Spiral Pointed Tap - Overview
A spiral pointed tap, also known as a "gun tap," is a type of tap specifically designed to create internal threads in through holes by pushing chips forward and out of the hole ahead of the cutting action. This chip-ejection method, achieved with a gash in the front of the flute, prevents clogging and allows for faster, more efficient tapping by keeping the tap's flutes free of debris.

Features of Spiral Pointed Tap
Spiral Point Design
Directs chips forward to prevent clogging and reduce breakage.
Optimized for Through Holes
Best suited for applications where chips can exit the opposite side of the workpiece.
Straight Flute Construction
Ensures high rigidity and precise threading performance.
High Efficiency
Compatible with CNC and automated systems for fast, reliable tapping.

Spiral pointed taps have straight flutes that provide efficient coolant distribution. Each flute is equipped with an angular design at the cutting chamfer to better manage the chips. Spiral pointed taps push the chips forward, ahead of the tapping direction.

Manufactured Process




Raw Material Selection and Preparation
Material: High-speed steel (HSS) or cobalt-based high-speed steel are standard choices for spiral point taps, offering toughness and heat resistance for demanding applications. Other possible materials are High-Speed Steel (HSS), Cobalt High-Speed Steel (HSS-Co), Powdered Metal (PM), High-Performance High-Speed Steel (HP-HSS), Carbide, Titanium Nitride (TiN), Titanium Carbonitride (TiCN), Titanium Aluminum Nitride (TiAlN), Diamond-like Carbon (DLC), Aluminum Titanium Nitride (AlTiN)
Stock Preparation: The HSS bars are cut to approximate length and heat-treated for increased hardness and wear resistance.
Blank Grinding
Forming the Basic Shape: The tap blank is rough ground to achieve the overall diameter and basic shank shape.
Flutes: Flutes are milled to an initial, shallower-than-final, depth into the blank. This is usually done on specialized flute milling machines.
Thread Grinding
Precision Threading: Thread grinding machines use high-speed, precision grinding wheels to cut the exact thread form into the tap, ensuring accuracy and meeting specifications (pitch, diameter, thread class, etc.).
Spiral Point Creation
Specialized Grinding: A separate machine and grinding wheel profile is used to form the spiral point. This creates the angled chamfer and chip-driving gash characteristic of these taps.
Surface Treatments and Finishing
Heat Treatment: Additional heat treatments (like nitriding or vapor deposition) may be applied to further increase surface hardness and wear resistance.
Surface Polishing: The tap is polished to improve chip flow and reduce friction.
Marking: Taps are marked with essential information like size, thread type, material, and manufacturer.
Quality Control
Dimensional Checks: Threads, diameters, and flute depths are meticulously checked against standards using gauges and measuring instruments.
Hardness Testing: Hardness tests ensure that the heat treatments achieved the desired results.
Visual Inspection: Taps are inspected for surface defects or any imperfections.
