Walter-titex 6618699 Solid Carbide Jobber Drill 9.80 Mm

Product Description

The WALTER-TITEX 6618699 is a solid carbide jobber drill engineered for high-performance drilling in demanding industrial and trade applications. Built to Series DC150-08-A1 standards, it features a 9.80 mm diameter cutting edge, a 140-degree split-point geometry, and a TiNAl (titanium aluminum nitride) coating that extends tool life under elevated cutting temperatures. The straight-cylindrical shank measures 10.00 mm in diameter and 40.00 mm in length, seating securely in standard toolholders. With a flute-to-diameter ratio of 8xD and coolant-through capability, this drill is designed for consistent chip evacuation and thermal management in deep hole work. It is installed and used by machinists, tool-and-die professionals, and maintenance technicians running CNC or manual drilling operations.

This jobber drill is rated for use in cast iron, non-ferrous metals, steel, superalloys, and titanium — material codes K, N, P, and S. Typical applications include blind hole drilling and stack drilling where point accuracy and edge retention are critical. The 140-degree point angle reduces thrust force on entry and exit, which is particularly valuable when drilling layered or interrupted workpieces. An overall length of 139.00 mm and a flute length of 95.00 mm support reach requirements common in structural and component drilling setups. The drill meets both ANSI and ISO standards, confirming dimensional and performance conformance across tooling systems.

Key Features

• Solid carbide construction, grade WJ30TA, for rigidity and edge retention in hard and abrasive materials
• TiNAl coating improves wear resistance and oxidation resistance at elevated cutting speeds
• 140-degree point angle reduces entry thrust and improves positional accuracy
• Coolant-through design supports chip evacuation and thermal control in blind hole applications
• 8xD flute-to-diameter ratio enables drilling depths up to 80.00 mm
• Straight-cylindrical shank compatible with standard collet chucks and drill chucks
• Two-flute geometry optimized for blind hole and stack drilling scenarios

Compatibility

Designed for use in CNC machining centers, drill presses, and manual machines equipped with toolholders accepting a 10.00 mm straight-cylindrical shank. Suitable for workpiece materials including cast iron, non-ferrous metals, carbon and alloy steels, superalloys, and titanium. Conforms to ANSI and ISO dimensional standards. Part of the WALTER-TITEX DC150-08-A1 series, covering drill diameters in the 9.00 mm to 10.00 mm range.

Installation Notes

Installation and use of this drill should be performed by qualified machinists or toolroom technicians familiar with carbide tooling handling procedures. Power down and de-energize the machine spindle before mounting or removing the drill. Seat the straight-cylindrical shank fully in the collet or chuck and verify runout before initiating a cut. Carbide tooling is brittle — avoid side loading, interrupted feeds without proper parameters, or dropping the tool on hard surfaces.
