Drill Head Spindle (3D Solid)

Create a professional mechanical engineering technical drawing of a drill head, complete with accurate dimensions. Show the FRONT VIEW, TOP VIEW, SIDE VIEW, and one ISOMETRIC VIEW. Use First Angle Projection and standard engineering drawing conventions. Use the following dimensions: Overall length: 120 mm Overall width: 80 mm Overall height: 100 mm Main cylindrical body diameter: Ø60 mm Main cylindrical body length: 70 mm Front mounting flange diameter: Ø80 mm Flange thickness: 15 mm Central drill shaft diameter: Ø25 mm Drill shaft length: 50 mm Central bore: Ø20 mm Four mounting holes: Ø10 mm Mounting-hole bolt circle diameter: Ø60 mm Distance between opposite mounting holes: 60 mm Keyway width: 8 mm Keyway depth: 4 mm Rear section diameter: Ø50 mm Rear section length: 35 mm Chamfer: 2 × 45° Fillet radius: R3 mm Clearly display every dimension using standard dimension lines, extension lines, arrowheads, centerlines, and diameter symbols (Ø). Make sure the dimensions are consistent between all views and do not overlap the object or each other. Use black lines on a clean white background, no colors, no unnecessary decoration. Include a title block at the bottom with: “DRILL HEAD – ENGINEERING DRAWING”, Scale 1:1, Unit: mm. Make the result look like an actual university mechanical engineering drawing sheet, highly precise, clean, and suitable for a technical drawing assignment.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
