Value Collection JY4993754 M16x1.50 Straight Flute Tap

Product Description

The VALUE COLLECTION JY4993754 is a straight flute plug tap designed for cutting M16x1.50 metric fine internal threads in through-holes and blind holes where chip evacuation is manageable. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tap offers a solid balance of hardness and toughness suitable for general-purpose threading operations. It features 4 flutes and a plug chamfer, which distributes cutting load across several lead threads for controlled thread entry. The overall length is 3.8125 inches with a thread length of 1.8125 inches, giving machinists and toolroom technicians a compact, balanced tool for bench or machine use.

This tap is suited for threading M16x1.50 metric fine holes in ferrous and non-ferrous metals including mild steel, aluminum, and cast iron in light-to-medium production or maintenance applications. The straight flute design performs best in through-hole applications or short blind holes where chips can be cleared with proper lubrication and reversal technique. It is a common choice for automotive, industrial maintenance, and general fabrication work where metric fine threads are specified.

Key Features

• M16x1.50 metric fine thread form for precise, fine-pitch internal threading
• 4-flute straight configuration for balanced cutting and rigidity
• Plug chamfer (3-5 lead threads) allows gradual thread engagement and reduced entry force
• High-speed steel construction provides wear resistance across a wide range of workpiece materials
• Bright/uncoated finish suitable for use with cutting oils and standard tapping fluids
• Right-hand thread direction, D6 thread limit for standard tolerance fits

Compatibility

Designed as a standard straight flute plug tap for cutting M16x1.50 metric fine right-hand internal threads. Fits standard tap holders, collet chucks, and tapping heads accepting the corresponding shank diameter.

Installation Notes

Installation should be performed by a machinist or qualified toolroom technician using a calibrated tap wrench, drill press, or CNC tapping cycle. Always drill the correct tap drill size for M16x1.50 metric fine thread before tapping, and use a quality cutting fluid or tapping oil to extend tool life and improve thread finish. Secure the workpiece firmly before tapping to prevent misalignment. Reverse the tap periodically to break chips when working in blind holes or gummy materials.
