Walter-titex 5057061 Screw Machine Drill Bit 0.221 in

Product Description

The WALTER-TITEX 5057061 is a screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. Ground from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit delivers heat resistance and edge retention across a wide range of workpiece materials. The 130-degree split point minimizes walking and reduces thrust at entry. With a parabolic flute geometry and web-thinned, tapered web configuration, the 5057061 clears chips efficiently and maintains cutting stability at depth. It measures 2-19/32 inches overall length with a 0.221-inch diameter and is suited for machinists, tool and die technicians, and maintenance pros who need reliable performance in tight-tolerance bores.

This screw machine drill bit is rated for use on cast iron, stainless steel, hardened materials, non-ferrous metals, and general steel. Its compact screw machine length makes it well suited for drill press work, CNC machining centers, and manual drilling operations where stub-length rigidity is preferred over a jobber-length bit. The Series A1148 designation places it within a defined performance family built to DIN and ISO standards, making it a recognized fit for shops that specify tooling to those designations. Maximum drilling depth is 0.700 inches, with a flute-to-diameter ratio of 3xD.

Key Features

• Cobalt Vanadium High Speed Steel construction for elevated heat and wear resistance
• 130-degree split point reduces entry thrust and prevents bit walking
• Parabolic flute geometry with tapered web for efficient chip evacuation
• Screw machine (stub) length provides added rigidity over jobber-length bits
• Right-hand cut with straight-cylindrical shank for standard chuck compatibility
• Manufactured to DIN and ISO standards; BS and DIN specification designations

Compatibility

Designed for use on cast iron, hard materials, non-ferrous metals, stainless steel, and general steel. Compatible with standard drill chucks and CNC tool holders that accept straight-cylindrical shanks at 0.221-inch diameter. Conforms to DIN and ISO standards as part of the WALTER-TITEX Series A1148 line.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety practices. Ensure the drill chuck or collet is fully secured before operation and that workpiece material is firmly clamped. Do not exceed the recommended maximum drilling depth of 0.700 inches for this bit size. Inspect the cutting edges for wear before each use and replace when edge integrity is compromised to avoid oversized holes or tool breakage.
