WC-Type U-Drills
WC-Type U-Drills are designed for high-efficiency hole making with indexable inserts, delivering excellent chip evacuation and stability. Ideal for CNC machining, they reduce downtime and improve productivity across various materials.
Double helix internal cooling keeps temperatures in check. Runs stable. Center and peripheral edges share the load evenly. Holes come out clean.
Innovative spiral flutes with a 6:4 inner/outer ratio. Chips evacuate smooth, rarely clog.
Nickel-plated surface. Resists rust, oil, and corrosion. Stays clean in storage, lasts longer.

Double helix internal cooling. Coolant hits the cutting zone directly. Temperature stays down, tool stays true.
Continuous cooling flow. Cuts heat, extends insert life.
Center and peripheral edges balance the cutting load. Stable forces, precise holes.

Minimal vibration. Good wall finish, less scrap.
Innovative spiral flute design. Inner/outer ratio at 6:4. Plenty of chip room, smooth flow.
Groove structure guides chips out directional. No clogging, no breakage from packed chips.
Optimized flute ratio cuts resistance. Better chip evacuation, good for high-feed work.
High-strength alloy steel body. Rigid and tough. Won't deform or snap under heavy cuts.
Standard insert mounting. Swap inserts fast, no regrinding. Saves tool change time.
Fits multiple standard insert types. This Indexable U Drill Bit is versatile, keeps inventory simple.
Precision positioning. Inserts locate accurately. Concentricity is tight, holes land on target.
High-rigidity holder structure. Good impact and vibration resistance. No chatter marks even at speed.

Works across materials. This WC Type U Drill handles carbon steel, stainless, and cast iron.
One-pass drilling. No pilot hole, no centering. Faster cycle times.
Stable chip evacuation and cooling even in deep holes. Fewer pecks, better continuity.
Optimized coolant path. Flow is sufficient, cooling is even. No hot spots.
Nickel-plated surface is smooth and wear-resistant. No built-up edge, no scratching the work.
High surface finish. Chips don't stick. Easy cleanup, longer tool life.
Dynamically balanced. Runs smooth at high RPM. Easier on the machine, quieter.
Fits CNC lathes and machining centers. This WC Type Indexable U Drill Bit is built for batch work.
Stable performance. Less downtime from tool failures. More uptime.
Cost-effective design. Holder is reusable, just swap inserts. This Indexable U Drill WC saves money long-term.
