Hertel K020610AS Straight Flute Tap M33 X 2.00 Plug Hss

Product Description

The HERTEL K020610AS is a straight-flute plug tap designed for cutting Metric Fine internal threads in a machine shop or production environment. Ground from high speed steel with a bright, uncoated finish, it cuts M33 x 2.00 threads with a right-hand helix. The plug chamfer — typically 3 to 5 lead threads — makes it suitable for through-hole tapping and most general-purpose threading operations. With 4 flutes and a D5 thread limit, it holds close tolerances for precision threaded assemblies. Overall length is 5.75 inches, thread length is 2.5625 inches, shank diameter is 1.108 inches, and square size is 0.831 inches. This tap is intended for use by machinists and tool-and-die professionals working to Metric Fine thread standards.

This tap is suited for through-hole or open-ended blind-hole applications in ferrous and non-ferrous metals where Metric Fine M33 x 2.00 internal threads are required. Common use cases include threading hydraulic fittings, fastener repairs, and precision mechanical assemblies that require the finer pitch of the Metric Fine standard versus coarse Metric. It is typically driven by a tapping head, CNC machining center, or manual tap wrench in low-to-medium production runs. Coolant-through capability is not available on this tap.

Key Features

• M33 x 2.00 Metric Fine thread form for close-tolerance internal threading
• Plug chamfer provides a gradual lead-in suitable for through-holes and most blind-hole applications
• 4-flute straight configuration clears chips effectively in short-chipping materials
• High speed steel construction withstands standard tapping speeds without special coatings
• D5 thread limit maintains tight pitch diameter tolerance for precision fits
• Right-hand thread direction compatible with standard tapping equipment and tap holders

Compatibility

Designed as an OEM-style replacement or direct-use tap for machine tapping operations requiring M33 x 2.00 Metric Fine internal threads in standard straight-flute tap holders and tapping heads.

Installation Notes

This tap is installed and driven by a licensed machinist or tool-and-die technician using a compatible tap holder, tapping head, or manual tap wrench sized for the 1.108-inch shank diameter. Ensure the workpiece is securely fixtured and the spindle is properly aligned with the pre-drilled tap drill hole before beginning the threading cycle. Apply an appropriate cutting fluid for the workpiece material to extend tap life and reduce galling. Inspect the tap for chipping or wear before each use; a damaged tap should not be forced into a workpiece.
