Walter-titex 6712877 Carbide Drill Bit 2 Mm Alcrn

Product Description

The WALTER-TITEX 6712877 is a solid carbide jobber length drill bit engineered for precision drilling in demanding industrial and machining applications. Sized at 2 mm (0.0790 inches) in diameter with a 3 mm straight-cylindrical shank, this bit delivers a 140-degree split-point geometry that improves centering and reduces thrust force at entry. The AlCrN coating provides oxidation resistance and extended tool life when cutting through abrasive workpiece materials. At 57 mm (2.244 inches) overall length, it fits standard toolholders used by machinists, maintenance technicians, and manufacturing professionals working with precision components.

This drill bit is designed for blind hole drilling and stack drilling operations. It performs on cast iron, non-ferrous metals, and steel workpieces, covering ISO material categories K, M, N, and P. The Series DB133-05 designation places it within a family of carbide drills built for short-to-medium depth hole work, with a maximum drilling depth of 14 mm (0.551 inches) and a flute-to-diameter ratio of 5xD. It suits CNC machining centers, drill presses, and manual machines where consistent diameter tolerance and hole finish are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• AlCrN coating extends tool life and performs well in dry or minimal-lubrication cutting conditions
• 140-degree Supreme point type improves self-centering and reduces walking on entry
• Straight-cylindrical shank (3 mm diameter) fits standard collets and drill chucks without adaptation
• Meets ANSI and ISO standards; diameter tolerance rated to m7 for consistent fit and bore quality
• Two-flute design optimized for chip evacuation in blind hole and stack drilling scenarios

Compatibility

Designed as an OEM-style replacement or direct-use carbide drill bit for applications requiring a 2 mm solid carbide jobber drill with a straight-cylindrical shank compatible with standard collet toolholders and drill chucks sized for 3 mm shanks.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals familiar with carbide tooling handling and machine setup procedures. Carbide is brittle - avoid side loads and lateral deflection that can cause chipping or fracture. Ensure the machine spindle and toolholder are clean and properly torqued before seating the shank. Follow applicable ANSI machining safety standards and machine manufacturer guidelines for spindle speed and feed rate selection.
