Hot Q&A
Q1: How does internal coolant improve drilling efficiency?
A: Direct coolant flow lowers cutting temperature, prevents chip clogging, allows faster & deeper cuts without damaging the tool.
Q2: Can this drill replace HSS drills?
A: Carbide drills excel in hardness & heat resistance. HSS may be more cost-effective for soft materials & low-volume jobs.
Q3: How to extend tool life?
A: Use compatible coolant, avoid excessive feed pressure, inspect for chipping & coolant channel blockages regularly.
Q4: Do you accept custom orders?
A: Yes, we provide custom diameter, length, coating & non-standard drills per drawing.
