Hertel K020249AS M10x1.50 Metric Coarse Straight Flute Tap

Product Description

The HERTEL K020249AS is a straight flute plug tap designed for cutting M10x1.50 metric coarse internal threads in through-holes and blind holes where chip evacuation is manageable. Manufactured from high-speed steel with a bright uncoated finish, this tap delivers reliable thread-cutting performance in a range of ferrous and non-ferrous materials. The plug chamfer provides a gradual lead-in of several threads, distributing cutting load across the entry threads for controlled thread engagement. At 2-15/16 inches overall length with a 1-1/4 inch thread length and a 0.381 inch shank diameter, this tap fits standard tap holders and chucks used in manual and machine tapping setups.

This tap is suited for production and maintenance tapping operations in metalworking environments, including machine shops, maintenance departments, and fabrication facilities. The straight flute geometry performs best in short-chipping materials such as cast iron, brass, aluminum, and certain steels. The D3 thread limit indicates a tolerance class appropriate for general-purpose metric threaded assemblies where moderate fit and clearance are acceptable. Machinists, tool and die makers, and maintenance technicians typically deploy this tap for M10 threaded hole creation using a tap wrench, drill press, or CNC machining center.

Key Features

• M10x1.50 metric coarse thread form for standard metric fastener compatibility
• Plug chamfer with gradual lead-in distributes cutting load for controlled entry
• Straight flute geometry suited to short-chipping materials
• High-speed steel construction provides toughness in general-purpose tapping applications
• D3 thread limit for general-purpose metric fit tolerances
• Bright uncoated finish with no coolant-through requirement for simplified setup

Compatibility

Designed as a general-purpose straight flute tap for M10x1.50 metric coarse threaded holes; compatible with standard tap holders, T-handle tap wrenches, and machine tap chucks accepting a 0.381 inch shank diameter.

Installation Notes

Machinists and maintenance technicians should ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for M10x1.50 before use. Power down and de-energize any machine tool before mounting or removing the tap from a chuck or holder. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Straight flute taps should not be used as a substitute for spiral-point or spiral-flute taps in deep blind-hole applications where chip packing is a concern.
