Micro Reamers
Helical, straight-flute, step and taper reamers from 0.1 mm, including left-hand and combined drill-reamer geometries. Where the bore tolerance matters more than the hole it started as.

Four things we need from you.
Diameter
Nominal bore diameter in mm — the diameter you are holding to tolerance.
Diameter range
The range the geometry ships in.
Flute form
Helical, straight or step. Helical for chip evacuation, straight for a finer surface.
Coating
Black oxide, bronze, DLC or uncoated.
Matched applications.
Pilot holes to tolerance
Taking a drilled hole to a specified size without a second machining operation.
Thin section
Bores in wall thickness where a standard reamer would chatter or deflect.
Left-hand bores
Holes requiring a left-hand cut against the workpiece feed.
