Hertel K025492AS Straight Flute Tap M20 X 2.00 Plug Hss

Product Description

The HERTEL K025492AS is a straight-flute plug tap ground to Metric Fine thread standards, designed for cutting M20 x 2.00 internal threads in through-holes and shallow blind applications. Manufactured from High Speed Steel (HSS) with a bright, uncoated finish, this tap delivers consistent thread form on a wide range of ferrous and non-ferrous workpiece materials. Four straight flutes promote chip evacuation in shorter-chipping materials, while the plug chamfer — typically 3 to 5 threads — provides a gradual cutting action that reduces entry force. The D6 thread limit holds tolerance for general-purpose metric threading applications in production or maintenance environments.

This tap is suited for machine tapping operations on CNC machining centers, knee mills, and drill presses equipped with a tapping head or rigid tapping cycle. Its straight-flute geometry is best applied to through-holes or shallow blind holes where chips can fall clear of the cutting zone. The plug chamfer makes it a practical choice as a starter or all-purpose tap in M20 x 2.00 Metric Fine threading jobs across industrial maintenance, toolroom, and light manufacturing settings.

Key Features

• M20 x 2.00 Metric Fine thread form for precision threaded assemblies requiring finer pitch than standard metric
• 4 straight flutes for chip clearance in short-chipping and through-hole applications
• Plug chamfer (D6 thread limit) for general-purpose threading with gradual cutting entry
• High Speed Steel construction provides wear resistance across a range of workpiece materials
• Bright, uncoated finish — compatible with cutting fluids and coolants suited to HSS tooling
• Right-hand thread direction for standard tapping operations

Compatibility

Designed as an OEM-style replacement or direct tooling selection for any application requiring a Metric Fine M20 x 2.00 straight-flute plug tap with a D6 thread limit and HSS construction.

Installation Notes

Installation of this tap should be performed by a qualified machinist or toolroom technician. Secure the workpiece firmly before tapping and ensure the spindle or tapping head is properly aligned to the pre-drilled pilot hole to prevent tap breakage. Apply an appropriate cutting fluid or tapping compound for the workpiece material before and during the tapping cycle. Never reverse a broken tap fragment with force — consult proper tap extraction procedures to avoid damaging the workpiece thread.
