First decision of the day: choosing a tap holder for the Roscamat Tiger.
Know the Basic Size Range
Typically a holder will be rated for a range of sizes from M3 up to M12. Holders for fine work (M3 to M6) are usually specified as separate items to holders for general work (M8 to M12).
Match the Shank Diameter Carefully
5 mm collet, then the tap will run off centre and likely to try and tear the thread.
Consider Material Thickness and Thread Depth
The depth of the thread in the workpiece (especially thicker steel workpieces) can produce a large amount of torque within the holder. Holders designed for use on lighter work (such as thin sheet metal) may slip or wear prematurely under these conditions. In general a holder designed for use on work up to 6mm deep in mild steel would not be suitable for use on deeper or thicker work. Roscamat Electric Tapping Machines is worth getting right.
Verify Compatibility Before You Order
Specific information for Roscamat Tiger holders would be cross-referenced for details on collet size, tap shank diameter, and tap sizes / work size etc. for more on Roscamat Electric Tapping Machines https://www.cotswold-machinery-sales.co.uk/roscamat-tapping-machines/electric-tapping-machines/roscamat-tiger-electric-tapping-machine/.
Check the Safety Angle Too
Risk of injury or damage when using mismatched tooling on powered rotating equipment for new operators or for checking current practice.
Getting the holder size right from the off will mean better threads, less broken taps and less time wasting trying to find out why your taps have broken.
