Walter-titex 5062511 Extra Length Drill Bit 0.161 in Hss

Product Description

The WALTER-TITEX 5062511 is an extra length high speed steel (HSS) drill bit designed for deep-hole and extended-reach drilling applications. Built from M2 grade HSS in an uncoated finish, this bit features a parabolic flute geometry and a web-thinned, tapered web configuration that improves chip evacuation and reduces thrust in demanding materials. The 130-degree split point (UFL type) provides accurate self-centering and clean entry. At 0.161 inches in diameter with an overall length of 6.875 inches and a flute length of 4.75 inches, the 5062511 delivers a 16xD flute-to-diameter ratio suited for blind hole and stack drilling where standard-length bits cannot reach.

This drill bit is intended for use by machinists, tool-and-die professionals, and maintenance technicians working in metal fabrication and production environments. Primary workpiece materials include cast iron, non-ferrous metals, and steel. Secondary materials include cobalt alloys, iron, nickel, and titanium alloys. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. Typical applications include blind hole drilling and stack drilling operations where extended reach and chip clearance are critical factors.

Key Features

• M2 high speed steel construction for wear resistance across a broad range of metals
• Parabolic flute design promotes efficient chip evacuation in deep holes
• Web-thinned tapered web reduces cutting forces and improves point stability
• 130-degree UFL split point for accurate self-centering and clean entry
• 16xD flute-to-diameter ratio supports maximum drilling depth of 4.449 inches
• Right-hand cutting direction with straight-cylindrical shank for broad chuck compatibility

Compatibility

Designed for use with standard drill chucks and collet systems accepting a 0.161-inch straight-cylindrical shank. Suitable for machining cast iron, non-ferrous metals, steel, cobalt alloys, nickel, and titanium alloys. Conforms to ANSI, DIN 1869-I, and ISO standards.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drill press or CNC drilling operations. Ensure the workpiece and spindle are fully secured before engaging the bit. No coolant-through capability is present on this bit, so external coolant or cutting fluid is recommended when drilling ferrous or hard alloys. Always verify chuck runout and shank seating before operation to protect the tight diameter tolerance of -0.00071 to 0.000 inches.
