Titan Usa TT91094 Spiral Point Tap 5/8-11 Unc Hss Plug

Product Description

The TITAN USA TT91094 is a spiral point plug tap designed for through-hole threading in general-purpose machining applications. It cuts a 5/8-11 UNC right-hand thread using three flutes and a plug chamfer geometry that pushes chips forward ahead of the tap, keeping the flutes clear during the cut. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap handles a wide range of workpiece materials including mild steel, aluminum, and plastics. The H5 thread limit provides consistent tolerance control for 2B and 3B class-of-fit threads. Overall length is 3.8125 inches with a thread length of 1.8125 inches and a shank diameter of 0.480 inches.

This tap is suited for job shop, maintenance, and production environments where through-hole tapping in standard UNC thread sizes is a routine operation. The spiral point design makes it particularly effective in CNC tapping cycles and hand-tap applications where chip evacuation is critical to thread quality. It is used by machinists, tool-and-die makers, and maintenance technicians working in both light and heavy manufacturing settings. The plug chamfer provides 3 to 5 leading threads of chamfer length, offering a good balance of starting ease and thread engagement.

Key Features

• 5/8-11 UNC thread form with right-hand cutting direction
• Spiral point geometry pushes chips forward, ideal for through-hole applications
• H5 thread limit for consistent 2B/3B class-of-fit tolerance control
• High-speed steel construction for general-purpose material compatibility
• Bright/uncoated finish suitable for use with standard cutting fluids
• 3 flutes with plug chamfer for balanced chip load and easy starting

Compatibility

Designed as a general-purpose spiral point plug tap for through-hole threading operations requiring a 5/8-11 UNC right-hand thread in 2B or 3B class-of-fit applications. No specific machine or system compatibility was stated in the product data.

Installation Notes

Installation is performed by machinists using a tap wrench, tapping head, or CNC rigid tapping cycle. Ensure the workpiece is securely fixtured and the tap is properly aligned to the drilled hole before engagement. Apply an appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Do not reverse the tap under load without first relieving chip pressure to avoid breakage.
