Walter-titex 6618298 Carbide Jobber Drill Bit 0.2050 in

Product Description

The WALTER-TITEX 6618298 is a solid carbide jobber length drill bit engineered for high-performance drilling in demanding production environments. Built to DC150 Series standards, it features a 0.2050-inch cutting diameter, a 140-degree split point, and a TiAlN coating that resists heat and wear during high-speed cutting. The whistle notch straight shank measures 0.2360 inches in diameter and 1.4170 inches in length. Internal coolant-through capability supports chip evacuation and thermal management during deep or blind hole operations. Licensed machinists, tool-and-die shops, and CNC production teams are the primary users of this bit.

This drill bit is suited for blind hole drilling and stack drilling applications across a range of workpiece materials including steel, cast iron, non-ferrous metals, superalloys, and titanium. The 5xD flute-by-diameter ratio and regular spiral flute geometry make it effective in both low and high production settings where consistent hole quality and dimensional accuracy are required. It conforms to ANSI and ISO standards, supporting use in shops with metric or inch-based tooling programs.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• TiAlN coating extends tool life at elevated cutting temperatures
• 140-degree proprietary split point reduces thrust and centers the drill on entry
• Coolant-through design supports chip evacuation in blind hole and stack drilling
• Whistle notch shank provides positive drive retention in compatible toolholders
• Right-hand cut, regular spiral flute geometry for balanced chip flow

Compatibility

Designed for use in CNC machining centers and drill presses equipped with toolholders that accept a 0.2360-inch whistle notch straight shank. Rated for steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces. Conforms to ANSI and ISO dimensional standards.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC setup technicians familiar with carbide tooling. Secure the shank fully in a compatible collet or toolholder before running the spindle; carbide is brittle and sensitive to side-loading from improper clamping. Connect coolant-through supply lines before drilling to prevent thermal shock and premature coating failure. Never exceed the manufacturer-rated maximum drilling depth of 0.6500 inches per pass without retracting to clear chips.
