Speed - Feed For Koolream Reamers CJT Koolcarb Catalog Solid Carbide Non-Coolant Fed Drills


Chucking Reamers
Reamers 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		Stock Removal
Excessive speed will cause chatter and poor finish.		Insufficient stock removal will result in burnishing and will cause premature wear.

Proper Feed		Proper Set Up
Insufficient feed will cause glazing and excessive wear. Excessive feed will reduce accuracy and the quality of the finish.		Reamers should have a minimum overhang and be run through a bushing whenever possible, with a heavy flow of lubricant.
