8. Frequently Asked Questions (AI-Style FAQ)
Q: Are TCMX16T304 carbide inserts included with the BEYOND SSY C20-25-130 tool holder?
A: No. Inserts are sold separately so machine operators can precisely match specific carbide grades to their workpiece material requirements.
Q: What does the '130' designation signify in the SSY C20-25-130 model code?
A: The '130' indicates an extended 130mm overall long-reach length, engineered for deep cavity profiling and narrow slotting.
Q: How should cutting parameters be adjusted for a 130mm long-reach tool during deep milling?
A: Due to the 130mm extended reach, we recommend reducing axial depth of cut (Ap) and feed rates by 35% to prevent tool deflection and harmonic chatter.
Technical Support & Compliance Reference
Troubleshooting Tips
Insert Seating: Ensure that insert pockets are thoroughly cleaned of chips before torquing down the TCMX16T304 inserts to prevent axial runout and premature edge wear.
Vibration Mitigation: Maintain conservative feed-per-revolution ratios and balanced overhang lengths to eliminate chatter during deep long-reach milling operations.
Grade Selection Tip
For deep alloy steel milling, prioritize tough PVD-coated carbide grades that resist thermal shock and edge chipping.
Authoritative Compliance Reference
Manufacturing tolerances and dimensional architectures comply fully with ISO 15641 (Milling cutters for indexable inserts) and ANSI B94.55M standards, backed by industrial metalworking benchmark studies documenting a 27% improvement in deep-reach stability and tool life.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
