Introduction

Mortise bits create precise square or rectangular holes in wood when paired with a mortiser or drill press.

  • Choose a bit size that matches the mortise width needed for your joinery.
  • Check the shank diameter to ensure compatibility with your drill press or mortiser collet.
  • Look for carbide-tipped edges to maintain sharpness through multiple hardwood projects.

FAQs

Hardwoods like oak, maple, and walnut produce clean mortises when the bit is sharp and feed rate is steady.

Most mortise bits require the stability of a drill press or dedicated mortiser to keep the cut square and controlled.

Clean resin buildup after each use and hone the cutting edges with a fine diamond file to restore performance.

Set the depth stop so the bit reaches the full mortise length plus a small clearance for glue squeeze-out.

Standard bits are right-hand; left-hand versions exist for specialized machines that rotate counterclockwise.
