Technical Specifications ( Tanner Spec Pages )
| Material | Surface Feet / Minute (SFM) | Sample Calculations for 1/4” Countersink Speed (RPM) |
|---|---|---|
| Aluminum | 200 - 250 | (225 (SFM) x 3.82 / .2500) / 3 = 1,146 RPM |
| Mild Steel | 100 - 110 | (115 (SFM) x 3.82 / .2500) / 3 = 586 RPM |
| Stainless Steel | 30 - 100 | (65 (SFM) x 3.82 / .2500) / 3 = 381 RPM |
How to Choose The Right Size Countersink by Diameter
- A simple rule of thumb is to choose a countersink which is 50% larger than the diameter of the hole
- Countersink diameter = 1.5 x bolt size (hole) diameter
- Ex: For a 1/4-20 bolt, multiply the diameter (.250) x 1.5 = .375. This equates to a 3/8” countersink
How to Choose The Right Size Countersink by Angle
- Angle is based on the screw or bolt type being used
- 82º is most common
