Product Introduction:
A reamer is a type of rotary cutting tool used in metalworking. Precision reamers are designed to enlarge the size of a previously formed hole by a small amount but with a high degree of accuracy to leave smooth sides. There are also non-precision reamers which are used for more basic enlargement of holes or for removing burrs. The process of enlarging the hole is called reaming. There are many different types of reamer and they may be designed for use as a hand tool or in a machine tool, such as a milling machine or drill press. Generally speaking, the geometry of a hole drilled in metal by a twist drill may not be accurate enough. In order to have smooth and accurate surface in a bore, the reamers are used to make the bore meet the high precision and standard requirements. Moreover, most of metals can be machined with a reamer.

Common problems and solutions for reaming:
| Oversized Holes | Reduce Diameter Of Reamer |
| The Center Of Reamer Is Not In Alignment With Hole Center. Adjust The Concentricity Of Hole And Reamer | |
| Radial Run-Out Of Reamer Is Too Large. Good Radial Run-Out Is A Key To Successful Reaming | |
| Scratches On Reamer Shank | |
| When Using Bushing, Ensure Shank Is Clean | |
| Select A Suitable Coolant | |
| Adjust Cutting Parameters | |
| Undersized Holes | Increase Diameter Of Reamer |
| Reduce Rotating Speed | |
| Reduce The Margin Width | |
| Excessive Tool Abrasion, Please Conduct Cutting After Regrinding | |
| Thermal Expansion Coefficient Of Work Piece Is Too Large. Please Keep It Cooled Enough | |
| Short Tool Life | Enhance The Hardness Of Reamer Cutting Edge |
| Select The Reamer Made By Advanced Material | |
| Check The Coolant | |
| Use Surface Treatment For Reamer Such As Nitride Process | |
| Change The Straight Flute To Helical Flute | |
| Check All Factors Affecting Machining Precision |
