— Giuseppe F., Italy 🇮🇹Frequently Asked Questions
Q: Is YBM251 better than YBM151 for interrupted cuts?
A: Yes. YBM251 has higher toughness than YBM151, making it more resistant to chipping during light to medium interrupted cuts in stainless steel.
Q: Can this insert be used on Carbon Steel (ISO P)?
A: While optimized for Stainless (ISO M), YBM251 can be used on low-carbon steels in a pinch, but for high-volume steel work, YBC251/252 is recommended.
Q: What does the 'HM' stand for?
A: 'HM' is the chipbreaker style, standing for Medium-Duty machining. It provides a balance between cutting edge strength and chip breaking capability.

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.
