Axis Micro Drills by Series
Six series: two coatings, three flute lengths. Every drill has a 3mm shank, so one holder takes the whole range. Overall length steps up with diameter.
| Series | Coating | Flute length | Diameter | Overall length | Shop |

| T3011 | Uncoated | Short (3 – 5xD) | 0.30 – 3.00 mm | 38 mm | 271 sizes |
| T3021 | Uncoated | Medium (5 – 8xD) | 0.10 – 3.00 mm | 38 / 45 mm | 291 sizes |
| T3031 | Uncoated | Long (8 – 12xD) | 0.015 – 3.00 mm | 38 / 45 / 50 mm | 300 sizes |
| T3110 | Axicoat | Short (3 – 5xD) | 0.30 – 3.00 mm | 38 mm | 271 sizes |
| T3120 | Axicoat | Medium (5 – 8xD) | 0.30 – 3.00 mm | 38 / 45 mm | 271 sizes |

Choosing a micro drill
Choose an Axis Micro Drill in Four Steps
Use the shortest drill that reaches the depth: it is stiffer, so it holds size and position better.
- 1
Diameter
Every size from 0.30 to 3.00mm comes in 0.01mm steps. Below 0.30mm, use the uncoated medium or long series.
- 2
Depth
Divide the hole depth by the diameter. Up to about 5xD use a short drill; deeper holes need medium or long.
- 3
Material
Uncoated for steels, stainless, cast iron, non-ferrous and plastics. Axicoat for high-alloy steels, titanium and nickel alloys.
- 4
Start the Hole
For deep holes, start with a short drill of the same diameter, then follow with the longer drill.
Questions
Axis Micro Drills: Common Questions
What does 3 – 5xD mean?
It is the flute length as a multiple of the drill diameter. A 1mm drill in the 3 – 5xD short series has a flute about 3 to 5mm long, so it drills holes up to about that depth. Medium drills cover 5 – 8xD and long drills 8 – 12xD.
Uncoated or Axicoat: which should I choose?
Uncoated drills suit low and unalloyed steels, stainless steel, cast iron, non-ferrous metals and plastics. Axicoat drills cover the same materials and add high-alloy steels, titanium and nickel alloys, with less friction and better chip flow.
What is the smallest Axis drill?
The uncoated long series T3031 starts at 0.015mm, and the uncoated medium series T3021 at 0.10mm. All the other series start at 0.30mm. Every series goes up to 3.00mm.
What shank do Axis micro drills have?
Every Axis micro drill has a 3mm shank, whatever the cutting diameter, so one collet or holder takes the whole range.
How do I drill a deep micro hole?
Start the hole with a short drill of the same diameter, then follow with the medium or long drill. The short drill is stiffer, so it starts the hole in the right place and the longer drill follows it straight.
Not Sure Which Micro Drill You Need?
Send us the hole diameter, the depth and the material, and we will match the Axis series and size. Everything here ships from Kent.
