Walter-titex 5337297 Cobalt Drill Bit Wire 27 0.1440 in

Product Description

The WALTER-TITEX 5337297 is a cobalt jobber length drill bit designed for high-performance drilling in demanding materials. Built to M35 cobalt steel with an AlCrN coating, it delivers extended tool life when cutting cast iron, stainless steel, carbon steel, and non-ferrous metals. The bit features a 130-degree split point with web thinning for reduced thrust and accurate starting without a center punch. At 2.756 inches overall length with a 1.535-inch parabolic flute, it handles both blind hole drilling and stack drilling applications where chip evacuation and heat resistance are critical. Licensed contractors and machinists working in metal fabrication, HVAC equipment manufacturing, and mechanical service rely on this geometry for consistent hole quality.

This drill bit suits production and maintenance drilling in residential and commercial mechanical applications involving cast iron, stainless steel, and structural steel. The parabolic flute profile at a 5xD ratio promotes efficient chip removal at higher feed rates. The straight-cylindrical shank fits standard 3-jaw drill chucks and CNC tool holders with a 0.1440-inch shank diameter. It is appropriate for blind holes and stack drilling scenarios where precise exit geometry and consistent performance across multiple workpieces are required.

Key Features

• M35 cobalt steel construction resists heat buildup during aggressive cutting in hardened and abrasion-resistant materials
• AlCrN coating reduces friction and extends cutting life in cast iron, stainless steel, and steel workpieces
• 130-degree point angle with web thinning and UFL point type reduces entry thrust and improves self-centering
• Parabolic flute design at 5xD ratio improves chip evacuation in deep blind holes and stack drilling
• Straight-cylindrical shank at 0.1440 inch diameter fits standard drill chucks and CNC spindles
• Meets DIN 338, ANSI, and ISO standards for dimensional accuracy and performance consistency

Compatibility

Designed for use in standard drill chucks and CNC machining centers accepting a 0.1440-inch straight-cylindrical shank. Rated for primary workpiece materials including cast iron, non-ferrous metals, stainless steel, and steel per material codes K, M, N, and P.

Installation Notes

Installation and use should be performed by a qualified machinist or licensed trade technician familiar with metalworking drill press or CNC equipment. Secure the workpiece and verify chuck runout before drilling to maintain hole tolerance within the h8 specification. This bit does not support coolant-through delivery; use an external cutting fluid appropriate for the workpiece material. Follow ANSI and ISO safe machining practices and wear appropriate PPE including eye protection when operating.
