Short Machine Tap DIN 2181 Form D HSS-G - M 14 x 1.0

The VÖLKEL Short Machine Tap is a specialized threading tool capable of creating a complete and standard-compliant fine thread in a single pass in a pre-drilled hole. Unlike traditional hand tap sets, which consist of multiple cutters (taper, plug, and bottoming taps), this short machine tap combines all necessary cutting stages into one powerful tool.

Its special capabilities and features:

• Single-Pass Efficiency: It cuts the complete thread form in one pass, saving you valuable working time and simplifying the process.
• Versatile Application: Designed for flexible use, you can employ this tap both manually with a suitable tap wrench and in machine applications such as drilling machines or milling machines. This versatility makes it a true all-rounder in your workshop.
• For Any Hole Depth: Whether you want to cut threads in through holes (which exit the other side of the material) or blind holes (which have a bottom), this tap is optimized for both and consistently delivers precise results.

This high-performance tool is aimed at anyone who needs to work precisely and reliably in metalworking. This includes:

• Industrial Mechanics and Machine Builders: For quick repair or new production of components.
• Tool and Mold Makers: Where the highest precision in thread manufacturing is required.
• Locksmiths and Metalworkers: For stable connections in constructions.
• Demanding DIY Enthusiasts: Who value professional results and want to invest in high-quality tools.

Your problem, our solution:

Imagine you quickly need an M 14 x 1.0 fine thread, but you have limited time or space. With conventional methods, you might need to use multiple steps or tools. The VÖLKEL Short Machine Tap solves this by:

• Saving Time and Reducing Complexity: No need to switch between different taps – one tool, one operation.
• Minimizing Sources of Error: The all-in-one solution reduces the risk of application errors that can occur with multiple steps.
• Increasing Work Efficiency: You can work faster and thus more productively, which is particularly beneficial for series production or recurring tasks.

There are many taps on the market, but the VÖLKEL Short Machine Tap stands out due to specific features that offer you real added value:

1. Metric ISO Fine Thread DIN 13 – The Specification for Precision:

The metric ISO fine thread according to DIN 13 is crucial when maximum precision and load-bearing capacity are paramount. Unlike coarse threads, a fine thread has a smaller pitch (in this case, 1.0 mm instead of the usual 2.0 mm for M14 coarse thread). This results in:

• More Engaged Threads: For higher strength and better security against loosening.
• Thin-Walled Materials: Ideal for applications where only limited material thickness is available.
• Finer Adjustment: Allows for more precise settings in precision mechanical and hydraulic systems.
• Leak-Tightness: Often indispensable for leak-free connections in pressurized systems.

2. DIN 2181 and Form D – Your Guarantee of Compatibility and Performance:

DIN 2181 is the binding German industrial standard for this type of tap, ensuring consistent quality and interchangeability of tools. Form D refers to a specific cutting edge geometry of the tap, characterized by a very short lead of approximately 1.5 to 2 threads.

• Excellent for Blind Holes: Due to the short lead, the thread can be cut closer to the bottom of the hole, maximizing the utilization of the full thread depth.
• Less Space Required: Perfect for situations where you have limited room to start the tap.
• Lower Starting Force: As fewer threads engage simultaneously, the initial cutting force is reduced, leading to a smoother start.

3. HSS-G Material – Maximum Durability and Cutting Performance:

The abbreviation HSS-G stands for "High Speed Steel, Ground." This is a crucial quality factor:

• HSS: Offers excellent toughness and heat resistance, making the tap resistant to heat generated during cutting and thus increasing tool life.
• Ground (G): Indicates that the tap's geometry is precisely ground from solid material. This results in extremely sharp cutting edges, an excellent surface finish of the thread, and superior dimensional accuracy – factors that are critical for the quality of your thread.

4. ISO 2 / 6H Tolerance – Perfect Fit Guaranteed:

The 6H tolerance class is the industry standard for metric ISO threads. It ensures that the internal thread you cut will perfectly match standard external threads (e.g., screws of tolerance class 6g), providing a play-free yet smooth connection ideal for most general applications. "ISO 2" denotes the general accuracy class according to the ISO standard.

5. VÖLKEL Brand Quality – Your Trust in Proven Excellence:

1: What is the main difference between a short machine tap and a hand tap set?

A short machine tap (or single-pass tap) cuts the complete thread in a single operation, as it combines all cutting stages (taper, plug, and bottoming) into one tool. A hand tap set, on the other hand, consists of multiple separate tools that are used sequentially to cut the thread gradually. The short machine tap is faster, while the set can offer advantages for very hard materials or for precision work requiring multiple passes.

2: Can I use this tap in both steel and other metals?

Yes, this tap is specifically designed for easily machinable materials up to a tensile strength of 900 N/mm² as well as unalloyed and low-alloy steels. However, it is also excellent for other metals such as aluminum, brass, or cast iron, provided they fall within the specified strength range.

3: What does "M 14 x 1.0" signify?

"M" stands for metric thread. "14" is the nominal diameter of the thread in millimeters (here 14 mm). "x 1.0" indicates the pitch of the thread in millimeters (here 1.0 mm per revolution). Since the pitch is smaller than a standard M14 coarse thread (which would be 2.0 mm), it is classified as a fine thread.

4: Is Form D better than other lead forms for blind holes?

Yes, Form D, with its very short lead (approx. 1.5 to 2 threads), is ideal for blind holes as it allows the thread to be cut very close to the bottom of the hole. This maximizes the usable thread depth. Other forms (like Form C or Form B) have longer leads and are better suited for through holes or materials that require more extensive guidance.

5: What pilot hole size do I need for an M 14 x 1.0 fine thread?

For a metric ISO fine thread M 14 x 1.0, you typically need a pilot hole of 13.0 mm. It is always advisable to check precise tap drill charts, as material tolerances or drill variations might require slight adjustments.
