Walter-titex 6618709 Solid Carbide Jobber Drill 10.70 Mm

Product Description

The WALTER-TITEX 6618709 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding production environments. It features a 10.70 mm (0.4213 inch) cutting diameter, a 140-degree split point, and a TiNAl (titanium aluminum nitride) coating that extends tool life under heat and abrasion. The overall length is 163.00 mm (6.417 inches) with a 114.00 mm (4.488 inch) flute length and an 8xD flute-to-diameter ratio, allowing for deeper penetration in a single pass. The straight-cylindrical shank measures 12.00 mm (0.472 inch) in diameter and 45.00 mm (1.772 inches) in length. This drill is right-hand cutting and is sized to a m7 diameter tolerance, making it suitable for precision-fit applications. It is installed by machinists and tool-and-die professionals.

The 6618709 is built for drilling into cast iron, non-ferrous metals, steel, superalloys, and titanium. It supports blind hole and stack drilling applications, making it a practical choice for aerospace, automotive, and general machining operations where multiple material types or part stacking are common. Coolant-through capability allows cutting fluid to be delivered directly to the cutting zone, improving chip evacuation and tool life at depth. Maximum drilling depth is rated at 96.00 mm (3.780 inches). The DC150-08-A1 series designation identifies the product family within the WALTER-TITEX solid carbide drill lineup.

Key Features

• Solid carbide construction in grade WJ30TA for rigidity and wear resistance in hard and abrasive materials
• TiNAl coating reduces heat buildup and extends cutting edge life in ferrous and high-temp alloy applications
• 140-degree point angle promotes self-centering entry and reduces thrust in hard materials
• Coolant-through design delivers cutting fluid directly to the cutting zone for improved chip removal at depth
• 8xD flute ratio supports deep-hole drilling up to 96.00 mm without peck cycles in suitable setups
• Meets ANSI and ISO standards; m7 shank tolerance ensures consistent tool-holder fit

Compatibility

Designed for use in CNC machining centers and drill presses accepting a 12.00 mm straight-cylindrical shank. Suitable for workpiece materials including cast iron, non-ferrous metals, steel, superalloys, and titanium per primary workpiece material codes K, N, P, and S. Part of the WALTER-TITEX DC150-08-A1 series, covering drill sizes in the 10.00 mm to 12.50 mm diameter range.

Installation Notes

Installation and use should be performed by qualified machinists familiar with CNC tooling and cutting parameters. Secure the straight-cylindrical shank in a compatible collet or drill chuck rated for the shank diameter before operation. Verify coolant-through passages are clear and that the machine spindle delivers adequate coolant pressure before engaging deep-hole cycles. Do not exceed the rated maximum drilling depth of 96.00 mm without consulting the manufacturer cutting data.
