Hertel K008147AS Straight Flute Tap 6-32 Unc Hss

Product Description

The HERTEL K008147AS is a straight flute tap designed to cut 6-32 UNC internal threads in through-hole and blind-hole applications. Built from high-speed steel with a bright, uncoated finish, this tap delivers consistent thread form in steel, aluminum, and similar materials where a standard HSS tool is appropriate. The taper chamfer eases entry and distributes cutting load across the first several threads. At 2 inches overall length with a right-hand thread direction and H2 thread limit, the K008147AS suits general-purpose tapping in production and maintenance environments. Three flutes provide adequate chip clearance for moderate cutting depths.

This tap is intended for use on standard #6-32 UNC fastener applications common in light fabrication, machine assembly, electrical enclosure work, and general maintenance repair operations. The taper chamfer makes it particularly well-suited for through-hole tapping where the tool can pass fully through the workpiece, allowing chips to exit freely. It is appropriate for manual tapping with a tap wrench as well as low-speed machine tapping operations where feed is carefully controlled.

Key Features

• 6-32 UNC thread form for standard inch-series fastener applications
• Taper chamfer distributes cutting load for easier thread entry
• High-speed steel construction provides hardness and wear resistance for general-purpose materials
• Bright, uncoated finish suitable for use with cutting fluids
• H2 thread limit maintains 3B class of fit tolerance for standard thread engagement
• Right-hand thread direction, compatible with conventional tapping equipment

Compatibility

Designed as a standard replacement or general-purpose straight flute tap for 6-32 UNC threading operations in manual or machine tapping setups requiring a 3B class of fit.

Installation Notes

Tapping should be performed by a qualified machinist or maintenance technician familiar with thread cutting procedures. Always secure the workpiece firmly and use an appropriate cutting fluid or tapping compound to reduce heat and extend tool life. For machine tapping, verify spindle speed and feed rate are set for the workpiece material before engaging the tap. Inspect the tap for chipping or wear before each use and replace if the cutting edges are damaged to avoid thread damage or tap breakage.
