OSG Coolant-Through Straight-Flute Machine Taps for Aluminum.

Frequently Asked Questions

What is an OSG straight flute tap used for?

An OSG straight flute tap is used for threading holes in aluminum and non-ferrous materials. The 7/16"-20 UNF bottoming chamfer design allows threading to the bottom of blind holes, while coolant-through flutes improve chip evacuation and lubrication in production machining.

What are the specifications of the OSG 1005301208 tap?

The OSG 1005301208 is a straight flute tap with 7/16"-20 UNF thread, H3 / 2B-3B tolerance, 4 flutes, and a bottoming chamfer. It is designed for coolant-through operation in aluminum. The H3 ground thread limit ensures precise fit for 2B-3B class threads.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine OSG cutting tools like the 1005301208 straight flute tap for aluminum threading. Contact us for pricing and delivery to your location.

How to select the right tap for aluminum threading?

For aluminum, choose a tap with polished flutes and coolant-through capability to reduce built-up edge. The OSG straight flute tap with H3 / 2B-3B tolerance and bottoming chamfer is ideal for blind holes. Match thread size (7/16"-20 UNF) and ensure proper cutting speed and lubrication.
