Hand Tap Finisher DIN 40432 HSS-G - PG 9 x 18

• Cut internal threads in pre drilled holes in mechanical engineering, plant engineering, and maintenance work
• Use a suitable tap wrench to keep the tool aligned and to control torque during manual cutting
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: thread cutting, re tapping, and thread cleaning depending on condition
• Apply a suitable cutting lubricant to reduce friction and improve surface quality

Note Verify the thread standard and the hole form before you start, and keep the tool and thread clean throughout the operation.

• Supports controlled thread cutting when you work manually and need direct feedback on torque
• Suitable for repair work and for low to medium batch sizes in workshop environments
• Matches common tap wrench use for controlled starting and alignment

• Cutting performance is limited in very hard materials or where poor chip evacuation occurs
• Not intended for high performance production without a stable machine process and tool monitoring

1. Check that the pre drilled hole and chamfer match the thread standard named on the tool
2. Secure the workpiece and set the tap straight to the hole axis before you start cutting
3. Apply a suitable cutting lubricant and begin turning with steady torque
4. Advance the tap gradually and clear chips from the flutes as needed without forcing the tool
5. Maintain alignment through the cut and stop if torque rises sharply to avoid tool breakage
6. Reverse the tap to remove it and clean the new thread and the tool before storage

How do you confirm that the tool matches PG 9 x 18?

You check that the thread designation, pitch or threads per inch, and standard in the product name match your drawing and the mating part.

What preparation is important before you start?

You ensure the hole or diameter is prepared, the start chamfer is present, and the workpiece is rigidly clamped so alignment stays stable.

Which holder type do you typically use with this tool?

You typically use a suitable tap wrench for manual cutting so you can keep the tool square and control torque.

Where can you find guidance on hand tapping practice?

You can use the technical information document for practical handling notes and selection hints. Technical information hand taps as PDF

How do you clean and store the tool after use?

You remove chips and residue, dry the tool, and apply a light corrosion protection film where appropriate before storage.

What do you do if torque rises sharply during cutting?

You stop, reverse the tool to relieve load, clean the cutting area, and verify alignment and lubrication before you continue.
