RUITOOL Desktop Tapping Arm, 90° Tap Guide Jig for Aluminum Extrusion

Key features

• Straight 90° TappingHelps keep taps square to the workpiece for cleaner, straighter threads. Reduces side load that can lead to crooked holes, stripped threads, or broken taps when tapping aluminum extrusion.
• Made for Aluminum Extrusion BuildsDesigned for end tapping and blind-joint prep on 2020, 2040, 3030, 4040 and 8020-style aluminum profiles. Useful for 3D printer frames, CNC frames, sim racing rigs, workbenches, machine guards, and DIY enclosures.
• Works with Your Hand DrillTurns a standard hand drill into a compact desktop tapping station. The 1/16"-3/8" three-jaw chuck fits common metric and SAE taps from M2-M10 and #2-3/8".
• Clamp-On or Screw-Fixed MountingUse the 0-1.73" C-clamp for quick setup, or screw-fix the base to thicker benches for a more permanent station. Supports vertical tapping on the tabletop and horizontal tapping from the bench side.
• Compact Alternative to a Tapping MachineA practical choice for makers, small shops, and garage workshops that need repeatable tapping accuracy without a bulky industrial tapping machine. Ideal for batch tapping aluminum extrusion during frame assembly.
• PRO-LEVEL TAPPING GUIDELINESFor the cleanest threads and zero broken taps, follow these 4 tips: Hold the drill with both hands for stability. Apply gentle pressure; let the tap cut naturally, never force it. Use tapping fluid to cut friction and wobble. Run at low speed (RPM). Master these for a buttery-smooth cut!
