Hertel K1001191828 Spiral Point Tap M2.2x0.45 Hss

Product Description

The HERTEL K1001191828 is a spiral point tap designed for cutting internal threads in through-hole applications. Built from high speed steel, this plug-chamfer tap drives chips forward ahead of the cutting zone, making it well suited for production tapping in through holes rather than blind bores. The thread profile is M2.2 x 0.45, Metric Coarse, with a right-hand thread direction and a D3 thread limit for close tolerance control. Two flutes provide adequate chip clearance at this small diameter, and the plug chamfer eases entry and distributes cutting load across multiple leading threads.

This tap is used in metalworking and machining applications where M2.2 Metric Coarse internal threads are required in through holes. Typical scenarios include tapping small fastener holes in instrument housings, electronic assemblies, precision fixtures, and light mechanical components. It is installed by machinists and toolroom technicians using a tapping head, CNC machine, or hand tap wrench depending on the production environment. Coolant-through capability is not supported on this tap, so external lubrication or cutting fluid should be applied at the workpiece.

Key Features

• M2.2 x 0.45 Metric Coarse thread form for small-diameter through-hole tapping
• Spiral point geometry drives chips forward, reducing recutting in through holes
• High speed steel construction provides good wear resistance in a range of workpiece materials
• Plug chamfer distributes cutting load across several leading threads for controlled entry
• D3 thread limit for consistent tolerance control in close-fit thread applications
• Right-hand thread direction; 2-flute design suited to the small diameter

Compatibility

Designed as an OEM-style replacement or direct-use spiral point tap for M2.2 x 0.45 Metric Coarse through-hole tapping operations in standard machining and production environments.

Installation Notes

This tap is installed by qualified machinists or toolroom technicians using appropriate tapping equipment. Before tapping, ensure the pilot hole is drilled to the correct M2.2 x 0.45 Metric Coarse tap drill size and that the workpiece is securely fixtured. Apply a suitable cutting fluid or tapping compound to the workpiece before and during the tapping operation. Do not force the tap if resistance is felt; back off to break and clear chips before continuing.
