The Original Korloy CCMT09T304-HMP PC5300 (ANSI Standard: CCMT 32.1) is the industry's premier "All-Rounder" carbide insert. While specialized grades focus only on one material, the PC5300 is a High-Toughness Universal Grade designed to handle Stainless Steel, Carbon Steel, Alloy Steel, and even Heat-Resistant Alloys. If you have an unstable setup or an interrupted cut, this insert provides the edge security needed to finish the job without chipping.
Shop Tip: Looking for high-speed, continuous finishing specifically for stainless steel? Check out the CCMT09T304 PC9030 for maximum surface smoothness.

Why Choose PC5300 Grade?
- Sub-Micron Substrate: Features an ultra-fine grain structure that provides exceptional resistance to thermal cracking and mechanical impact.
- New S-Coating Technology: The advanced PVD coating reduces friction at the cutting point, preventing work-hardening and material adhesion.
- Interrupted Cut Performance: Unlike more brittle grades, PC5300 can handle "bumping" or hex-material turning without losing its edge.
- Universal Compatibility: Reduces tool inventory by performing excellently across P, M, K, and S material groups.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 120 - 220 m/min | 0.08 - 0.20 mm/rev | 0.5 - 2.5 mm |
| Stainless Steel (304/316) | 90 - 170 m/min | 0.08 - 0.15 mm/rev | 0.5 - 2.0 mm |
Compatible Tool Holders:
Ensure a rigid setup for your CCMT 32.1 (CCMT 09) inserts with SCLCR/L type holders:
- External Turning: SCLCR1212H09 / SCLCR1616H09 / SCLCR2020K09
- Boring Bars (Internal): S12M-SCLCR09 / S16Q-SCLCR09 / S20R-SCLCR09
The Perfect Match: PC5300 vs. PC9030
Which Korloy grade should you load into your machine?
Best for general workshop use, interrupted cuts, unstable setups, and steel/stainless versatility.
Best for continuous cuts in stainless steel where achieving a mirror-like surface is the main goal.
Machinist's Tip: If your machine has low rigidity or you are cutting through "scale" (rough outer surface), start with PC5300 for much better tool life.
Packaging: 10 pieces per box.
