Walter-titex 5058764 Jobber Drill Bit 4.9mm Hss Oxide

Product Description

The WALTER-TITEX 5058764 is a jobber-length drill bit designed for general-purpose drilling in ferrous metals, including cast iron and steel. Built from high speed steel (HSS) with an oxide coating, it runs at 4.9 mm (0.1929 inches) in diameter and measures 3-25/64 inches overall. The 118-degree standard point angle and web-thinned tip reduce entry thrust and improve centering on flat or curved surfaces. The regular spiral flute with a 2-flute configuration clears chips efficiently during through-hole and blind-hole operations. Licensed trades and maintenance machinists working in production or field environments will find this bit suited to both stack drilling and single-pass blind-hole work.

This drill bit is rated for use in cast iron and steel workpieces and is classified for Series A1211 applications. Its straight-cylindrical shank seats in standard drill chucks without adapters, making it compatible with handheld drills, drill presses, and CNC drilling setups. The 8xD flute-to-diameter ratio and 44 mm maximum drilling depth support deeper cuts relative to bit diameter. Typical use cases include structural fabrication, maintenance repair, and light production work where consistent hole quality in ferrous materials is required.

Key Features

• 4.9 mm (0.1929 inches) diameter with h8 tolerance for close-fit hole applications
• 118-degree standard point angle with web-thinned, tapered web for reduced entry force
• High speed steel construction with oxide coating for heat and wear resistance
• Regular spiral, 2-flute design supports efficient chip evacuation in cast iron and steel
• Straight-cylindrical shank fits standard chucks without adapters
• Rated for blind hole and stack drilling applications per ANSI and ISO standards

Compatibility

Designed for drilling cast iron and steel workpieces. Compatible with standard drill chucks accepting a 0.1929-inch straight-cylindrical shank. Conforms to ANSI, ISO, BS, and DIN specification designations for jobber-length drill bits in the 4.00 mm to 5.00 mm size range.

Installation Notes

This bit is installed and replaced by machinists, millwrights, or general maintenance technicians. Secure the straight-cylindrical shank firmly in the drill chuck before operation and confirm chuck key is removed prior to startup. Power down the drill or CNC spindle completely before changing bits. Do not exceed the rated maximum drilling depth of 44 mm (1.732 inches) in a single pass without retracting to clear chips.
