Description

HexTap Type DS - Double ended tap, Multi-Drive Form C HSS-G - UN 1.3/8 x 8

Use this HexTap Type DS for fixture making and on site repair when you need to produce or refresh UN internal threads in prepared holes.

Form C chamfer and HSS-G execution give you predictable entry and cutting behavior, and the Multi-Drive interface supports workshop style driving methods.

Application

Create UN internal threads on housings, jigs, and adapters after drilling operations.
Re tap threads that show tight running due to coating, dirt, or small burrs.
Prepare threads for bolted joints in equipment builds and retrofits.
Use where you need a robust, portable threading tool for on site interventions.

Note Use stable workholding and apply cutting fluid consistently to reduce friction and heat during thread cutting.

Benefits

Supports UN internal thread production and correction without switching tools repeatedly.
Multi-Drive interface helps you work with limited swing radius.
Form C chamfer supports predictable lead in behavior.
HSS-G material supports wear resistance in common steels and alloys.
Practical for on site work where a full tap set is not available.

Drawbacks

Not suitable for brittle materials that tend to chip at the thread entrance without careful setup.
Not intended for continuous industrial tapping lines where cycle time dominates.

Step by step

Confirm the UN thread requirement before you set up the tool.
Deburr the hole entrance to support stable lead in.
Fix the component securely in a stable position.
Use a Multi-Drive holder that supports straight guidance. Technical information HexTap DS as PDF
Wet the cutting edges with suitable cutting fluid.
Start cutting with smooth rotation while keeping the axis aligned.
Cut the thread while preventing chip packing through regular clearing.
Verify engagement and surface finish after cleaning.

Frequently asked questions (FAQ)

What does UN 1.3/8 x 8 mean on the product name? It identifies the UN thread size and the pitch in threads per inch as written on the tool. Match it to the mating fastener or drawing, and avoid mixing similar UN sizes. What is the practical advantage of the two working ends? Two ends can reduce tool changes during rework. Choose the working end that supports the desired starting behavior and thread quality, depending on execution. How do you reduce the risk of drive slip with Multi-Drive? Use a driver that fully engages and keep the interface clean. Apply torque smoothly to avoid shock loads. How does chamfer Form C influence starting behavior? It affects the lead in length and the way the tap enters the material. Use careful alignment at the first turns regardless of chamfer form. How do you protect tool life in tougher materials? Use suitable cutting fluid and keep alignment correct to avoid edge chipping. If cutting forces are high, review hole preparation and tool choice. Is thread cleaning the same as thread repair? Thread cleaning removes contamination and corrects small deformations. Thread repair rebuilds the thread with an insert when the original profile is no longer usable.
