US735 Grade Technology
The US735 grade is Mitsubishi's specialized CVD turning insert material for M-class stainless steel. It features a high-toughness substrate combined with a coating that significantly reduces built-up edge (BUE). This makes it an elite long-tail industrial tool for high-mix, low-volume production where reliability is key.
MS Medium-Light Breaker
The MS chipbreaker is specifically optimized for medium-light cutting of gummy materials. Its sharp rake angle reduces cutting resistance, preventing the work-hardening of the stainless steel surface while maintaining efficient chip evacuation at lower feed rates.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed per Rev ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Austenitic Stainless (304/316) | 60 - 150 m/min | 0.08 - 0.20 mm/rev | 0.3 - 2.5 mm |
| High-Temp Alloys (Inconel) | 30 - 60 m/min | 0.08 - 0.15 mm/rev | 0.3 - 2.0 mm |
COMPATIBLE TOOL HOLDERS
Pairs perfectly with MTJNR/L or WTJNR/L external turning tool holders (Size 16).

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.
