1–10 mm Tube Drill Guide

Drill perfectly straight holes in round tube

This tube drilling guide is designed to make accurately drilling through round tube quick, repeatable, and easy. It locates on the outside of the tube and provides a straight guide for drill bits from 1 mm to 10 mm.

Ideal for fabrication, motorsport, engineering projects, and general workshop use.

Features:

• Individual guides for 1 mm through 10 mm drill bits

• Helps prevent drills wandering on curved tube surfaces

• Allows more accurate and repeatable hole positioning

• Compact and easy to store

• Fast and simple to print

Print Recommendations:

• Print with the guide hole vertical for the best accuracy

• Use a minimum of 4 walls and 50%+ infill for strength

• PETG, ABS, or nylon recommended for better wear resistance

• Use a slow drilling speed and light pressure to maximise the life of the guide

Notes:

3D printed holes may vary depending on printer calibration and material. The holes are designed with a small clearance to allow standard metric drill bits to fit without additional reaming.

For maximum durability and precision, the design can be modified to accept metal drill bushes.
