BLUE RING TwinBox Machine Tap + Twist Drill, DIN 376, HSS-E, M 14 x 2.0

• 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 VÖLKEL uses and recommends spiral drills from LÖHER. LÖHER product catalog as PDF

• 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

• 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

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

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.

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.
