Freud 16-520 Mortising Bit, 3/4-Inch

Freud

Purpose-built for mortise routing -- the most common plunge routing application

  • 3/4-inch mortising bit
  • Perma-SHIELD coating
  • TiCo carbide
  • For mortise and tenon joints

Pros

  • Purpose-built for mortise routing -- the most common plunge routing application
  • 3/4-inch width matches common tenon thicknesses in furniture-scale joinery
  • TiCo carbide produces clean mortise walls without tearout in most hardwoods
  • Perma-SHIELD coating reduces friction and pitch buildup during repeated plunge cuts

Cons

  • Single fixed width -- buy additional bits for other tenon thicknesses
  • Mortise-specific -- less versatile than a general spiral plunge bit
