YG-1 says the coating advances and optimized designs of its i-One system of exchangeable micro-grain carbide drill inserts and premium tool steel holders with coolant channels improve tool life and changeover speed.

“Our new i-One line offers the advantage of a solid carbide drill combined with the flexibility of steel bodies,” says Steve Pilger, YG-1’s Holemaking product manager. “i-One micro-grain carbide inserts combine a new, multilayered H-coating and optimized cutting angles with tool steel holders with Torx Plus clamping stability.

With those and other advanced features, i-ONE drills last longer than competitors’ products,” he continues. “And when you finally need to change inserts, we engineered the i-ONE interface for foolproof and worry-free insert changeovers.”

i-One drill inserts feature micro-grain carbide cores to improve strength, an advanced multilayered H-coating that achieves what the company says is excellent hot hardness and minimal wear, ground negative land on the cutting edge for extended cutting life and point geometry optimized for centering and smoother cutting.

The system’s nickel-plated tool steel holder is optimized to resist corrosion and wear while ensuring body clearance. Other features include a flute shape optimized for smooth chip evacuation, a Torx Plus Screw for reliable insert seating and stability at the full range of speeds and coolant holes to assist in dissipating heat and evacuating chips from the cutting zone.

YG-1’s i-ONE drills come in various insert sizes from 0.393” to 1.328” (10 to 33.73 mm), and the tool steel holders are available at depths 3, 5 and 8 times the diameter.
