Speed / Feed For Durapoint® Reamers

 

Chucking Reamers

 
Reaers made to a tolerance other than standard (+.0003"_.0000"), within the decimal range shown in decimal size range column,
may be priced using standard list price of
closer fractional size plus the add on per piece as shown in the Price List. 		               Semi-standards or decimal sizes within decimal size range shown are understood to have the exact same specifications (overall, flute length, shank configuration, number of flutes, etc.) as the closest fractional size within this range.
 

Important Factors in Reaming Operations

 
Proper Speed

Excessive speed will cause chatter and poor finish.

Proper Feed

Insufficient feed will cause glazing and excessive wear. Excessive feed will reduce accuracy and the quality of the finish.

Stock Removal

Insufficient stock removal will result in burnishing and will cause premature wear.

Proper Set Up

Reamers should have a minimum overhang and be run through a bushing whenever possible, with a heavy flow of lubricant.
