HSS TWIST DRILL BITS FOR NON-FERROUS METALS, PLASTICS AND WOOD PROXXON ROTARY TOOLS

HSS Precision for Model Making and Fine Mechanics

The Proxxon HSS twist drill bits are designed to ensure clean, controlled drilling in precision work. The cutting geometry is inspired by the DIN 338 standard, ensuring smooth feed and good stability even in the most delicate applications on soft materials.

Main Technical Features

• Material: High quality HSS high speed steel, ideal for drilling non-ferrous metals, plastics and wood.
• Accurate sharpening: ensures smooth hole starting and good concentricity during rotation.
• Micromot Compatibility: Designed to work best with Proxxon rotary tools, both corded and cordless.
• Precision construction: tight tolerances and good elasticity make these tips suitable for model making, electronics and fine mechanics.

Directions for Use

To maximize cutting edge life, we recommend using a light lubricant when drilling non-ferrous metals (e.g., petroleum or alcohol for aluminum). Wood and plastics can be machined dry. We also recommend using MICROMOT steel collets to ensure optimal concentricity.
