Mũi khoan, HSS-G, 3,3 (M4)

• Produce holes for fasteners, pins, and general fabrication work in workshop and site service.
• 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
• Use a suitable Chất bôi trơn cắt gọt ren for the work material and keep the tool aligned to the axis.

Lưu ý Clear chips frequently to reduce friction and to keep the cutting edges protected.

• General purpose hole making for workshop tasks
• Stable cutting edges when your setup is consistent
• Suitable for preparation steps before threading and assembly
• Simple tool selection when diameter is defined in the product name
• Suitable for routine use in metal fabrication and plant engineering service

• Not suitable for every work material without correct cutting fluid and stable alignment
• Practical speed is limited by manual handling and by access conditions at the workpiece

1. Mark the drilling point and secure the workpiece with stable clamping.
2. Center the tool and start with straight alignment to the surface.
3. Apply suitable lubrication for the work material if your process requires it.
4. Drill with consistent feed while allowing chips to evacuate freely.
5. Retract to clear chips when needed and avoid rubbing at low feed.
6. Deburr the hole edge and clean the bore before the next process step.

How do you select the correct thread designation for this product Match the thread designation in the product name to the mating fastener or component standard, then confirm that your workpiece material and process setup suit the tool type. If you work with mixed standards, separate your tooling by thread family to avoid mix ups. How do you select drilling parameters Set speed and feed based on the work material and your machine capability, then adjust to maintain stable chip evacuation. Use lubrication where needed and avoid rubbing. If the bore will be threaded, keep the hole round and the entry edge clean. Which hole preparation checks matter most Prepare the entry edge, remove burrs, and keep the hole clean so the tool starts straight. In lỗ bít, confirm that there is enough depth for the tool lead and chip space. In lỗ thông, support chip evacuation out of the exit side. How do you reduce the risk of misalignment Start the tool with the axis visually aligned, then guide it through the first turns with low torque. Use stable workholding and avoid side load. If a thread feels tight early, remove the tool, clean chips, and inspect the entry. Can this be used for thread preparation If the product name indicates a thread preparation context, use it as the drilling step before tapping or forming. Follow your tapping chart or process sheet for the correct drill assignment. Keep the hole clean before the threading step.
