Product Information
Full details
The Facom 251A.1 Precision Sleeved Drift Punch is an essential instrument for professional metalworkers and precision engineers who require extreme accuracy when driving pins or aligning components. Its standout feature is a sliding center guide sleeve that prevents the tool from deforming or slipping, ensuring pinpoint precision in delicate applications. While its specialized design is perfect for small-scale mechanical assembly, users should note that its slim 0.9mm profile is intended for delicate work rather than heavy-duty structural demolition.

FAQs
What is the primary advantage of the sleeved design?
The sleeve keeps the tip centered and prevents the punch from distorting, which is critical for precision tasks involving small pins.
Can I use this for driving out large roll pins?
No, this tool is specifically designed for 0.9mm precision work and should not be used on larger pins.
What is the hardness rating of the sleeve?
The sleeve is hardened to 52-57 HRC, depending on the specific dimensions.
Is this tool suitable for heavy industrial use?
It is a precision instrument intended for fine mechanical assembly rather than high-impact industrial tasks.
How do I maintain the polish on the tip?
Keep the tip clean and lightly oiled after each use to prevent rust and maintain its structural integrity.
Troubleshooting
Sleeve is sticking or difficult to slide
Clean any debris or metal filings from the sleeve interface and apply a thin coat of synthetic lubricant.
Tip is showing signs of mushrooming
Verify that the hammer being used is not too heavy and that the tool is being struck perfectly perpendicular to the pin.
Pros and Cons
Pros
- Prevents tool distortion via the integrated sliding sleeve
- Highly durable hardened steel construction
- Excellent for miniature and precision metalwork
- Professional-grade finish resists corrosion
Cons
- Limited to very small pin sizes due to 0.9mm diameter
- Not intended for heavy-duty industrial hammering
- Requires careful alignment to avoid tip damage
Setup, Compatibility & Care
To ensure the longevity of your 251A.1 drift punch, always use a precision mallet rather than a heavy sledge to avoid fracturing the 0.9mm tip. For optimal results, ensure the workpiece is supported on a flat, stable surface. Compatibility is best maintained with pins or dowels matching the 0.9mm diameter to prevent side-loading stress. After use, wipe the polished tip with a light machine oil to prevent oxidation and store in a dedicated tool roll or organizer to protect the precision-engineered sleeve from impact damage against other hard tools.
