Positive Rake Carbide Insert Bits, 10-Pack | Fits FMC Brake Lathes | Part #40410

Replacement positive rake carbide insert bits for FMC bench brake lathes. The positive rake geometry produces a clean, low-resistance cut on most modern rotor materials, finishing rotors with minimal heat buildup and reduced cutting force. Industrial-grade carbide composition delivers extended edge life across high-volume rotor resurfacing operations compared to standard tool steel cutters.

  • Part #: 40410
  • Quantity: 10 inserts per pack
  • Rake geometry: Positive
  • Material: Industrial-grade carbide
  • Application: Modern rotor resurfacing on FMC brake lathes
  • Lathe compatibility: FMC bench brake lathes
  • Function: Low-force, low-heat cutting with extended edge life
  • Recommended use: Cast iron and composite rotor materials

Frequently Asked Questions (FAQs)

What brake lathe models are these bits for?
While they fit many positive rake holders, they are the primary specification for: -FMC Brake Lathes -Bosch: Bench lathes utilizing the FMC style tooling system. -Ammco: Specific combination lathes equipped with the heavy-duty positive rake tool holder upgrade.
How do I prevent "chatter" when using these bits?
These FMC Style Positive Bits are a thicker, more rigid than other bits, it is excellent at dampening vibration. However, you must ensure the tool holder seat is perfectly clean. Even a tiny metal shaving under a "thick" bit can cause it to sit unevenly, leading to the "record-player" groove effect on the rotor surface.
Does the positive rake angle make a difference for rotors?
Yes. The positive rake slope of these carbide bits are specifically designed to "shear" rather than "scrape." High-carbon and composite rotors are prone to surface tearing; the sharp, positive angle peels the metal away cleanly, which reduces heat buildup and ensures a non-directional finish that meets OEM break-in requirements.
Can I use these FMC bits on an Ammco Brake Lathe?
No. If your lathe's holder is designed for the thinner bit, the FMC style bits will sit too high in the seat. This throws off the "centerline" of the cut, which can lead to severe chatter, poor surface finish, and potential damage to the tool holder or the lathe arbor. Always match the bit thickness to your specific tool holder style.
