Osg 2833608 Spiral Point Tap 3/4-10 Unc Ticn Hss-e

Product Description

The OSG 2833608 is a spiral point plug tap designed for threading through-holes in a wide range of ferrous and non-ferrous materials. Manufactured from High-Speed Steel-E (HSS-E) with added vanadium for improved wear resistance, the tap carries a TiCN (Titanium Carbonitride) coating that reduces friction and extends tool life in demanding cutting conditions. The plug chamfer style distributes cutting load across the lead threads for smooth entry and consistent thread formation. It cuts a 3/4-10 UNC right-hand thread to an H3 tolerance limit, making it suitable for general-purpose production and maintenance threading work. Licensed tradespeople and machining professionals are the primary installers of this tool.

This tap is well suited for through-hole threading operations on production lines, maintenance repair benches, and fabrication shops. The 3-flute spiral point geometry pushes chips forward ahead of the tap, keeping the flutes clear and allowing higher feed rates in through-hole applications. Compatible material applications include aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, cast iron, and hardened steel, making it a versatile option across industries including structural fabrication, tooling, and general machining.

Key Features

• 3/4-10 UNC thread form, right-hand cut, H3 tolerance limit for consistent fit
• HSS-E (vanadium High-Speed Steel) construction for enhanced wear resistance over standard HSS
• TiCN coating reduces friction, improves surface hardness, and extends tool life
• Spiral point geometry pushes chips forward — optimized for through-hole threading
• Plug chamfer provides gradual cutting load distribution for smooth thread entry
• 3-flute design balances chip clearance and cutting stability in a range of materials

Compatibility

Rated for use in aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, and cast iron. Not rated for interrupted thread applications.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench, tapping head, or CNC rigid tapping cycle. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for 3/4-10 UNC before tapping. Apply appropriate cutting fluid for the material being threaded to protect the coating and extend tap life. Coolant-through is not supported on this tool.
