Offset Drill Guide (6mm hole) 10 degree angle + steel insert

thingiverse

This is a precision drill guide designed to accurately create 6mm holes at a precise 10-degree angle, with a deliberate offset from the work piece's edge. A strategically placed clearance hole accommodates a steel insert that can be bonded in place using epoxy, effectively prolonging the life of the guide as drill bits inevitably wear away plastic over time. The recommended size for mild steel tubing (which can be easily cut to size with a hacksaw) is 10mm outer diameter, 2mm wall thickness, and 6mm inner diameter. Mild steel tubing in this precise size range can be sourced from reputable suppliers such as eBay UK, offering a variety of sizes and lengths. The guide's opposite side features carefully designed channels to allow for the efficient egress of drilled material, ensuring smooth operation during drilling tasks.
