Walter-titex 5057094 Screw Machine Drill Bit 0.2055 in

Product Description

The WALTER-TITEX 5057094 is a screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. Measuring 0.2055 inches in diameter (Wire Size 5), it is constructed from cobalt and vanadium high speed steel for extended tool life when cutting hard and abrasive materials. The 130-degree split point reduces walking at entry and lowers thrust force, while the parabolic flute geometry promotes efficient chip evacuation. The bright, uncoated finish makes it easy to inspect for wear. At 2.4375 inches overall length with a 1.03125-inch flute length, this stub-length bit offers rigidity in close-quarter setups. It is suited for machinists, fabricators, and industrial maintenance technicians working with drill presses, CNC machines, and handheld power tools.

This drill bit is intended for right-hand cutting in a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. The screw machine (stub) length makes it a practical choice for production drilling environments where tool deflection and chatter must be minimized. The Series A1148 designation places it within a standardized cobalt high speed steel product family engineered for universal performance across varied substrates. A maximum drilling depth of 0.700 inches supports typical through-hole and blind-hole operations in plate, bar stock, and machined components. This bit is sold individually.

Key Features

• 0.2055 inch diameter (Wire Size 5) with tight diameter tolerance of -0.00071 to 0.00000 inches
• Cobalt and vanadium high speed steel construction for heat resistance and extended edge life
• 130-degree split point reduces entry thrust and prevents bit walking on hard surfaces
• Parabolic flute design with web thinning and tapered web for fast chip removal and reduced heat buildup
• Straight-cylindrical shank fits standard keyless and keyed drill chucks without adapters
• Conforms to DIN, ISO, and BS standards under Series A1148

Compatibility

Designed as an OEM-style replacement or direct-use drill bit compatible with standard straight-shank drill chucks on drill presses, CNC drilling machines, and handheld power tools. Suitable for use in steel, stainless steel, cast iron, hard materials, and non-ferrous metals as stated by the manufacturer.

Installation Notes

This bit is installed by machinists and maintenance technicians using standard drill chuck equipment. Ensure the chuck is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Use appropriate cutting fluid or coolant for stainless steel and hard material applications to preserve cutting edge life, even though the bit does not support internal coolant delivery. Inspect the cutting edges and split point before each use and replace the bit if chipping or excessive wear is observed.
