Deep-Hole Drilling With Efficient Chip Evacuation
Guhring’s RT 100 T series spiral-flute, deep-hole drills are capable of drilling to 20, 25 or 30 × D. According to the company, the solid carbide, coolant-fed drills enable high feeds and speeds.
The drills feature a flute geometry designed to improve chip evacuation. A large coolant-duct profile provides coolant to the cutting edge for lubrication and cooling. The drills are also equipped with polished flutes to aid chip flow, while Super-A coated tips protect against abrasive materials to prolong tool life, the company says. The drills are available in diameters ranging from 3.5 to 8 mm, with 20-mm-diameter drills available on request.
