Osg 2888500 Spiral Point Tap M10x1.50 Metric Coarse 6H Hss

Product Description

The OSG 2888500 is a spiral point tap designed for cutting internal metric coarse threads in a range of common workpiece materials. It produces an M10x1.50 thread profile with a 6H class of fit, making it suitable for applications that require standard tolerance threading. The plug chamfer provides a gradual thread lead-in, distributing cutting forces across several lead threads for controlled tap engagement. Manufactured from high-speed steel with a bright finish, the 2888500 is a straightforward, general-purpose tapping solution for machine shops, maintenance facilities, and fabrication environments. The overall length is 74.6 mm, with a thread length of 1.25 inches.

This tap is intended for use in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. The plug chamfer style makes it well suited for through-hole tapping operations where chip flow ahead of the tap is acceptable. It is commonly used in CNC machining centers, drill presses, and tapping machines where a right-hand thread is required. Coolant-through capability is not included in this design, so external flood or mist coolant is recommended when tapping steel at production rates.

Installation Notes

Tapping operations should be performed by a qualified machinist following shop safety procedures. Ensure the workpiece is securely fixtured and the tap is properly aligned with the pre-drilled pilot hole before engagement. Apply an appropriate cutting fluid or tapping compound for the workpiece material to reduce heat and extend tool life. Inspect the tap for wear or damage before each use and replace if cutting edges show signs of chipping or dullness.
