Walter-titex 5057200 Screw Machine Drill Bit 0.1969in

Product Description

The WALTER-TITEX 5057200 is a screw machine length drill bit engineered for high-performance drilling across a wide range of materials. Built from Cobalt Vanadium High Speed Steel, the bit delivers the heat and wear resistance needed when working cast iron, stainless steel, hard materials, and non-ferrous metals. At 0.1969 inches in diameter with a 130-degree split point and parabolic flute geometry, it clears chips efficiently and reduces the thrust required to start and complete each hole. A web-thinned, tapered web configuration improves centering and lowers feed force. This bit is sized for production and maintenance environments where a compact, rigid screw machine length drill is required.

This drill bit is suited for machining operations on cast iron, stainless steel, hard alloys, and non-ferrous metals in both production and job-shop settings. The screw machine length format provides added rigidity over jobber-length bits, making it appropriate for drill presses, CNC machining centers, and turret lathes where runout control and consistent hole quality matter. The straight-cylindrical shank fits standard three-jaw and collet-style chucks without modification. Series A1148 establishes this bit within a standardized product family built to DIN and ISO dimensional standards.

Key Features

• Cobalt Vanadium High Speed Steel construction for heat resistance when drilling hard and abrasive materials
• 130-degree split point reduces walking and lowers required feed force at entry
• Parabolic flute geometry promotes fast chip evacuation and reduces heat buildup
• Web-thinned tapered web improves centering and extends tool life
• Bright/uncoated finish compatible with a broad range of cutting fluids and lubricants
• Meets DIN, ISO, and BS specification standards for dimensional consistency

Compatibility

Designed as an OEM-style replacement or direct-use screw machine drill bit for applications requiring a 0.1969-inch diameter hole in cast iron, hard materials, non-ferrous metals, stainless steel, and general steel workpieces. Fits any standard straight-cylindrical chuck or collet accepting a shank of equivalent diameter. Part of WALTER-TITEX Series A1148.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with rotary cutting tools. Before mounting, inspect the shank and flutes for damage and confirm the chuck or collet is clean and within proper runout tolerance. Always power down and lock out the machine spindle before changing tooling. Follow applicable shop safety standards and the machine manufacturer guidelines for speed and feed recommendations based on workpiece material.
