Osg 1635060148 Thread Forming Tap M6x1.00 Metric 6H Plug

Product Description

The OSG 1635060148 is a thread forming tap designed for M6x1.00 metric threading in through-hole applications. Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger, chip-free threads suited for production environments. This tap is manufactured from cobalt high speed steel with a V-coating finish, delivering thermal and wear resistance during high-speed tapping cycles. It carries a 6H class of fit and D8 thread limit, making it appropriate for close-tolerance metric threading. Licensed machinists and tool-and-die technicians typically specify this tap for demanding material groups where thread integrity is critical.

The OSG 1635060148 is rated for through-hole threading across a broad range of materials, including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium. It is part of the OSG EXOPRO XPF Series 16350, a line engineered for aggressive material applications in both job-shop and production settings. The plug chamfer with 4 to 4.5 thread chamfer length makes it well suited for through-hole entries where starting alignment and thread lead-in are straightforward.

Key Features

• Thread forming (chipless) design produces stronger threads and eliminates chip-clearing concerns in through-hole work
• Cobalt high speed steel construction with V-coating for extended tool life in hard and abrasive materials
• 6H class of fit and D8 thread limit for close-tolerance metric thread production
• Plug chamfer (4 to 4.5P) for efficient through-hole thread starting
• Right-hand thread direction, compatible with standard tapping equipment and CNC machining centers
• Rated for a wide material application range including stainless steel, titanium, and high-nickel alloys

Compatibility

Designed for M6x1.00 metric through-hole threading applications across aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium workpieces, as specified by material application codes P, M, N, and H.

Installation Notes

Thread forming taps require a properly sized forming tap drill hole, which is larger than a standard cut tap drill size for the same thread — consult an M6 thread forming tap drill chart before setup. Use an appropriate tapping fluid or cutting oil matched to the workpiece material, particularly for stainless steel, titanium, and high-nickel alloys. Ensure the spindle speed and feed rate on CNC or manual tapping equipment are set for thread forming, not thread cutting. Secure the workpiece fully before operation and verify tapping depth does not exceed the rated tapping depth of 30.00 mm.
