Multi-Tool System
"D" Series Operating Instructions
With the use auxiliary pilots, holes may be drilled up to 2-1/2"
diameters in steel while maintaining optimum rigidity with low horsepower.
- Step 1 -
Drill first pilot hole with conventional 3/4" twist drill or the
3/4" Multi-Tool pilot drill.
- Step 2 -
- For Finish Hole Over 1-1/2" or less
Insert finish size blade into holder and drill hole to size.
- For Finish Hole Over 1-1/2" to 2"
Insert 1-1/2" blade in piloted holder and enlarge hole to 1-1/2".
Next, insert finish size blade into holder,
attach 1-1/2" auxiliary pilot and drill to size.
- For Finish Hole Over 2"
Insert 1-1/2" blade in piloted holder and enlarge hole to 1-1/2".
Next, insert 2" blade in piloted holder, attach 1-1/2" auxiliary pilot,
and enlarge hole to 2". Finally, insert finish size blade into holder,
attach 2" auxiliary pilot and drill to size.
- Note:
When drilling certain non-ferrous metals, it may be possible to drill
up to a 2-1/2" hole in one pass without the use of one or both auxiliary
pilots.
- Cutting fluids are always required when machining
metals (except for cast iron) for safe operation and longer tool life.
Select the appropriate fluid for the material to be machined.
