Note: Always start with conservative parameters and adjust based on tool performance and chip formation.

Step-by-Step Guide: How to Drill Through Titanium Bar Properly

Step 1: Mark and Secure the Workpiece

• Use a center punch to mark the drilling spot.

• Clamp the titanium bar securely to prevent movement or vibration.

Step 2: Use a Pilot Hole

• Start with a small pilot hole (e.g., 2 mm) to guide the larger drill bit.

• This reduces heat and improves accuracy.

Step 3: Apply Lubrication Generously

• Use cutting fluid continuously throughout the operation.

• Reapply if using hand tools or pause drilling to add lubricant.

Step 4: Drill at a Consistent Feed Rate

• Avoid peck drilling (frequent stopping and starting), which generates heat.

• Maintain steady pressure to break chips cleanly and avoid work hardening.

Step 5: Use the Right Speed

• Slower spindle speeds with higher torque are better for titanium.

• Adjust as necessary if you notice squealing or smoke—signs of excessive heat.

Step 6: Inspect the Hole and Tool

• Check the hole for burrs, roughness, or burn marks.

• Ensure the drill bit is not dull or discolored.

Common Mistakes to Avoid

1. Running at high RPMs – Causes overheating and tool wear.

2. Skipping lubrication – Leads to galling and poor surface finish.

3. Using cheap drill bits – They dull quickly and may snap mid-process.

4. Drilling too fast – Causes surface hardening that ruins subsequent passes.

5. Insufficient clamping – Creates vibration that damages the hole and tool.

sakyalloy recommends testing your parameters on sample material if this is your first time drilling titanium.

Post-Drilling Finishing

After drilling, it may be necessary to:

• Deburr the edges with a countersink or deburring tool.

• Inspect with bore gauges or calipers for accuracy.

• Clean off residue with alcohol to remove oil and chips.

• Passivate the surface if required for medical or marine applications.

Drilling Titanium in CNC Machining

For high-volume or tight-tolerance applications, CNC drilling offers:

• Consistent feed and speed control

• High-precision hole placement

• Integrated coolant delivery

Make sure the program includes chip break cycles, entry/exit dwell, and low spindle RPMs for titanium.

Safety Precautions

• Wear eye protection, gloves, and a mask if misting coolant.

• Use slow and controlled motions to avoid sudden torque kickback.

• Maintain a clean workspace—titanium chips are sharp and can be hot.
