To obtain the price of a “Special” or “Custom” Aircraft Reamer or Core Drill, you'll need to provide the basic specifications. Take a look at the minimum information required to get a fast, accurate quote on the exact tool you need.
The following variables will determine a reamer's performance. (Please click on bold text for further details.)
Speeds listed below are suggested as a guide only; each set-up may differ, depending upon final application.
- Aluminum
230 SFM - Brass & ordinary brass
165 SFM - Bronze, high tensile
60 SFM - Cast iron, chilled
25 SFM - Cast iron, hard
60 SFM - Cast iron, soft
85 SFM - Magnesium
230 SFM - Monel metal
30 SFM - Plastics
86 SFM - Stainless steel
25 - 30 SFM - Steel, alloy
35 SFM - 300-400 Brinell
