Red Diamond Blade

Diamonds are a driller’s best friend

Increase your production rate with this new Melfred Borzall innovation that works harder and smarter than the average blade. The Red Diamond Blade design features a single front-end domed carbide for blunt force that extends the blade’s overall life. The new diamondshaped carbides on the front sides aggressively tear through hard ground conditions and the low-profile diamond carbides near the rear help to minimize drag. The continuous perimeter of carbides give the blade a mean look with a lethal bite. It’s a driller’s ace in the hole.

Performance Features:

  • Durable Domed Front Carbide
  • Diamond-shaped carbides on sides for aggressive cutting —100% carbide coverage
  • Continuous low-profile back carbides to minimize wear
  • Tapered design towards the rear to reduce drag
