▶ The recommendations for speeds, feeds and other parameters presented in this chart are nominal recommendations and should be considered onlyas good starting points. Speed and feed reductions (20% reduction in speed and 10% reduction in feed) are recommended.
▶Recommend you to reduce the feed rate to 85%,70% when you use 5xD,7xD holders.▶ For use of 7xD holder, we recommend to drill a centering pre-hole with equal to or larger than 140 。point angle to min. 2/3 cutting diameter.
The use of the centering pre-hole improves hole location , roundness and surface finish.

▶ The recommendations for speeds, feeds and other parameters presented in this chart are nominal recommendations and should be considered onlyas good starting points. Speed and feed reductions (20% reduction in speed and 10% reduction in feed) are recommended.
▶Recommend you to reduce the feed rate to 85%,70% when you use 5xD,7xD holders.▶ For use of 7xD holder, we recommend to drill a centering pre-hole with equal to or larger than 140 。point angle to min. 2/3 cutting diameter.
The use of the centering pre-hole improves hole location , roundness and surface finish.

ASSEMBLY OF i-DREAM DRILLS
Make sure to clean the insert andinsert seat.
Slide the drill insert into the slot of the holder and press down the insert to touch the bottom of the slot.
After confirming the insert is pressed down to the bottom of the slot,tighten the screw using anti-seize compound.
Use the wing type or T-type wrench.
▶
Need to use appropriate wrenches and screws as indicated.▶
It’s important to tighten up the screw properly.

CAUTION-NOT RECOMMENDABLE APPLICATION
Intersecting cross hole is bigger than the drill insert’sMargin Length.
Material with slanting entrance and exit over 7degree. (If drilling 7 degree or under slanting surface,reduce the feed about 30-50 %)
For drilling stacked plates, minimize the space between the plates.
The space stacked plates can cause insert breakage or poor chip control.
The material needs to be fixtured securelybefore drilling.

RECOMMENDED COOLANT PRESSURE AND FLOW RATE ON VERTICAL DRILLING
TROUBLE SHOOTING
-Recommended emulsion mix is 6% - 8%.
-
For Drilling in Stainless and High Strength steels, a mix of 10% is recommended.
-For horizontal drilling, 30% reduction on the coolant pressure and flow rate is possible.
-Dry drilling is possible for 1-2xD drilling. But not recommended.
1)
Heavy flank wear / Fast flank wear- Reduce cutting speed- Increase feed
2)
Chipping on cutting edge- Reduce feed- Check the rigidity of spindle and chuck- Rigid clamping of workpiece
3)
Build up on cutting edge- Increase cutting speed- Use a coated insert
4)
Chipping or break down on outer corner- Reduce feed- Rigid clamping of workpiece
5)
Wear of land margin- Rigid clamping of workpiece- Reduce cutting speed- Increase coolant flow
6)
Unsatisfactory positioning of the hole- Rigid clamping of workpiece- Reduce feed during entrance or exit
7)
Scratching on holder- Rigid clamping of workpiece- Reduce feed- Increase coolant flow
8)
Unsatisfactory surface finish- Rigid clamping of workpiece- Increase coolant flow and pressure

(1) TiN (Titanium Nitride) coating
Titanium Nitride gives the tool a higher performance in comparison to traditional non-coated drills.TiN coating, with good all-around properties, is recommended for the general application, i.e., attack by abrasive,adhesive and chemical wear in equal proportions.
(2) TiCN (Titanium Carbon Nitride) coating
TiCN coating should be employed when severe thermodynamic stress is expected, for example when drilling inhigh hardened steels or in mild steels with high speed and feed.
(3) TiAlN (Titanium Alumium Nitride) coating
The addition of Aluminum to the Titanium Nitride produces an increase in hardness and an exceptional increase inresistance to oxidation at high temperature.TiAlN coating is applied to drilling with severe thermal stress on cutting edges when continuous non-step feed, drycutting or high speed cutting.
