Micro Drilling and Punching Systems


Minitool Micro Drilling Systems
General Information
Minitool's patented micro drilling machines represent a completely new and innovated approach to precision micro drilling.  Super hard in-line interchangeable vee bearings replace the conventional ball or sleeve bearings.  The drills are mounted within an interchangeable drive pulley and held against the vee bearing by means of a special endless drive belt.  The drill now becomes its own spindle, eliminating the runout that is a common factor in conventional machines using ball bearings, sleeve bearings, spindles, collets or chucks.

Minitool, Inc., manufactures manual as well as CNC-controled (automatic) micro drilling systems.

Drills, endmills and special tooling are also manufactured by Minitool, Inc., using our proprietary tool grinding technique.

Minitool's patented interchangeable vee-bearing design is typical on all micro drilling machine models.  It eliminates all chucking errors.

Our .05mm (.0019”) spiral HSS microdrill has been especially designed for the smallest diameter microdrilling with excellent chip clearing properties.

The 1-254 HSS microdrill line includes this remarkable tool in addition to drills in diameters to .50mm (.020”) diameter in increments of .01mm. (.0004”).  Flute lengths 7-10x tip diameter.

Drills in this micro range require the ultimate in microdrilling equipment that assures minimum drill run out.  Ordinary microdrilling machines employing collets or chucks cannot assure this.  It is for this reason that Minitool has developed a special microdrilling machinewhere precision micro drills, such as the 1-254 series, are held in special vee bearings virtually eliminating drill runout. Our Model L microdrilling machine is simply designed, easy to use, provides, for manual microdrill depth settings, is very economical and highly recommended for use with the 1-254 series drills.

Minitool Punching Machines

When punching and blanking to .10mm (.0039”) or smaller, conventional punch and die methods can no longer be applied.  Minitool, Inc. has developed a special kind of tooling for their micro punch presses designed expressly for punching holes in the micro range.

All Minitool micro punch presses are designed and manufactured with features not found on other small punch presses.

  • Adjustable punch and die button alignment capabilities rule out any alignment problems caused by lock screws, set screws, etc.
  • Preloading of press spindles to eliminate any play assures absolute repeatability.
  • Special alloy casting material with all moving and wear parts hardened and ground steel.
  • Micro presses are lightweight, portable and have mounting holes.

Optional Features:  

  • Preloading of spindle for 150TK and 200TK presses (standard on 60HP).
  • Larger diameter cylinder and longer stroke for 150AP presses.
  • Stereo microscope especially developed for micro punching.
