Walter-titex 6618411 Solid Carbide Jobber Drill Bit

Product Description

The WALTER-TITEX 6618411 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built to Series DC150 specifications, it features a 0.469-inch diameter cutting edge with a TiAlN coating that extends tool life when cutting through abrasive and high-strength materials. The 140-degree split point reduces thrust and improves centering without a pilot hole. With an overall length of 4.646 inches and a right-hand spiral flute, this bit is suited for production environments where consistent hole quality and tool longevity are required. A licensed machinist or tooling technician is the typical end user.

This drill bit is engineered for use in blind hole and stack drilling operations. It performs across a range of workpiece materials including cast iron, non-ferrous metals, steel, superalloys, and titanium. The coolant-through design supports high-speed machining setups where internal coolant delivery is available. The whistle notch shank provides a positive grip in compatible toolholders, reducing slippage under load. It is well suited for CNC machining centers and manual drill press setups that require accurate, repeatable results in production or repair environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating improves heat resistance and extends service life in ferrous and exotic alloy cutting
• 140-degree point angle reduces walking and improves entry accuracy without center drilling
• Coolant-through design supports internal coolant delivery for deep or high-speed drilling
• Whistle notch shank provides a secure, slip-resistant connection in compatible toolholders
• Right-hand spiral flute with 5xD flute-to-diameter ratio supports efficient chip evacuation in blind hole applications

Compatibility

The 6618411 is a DC150 Series drill bit rated for cast iron, non-ferrous metals, steel, superalloys, and titanium workpieces. It is compatible with toolholders accepting a 0.472-inch whistle notch shank. Conforms to ANSI and ISO standards.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Before mounting, confirm the toolholder is clean and that the whistle notch is properly aligned with the drive flat. Power down and lock out the machine before changing tooling. Verify spindle speed and feed rate against the manufacturer tooling guide for the specific workpiece material before beginning operation.
