Wiseman Threading Tools Second Lead Metric HSS Tap Right Hand - M4x0.7

Wiseman Threading Tools Second Lead Metric HSS Tap — M4x0.7 is a precision-ground high-speed steel tap designed for durable, reliable internal threading in metalwork. Uncoated for broad compatibility and versatility, this tap follows ISO 529 dimensions, uses a right-hand thread, and employs a second-lead design to cut more aggressively with less effort.

• Material and finish: High-speed steel (HSS) ground for sharp cutting edges and long service life; uncoated to suit a wide range of metals and lubrication routines.
• Thread specification: Metric M4 x 0.7, right-hand thread; built to standard ISO 529 thread form for predictable fit and consistency.
• Lead design: Second lead means more thread starts per revolution, accelerating the cutting action, improving chip evacuation, and reducing insertion torque compared with single-lead taps.
• Usage scope: General-purpose tapping for internal threads in a variety of metals, suitable for both hand and machine tapping in line with ISO 529 guidelines.
• Standards alignment: Engineered to ISO 529 short-machine tap and hand-tap dimensions, ensuring compatibility with standard drilling and threading practices.

Practical scenarios this tap excels in include creating clean, precise M4 threaded holes in aluminum housings, steel brackets, or small mechanical assemblies where reliable engagement and smooth thread formation are critical. The second-lead geometry aids faster progress in through-holes or sleeves, while the uncoated finish invites effective lubrication to maximize tool life on a range of metals.

Tips for best results: keep the tap perpendicular to the workpiece to ensure true, round threads; apply light cutting lubrication to reduce wear and heat buildup; and use steady, controlled turns to let the tool form the thread evenly. This Wiseman HSS tap is a dependable choice when you need a metric M4 x 0.7 thread with consistent performance across a variety of metalworking projects.
