Kennametal 5946065 Thread Forming Tap 1/2-13 Bottoming

Product Description

The KENNAMETAL 5946065 is a 1/2-13 UNC bottoming thread forming tap manufactured from Powdered Metal High Speed Steel (HSS-E-PM) and coated with AlCrTiN for extended tool life in demanding applications. With an overall length of 4.3307 inches (110 mm) and a thread length of 0.7874 inches (20 mm), this tap is engineered for cold-forming internal threads without chip generation. The bottoming chamfer of 1.5 to 2 threads allows threading close to the bottom of blind holes. It carries a thread limit designation of H5 and is part of the KENNAMETAL Beyond trade line. Machinists and toolroom professionals working in ferrous and some non-ferrous materials will find this tap suited to precision blind-hole threading operations.

This tap is designed for blind hole threading in materials coded P and M, which covers carbon steels, alloy steels, and stainless steels. With a tapping depth of 1.8504 inches (47 mm) and a right-hand thread direction, it fits standard CNC machining center and tapping head setups. The six oil groove design supports lubrication during forming. Material grade KSP27 indicates a fine-grain powdered metal substrate optimized for toughness and edge retention at elevated cutting temperatures. This tap is commonly used in production machining, job shop environments, and maintenance toolrooms where chip-free thread forming is preferred over cutting taps.

Key Features

Compatibility

Designed for blind hole threading in P and M material application codes, covering carbon steels, alloy steels, and stainless steels. Intended for use in standard tapping heads, CNC machining centers, and manual tapping setups accepting a 0.3670-inch shank diameter with a 0.2750-inch square drive.

Installation Notes

Thread forming taps require adequate lubrication or cutting fluid matched to the workpiece material — consult the fluid manufacturer for recommendations for steel grades. Ensure the machine spindle and tap holder are properly aligned before engagement to avoid thread distortion or tap breakage. Power down and lock out all equipment before changing tooling. Follow the machine tool manufacturer torque and speed specifications for the workpiece material and hole diameter.
