Reamers are "finishing" tools used to "ream" a hole
previously drilled in order to create a good finish or achieve
an accurate diameter, within the required tolerance of up to
0.001 mm. (1 micron).
Reamers are end-types cutting tools, cutting only on the
chamfer's edge at the outside diameter of the preformed hole.
The standard 45° chamfer angle provides effective cutting
action for most materials.
Carbide Reamers. For general purpose
non-critical finishing of metal parts.
Precision Diamond (PCD) Reamers. For high
precision and close tolerance finishing of automotive engine
parts, miniature parts, electronic parts and related products.
PCD Reamers are excellent in large production runs due to its
high resistant to wear and capacbility to machine at high
Coolant Fed. Exceptional performance and tool
life using material specific reamer technology and coolant fed
capabilities; maximizes feeds & speeds.

The most common types of reamers are Hand, Machine,
Chucking Reamers and other types of reamers with different
cutting profiles for various reaming operation.
Reamers can be used manually or by CNC Drilling
