Exchangeable Drills and Tool Steel Holders For Faster Changeovers, Longer Insert life

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 for maximized machining productivity and profitability.

According to Steve Pilger, product manager, Holemaking, the i-ONE line offers the advantage of a solid carbide drill combined with the flexibility of steel bodies via inserts that combine a new multilayered H-coating and optimized cutting angles with tool steel holders that retain Torx Plus clamping stability. These attributes and more, says Pilger, ensure i-ONE drills last longer, and that the insert changeover process has been made foolproof and worry-free. 

i-ONE drill inserts offer additional advancements 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

i-ONE drills come in various insert sizes, and tool steel holders are available in 3xD, 5xD and 8xD depths and in ODs from 0.393 in. to 1.328 in. and Ø10 mm to Ø33.73 mm.
