Mũi khoan xoắn chuôi lục giác Loại N - 4.2 mm

• Preparing the hole before tapping or insert repair starts
• Supporting a controlled transition from drilling to threading without changing the planned thread designation
• Using a drill stage that suits workshop, maintenance and small batch threading preparation
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: cắt ren, taro lại ren, and làm sạch ren depending on condition

Lưu ý Select the product by thread designation, workpiece condition and the holder concept used in your process.

• Thread related geometry and designation are clearly assigned in the product name for practical selection
• Suitable for workshop, maintenance and machine room workflows with repeatable tool use
• The explicit standard and material markings support controlled tool assignment in professional use
• A dedicated threading tool reduces compromise compared with improvised general purpose tooling

• Tool selection still depends on matching the thread system, material and process type to the actual job.
• It is intended for defined threading work and not for undirected high speed use without the correct setup and lubrication strategy.

1. Secure the workpiece and mark the drilling location for the intended threading operation.
2. Clamp the drill securely in the machine or holder used for the preparation step.
3. Align the drill to the workpiece and start the hole with controlled feed.
4. Continue drilling with stable chip evacuation until the preparation hole is complete.
5. Remove chips from the hole and verify that the bore is ready for the next threading step.
6. Clean the drill and protect the cutting edges after use.
