CPMH090304-SV US735
High-Toughness Finisher | US735 Impact Barrier | SV Precision Geometry
Engineered for Precision in Harsh Conditions
US735 Grade (Stainless Impact Specialist): The US735 is a CVD-coated grade that defies the standard "brittle" nature of finishing tools. Specifically optimized for M-Class (Stainless Steel), it features a unique substrate that absorbs mechanical shock. This makes it ideal for finishing passes on parts with cross-holes, keyways, or uneven surfaces that would otherwise shatter a standard finishing grade.
SV Chipbreaker (Low-Force Precision): The SV geometry is a light-cutting, small-cut chipbreaker. It features a highly positive rake angle that "slices" rather than "pushes" the material. This sharp action is critical for preventing work-hardening of the stainless surface and reducing radial forces that cause chatter in slender boring bars.
0.4mm (1/64") Radius: The 04 radius is the precision standard. It allows for the finest surface finishes (Ra) and generates the least amount of heat at the tip, ensuring dimensional stability throughout the cut.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CPMH090304-SV | 9.525 mm | 3.18 mm | 0.40 mm |
| Imperial | CPMH321-SV | 3/8" | 1/8" | 0.0157" (1/64") |
Precision Cutting Parameters
*SV geometry performs best at low feeds. For interrupted cuts, maintain speed but decrease feed slightly for edge safety.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Stainless 304/316 | 90 - 170 m/min | 0.04 - 0.12 mm/r | 0.10 - 1.20 mm |
| High Strength Alloy | 70 - 140 m/min | 0.03 - 0.10 mm/r | 0.08 - 1.00 mm |

US735 (Toughness First): Your primary choice for interrupted cuts or when the machine setup is not perfectly rigid.
US7020 (Wear Resistance First): Switch to US7020 for continuous, stable turning at higher speeds to extend tool life when shock is not a factor.

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.
