Compare Guhring solid-carbide drilling configurations
Compare RT 100 U series 5514 with external coolant and RT 100 XF series 6498 and 5498 with internal coolant. This selection separates 3xD and 5xD configurations and preserves Guhring’s exact diameter and order references.
Set the hole requirement first
Confirm diameter, depth, tolerance, workpiece material, entry and exit conditions. Review the selected EDP’s drilling depth and working dimensions; a depth ratio alone does not establish a machining cycle.
Match coolant and toolholding
Series 5514 uses external coolant. RT 100 XF series 6498 and 5498 provide internal coolant delivery. Check machine and holder capability, shank dimensions and usable tool length before choosing the configuration.
Keep reference sizes distinct from order identity
Some manufacturer records include fractional or wire/letter references alongside metric nominal dimensions. These references describe the same EDP, not interchangeable duplicate products. Use the exact EDP and selected dimensions when requesting a quote.
