- Use the set when you want a matched drill and tap pairing for a defined thread designation.
- Use for ISO metric threads as designated in the product name.
- Use for lỗ bít or lỗ thông based on lead form and flute geometry.
- Use a drilling and tapping setup that keeps both tools square to the surface.
- 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

How do you select the correct variant for your drawing
Match the thread designation in the product name to the drawing and the mating fastener. Confirm thread series, pitch, and class of fit before you start, especially for inch based threads.

Is this tap suitable for lỗ bít or lỗ thông
The suitability depends on flute geometry and lead form noted in the product name. Spiral flute execution is typically chosen for lỗ bít because chips are transported out of the hole.

Which tolerance class do you typically achieve
The typical tolerance class for this execution is ISO 2 (6H) when the process is set up correctly and the hole preparation matches the thread system.
Do you need cutting fluid
Yes, use suitable cutting fluid for the material to reduce friction and control chip formation. Keep lubrication consistent from start to finish and clean the tool after use.
Which tools do you need in addition to the kit
You typically need a suitable holder for the tap and a stable drilling setup. Use clamping that keeps the tool axis square to the surface and prevents wobble.
