Description
The Proxxon Tungsten Vanadium Micro Twist Drills (No. 28856) are a 3-pack of ×1.2mm (3/64") precision micro twist drills for Proxxon Micromot tools, on 2.35mm shanks. Manufactured from one-piece blanks in tungsten vanadium steel for highest concentricity — the single-blank construction eliminates the joint between drill tip and shank, providing breakage safety and long service life at fine micro drill diameters.
For drilling metal, non-ferrous metals, plastics, and wood. Speed guidance: approximately 8,000 RPM for soft materials, approximately 3,000 RPM for hard materials.
Key Features
- ×1.2mm diameter — mid-range micro drill; precision holes with a good balance of fineness and breakage tolerance
- One-piece blank construction — highest concentricity; breakage safety and long life at fine diameters
- Tungsten vanadium steel — for metal, NF metals, plastics, and wood
- 2.35mm shank — fits standard Micromot collets and keyless chucks
- 3-pack — spares included; useful at fine diameters where breakage can occur
Speed Guide

TV Micro Twist Drill Diameter Guide
- ×0.5mm (No. 28864) — absolute finest; 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
- ×1.2mm / No. 28856 (this drill) — mid-range; balanced fineness and breakage tolerance for general micro drilling
- ×1.6mm (No. 28858) — largest micro drill; wider precision holes with lowest breakage risk in the range
