Value Collection JY4995205 Straight Flute Tap M30x1.50

Product Description

The VALUE COLLECTION JY4995205 is a straight flute tap designed to cut M30x1.50 Metric Fine internal threads in pre-drilled holes. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread-cutting performance in ferrous and non-ferrous metals. It features 4 straight flutes, a plug chamfer for starting the cut in through-holes or sufficiently deep blind holes, and a D7 thread limit for consistent tolerance control. The overall length is 4 inches with a thread length of 2.5625 inches. Machinists, toolmakers, and maintenance technicians use this tap in manual tapping operations and machine tap holders alike.

This tap is suited for threading M30x1.50 Metric Fine holes in general machining, maintenance, repair, and fabrication environments. The plug chamfer style makes it appropriate for through-hole applications and blind holes with adequate thread runout. Right-hand thread direction aligns with standard fastener conventions. This tap does not support coolant-through delivery, so external cutting fluid or tapping compound should be applied during use to extend tool life and improve thread quality in tougher materials.

Key Features

• M30x1.50 Metric Fine thread form for fine-pitch internal threading
• 4 straight flutes for chip clearance in through-hole and open blind-hole applications
• Plug chamfer — 3 to 5 leading threads — for easy thread entry and alignment
• High-speed steel construction provides toughness across a broad range of workpiece materials
• D7 thread limit for precise tolerance control on threaded connections
• Bright, uncoated finish — compatible with a wide range of cutting fluids without coating interaction

Compatibility

Designed for use in standard tap holders, T-handle wrenches, and machine tapping chucks that accept taps with the shank dimensions corresponding to an M30 plug tap. Verify shank diameter and square drive size against your tap holder specifications before use.

Installation Notes

This tap is installed and operated by machinists and toolroom technicians familiar with threading operations. Always ensure the workpiece is securely fixtured and the tap is properly aligned with the pre-drilled pilot hole before beginning the threading operation. Apply cutting fluid or tapping compound throughout the operation to reduce heat and tool wear. When reversing or backing out the tap, do so carefully to avoid breaking the tool, particularly in harder materials or near the bottom of blind holes.
