Precision 30mm hinge drill bit for clean plywood joints
✔️ 5/16 parallel shank carbide tip ptfe coat right hand rotation

This single hinge boring bit drops straight into your drill press to cut dead accurate thirty millimeter holes for cabinet doors. You will typically mount it inside a handheld router or lathe stand to handle medium density panels and laminated plywood without tearing the face.

✅ Two precision ground cutting blades paired with negative spurs for chip free entry
✅ Super strength steel body wrapped in a black ptfe layer to stop resin buildup
✅ Micro grain carbide tips with a balanced center pin for steady guidance
✅ Downcut grinding pattern that pushes sawdust down while you work

💡 What makes a handy hinge boring bit perform better than basic step drills?

A dedicated carbide plunge bore tool clears softwood and laminate cleanly because the downcut geometry forces chips downward instead of blowing them out.

- Extra fine micro grain alloy resists heat when you push through 30 mm 1.2 inch mdf layers

- PTFE nonstick finish reduces friction so your motor works less on tough cuts

- Straight 5/16 inch 8 mm profile locks tight into any standard bench grinder chuck
