Description
The Proxxon Tungsten Vanadium Micro Twist Drills (No. 28864) are a 3-pack of ×0.5mm (1/64") precision micro twist drills for Proxxon Micromot tools, on 2.35mm shanks. The absolute finest diameter in the TV micro drill range — at 0.5mm, this is an ultra-precision drill where breakage risk is at its maximum. The one-piece blank construction in tungsten vanadium steel is essential at this diameter: the single-blank eliminates the joint between tip and shank, providing the concentricity and structural integrity needed to drill at 0.5mm without immediate breakage.
For drilling metal, non-ferrous metals, plastics, and wood. At 0.5mm, technique is as important as tooling — use a drill stand for perpendicularity, apply minimal pressure, and run at the correct speed. Speed guidance: approximately 8,000 RPM for soft materials, approximately 3,000 RPM for hard materials.
Key Features
- ×0.5mm ultra-precision diameter — absolute finest TV micro drill; for the smallest possible precision holes
- One-piece blank construction — maximum concentricity and structural integrity; essential at 0.5mm
- Tungsten vanadium steel — for metal, NF metals, plastics, and wood
- 2.35mm shank — fits standard Micromot collets and keyless chucks
- 3-pack — spares critical at 0.5mm where breakage risk is highest
Speed Guide
- Soft materials (wood, plastics): approx. 8,000 RPM
- Hard materials (steel, NF metals): approx. 3,000 RPM
- Technique tip: Use a drill stand, apply minimal pressure, and let the drill do the work — forcing a 0.5mm drill causes immediate breakage

TV Micro Twist Drill Diameter Guide
- ×0.5mm / No. 28864 (this drill) — absolute finest; ultra-precision holes, maximum breakage risk — use drill stand and minimal pressure
- ×0.8mm (No. 28852) — very fine; ultra-fine holes with slightly more breakage tolerance
- ×1.0mm (No. 28854) — fine; precision holes with good breakage tolerance
- ×1.6mm (No. 28858) — larger micro drill for wider precision holes
Works Well With
- Professional Rotary Tool IBS/E (No. 38481) — collet-based 100W Micromot tool; use with 2.35mm collet
- Precision Rotary Tool FBS 115/E (No. 38472) — keyless chuck Micromot tool accepting 2.35mm shank
- MICROMOT Steel Collet Set — 6-Piece (No. 28940) — includes 2.35mm collet for this drill
- Drill Stand MB 200 (No. 28600) — essential at 0.5mm — perpendicularity and controlled depth prevent breakage
- Modeler's Set — 13-Piece (No. 28910) — comprehensive accessory set including drilling, milling, and grinding bits
