Upgrade your machining with the Korloy XOMT060204-PD (grade PC3700) — engineered for steel cutting, built for performance.

Key Features & Specs

  • Geometry: XOMT (central drill insert style), with chip breaker PD (general-purpose / steel)

  • Grade & Coating: PC3700 — tough substrate + high-hardness, lubricative PVD coating for low friction and excellent wear resistance

    Smooth coated surface minimizes built-up edge and ensures consistent chip evacuation at high speeds 

  • Designed specifically for steel milling / turning / heavy cutting applications, especially in high feed / high depth-of-cut scenarios

Why It’s a Best Seller:

  • Extended tool life & high productivity: PC3700 improves chipping and breakage resistance compared to legacy grades, giving more stable tool life under varying conditions 

  • Less downtime: fewer insert changes thanks to its robustness, meaning longer uninterrupted runs

  • Better surface finish: by reducing built-up edge and erratic tool behavior, parts come out smoother

  • High wear resistance: maintains edge integrity under heavy cuts and interrupted cuts, even in wet machining

🏭 Application Industries

Ideal for machining in:

  • Automotive (gear blanks, shafts, components)

  • Aerospace (structural steel parts)

  • Die & mold (housings, tooling steel)

  • General engineering / heavy equipment (shafts, flanges, forgings)

Frequently Asked Questions

It’s optimized for steel / alloy steel / pre-hardened steel applications. The PC3700 grade is designed especially for steel machining, offering excellent performance in high feed and interrupted cuts.

Yes — though PC3700 is primarily characterized in milling, its toughness and coating design make it usable in turning & general steel cutting as well, within reasonable parameters.

Compared to PC3500 and PC3600, PC3700 shows better resistance against chipping and breakage, delivering longer tool life and better stability under tough cutting conditions

The PD chip breaker is a general-purpose chip control design, balancing stability and chip control across a range of feeds. The XOMT geometry is central/insert style, suited for chip management and stable seating in drill or milling systems

Since actual values depend on workpiece, rigidity, and machine, Korloy’s data suggests that PC3700 supports high feed and high speed machining, with stable tool life even at deeper cuts. Always start at moderate parameters and fine-tune according to your setup.
