Drill bits, HSS-G, 8,5 (M10)

• Drill preparation holes for tapping, fastening, or assembly work where a compact bit tool is used in the holder.
• Select the drill bit diameter from the product name and match it to the required core hole or pilot hole.
• Keep the bit aligned and remove chips from the hole so the following operation starts cleanly.
• 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 Verify the workpiece preparation, thread designation, and holder alignment before starting. Stop if torque rises suddenly or if the tool no longer follows the hole axis.

• The diameter stated in the product name makes selection direct for the required hole preparation.
• The HSS-G execution gives a clear material designation for the drill bit.
• The bit format supports compact tool storage and mobile workshop use.
• Clean hole preparation supports more reliable follow up assembly or tapping work.

• The drill bit does not create a finished internal thread by itself.
• Hole quality still depends on alignment, speed, feed, and chip removal.

1. Confirm the required hole diameter from the product name and work instruction.
2. Secure the bit in the holder so it runs without visible wobble.
3. Mark or position the hole location on the workpiece.
4. Start drilling with controlled pressure and stable alignment.
5. Withdraw the bit regularly when chips must be removed from the hole.
6. Finish the hole and remove burrs or loose chips from the entry.
7. Check the hole before the following tapping, fastening, or assembly operation.

• 1 piece Drill bits, HSS-G, 8,5 (M10)

• Product type: Drill bit
• Tool material: HSS-G
• Thread system: Metric ISO

How do you select the correct variant

Select the thread designation stated in the product name only when it matches the drawing, mating component, and required process. Also check the tool type, material designation, and holder or machine setup before use.

What does Metric ISO mean in this product context

Metric ISO threads use the M designation and are common in mechanical engineering, maintenance, and standard fastening work.

Does this product create a finished thread

The drill bit prepares the hole only. A tap or forming tool is still required when the work instruction calls for a finished internal thread.

How do you choose the correct drill diameter

Use the diameter stated in the product name and match it to the tapping table, work instruction, or component drawing.

What does HSS-G tell you

HSS-G is the tool material or execution stated in the product data. Use it as a selection fact together with thread designation and tool geometry.
