See It In Action

  • Built to resist snapping under higher feed rates, getting you through each job faster.
  • Engineered for consistency, every bit performs the same, with no exceptions.
  • Micrograin solid carbide keeps edges sharper for longer, so you're getting crisp cuts at high feed rate. Not just when the tool's fresh.
  • Micro-Grain Solid Carbide Up Cutters have been Tested and proven to considerably outlast alternative standard 'solid carbide' bits.
  • Expect a clear improvement in sheet count per bit over any compression cutter you've used before.
Details

Check out our Micro Grain Solid Carbide Spiral Two Flute Up Cutter, featuring 2 flutes and built to outlast standard solid carbide bits, a claim we've tested meticulously to back up. Available in a range of different sizes.

What is Micro-Grain Solid Carbide?

Micrograin solid carbide uses carbide grains down to 0.5 to 0.8 microns, versus 2 to 5 microns in standard carbide. Finer grain means a harder edge without the usual loss in toughness, so it resists chipping and heat softening under load. Result: the edge stays sharp and accurate far longer, especially when compared to standard solid carbide bits.

These Two Flute Up Cutters bits are built for CNC and router applications requiring high feed rates and prolonged tool life. They work great across wood sheet materials, plastcis,foam boards and composites.
