Walter-titex 5153739 Screw Machine Drill Bit 0.413 in

Product Description

The WALTER-TITEX 5153739 is a screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit measures 0.413 inches in diameter with an overall length of 3.5 inches and a flute length of 1.6875 inches. The 130-degree split point reduces walking and decreases feed force on entry. A parabolic flute geometry promotes efficient chip evacuation, making it well suited for deep-hole and production drilling. Straight-cylindrical shank construction ensures secure chuck engagement in standard drill presses and hand-held power tools. Licensed tradespeople and machinist-level technicians are the primary users of this tool.

This bit is engineered for universal performance across a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. Screw machine length geometry keeps the bit compact and rigid, reducing deflection in short-reach applications and production environments. The parabolic flute-to-diameter ratio of 3xD supports consistent chip flow at the maximum drilling depth of 1.1 inches. The web-thinned, tapered web configuration lowers cutting resistance and extends tool life in repetitive drilling cycles. This bit is appropriate for both job-shop use and CNC or manual drill press operations where tight diameter tolerances are required.

Key Features

• Cobalt Vanadium High Speed Steel construction for elevated heat and wear resistance
• 130-degree split point reduces drill walking and minimizes entry burr
• Parabolic flute design promotes aggressive chip evacuation in deep holes
• Web-thinned, tapered web lowers cutting resistance and reduces required feed force
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets DIN, ISO, and BS specification standards for dimensional accuracy

Compatibility

Designed as an OEM-style screw machine length drill bit suitable for use with standard three-jaw drill chucks on drill presses, CNC machining centers, and handheld power tools accepting straight-cylindrical shanks in the 0.413-inch diameter range. Compatible with workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals as specified by the manufacturer.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with metal drilling operations. Secure the shank fully in the chuck jaws and verify runout before beginning a drilling cycle. Always use appropriate cutting fluid or lubricant for the workpiece material to preserve edge life, particularly when drilling stainless steel or hard alloys. Power down and de-energize the machine spindle completely before changing or inspecting the bit.
