Frequently Asked Questions
What is an OSG spiral flute tap used for?
An OSG spiral flute tap is used for threading blind holes in materials such as steel, stainless steel, and aluminum. The spiral flute design pulls chips upward and out of the hole, preventing chip clogging and enabling cleaner threads in deep or blind-hole applications.
What are the specifications of the OSG 3/8-16 UNC spiral flute tap?
This OSG tap has a 3/8-16 UNC thread size, 3 flutes, and a modified bottoming chamfer. It is rated H7 / 2B-3B tolerance, meaning it produces threads within a precise fit range. The manufacturer part number is 2942100.
Where to buy OSG taps in worldwide?
3G Electric supplies OSG taps worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine OSG cutting tools and can deliver to your facility regardless of location.
How to select the right spiral flute tap for blind holes?
For blind holes, choose a spiral flute tap with a modified bottoming chamfer, like this OSG 3/8-16 UNC tap, to thread close to the hole bottom. Ensure the tap's flute count and helix angle match the material; 3 flutes work well for general-purpose threading in steel and aluminum.
