Walter-titex 5062540 Extra Length Drill Bit 0.25 in Hss

Product Description

The WALTER-TITEX 5062540 is an extra length, high speed steel (HSS) twist drill bit designed for deep-hole and stack drilling applications in metal fabrication and machining environments. It features a 0.25 inch diameter, a parabolic flute geometry, and a 130-degree split point for improved chip evacuation and reduced walking on entry. The overall length of 8-15/32 inches and a flute length of 5-29/32 inches allow this bit to reach depths that standard-length drills cannot. A web-thinned, tapered web configuration reduces thrust requirements. This tool is typically installed and used by machinists, tool-and-die technicians, and maintenance mechanics working with ferrous and non-ferrous metals.

This drill bit is suited for blind hole drilling and stack drilling operations on cast iron, non-ferrous metals, steel, cobalt alloys, iron, nickel, and titanium alloys. The Series A1622 designation places it in WALTER-TITEX's high-performance category. Its 16xD flute-to-diameter ratio supports a maximum drilling depth of 5.472 inches (139.00 mm), making it appropriate for deep-reach work in structural components, fixtures, and assemblies where standard-length bits fall short.

Key Features

• Parabolic flute geometry promotes efficient chip evacuation in deep-hole applications
• 130-degree drill point angle reduces thrust and improves hole entry accuracy
• Web-thinned tapered web lowers cutting resistance on tough alloys
• Uncoated HSS construction — compatible with standard regrinding and resharpening
• Straight-cylindrical shank fits standard drill chucks and collet holders sized for 0.25 inch shanks
• Meets ANSI, DIN 1869-I, and ISO standards for extra length drill geometry
• Right-hand cutting direction; suitable for blind hole and stack drilling operations

Compatibility

Rated for use on cast iron, non-ferrous metals, and steel as primary workpiece materials; secondary workpiece materials include cobalt, iron, nickel, and titanium alloys. Fits any drill press, milling machine spindle, or hand drill with a standard 0.25 inch capacity chuck or collet.

Installation Notes

Always secure the workpiece firmly before drilling and confirm the spindle speed is appropriate for the workpiece material and drill diameter. Use cutting fluid or coolant where the workpiece material and setup permit, even though this bit does not have through-coolant capability. Inspect the drill point for wear before each use, and regrind using appropriate HSS tooling when the cutting edge shows signs of dulling. Follow applicable ANSI safety standards for machine guarding and personal protective equipment during drilling operations.
