Kennametal 4131843 M14x2 Bottoming Hand Tap Hss 6H

Product Description

The KENNAMETAL 4131843 is a straight-flute hand tap designed for cutting M14x2.00 metric coarse internal threads in bottoming applications. Manufactured from high-speed steel with a bright, uncoated finish, it produces clean, accurate threads in cast iron and non-ferrous metals. The bottoming chamfer allows threading close to the bottom of a blind hole where taper or plug taps cannot reach. With four flutes and a 6H class of fit at thread limit D7, the tap delivers consistent dimensional accuracy expected in precision machining and repair work. Overall length is 3.59 inches with a thread length of 1.656 inches.

This tap is suited for manual threading operations in maintenance, repair, and fabrication environments. It is the correct choice when a blind hole must be threaded nearly to its full depth, such as in fixture building, equipment repair, or component rework involving cast iron and non-ferrous workpieces. It is intended for use with a standard tap wrench and cutting fluid appropriate for the workpiece material.

Key Features

• Bottoming chamfer for threading to the bottom of blind holes
• M14x2.00 metric coarse thread profile, 6H class of fit
• Thread limit D7 for consistent fit and tolerance control
• High-speed steel construction for durability across cast iron and non-ferrous materials
• Bright uncoated finish — compatible with a wide range of cutting fluids
• Four straight flutes for efficient chip clearance in hand tapping

Compatibility

Rated for use in cast iron and non-ferrous metal workpieces requiring M14x2.00 metric coarse internal threads at a 6H fit tolerance.

Installation Notes

This tap is installed by a machinist or maintenance technician using a standard tap wrench. Always apply an appropriate cutting fluid for the workpiece material before and during tapping to reduce friction and extend tool life. Ensure the tap is started perpendicular to the workpiece surface to avoid thread misalignment or tap breakage. Remove chips frequently during hand tapping, especially in blind holes, to prevent chip packing and binding.
