FAQs
Does this set include drill bits?
No, this set contains 21 precision-ground taps only and does not include the corresponding drill bits.
What is the benefit of cobalt over standard HSS?
Cobalt steel is harder and offers significantly better heat resistance, meaning the cutting edges stay sharp longer when working with tough or abrasive materials.
Can I use these for hand tapping?
Yes, these taps are designed for precision hand tapping, though they should always be used with a compatible, high-quality tap wrench.
Are these taps suitable for blind holes?
Yes, the set includes bottoming taps specifically designed to finish threads to the bottom of blind holes.
What is the weight of the complete set?
The total weight of the set including the metal box is 720g.
Are replacement taps available for this set?
As this is a comprehensive kit, it is recommended to contact a Facom authorized dealer if you need to replace a specific tap size.
Troubleshooting
Tap is binding or becoming hard to turn
Back the tap out periodically to break the chip, and ensure you are using sufficient cutting oil.
Poor thread finish
Check if the tap is dull or if the pilot hole was drilled to the incorrect diameter for the thread size.
Tap broke during operation
Ensure the tap is perfectly aligned with the hole and avoid applying excessive lateral pressure during the cutting process.

Setup, Compatibility & Care
To maximize the life of your 227.SJ1 set, ensure your workpiece is securely clamped to prevent vibration, which can lead to tap snapping. Always use a high-quality cutting oil or tapping fluid appropriate for the material you are working with to reduce friction and heat buildup.
- Alignment: Ensure the tap is perfectly square to the hole surface before starting the initial turn.
- Cleaning: After each use, wipe down the taps with a clean cloth to remove metal shavings and old oil before returning them to the designated slots in the metal case.
- Storage: Keep the case in a dry area to prevent oxidation and ensure the tools remain in factory-ready condition.
