Wiseman Threading Tools Spiral Flute Tap, M16x2 with +0.015 tolerance is built for precision in internal threading, delivering clean, repeatable threads in demanding workpieces. Designed to cut with a focus on reliability, this tap helps you achieve accurate fit and finish in critical assemblies without guesswork.

The standout feature is the spiral flute design, engineered to actively evacuate chips as you cut. That means fewer interruptions from chip packing, smoother cutting action, and reduced risk of tap breakage when threading into deeper holes or tougher materials. The result is consistent thread geometry from the first pass to the last, even on challenging projects.

With a +0.015 tolerance, this Wiseman spiral flute tap maintains tight, dependable thread dimensions, ensuring mating parts thread in smoothly and stay within spec across production runs. Precision like this minimizes rework and extends the life of your components by preventing out-of-tolerance fits.

Durability is at the core of its construction. Crafted from high-quality materials, the tap is built to withstand the rigors of metalworking environments—from prototype runs to small-batch production. That robustness translates to longer tool life and more consistent performance, helping shops meet tight deadlines without frequent tool changes.

This tapping solution is ideal for machinists and metalworkers who need reliable internal threads in M16x2 applications. Whether you’re setting up new components, repairing damaged threads, or producing parts that demand exacting dimension control, this spiral flute tap helps you achieve clean, accurate threads with fewer passes and less fuss.

Key use scenarios include:

• Creating precise internal threads in steel, aluminum, and cast parts where chip evacuation is critical.
• Deep or blind-hole threading where conventional straight-flute taps may clog or stall.
• Production environments where consistent thread dimensions translate to reliable assembly fit and performance.

How to maximize results with this tap:

• Use with standard tapping equipment and appropriate lubrication to extend cutting life and improve surface finish.
• Ensure the workpiece is securely clamped and aligned to prevent cross-threading or runout.
• Follow recommended tapping speeds for the material to balance chip evacuation with surface finish quality.
