2B-3B tolerance class, 2 flutes, and a plug chamfer. It is designed for general-purpose through-hole threading and is manufactured by OSG, a leading cutting tool brand. 3G Electric supplies this tap globally.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps, including the 2812508 spiral point tap, to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other OSG cutting tools across our 14 industrial departments.

How to select the right spiral point tap for through holes?

Select a spiral point tap based on thread size, pitch, material, and hole type. For through holes, spiral point taps push chips ahead, reducing breakage. Match the tap tolerance (e.g., H4) to your required thread class (2B-3B). OSG taps like the 2812508 offer reliable performance in production threading.
