Osg 2888301 Spiral Point Tap M6x1.00 Metric Coarse 6H

Product Description

The OSG 2888301 is a spiral point tap designed for cutting internal metric coarse threads in a range of ferrous and non-ferrous materials. The plug chamfer style provides a gradual thread lead-in, making it well suited for through-hole tapping applications where chip ejection is a priority. Manufactured from high-speed steel with a steam oxide coating, this tap offers improved lubricity and corrosion resistance during service. The 6H class of fit produces threads within standard metric tolerance, and the right-hand cutting direction makes it compatible with conventional tapping setups. Machinists and maintenance technicians rely on this style of tap for production and repair threading work.

This tap is intended for use in through-hole tapping operations on aluminum, cast aluminum, low-carbon steel, and medium-carbon steel workpieces. It is a practical choice for machine shop production, MRO maintenance threading, and fixture fabrication. The M6x1.00 thread size is one of the most common metric fastener sizes encountered in industrial and mechanical assemblies, making this tap a frequently used item in both manual and CNC tapping operations.

Key Features

• Spiral point geometry pushes chips forward through the hole, reducing clogging during through-hole tapping
• Plug chamfer provides a gradual lead-in for smooth thread engagement
• High-speed steel construction provides toughness and wear resistance across supported material applications
• Steam oxide coating improves surface lubricity and reduces galling on startup
• 6H class of fit meets standard metric thread tolerance for general mechanical assemblies
• Right-hand thread direction compatible with standard tapping heads, drill presses, and CNC machines

Compatibility

Designed for through-hole tapping of M6x1.00 metric coarse threads in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. Coolant-through is not supported on this tap.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with tapping operations. Always secure the workpiece and ensure the spindle is aligned perpendicular to the tapped surface before beginning the operation. Apply an appropriate cutting fluid for the material being tapped. For manual tapping, use a properly sized tap wrench and advance with consistent pressure, backing off periodically to break chips.
