Walter-titex 5058378 Jobber Drill Bit No. 9 Hss

Product Description

The WALTER-TITEX 5058378 is a jobber length drill bit designed for general-purpose drilling in steel and cast iron. It measures 0.1960 inches in diameter (wire gauge No. 9) with an overall length of 3.375 inches and a flute length of 2.0625 inches. The bit is manufactured from high speed steel with an oxide coating to reduce friction and extend tool life. The 118-degree standard point geometry and web-thinned, tapered web configuration support clean entry and efficient chip evacuation. This bit is suited for production and maintenance drilling work performed by machinists, toolroom technicians, and general metalworking trades.

The 5058378 is built for blind hole and stack drilling applications in cast iron and steel workpieces. Its regular spiral flute geometry and 8xD flute-to-diameter ratio support controlled chip flow in both through-hole and stopped-bore conditions. The straight-cylindrical shank (0.1960 inches diameter) seats directly in standard drill chucks and collet holders without adapters. This bit meets ANSI and ISO standards and carries BS and DIN specification designations, making it appropriate for both domestic and international shop environments.

Key Features

• High speed steel construction with oxide coating for reduced friction in ferrous materials
• 118-degree standard drill point with web thinning for easier penetration and reduced thrust
• Tapered web and regular spiral flute for consistent chip evacuation in blind hole and stack drilling
• Straight-cylindrical shank fits standard drill chucks and collet holders directly
• Conforms to ANSI, ISO, BS, and DIN standards for dimensional consistency
• 2-flute design optimized for steel and cast iron workpieces

Compatibility

Designed as a general-purpose OEM-style jobber length drill bit for use in standard drill chucks and collet systems capable of accepting a 0.1960-inch straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking technicians familiar with drill press, CNC, or hand-drill operation. Ensure the spindle or chuck is fully de-energized and at rest before installing or removing the bit. Secure the shank firmly in the chuck or collet to the depth specified by the toolholder manufacturer to prevent slippage. No coolant-through capability is present on this bit; apply cutting fluid externally when drilling steel or cast iron to manage heat and extend tool life.
