Walter-titex 5058717 Jobber Drill Bit 3.1mm Hss Oxide

Product Description

The WALTER-TITEX 5058717 is a jobber-length twist drill bit designed for general-purpose hole-making in ferrous metals. Built from high speed steel with an oxide coating, it delivers reliable performance in cast iron and steel applications. The bit measures 3.1 mm (0.1220 inches) in diameter with an overall length of 65 mm (2-9/16 inches) and a 36 mm flute length. The 118-degree standard point and web-thinned, tapered web geometry reduce entry force and improve chip evacuation. This is a right-hand, spiral-flute tool suited for production and maintenance drilling in metal fabrication, HVAC component manufacturing, plumbing fixture shops, and general trade work.

The 5058717 is rated for blind hole drilling and stack drilling operations in cast iron and steel workpieces. Its straight-cylindrical shank (0.1220 inches diameter) fits standard keyless and keyed drill chucks without adapters. The regular spiral and 8xD flute-to-diameter ratio keep chips moving out of deep holes up to 30 mm (1.181 inches) maximum drilling depth. Series A1211 bits are built to ANSI and ISO standards and carry BS and DIN specification designations, making them appropriate for shops that work to either North American or European tolerance requirements.

Key Features

• High speed steel construction with oxide coating for wear resistance in ferrous metal drilling
• 118-degree standard point angle for broad material compatibility across cast iron and steel
• Web-thinned, tapered web reduces thrust load and improves chip flow at the point
• Right-hand, regular spiral flute with 8xD ratio supports chip evacuation in blind holes
• Straight-cylindrical shank at 0.1220 inches fits standard drill chucks directly
• Built to ANSI and ISO standards with BS and DIN specification compliance

Compatibility

Designed for use in cast iron and steel workpieces. Rated for blind hole and stack drilling applications per Series A1211 specifications. Fits any drill press, hand drill, or CNC spindle accepting a 0.1220-inch straight-cylindrical shank.

Installation Notes

Install in a properly sized chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid or coolant where possible to extend tool life, noting this bit does not support through-coolant. Inspect the cutting edges before each use and replace the bit if the point shows chipping or excessive wear.
