Osg 2692505 Spiral Point Tap M14x1.50 Metric Fine Tin Hss

Product Description

The OSG 2692505 is a spiral point tap designed for cutting M14x1.50 metric fine internal threads in a wide range of ferrous and non-ferrous materials. Built from vanadium high-speed steel (HSS-E) and finished with a titanium nitride (TiN) coating, this tap delivers extended tool life and reduced friction during threading operations. It features a plug chamfer, a 3-flute spiral point geometry that pushes chips ahead of the cut, and coolant-through capability for improved chip evacuation and heat control in deep or high-production threading applications. A right-hand cut and 6H class of fit make it suitable for standard metric fine thread tolerance requirements.

This tap is suited for threading aluminum, cast iron, low-, medium-, and high-carbon steel, alloy steel, die steel, stainless steel, and hardened steel. The plug chamfer style means it is typically used in through-hole applications where a partial thread lead-in is acceptable. It is commonly specified in CNC machining centers, drill presses, and tapping machines in job shop, production, and maintenance environments. Licensed machinists and toolroom technicians are the primary installers and operators of this tool.

Key Features

• Spiral point (gun tap) geometry pushes chips forward, reducing chip packing in through-hole applications
• TiN coating improves surface hardness and lubricity for longer tool life and cleaner thread finish
• Vanadium HSS-E construction for toughness in difficult-to-machine materials including stainless and alloy steel
• Coolant-through design supports high-speed or deep-hole tapping with effective chip and heat management
• 6H class of fit meets standard metric fine thread tolerance for general engineering applications
• Right-hand thread direction; non-interrupted, non-oversize thread form

Compatibility

Designed as an OEM-style threading tool for M14x1.50 metric fine through-hole applications across machining setups that accept straight-shank taps with a 0.4290-inch shank diameter.

Installation Notes

This tap is installed and operated by qualified machinists or toolroom technicians using a compatible tap holder, tapping head, or CNC rigid tapping cycle. Always ensure the spindle speed and feed rate match the tool manufacturer guidelines for the workpiece material before beginning the threading cycle. Confirm the coolant-through circuit is active when using this feature to prevent chip packing and tap breakage. Secure the workpiece firmly and verify hole diameter and depth are correct for the M14x1.50 thread specification before engaging the tap.
