Description

Machine Tap BLUE RING JIS B-4430 Form C 39° Spiral Flute HSSE - M 14 x 1.25

With this machine tap you cut or form internal threads when repeatability and alignment are critical. The product name indicates the standard and geometry so you can choose the correct variant for your part.

You typically run the tool in a tapping chuck or a suitable collet holder with axial compensation if required. Process stability depends on correct lubrication, clean chip evacuation, and avoiding misalignment at entry.

Application

Cutting of internal threads in steels and common engineering materials within the limits of the chosen execution
Use for series work, repair tasks, and general machining in mechanical engineering and metal fabrication
Suitable for through holes and blind holes depending on the geometry stated in the product name
Use with a tapping chuck or suitable collet holder to keep axial alignment during the tapping cycle
Process: manual driving or assisted driving depending on your holder and machine setup
Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Use a suitable cutting lubricant for the workpiece material and remove chips from the flutes before storage.

Benefits

Suitable for workshop and series processes when lubrication and alignment are controlled
Supports rework and maintenance tasks without changing the workpiece design
Defined cutting geometry supports predictable thread form
Clear variant identification via standard and form in the product name

Drawbacks

Tool life can drop in very hard or abrasive materials if the selected execution is not matched to the application
Not suitable for high performance applications when process parameters are not optimised

Step by step

Confirm the thread designation, standard, and execution in the product name against your drawing and material specification.
Prepare the pre hole and entry chamfer according to your process specification and remove burrs from the opening.
Clamp the tap in a tapping chuck or suitable collet holder and set up the cycle so feed stays synchronised with rotation.
Apply a suitable cutting lubricant or coolant for the workpiece material and ensure the entry area is wet.
Start the cut with the tool aligned to the hole axis and keep the alignment stable through the first turns or revolutions.
Continue the pass while monitoring torque and remove the tool if chips accumulate and increase cutting resistance.
Retract the tool, clean chips from the flutes, and inspect the thread before the part moves to the next operation.

Frequently asked questions (FAQ)

What should you check before you start tapping with this tool? You verify the thread designation shown in the product name and confirm that your pre hole preparation meets your internal process specification. You also check the workpiece material and choose a lubricant that prevents seizing. Which holder type do you typically use with this tap? You typically use a tapping chuck or a suitable collet holder so the tap runs concentrically and stays aligned. If your process needs axial compensation, you choose a holder that provides it. How do you reduce the risk of broken taps and damaged threads? You keep the tool aligned, use a suitable lubricant, and monitor torque so you can stop before overload. You also remove chips from the flutes and avoid starting on burrs or hard scale. Where can you find additional process notes for machine tapping? Use the PDF for consolidated notes on selection and handling. Technical information machine taps as PDF Do you need cutting lubricant or coolant for this tap? Yes, you use a lubricant or coolant matched to the workpiece material to reduce friction and to control heat. Stable lubrication also helps keep thread flank quality consistent. How do you maintain and store the tap after use? You clean chips from the flutes, dry the tool, and apply a light corrosion protection film. You store it so cutting edges are protected from contact and impact. Where can you find additional technical data and the full range? Use the catalog for overview tables and selection guidance.
