Description

Machine Tap DIN 376 Form C 35° Spiral Flute HSSE - UNF 3/4 x 16

This machine tap supports controlled internal thread cutting when you run a stable setup with reliable alignment and lubrication.

Select the geometry and chamfer form to match the hole type and the desired process stability, and verify the thread designation before you start. The execution follows DIN 376. Form C defines the chamfer and lead-in behavior.

Application

Cut internal threads in pre-drilled holes using a controlled machine process.
Use a machine tap holder, collet system, or tapping attachment suited to the tap shank and drive.
Spiral flute geometry is commonly selected for blind holes because chips are drawn back along the flutes.
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 cutting fluid suited to the workpiece material and keep the tool clean and protected after use.

Benefits

Helps you achieve repeatable internal thread form in workshop conditions
Enables controlled chip transport when cutting fluid and reversal are managed
Fits typical tap holding systems appropriate to the tool type
Reduces risk of cross-threading when the tool is started square
Helps you maintain process control across single parts and small batches

Drawbacks

Limited suitability for very hard materials unless a dedicated execution is specified
Not suitable for uncontrolled hand tapping without a guided holder

Step by step

Confirm the thread designation and ensure the workpiece hole is prepared and free of burrs.
Secure the workpiece so the hole axis is stable during the tapping cycle.
Mount the tap in a suitable machine tap holder and check that the tool runs true.
Apply cutting fluid suited to the workpiece material.
Align the tool to the hole axis before you start the tapping cycle.
Run the tapping cycle with controlled feed and observe chip evacuation.
Withdraw and clear chips when needed so chips do not pack in the flutes.
Clean the thread and the tool, then protect the cutting edges for storage.

Frequently asked questions (FAQ)

When should you use a machine tap instead of a hand tap Use a machine tap when you can guide the tool with a machine spindle and a suitable tap holder, and when you want controlled feed that matches the thread pitch. What holder type do you need for this tap Use a machine tap holder, collet system, or tapping chuck that supports the tap shank and keeps alignment to the hole axis stable. What preparation is required before you tap the thread Prepare the core hole to the correct size for the thread designation, remove burrs, and add a small lead-in chamfer so the tap can start without side load. How do you control chips and cutting fluid during tapping Use cutting fluid suited to the workpiece material and clear chips regularly, especially in deeper holes or tougher materials, to prevent chip packing and tool overload. Where can you find additional technical information for this execution Use the following PDF for reference on inch threads and conversions: Inch to mm conversion table as PDF How do you reduce risk of tap breakage Keep alignment stable, avoid side load at entry, and stop if torque rises sharply so you can inspect hole preparation, lubrication, and chip evacuation. Where can you find more product and application information in the VÖLKEL catalog Use this catalog for additional details and related items: VD 23 catalog as PDF How do you inspect the thread after tapping Check that the thread is clean, that the start is not damaged, and that the functional fit matches the mating component used in your assembly.
