Coating advances and optimized designs take tool life and changeover speed to new highs with YG-1’s new i-ONE system of exchangeable micro-grain carbide drill inserts and premium tool steel holders with coolant channels, the company recently announced.
“Our new i-ONE line offers the advantage of a solid carbide drill combined with the flexibility of steel bodies,” said Steve Pilger, Product Manager, Holemaking. “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. And when you finally need to change inserts, we engineered the i-ONE interface for foolproof and worry-free insert changeovers. It’s just a great system.” (See attached for test data.)
i-ONE drill inserts feature the latest YG-1 technological advances, including:
- Micro-grain carbide core for exceptional strength
- Advanced multilayered H-coating for excellent hot hardness, minimal wear
- Optimized point geometry for centering and smoother cutting
- Ground negative land on cutting edge for extended cutting life
The system’s nickel-plated tool steel holder features:
- Premium tool steel shaft optimized to resist corrosion and wear and ensure body clearance
- Optimized flute shape for smooth chip evacuation
- Torx Plus® Screw for reliable insert seating and stability at the full range of speeds
- Coolant holes to dissipate heat in and evacuate chips from the cutting zone
The i-ONE system is the latest development from YG-1 engineers to help customers maximize machining productivity and profitability. i-ONE drills come in various insert sizes, and tool steel holders are available in 3xD, 5xD and 8xD depths and in ODs from.393 in. to 1.328 in. and Ø10mm to Ø33.73mm.

1. Process of locating the center of a workpiece to be mounted on centers. 2. Process of mounting the workpiece concentric to the machine spindle. See centers.
Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
Part of the tool body that remains after the flutes are cut.
