Peck Drilling (Deep Hole)	✓✓✓ Optimal	1.5–2×D peck depth; full retract for chip break
Step Drilling	✓✓ Good	Reduce speed 10% at step transition
Chamfering / Spotting	✓✓ Good	Use reduced spindle speed; light depth
Enlarging / Reaming	✓ Limited	Not recommended; use dedicated reamer
Trepanning	✗ Not Suitable	Tool geometry not designed for trepanning

9. Recommended Cutting Conditions

Low-Carbon Steel (C < 0.25%)	40–60	0.10–0.18	5415–8303
Medium-Carbon Steel (0.25–0.55%)	30–50	0.08–0.15	4151–6859

Note: RPM values are calculated for 2,77 mm diameter. Actual spindle speeds should be adjusted based on machine capability, rigidity, and coolant conditions. Always start at the lower end of the range and optimize based on chip formation and sound.

10. Operating Guidelines

Runout Tolerance: Maintain TIR (Total Indicator Reading) below 0.01 mm at the tool tip. Excessive runout causes uneven wear and premature failure.
Coolant Recommendation: Flood coolant with 5–8% emulsion concentration is recommended for steel and stainless steel. For aluminum, air blast or MQL (Minimum Quantity Lubrication) is often sufficient.
Peck Cycle: For holes deeper than 3×D, implement a peck drilling cycle with 1.5–2×D peck depth and full retract to break chips.
Entry Angle: Ensure perpendicular entry (90° ± 0.5°) to the workpiece surface. Use a center drill or spot drill for irregular surfaces.
Tool Overhang: Minimize tool overhang to 4×D or less. Use collet chucks or hydraulic chucks for best gripping force and damping.
Chip Evacuation: Verify adequate coolant pressure (minimum 10 bar for deep holes) to flush chips from the cutting zone.
Edge Inspection: Inspect cutting edges under magnification (20×) after every 50 holes in abrasive materials. Replace at first sign of flank wear exceeding 0.15 mm.
Storage: Store in original packaging away from humidity and temperature extremes. Avoid contact between cutting edges and hard surfaces.

11. Toolholder Compatibility

Holder Type	Compatibility	Recommended Application
ER Collet Chuck (ER16–ER32)	✓✓✓ Excellent	General purpose; ensure correct collet size
Hydraulic Expansion Chuck	✓✓✓ Excellent	High-precision finishing; best TIR control
Shrink Fit Holder	✓✓✓ Excellent	High-speed machining; maximum rigidity
Milling Chuck (Power Chuck)	✓✓ Good	Heavy-duty interrupted cuts
Drill Chuck (Keyless / Keyed)	✓✓ Good	Manual machines; lower speed applications
Weldon Side-Lock Holder	✗ Not Compatible	Tool has cylindrical shank; no Weldon flat
