Hertel K008149AS 6-32 Unc Straight Flute Bottoming Tap Hss

Product Description

The HERTEL K008149AS is a straight flute bottoming tap designed to cut internal threads in through-holes and blind holes where threads must extend close to the bottom. Manufactured from high-speed steel with a bright/uncoated finish, this tap cuts 6-32 UNC right-hand threads to a 3B class of fit with an H2 thread limit. The three-flute straight design channels chips back out of the hole and suits use in most general-purpose threading operations. At 2 inches overall length, it fits standard tap handles and machine setups used by machinists, maintenance technicians, and tool-and-die professionals.

This tap is suited for threading operations in ferrous and non-ferrous materials where a bottoming chamfer is required to produce full threads at the base of a blind hole. The 6-32 UNC thread form is common in electronics enclosures, instrument panels, light-duty fastener assemblies, and precision mechanical components. The H2 thread limit provides close tolerance control and works well with standard 6-32 UNC fasteners in production and repair environments alike.

Key Features

• Bottoming chamfer allows full threads to within 1-2 pitches of a blind hole bottom
• High-speed steel construction provides toughness and wear resistance across general threading applications
• Bright/uncoated finish suited for use with cutting fluids in a wide range of base materials
• 3B class of fit meets standard tolerance requirements for general-purpose threaded assemblies
• H2 thread limit ensures controlled pitch diameter for consistent fastener engagement
• Right-hand thread direction compatible with standard tap handles and tapping heads

Compatibility

Designed as an OEM-style replacement or direct-use tap for any application requiring a 6-32 UNC bottoming tap with a 3-flute straight flute geometry in high-speed steel.

Installation Notes

This tap is installed by licensed machinists or maintenance technicians using a standard tap handle or tapping attachment. Always use appropriate cutting fluid for the material being tapped and ensure the workpiece is securely fixtured before beginning the threading operation. Back the tap out periodically to clear chips and reduce the risk of tap breakage. Do not force the tap past resistance, particularly near the bottom of a blind hole.
