Walter-titex 5062502 Extra Length Drill Bit 0.189 in Hss

Product Description

The WALTER-TITEX 5062502 is an extra length, high speed steel (HSS) twist drill bit designed for deep-hole and extended-reach drilling applications. Built to Series A1622 and conforming to DIN 1869-I, ANSI, and ISO standards, this bit features a parabolic flute geometry and a 130-degree drill point angle for efficient chip evacuation and reduced thrust. At 0.189 inches (Wire Size 12) in diameter with an overall length of 7.688 inches and a flute length of 5.313 inches, it delivers a maximum drilling depth of 5.0 inches. The M2 HSS material grade and web-thinned, tapered web construction make it well-suited for production drilling in demanding materials. Installed by machinists, tool-and-die technicians, and maintenance professionals.

The 5062502 is rated for use in cast iron, non-ferrous metals, and steel as primary workpiece materials, with secondary compatibility in cobalt alloys, iron, nickel, and titanium alloys. The straight-cylindrical shank seats cleanly in standard drill chucks and collet holders. The 16xD flute-to-diameter ratio supports blind hole and stack drilling scenarios where a standard-length bit cannot reach. Right-hand cutting direction. Uncoated finish. Parabolic flute promotes fast chip removal in deep-hole passes without coolant-through capability, making it appropriate for manual or CNC operations where external coolant or dry cutting is standard practice.

Key Features

• Parabolic flute design promotes aggressive chip evacuation in deep holes up to 5.0 inches
• 130-degree split point angle reduces walking and lowers axial thrust on entry
• Web-thinned, tapered web reduces cutting resistance and improves centering
• M2 high speed steel construction provides toughness across a broad range of workpiece materials
• Conforms to DIN 1869-I, ANSI, and ISO specifications for consistent dimensional accuracy
• Straight-cylindrical shank compatible with standard chucks and collet systems

Compatibility

Designed for drilling cast iron, non-ferrous metals, and steel as primary materials, with secondary suitability for cobalt alloys, nickel, iron, and titanium alloys. Suitable for blind hole and stack drilling operations per Series A1622 application ratings.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance technicians familiar with drilling operations and machine safety protocols. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the straight-cylindrical shank fully within the chuck or collet to the correct grip depth before operating. This bit does not support coolant-through delivery; apply external coolant or cutting fluid at the entry point as required by the workpiece material and depth of cut.
